00:00:00.070 --> 00:00:04.459
You are listening to Interview Reactions and Analysis. Prepare for
2
00:00:04.500 --> 00:00:07.620
a deep dive into the most fascinating conversations.
3
00:00:08.259 --> 00:00:09.140
Here are your hosts.
4
00:00:09.619 --> 00:00:15.279
Imagine taking like a powerful immunosuppressant, a drug that was
5
00:00:15.339 --> 00:00:18.589
originally formulated to stop a patient's body from violently rejecting
6
00:00:18.629 --> 00:00:22.390
a transplanted kidney. Right. But taking it. Not because you're sick,
7
00:00:22.429 --> 00:00:24.250
but because you want to live to be, I don't know,
8
00:00:24.250 --> 00:00:27.300
120 years old. I mean, it sounds completely absurd, right,
9
00:00:27.339 --> 00:00:31.199
that the whole traditional medical consensus tells us to build
10
00:00:31.280 --> 00:00:35.020
up our defenses, to boost our immune system. Yet here
11
00:00:35.079 --> 00:00:38.880
is this philosophy advocating that we intentionally suppress those exact
12
00:00:38.950 --> 00:00:40.850
same defenses to extend our lives.
13
00:00:41.170 --> 00:00:43.969
It really does challenge the entire foundation of preventative medicine,
14
00:00:43.990 --> 00:00:46.810
doesn't it? I mean, we're so conditioned to view a
15
00:00:46.869 --> 00:00:49.890
suppressed immune system as the state of ultimate vulnerability, like
16
00:00:49.929 --> 00:00:52.969
a precursor to disease, not a shield against aging. But
17
00:00:53.229 --> 00:00:56.049
when you actually look closely at the biological mechanics of
18
00:00:56.119 --> 00:00:59.460
how we age, that vulnerability becomes the exact mechanism for longevity.
19
00:00:59.820 --> 00:01:03.539
Wow. Yeah. Welcome to the Deep Dive, everyone. Today is Saturday,
20
00:01:03.719 --> 00:01:07.000
July 11th, 2026. And we are sort of stepping into
21
00:01:07.049 --> 00:01:09.870
a time machine today to look back at a really
22
00:01:09.930 --> 00:01:14.409
specific cultural and scientific touchstone. We're looking at a multi-hour
23
00:01:14.469 --> 00:01:18.549
conversation from the Joe Rogan Experience, episode number 1108, which,
24
00:01:18.689 --> 00:01:21.010
if you can believe it, aired all the way back
25
00:01:21.129 --> 00:01:21.969
in 2018.
26
00:01:21.969 --> 00:01:24.769
And, you know, what's fascinating here is that specific year.
27
00:01:24.849 --> 00:01:29.359
It's crucial context. 2018 was this wild inflection point where
28
00:01:29.420 --> 00:01:33.180
the highly clinical, quantified approach to human longevity was just
29
00:01:33.200 --> 00:01:37.189
sort of beginning to break out of these hyper-specialized medical circles. and, well,
30
00:01:37.409 --> 00:01:38.810
into the broader public consciousness.
31
00:01:38.909 --> 00:01:41.430
Yeah, and the guest really driving that breakout was Dr.
32
00:01:41.469 --> 00:01:44.189
Peter Attia. Just to set the stage for you listening, Dr.
33
00:01:44.230 --> 00:01:46.769
Attia is the founder of Attia Medical PC. It's this
34
00:01:46.870 --> 00:01:49.730
highly specialized practice with offices in San Diego and New
35
00:01:49.750 --> 00:01:53.060
York City. And their mandate isn't treating the flu or
36
00:01:53.090 --> 00:01:56.219
managing standard chronic illnesses. Their entire clinical obsession is what
37
00:01:56.239 --> 00:01:57.980
they call the applied science of longevity.
38
00:01:58.500 --> 00:02:03.099
Exactly. And that phrase, applied science, is what separates it from, say,
39
00:02:03.459 --> 00:02:08.289
the theoretical biology happening in university labs. Adia Medical, PC,
40
00:02:08.909 --> 00:02:11.069
operates on this premise that we don't have to wait
41
00:02:11.110 --> 00:02:14.490
for some hypothetical longevity pill to drop in 50 years.
42
00:02:14.840 --> 00:02:19.099
We can manipulate cellular decay and biomechanical breakdown and metabolic
43
00:02:19.120 --> 00:02:24.840
dysfunction right now, today, using really aggressive, highly monitored interventions.
44
00:02:25.259 --> 00:02:28.919
Right. And in this 2018 conversation, Adia essentially opened the
45
00:02:28.960 --> 00:02:31.719
clinical fire hose on millions of listeners without dumbing down
46
00:02:31.759 --> 00:02:34.669
the biochemistry at all, which is wild. So our mission
47
00:02:34.689 --> 00:02:37.069
today is to extract the most critical insights from that
48
00:02:37.090 --> 00:02:39.990
massive discussion. We're going to explore the dietary architecture of
49
00:02:40.030 --> 00:02:43.830
living longer, the weird paradox of life-extending drugs, the mechanical
50
00:02:43.889 --> 00:02:46.030
engineering of the physical body, and, of course, some of
51
00:02:46.050 --> 00:02:49.050
the wild, bizarre conversational detours that happen when you sit
52
00:02:49.090 --> 00:02:50.370
down in that specific studio.
53
00:02:50.409 --> 00:02:51.469
Which are always the best parts.
54
00:02:51.610 --> 00:02:54.530
Oh, absolutely. So, okay, let's unpack this. The best place
55
00:02:54.550 --> 00:02:57.740
to start is probably where Atiyah anchors his own foundational protocols, right?
56
00:02:57.780 --> 00:03:00.900
The metabolic architecture of daily life. Specifically, the timing of
57
00:03:00.960 --> 00:03:01.439
what we eat.
58
00:03:01.800 --> 00:03:04.060
Yeah. This is where we run into a major conceptual
59
00:03:04.099 --> 00:03:07.659
collision right out of the gate. In the conversation, Adia
60
00:03:07.699 --> 00:03:12.599
draws a super rigid line between intermittent fasting and time-restricted feeding.
61
00:03:12.740 --> 00:03:14.780
Right. And I have to ask, because for you listening,
62
00:03:14.879 --> 00:03:17.319
does it really matter what we call it? Isn't fasting
63
00:03:17.379 --> 00:03:21.030
just fasting? Like if the result is just skipping breakfast
64
00:03:21.090 --> 00:03:25.210
and not eating your first meal until 1.000 p.m., the
65
00:03:25.289 --> 00:03:28.830
cells aren't looking at a dictionary, right? A caloric deficit
66
00:03:28.870 --> 00:03:29.949
is a caloric deficit.
67
00:03:30.419 --> 00:03:32.460
It's such a common assumption, and it makes sense on
68
00:03:32.479 --> 00:03:35.840
the surface. But in the applied science of longevity, confusing
69
00:03:35.860 --> 00:03:38.800
those two concepts is, well, it's like confusing a mild
70
00:03:38.840 --> 00:03:40.930
stretching routine with major orthopedic surgery.
71
00:03:41.069 --> 00:03:42.610
Wow, okay, that different.
72
00:03:42.629 --> 00:03:45.789
Yeah, they are biologically distinct interventions. Let's break down the
73
00:03:45.810 --> 00:03:50.229
mechanism of time-restricted feeding, or TRF. TRF is entirely about
74
00:03:50.289 --> 00:03:54.259
standardizing your daily eating window to align with your circadian biology.
75
00:03:54.479 --> 00:03:54.800
Okay.
76
00:03:55.099 --> 00:03:57.419
So you might be consuming a massive amount of calories,
77
00:03:57.840 --> 00:04:01.060
enough to maintain or even build muscle. But you're compressing
78
00:04:01.080 --> 00:04:04.680
that intake into, say, an eight-hour window, leaving 16 hours
79
00:04:04.719 --> 00:04:05.099
of rest.
80
00:04:05.400 --> 00:04:07.719
So it's not about starvation at all. It's just about
81
00:04:08.210 --> 00:04:09.229
the circadian clock.
82
00:04:09.310 --> 00:04:13.889
Precisely. Your metabolic machinery, I'm talking your liver, your pancreas,
83
00:04:14.409 --> 00:04:18.449
your gut microbiome, it all operates on a circadian rhythm.
84
00:04:19.009 --> 00:04:22.810
So when you practice time-restricted feeding, you are allowing hepatic
85
00:04:22.829 --> 00:04:25.939
glycogen levels, so the sugar in your liver, to deplete
86
00:04:26.040 --> 00:04:29.970
just enough to maintain insulin sensitivity. Right. And at the
87
00:04:30.009 --> 00:04:34.350
same time, you're giving the digestive tract a predictable daily
88
00:04:34.410 --> 00:04:37.410
period of downtime. It is just a chronic daily management
89
00:04:37.449 --> 00:04:38.879
tool for the biological clock.
90
00:04:39.000 --> 00:04:41.800
But then how does that differ biologically from intermittent fasting
91
00:04:41.899 --> 00:04:45.240
as Adia defines it? Because if I push that 16-hour
92
00:04:45.279 --> 00:04:48.339
window to, say, three or four days of zero calories,
93
00:04:48.680 --> 00:04:51.379
the mechanism must just be the same, just amplified, right?
94
00:04:51.399 --> 00:04:54.199
No, it isn't just an amplification. It's a total metabolic
95
00:04:54.240 --> 00:04:54.920
paradigm shift.
96
00:04:55.160 --> 00:04:55.860
Really? Yeah.
97
00:04:55.899 --> 00:04:58.000
When you push past that two- or three-day mark of
98
00:04:58.079 --> 00:05:01.930
zero caloric intake, You deplete your liver's glycogen stores completely.
99
00:05:02.569 --> 00:05:05.889
And that forces the body to undergo this profound evolutionary
100
00:05:05.930 --> 00:05:09.370
survival response. This is where you trigger deep autophagy.
101
00:05:09.470 --> 00:05:12.230
Okay, autophagy being the cellular house cleaning process.
102
00:05:12.430 --> 00:05:15.850
Yes, exactly. The literal translation is self-eating. So when the
103
00:05:15.889 --> 00:05:20.629
body detects a sustained critical lack of nutrients, specific signaling
104
00:05:20.670 --> 00:05:24.100
pathways like AMPK, they ramp up. And the cells actually
105
00:05:24.199 --> 00:05:24.959
stop divining.
106
00:05:25.120 --> 00:05:25.420
Oh, wow.
107
00:05:25.660 --> 00:05:28.699
Instead, they start scavenging their own interior environments. They break
108
00:05:28.750 --> 00:05:32.990
down misfolded proteins, dysfunctional mitochondria, all the cellular debris just
109
00:05:33.029 --> 00:05:36.569
to use it for basic energy survival. Time-restricted feeding rarely
110
00:05:36.610 --> 00:05:40.350
pushes the body into deep autophagy. It just manages daily insulin.
111
00:05:41.589 --> 00:05:44.189
Intermittent fasting, on the other hand, is a blunt force
112
00:05:44.269 --> 00:05:48.279
tool to clear out the cellular junk that literally causes aging.
113
00:05:48.600 --> 00:05:51.420
So if you're listening, think about your own schedule. If
114
00:05:51.439 --> 00:05:53.199
you are eating from the moment you wake up, having
115
00:05:53.220 --> 00:05:55.800
a snack at 10 a.m., a big lunch, dinner, and
116
00:05:55.839 --> 00:06:00.040
then a late-night snack, your body is perpetually flooded with nutrients.
117
00:06:00.120 --> 00:06:03.029
You are locked in this perpetual state of growth and storage.
118
00:06:03.269 --> 00:06:06.769
And in the context of longevity, chronic unchecked growth is
119
00:06:06.810 --> 00:06:11.310
the enemy. Constant nutrient signaling keeps a specific pathway. It's
120
00:06:11.329 --> 00:06:17.000
called MTR, permanently elevated. And when MTR is active, cells divide,
121
00:06:17.079 --> 00:06:21.220
tumors can grow. And the biological machine just prioritizes expansion
122
00:06:21.279 --> 00:06:21.819
over repair.
123
00:06:22.220 --> 00:06:25.139
Which brings us perfectly to the absolute wildest part of
124
00:06:25.160 --> 00:06:28.540
this discussion. We just established that fasting, you know, the
125
00:06:28.639 --> 00:06:33.339
literal deprivation of nutrients for days, suppresses that MTR pathway
126
00:06:33.379 --> 00:06:36.279
and forces the body to repair itself. But what if
127
00:06:36.319 --> 00:06:39.040
you could flip that genetic switch without having to starve
128
00:06:39.079 --> 00:06:39.579
for a week?
129
00:06:39.879 --> 00:06:40.759
Enter repamycin.
130
00:06:40.959 --> 00:06:44.319
Yes. This drug completely flips the script. I mean, the
131
00:06:44.439 --> 00:06:48.269
origins alone are fascinating. It's a compound originally discovered in
132
00:06:48.310 --> 00:06:51.250
the dirt, literally in the soil of Easter Island Rapa Nui,
133
00:06:51.529 --> 00:06:54.290
produced by a specific bacterium. And as we mentioned at
134
00:06:54.329 --> 00:06:56.810
the start of the show, its primary clinical application has
135
00:06:56.870 --> 00:07:00.860
been as a potent immune suppressant for organ transplant patients. Right.
136
00:07:00.899 --> 00:07:03.620
And this is exactly where the longevity paradox lies. The
137
00:07:03.680 --> 00:07:06.319
target that rapamycin binds to in the human body is
138
00:07:06.399 --> 00:07:09.259
so central to our biology that it was literally named
139
00:07:09.319 --> 00:07:12.139
after the drug. It's called the mechanistic target of rapamycin
140
00:07:12.160 --> 00:07:12.939
or MTOR.
141
00:07:13.370 --> 00:07:18.230
So the drug suppresses MTOR, which then dampens the immune system.
142
00:07:19.370 --> 00:07:20.870
But wait, this is the part I get stuck on.
143
00:07:21.290 --> 00:07:24.269
How does shutting down the immune system correlate with extending
144
00:07:24.329 --> 00:07:27.949
human life? Because we spend, I mean, billions of dollars
145
00:07:27.990 --> 00:07:31.509
globally on vitamin C and zinc and all these supplements
146
00:07:31.569 --> 00:07:33.459
trying to boost our immune systems.
147
00:07:33.699 --> 00:07:37.379
Yeah, it requires a complete reevaluation of what aging actually is.
148
00:07:37.839 --> 00:07:40.220
As we get older, our immune system doesn't just get weaker,
149
00:07:40.300 --> 00:07:44.149
it gets dysregulated. We accumulate these things called senescent cells.
150
00:07:44.389 --> 00:07:45.209
The zombie cells.
151
00:07:45.269 --> 00:07:48.209
Exactly, the zombie cells. They have stopped dividing, but they
152
00:07:48.350 --> 00:07:51.540
absolutely refuse to die. And they sit there and secrete
153
00:07:51.569 --> 00:07:55.180
this highly toxic cocktail of inflammatory cytokines.
154
00:07:55.300 --> 00:07:57.860
So they just sit in the tissue, basically polluting the
155
00:07:57.899 --> 00:07:58.939
local environment. Right.
156
00:07:59.060 --> 00:08:02.879
And your immune system, particularly these cells called macrophages, reacts
157
00:08:02.920 --> 00:08:05.339
to this toxic secretion by going into a state of
158
00:08:05.439 --> 00:08:10.329
chronic hyperactive overdrive. This constant low-grade inflammation is what actually
159
00:08:10.350 --> 00:08:14.910
drives heart disease and neurodegeneration joint decay. In the longevity space,
160
00:08:14.949 --> 00:08:16.870
it is widely referred to as inflammaging.
161
00:08:17.250 --> 00:08:18.120
Inflammaging, right.
162
00:08:18.519 --> 00:08:18.699
Okay.
163
00:08:19.259 --> 00:08:20.720
I want to try an analogy here to see if
164
00:08:20.759 --> 00:08:22.800
I have the mechanics of this right, because people always
165
00:08:22.839 --> 00:08:24.819
say it's like taking the brakes off the immune system,
166
00:08:24.920 --> 00:08:26.819
but that just never made sense to me.
167
00:08:26.860 --> 00:08:27.279
Let's hear it.
168
00:08:27.699 --> 00:08:30.149
To me, it sounds more like turning off the perimeter
169
00:08:30.189 --> 00:08:32.970
alarms at a military base. Like, as we get older,
170
00:08:32.990 --> 00:08:37.149
our immune system acts like a bunch of paranoid, sleep-deprived soldiers.
171
00:08:37.669 --> 00:08:41.039
They're shooting at shadows, throwing grenades at minor threats. And
172
00:08:41.090 --> 00:08:43.629
in the process, they are blowing up their own barracks
173
00:08:43.690 --> 00:08:48.350
and destroying the base. So rapamycin comes in, shuts off
174
00:08:48.389 --> 00:08:50.570
the blaring alarms, and tells the soldiers to put their
175
00:08:50.610 --> 00:08:53.110
weapons down and just start sweeping the floors.
176
00:08:53.490 --> 00:08:56.929
That is actually a much more accurate representation of the pharmacology.
177
00:08:56.990 --> 00:08:57.190
Yeah.
178
00:08:57.370 --> 00:09:01.009
By inhibiting MTOR with rapamycin, you are forcing the cells
179
00:09:01.070 --> 00:09:04.940
to stop their panicked hyperactive growth and secretion phases. You're
180
00:09:04.980 --> 00:09:08.899
dampening that friendly fire, which theoretically slows down the entire
181
00:09:09.000 --> 00:09:09.639
aging process.
182
00:09:10.159 --> 00:09:13.440
But there is a massive catch. And Attia, to his credit,
183
00:09:13.580 --> 00:09:15.960
doesn't shy away from it in the conversation. You can't
184
00:09:16.000 --> 00:09:19.629
just hack the MTR pathway without collateral damage. The source
185
00:09:19.649 --> 00:09:23.870
material dives into a very specific, weird side effect of rapamycin,
186
00:09:24.370 --> 00:09:25.250
aphthous ulcers.
187
00:09:25.509 --> 00:09:28.809
Which are essentially severe mouth sores or canker sores.
188
00:09:29.070 --> 00:09:31.720
Right. And I just found it so jarring that in
189
00:09:31.750 --> 00:09:35.820
this multi-hour discussion about extending human life to 120, they
190
00:09:35.840 --> 00:09:39.659
spent a significant chunk of time talking about canker sores. Like,
191
00:09:40.139 --> 00:09:44.220
Why is this hyperspecific mucosal irritation the focal point for
192
00:09:44.259 --> 00:09:45.299
a life-extending drug?
193
00:09:45.360 --> 00:09:48.169
Well, because aphthous ulcers serve as the ultimate biomarker for
194
00:09:48.190 --> 00:09:51.330
the drug's mechanism of action. Think about the mucosal lining
195
00:09:51.350 --> 00:09:54.250
of your mouth. It has one of the absolute fastest
196
00:09:54.370 --> 00:09:57.789
cellular turnover rates in the entire human body. Those cells
197
00:09:57.830 --> 00:09:59.970
are constantly, constantly dividing and replacing themselves.
198
00:10:00.360 --> 00:10:02.279
What if it's eating and talking and all that?
199
00:10:02.399 --> 00:10:05.019
Exactly. So when you introduce a drug like rapamycin, which
200
00:10:05.100 --> 00:10:09.320
fundamentally halts cellular growth and replication, those rapidly dividing cells
201
00:10:09.360 --> 00:10:11.179
in the mouth are the very first ones to suffer.
202
00:10:11.340 --> 00:10:14.240
They just can't replicate fast enough to heal the normal
203
00:10:14.279 --> 00:10:16.039
wear and tear, so the ulcers form.
204
00:10:16.179 --> 00:10:20.549
Precisely. And in the clinical setting of antiemetical, PC, The
205
00:10:20.649 --> 00:10:23.350
presence of these ulcers isn't just, you know, an annoying
206
00:10:23.429 --> 00:10:26.799
side effect. It is proof of concept. It confirms that
207
00:10:26.840 --> 00:10:30.799
the drug is actually in the system actively suppressing MTOR.
208
00:10:31.340 --> 00:10:35.659
It really represents the razor's edge of longevity pharmacology. you
209
00:10:35.720 --> 00:10:39.799
are deliberately inducing a toxic effect to achieve a long-term
210
00:10:39.919 --> 00:10:41.419
biological recalibration.
211
00:10:41.570 --> 00:10:44.789
That fundamentally changes the philosophy of what a doctor even is.
212
00:10:44.909 --> 00:10:47.509
I mean, for centuries, medicine has been entirely reactive. You
213
00:10:47.529 --> 00:10:50.090
have a bacterial infection. The doctor gives you penicillin to
214
00:10:50.129 --> 00:10:52.429
kill it. You have a ruptured appendix. The surgeon cuts
215
00:10:52.470 --> 00:10:54.830
it out. The whole goal is to return a sick
216
00:10:54.870 --> 00:10:58.690
person to baseline. But prescribing a powerful immunosuppressant to a
217
00:10:58.830 --> 00:11:03.470
perfectly healthy 40-year-old, you're using aggressive pharmacology not to fix
218
00:11:03.490 --> 00:11:07.169
the disease, but to manipulate the fundamental architecture of time.
219
00:11:07.690 --> 00:11:11.529
It is the transition from disease management to biological engineering.
220
00:11:12.389 --> 00:11:15.690
But as you can imagine, this presents a massive clinical bottleneck.
221
00:11:16.210 --> 00:11:18.889
If you are prescribing a drug to delay aging, how
222
00:11:18.909 --> 00:11:20.029
do you even measure success?
223
00:11:20.149 --> 00:11:22.350
Right, because humans live for eight decades.
224
00:11:22.590 --> 00:11:26.450
Exactly. You cannot run a standard double-blind clinical trial that
225
00:11:26.490 --> 00:11:28.440
spans a century. By the time the data comes in,
226
00:11:28.889 --> 00:11:30.220
the researchers themselves are dead.
227
00:11:30.509 --> 00:11:33.360
That is the ultimate bottleneck. And it explains why the
228
00:11:33.399 --> 00:11:37.240
conversation takes a somewhat, I don't know, sobering turn toward
229
00:11:37.259 --> 00:11:39.940
the animals sleeping at the foot of our beds. They
230
00:11:39.980 --> 00:11:44.399
spend time discussing a very specific compressed mortality model, which
231
00:11:44.480 --> 00:11:45.259
is dogs.
232
00:11:45.559 --> 00:11:48.690
Yet looking at canine aging is not just a sentimental exercise.
233
00:11:49.230 --> 00:11:51.830
It is a highly critical scientific tool in this field.
234
00:11:52.590 --> 00:11:56.629
Dogs offer a unique, accelerated window into mammalian biology.
235
00:11:56.769 --> 00:11:59.940
Because their lifespans are roughly a decade. In 12 years,
236
00:12:00.159 --> 00:12:02.539
a large breed dog goes from a newborn puppy to
237
00:12:02.580 --> 00:12:06.299
an elite athlete in its prime, straight into senior cognitive decline,
238
00:12:06.460 --> 00:12:09.570
joint failure, and terminal disease. It's incredibly fast.
239
00:12:09.990 --> 00:12:14.529
And crucially, they share our exact environment. This is key.
240
00:12:15.409 --> 00:12:18.850
Unlike a laboratory mouse kept in a sterile, temperature-controlled box
241
00:12:19.169 --> 00:12:22.629
eating highly processed pellets, dogs live in our homes.
242
00:12:23.169 --> 00:12:23.529
Right.
243
00:12:23.570 --> 00:12:26.399
They are exposed to the exact same off-gassing from our carpets,
244
00:12:26.820 --> 00:12:30.440
the same circadian disruptions from artificial lighting, the same water supply,
245
00:12:30.960 --> 00:12:33.950
and often similar psychological stressors from the household.
246
00:12:34.090 --> 00:12:38.190
They are basically running the human aging program on fast forward. Exactly.
247
00:12:38.889 --> 00:12:41.889
When an applied longevity researcher studies how a dog's joints
248
00:12:41.929 --> 00:12:45.139
degrade or how their immune system succumbs to canine cancer,
249
00:12:45.700 --> 00:12:48.799
they are observing the vulnerabilities of the mammalian chassis in
250
00:12:48.899 --> 00:12:52.580
real time. Much of the data regarding MTOR inhibition and
251
00:12:52.620 --> 00:12:56.000
rapamycin's efficacy actually stems from the Dog Aging Project.
252
00:12:56.059 --> 00:12:56.360
Really?
253
00:12:56.379 --> 00:12:58.679
Oh, yeah. Because you can administer the drug to a
254
00:12:58.720 --> 00:13:03.250
middle-aged dog and see definitive, measurable impacts on cardiac function
255
00:13:03.299 --> 00:13:05.529
and cognitive health within just two or three years.
256
00:13:05.850 --> 00:13:08.389
Wow. And, you know, while it can be heavy to
257
00:13:08.429 --> 00:13:11.789
think about the mortality of our pets, there is a
258
00:13:12.009 --> 00:13:16.360
beautiful reciprocity here. The interventions we test to understand human
259
00:13:16.480 --> 00:13:19.620
aging are simultaneously providing therapies that might give us an
260
00:13:19.659 --> 00:13:22.220
extra three or four healthy years with our dogs. It's
261
00:13:22.259 --> 00:13:25.539
this really elegant overlap of science and companionship.
262
00:13:25.779 --> 00:13:29.230
It is. But studying the biochemical decay of a dog
263
00:13:29.309 --> 00:13:32.309
or a human brings us to a really harsh reality
264
00:13:32.350 --> 00:13:36.230
in the longevity space. Cellular aging is only half the equation.
265
00:13:36.669 --> 00:13:39.809
You can have the pristine, empty, or suppressed biochemistry of
266
00:13:39.850 --> 00:13:42.889
a 30-year-old. But if your hip joint is structurally ground
267
00:13:42.929 --> 00:13:46.509
to dust, or your lumbar spine is completely collapsed, your
268
00:13:46.549 --> 00:13:48.019
health span is effectively over.
269
00:13:48.450 --> 00:13:50.769
Oh man, that is the nightmare scenario, isn't it? Living
270
00:13:50.809 --> 00:13:53.549
to 110 but spending the last three decades trapped in
271
00:13:53.590 --> 00:13:57.690
a wheelchair because your structural engineering failed? Biochemistry is absolutely
272
00:13:57.809 --> 00:13:59.149
useless without biomechanics.
273
00:13:59.250 --> 00:14:02.169
Which is why the diagnostic landscape of longevity requires a
274
00:14:02.250 --> 00:14:05.350
massive shift from the microscopic to the macroscopic. And it's
275
00:14:05.370 --> 00:14:07.809
why the tools at a clinic like Atia's seem more
276
00:14:07.889 --> 00:14:11.490
suited to an Olympic training center than a traditional doctor's office.
277
00:14:11.990 --> 00:14:14.169
Yes, let's talk about the force plate treadmill because this
278
00:14:14.210 --> 00:14:17.240
piece of equipment is fascinating. Most people think of a
279
00:14:17.269 --> 00:14:19.779
treadmill as just a moving belt to get your heart
280
00:14:19.820 --> 00:14:23.159
rate up and burn some calories. Why does an applied
281
00:14:23.220 --> 00:14:28.450
longevity physician need a highly specialized, insanely expensive force plate system?
282
00:14:28.850 --> 00:14:33.190
Because gravity is the ultimate inescapable stressor on the human body.
283
00:14:33.889 --> 00:14:36.850
A force plate treadmill doesn't just measure your cardiovascular output.
284
00:14:37.460 --> 00:14:41.740
It maps the exact ground reaction forces of every single
285
00:14:41.799 --> 00:14:42.370
foot strike.
286
00:14:42.539 --> 00:14:43.850
Okay, what does that mean in practice?
287
00:14:44.149 --> 00:14:47.549
It measures the milliseconds of contact time, the asymmetrical loading
288
00:14:47.590 --> 00:14:50.210
between your left and right leg, and the sheer force
289
00:14:50.289 --> 00:14:52.649
transmitted up through your entire kinematic chain.
290
00:14:52.809 --> 00:14:55.690
So it's diagnosing microscopic imbalances. Like, let's say you have
291
00:14:55.730 --> 00:14:58.769
a 3% discrepancy in how your right foot absorbs shock
292
00:14:58.850 --> 00:15:01.500
compared to your left. If you run 3 miles a
293
00:15:01.500 --> 00:15:05.240
day for 20 years, that tiny 3% asymmetry compounds over
294
00:15:05.419 --> 00:15:06.620
millions of repetitions.
295
00:15:07.299 --> 00:15:11.480
And it results in a catastrophic structural failure, a torn meniscus,
296
00:15:12.019 --> 00:15:16.259
a degraded hip labrum, or severe lower back trauma. The
297
00:15:16.320 --> 00:15:18.580
force plate allows a physician to look at a perfectly
298
00:15:18.620 --> 00:15:22.580
healthy 40-year-old patient and say, your biochemistry is fine, but
299
00:15:22.600 --> 00:15:24.409
the way your foot hits the ground is going to
300
00:15:24.419 --> 00:15:27.250
require a hip replacement by age 65.
301
00:15:27.250 --> 00:15:29.350
So they have to correct the movement pattern before the
302
00:15:29.370 --> 00:15:33.470
damage accrues. And this highlights a fascinating theme in Atiyah's approach.
303
00:15:34.049 --> 00:15:37.330
He talks about seeking out the guru of speed. He
304
00:15:37.529 --> 00:15:41.330
actively consults with sprint coaches and biomechanics experts who train
305
00:15:41.370 --> 00:15:42.690
the fastest humans on Earth.
306
00:15:42.970 --> 00:15:46.009
Which might seem completely counterintuitive for a longevity patient who
307
00:15:46.049 --> 00:15:48.710
just wants to play with their grandchildren, not run a
308
00:15:48.809 --> 00:15:53.570
sub-10-second 100-meter dash. But the underlying logic is profound. A
309
00:15:53.669 --> 00:15:56.950
guru of speed is a master of mechanical efficiency.
310
00:15:57.269 --> 00:16:01.629
Right, because elite sprinters cannot afford leaked energy or structural imbalances,
311
00:16:02.090 --> 00:16:04.750
or they literally tear their hamstrings to shreds on the track.
312
00:16:05.070 --> 00:16:10.159
Exactly. By studying the absolute pinnacle of human movement, longevity
313
00:16:10.299 --> 00:16:13.730
experts can reverse engineer those mechanics to teach a 50-year-old
314
00:16:13.759 --> 00:16:16.710
how to walk, run, and carry weight safely for the
315
00:16:16.750 --> 00:16:17.629
next 50 years.
316
00:16:17.950 --> 00:16:20.809
And the ultimate application of carrying weight safely brings us
317
00:16:20.850 --> 00:16:24.190
to what might be the cornerstone of physical longevity training
318
00:16:24.230 --> 00:16:28.169
and its protocols, the hex bar deadlift. If you think
319
00:16:28.210 --> 00:16:30.620
a deadlift is just picking up a heavy barbell to
320
00:16:30.669 --> 00:16:33.340
build big muscles for the beach, you are missing the
321
00:16:33.399 --> 00:16:34.679
entire architectural point.
322
00:16:35.090 --> 00:16:37.169
To really understand the hex bar, we first have to
323
00:16:37.210 --> 00:16:40.789
understand the inherent risk of the traditional straight bar deadlift.
324
00:16:41.350 --> 00:16:43.690
When you walk up to a standard barbell, the weight
325
00:16:43.730 --> 00:16:46.629
is positioned entirely in front of your shins. As you
326
00:16:46.649 --> 00:16:49.070
bend down to grip it, the lever arm between the
327
00:16:49.129 --> 00:16:51.470
weight and your lower back creates a massive amount of
328
00:16:51.529 --> 00:16:53.230
sheer force on the lumbar spine.
329
00:16:53.769 --> 00:16:57.029
Sheer force meaning the vertebrae are being pulled horizontally, trying
330
00:16:57.049 --> 00:16:58.250
to slide past one another.
331
00:16:58.509 --> 00:17:02.529
Correct. It is a phenomenal exercise for posterior chain development.
332
00:17:03.230 --> 00:17:07.109
But the margin for error is incredibly thin. If your
333
00:17:07.230 --> 00:17:10.670
form breaks down even slightly under a heavy load, the
334
00:17:10.759 --> 00:17:15.380
risk of a catastrophic disc injury is incredibly high. Now
335
00:17:15.440 --> 00:17:18.480
contrast that with a hex bar or a trap bar,
336
00:17:18.660 --> 00:17:19.980
which is shaped like a hexagon.
337
00:17:20.180 --> 00:17:23.269
You literally step inside the bar. You are standing right
338
00:17:23.309 --> 00:17:24.309
in the center of the weight.
339
00:17:24.569 --> 00:17:27.269
Exactly. The center of mass of the load is perfectly
340
00:17:27.329 --> 00:17:31.039
aligned with your own center of gravity. This geometry drastically
341
00:17:31.119 --> 00:17:34.190
reduces the sheer force on the lumbar spine and converts
342
00:17:34.230 --> 00:17:35.390
it into compressive force.
343
00:17:35.809 --> 00:17:38.049
Meaning the weight is just pressing straight down through the
344
00:17:38.089 --> 00:17:41.069
structural columns of your legs and spine rather than trying
345
00:17:41.109 --> 00:17:42.569
to snap you in half like a twig.
346
00:17:42.769 --> 00:17:43.230
Exactly.
347
00:17:43.289 --> 00:17:45.079
But, you know, why do we even need to lift
348
00:17:45.140 --> 00:17:47.400
heavy weight in the first place? If you're listening to
349
00:17:47.420 --> 00:17:49.220
this and the goal is just to live long, shouldn't
350
00:17:49.259 --> 00:17:51.160
we just do yoga and go for nice walks?
351
00:17:51.579 --> 00:17:56.250
Because without heavy mechanical loading, the chassis rots. Bone mineral
352
00:17:56.269 --> 00:18:00.690
density operates on a strict use-it-or-lose-it biological mandate. If you
353
00:18:00.730 --> 00:18:04.910
do not subject your axial skeleton to significant loads, osteopenia
354
00:18:04.950 --> 00:18:09.079
and osteoporosis are practically inevitable as you age. Muscle mass,
355
00:18:09.230 --> 00:18:12.980
particularly your fast twitch muscle fibers, will atrophy rapidly unless
356
00:18:13.000 --> 00:18:14.980
they are forced to fire under heavy resistance.
357
00:18:15.259 --> 00:18:17.940
So the hexbar deadlift is essentially a clinical tool to
358
00:18:18.019 --> 00:18:20.539
dose the body with the exact amount of heavy stress
359
00:18:20.579 --> 00:18:24.039
required to maintain bone density and central nervous system adaptation,
360
00:18:24.480 --> 00:18:27.980
while mathematically minimizing the risk of a spinal injury. It's
361
00:18:28.000 --> 00:18:31.400
an exercise stripped of ego and optimized purely for survival.
362
00:18:31.619 --> 00:18:34.720
It changes the entire paradigm of what a workout actually is.
363
00:18:35.500 --> 00:18:37.460
You are not going to the gym to get sweaty
364
00:18:37.559 --> 00:18:39.940
or burn calories or look good in a mirror. You
365
00:18:40.009 --> 00:18:42.480
are going to the gym to preserve the structural integrity
366
00:18:42.529 --> 00:18:45.150
of your physical architecture for a century of use.
367
00:18:45.569 --> 00:18:49.589
It's so intense. But all of this intense engineering, the
368
00:18:49.710 --> 00:18:55.150
fasting protocols, the immune-suppressing drugs, the force plate biomechanics, it
369
00:18:55.210 --> 00:18:59.109
raises a vital, almost existential question. You don't put this
370
00:18:59.170 --> 00:19:02.190
much effort into maintaining a 100-year chassis if you don't
371
00:19:02.369 --> 00:19:04.710
actually intend to take it out for a wild drive.
372
00:19:05.109 --> 00:19:08.730
Which transitions perfectly into the eclectic and often bizarre second
373
00:19:08.750 --> 00:19:11.750
half of this specific Joe Rogan conversation. I mean, you
374
00:19:11.789 --> 00:19:15.289
cannot talk about this 2018 interview without addressing the tangents.
375
00:19:15.410 --> 00:19:18.490
Oh, the tangents are legendary. When you put a hyper-analytical
376
00:19:18.529 --> 00:19:21.150
doctor and Joe Rogan in a room for three hours...
377
00:19:21.349 --> 00:19:25.680
the conversation inevitably drifts from cellular senescence into absolute madness.
378
00:19:26.380 --> 00:19:29.180
We have to talk about buoyancy, the shark taser, the
379
00:19:29.240 --> 00:19:32.279
elusive quattamundi, and the most delicious meat in the world.
380
00:19:32.559 --> 00:19:34.980
While they seem like random detours, these topics are actually
381
00:19:35.039 --> 00:19:38.880
deeply illustrative of the psychological profile required for extreme longevity.
382
00:19:39.089 --> 00:19:42.109
Let's start with buoyancy and shark tasers. Atiyah is known
383
00:19:42.170 --> 00:19:45.049
for his obsession with open water swimming, right? Having swam
384
00:19:45.069 --> 00:19:47.849
the Catalina Channel. And the physics of buoyancy becomes this
385
00:19:47.970 --> 00:19:49.289
massive point of discussion.
386
00:19:49.630 --> 00:19:52.720
Because it represents a completely different type of physical optimization.
387
00:19:53.839 --> 00:19:56.019
Swimming for 12 hours in the open ocean requires a
388
00:19:56.099 --> 00:19:58.839
deep understanding of the specific gravity of the human body.
389
00:19:59.519 --> 00:20:03.089
Muscle is denser than water. Fat is less dense. They
390
00:20:03.119 --> 00:20:05.690
discuss the drag coefficients of the body and how cold
391
00:20:05.769 --> 00:20:09.559
water exposure changes the metabolic demands of the swim. It's
392
00:20:09.579 --> 00:20:12.400
the literal application of physics to human endurance.
393
00:20:12.779 --> 00:20:14.680
And when you are swimming in the open ocean for
394
00:20:14.700 --> 00:20:17.500
that long, you aren't just fighting physics. You are sharing
395
00:20:17.559 --> 00:20:21.849
the water with apex predators, which brings up the shark taser.
396
00:20:22.230 --> 00:20:27.809
The transition from biomechanics to electronic shark deterrence is certainly abrupt,
397
00:20:28.049 --> 00:20:30.849
but it highlights a really specific approach to risk management.
398
00:20:30.970 --> 00:20:33.730
It really does. They discuss devices like the shark shield,
399
00:20:33.910 --> 00:20:37.660
which emits this three-dimensional electrical field around the swimmer. The
400
00:20:37.720 --> 00:20:41.039
science behind it is just wild. Sharks have these highly
401
00:20:41.099 --> 00:20:44.039
sensitive electroreceptors in their snouts. I think they're called the
402
00:20:44.180 --> 00:20:47.440
ampullae of Lorenzini, which they use to detect the faint
403
00:20:47.500 --> 00:20:51.990
electrical impulses of struggling prey. The taser overloads those receptors,
404
00:20:52.309 --> 00:20:55.730
causing the shark unbearable discomfort and forcing it to turn away.
405
00:20:56.069 --> 00:20:59.970
Think about the mindset here, though. You are meticulously optimizing
406
00:21:00.009 --> 00:21:03.970
your cellular biology to avoid cancer and heart disease, tracking
407
00:21:03.990 --> 00:21:07.799
your macros, fasting for days. But you are also strapping
408
00:21:07.900 --> 00:21:11.440
an electromagnetic field generator to your ankle so you can
409
00:21:11.519 --> 00:21:15.220
safely swim 20 miles in great white shark territory. It
410
00:21:15.279 --> 00:21:17.819
proves that longevity isn't about hiding in a padded room
411
00:21:17.859 --> 00:21:21.089
to avoid death. It's about mitigating risks so you can
412
00:21:21.140 --> 00:21:23.150
actually experience extreme environments.
413
00:21:23.529 --> 00:21:27.269
And speaking of extreme environments, the conversation veers into wild
414
00:21:27.390 --> 00:21:30.910
animals and exotic ecosystems. They bring up the Coatimundi.
415
00:21:31.009 --> 00:21:34.750
Which is more accurately known as the Coatimundi. It's a fascinating,
416
00:21:34.849 --> 00:21:38.569
highly adaptable mammal found in the Americas, related to the raccoon.
417
00:21:38.789 --> 00:21:42.579
Rogan obviously has a known obsession with bizarre wildlife, predators,
418
00:21:42.619 --> 00:21:45.420
and primate behavior. But the tangent into the behavior of
419
00:21:45.460 --> 00:21:49.400
the Quatimundi, its adaptability, its foraging habits, it seems random,
420
00:21:49.500 --> 00:21:52.180
but it underscores a vital trait for longevity, which is
421
00:21:52.539 --> 00:21:53.880
insatiable curiosity.
422
00:21:54.259 --> 00:21:58.599
Curiosity is, arguably, the most potent neuroprotective mechanism we have.
423
00:21:59.519 --> 00:22:02.099
Cognitive decline is one of the greatest threats to a
424
00:22:02.140 --> 00:22:05.599
long life. If you lose your mind, the health of
425
00:22:05.640 --> 00:22:11.369
your physical body is entirely irrelevant. Maintaining a vibrant, eclectic curiosity,
426
00:22:11.869 --> 00:22:14.690
whether it's about the physics of water drag, the electroreceptors
427
00:22:14.730 --> 00:22:18.069
of a shark, or the behavioral ecology of a coetamundi,
428
00:22:18.269 --> 00:22:21.640
keeps the brain plastic. It forces the formation of new
429
00:22:21.680 --> 00:22:22.380
neural pathways.
430
00:22:22.980 --> 00:22:25.079
It keeps you engaged with the world. I mean, if
431
00:22:25.140 --> 00:22:27.039
you are bored, what is the point of living an
432
00:22:27.079 --> 00:22:30.299
extra 30 years? Which brings us to the final tangent
433
00:22:30.539 --> 00:22:33.390
of the deep dive. the most delicious meat in the world.
434
00:22:33.529 --> 00:22:37.730
The absolute intersection of biology, diet, and primal human pleasure.
435
00:22:38.230 --> 00:22:41.470
They start the show talking about the ascetic, monk-like discipline
436
00:22:41.509 --> 00:22:44.190
of fasting for days and compressing your feeding windows, and
437
00:22:44.210 --> 00:22:47.710
they end it obsessing over the ultimate culinary experience. They
438
00:22:47.779 --> 00:22:51.359
delve into hunting, specifically discussing animals like the axis deer,
439
00:22:51.460 --> 00:22:54.240
which is often touted in these circles as the most nutrient-dense,
440
00:22:54.319 --> 00:22:55.460
flavorful meat available.
441
00:22:55.740 --> 00:22:59.839
It highlights a critical balance. Longevity protocols often require intense
442
00:22:59.900 --> 00:23:04.200
restriction and sacrifice. But harvesting your own food, understanding the
443
00:23:04.259 --> 00:23:07.769
biology of the animal, and experiencing the deep, visceral pleasure
444
00:23:07.809 --> 00:23:11.829
of an incredible meal, that is the reward. Health optimization
445
00:23:11.910 --> 00:23:15.789
without joy is just a clinical exercise in delaying the inevitable.
446
00:23:16.069 --> 00:23:18.470
So if we pull all these threads together, what does
447
00:23:18.519 --> 00:23:22.259
this 2018 touchstone really teach us? We traveled from the
448
00:23:22.299 --> 00:23:26.180
clinical rigidity of adiomedical PC, where the timing of nutrient
449
00:23:26.240 --> 00:23:29.940
intake is manipulated to control the biological clock, We explored
450
00:23:29.960 --> 00:23:33.400
the paradoxical edge of pharmacology, where a drug that causes
451
00:23:33.480 --> 00:23:36.579
mouth sores and suppresses your immune system might actually hold
452
00:23:36.619 --> 00:23:38.420
the key to stopping cellular aging.
453
00:23:38.799 --> 00:23:41.579
We looked at how the accelerated lifespans of dogs provide
454
00:23:41.599 --> 00:23:44.769
a window into our own mammalian decay. We analyzed the
455
00:23:44.829 --> 00:23:47.849
biomechanical engineering of the force plate treadmill and the hex
456
00:23:47.890 --> 00:23:51.009
bar deadlift, learning how to safely load our physical chassis
457
00:23:51.029 --> 00:23:52.410
to ensure it lasts a century.
458
00:23:52.789 --> 00:23:55.430
And we ventured into the wild tangents of shark tasers,
459
00:23:55.529 --> 00:23:57.869
the koa mundi, and the pursuit of the perfect male,
460
00:23:58.309 --> 00:24:01.349
proving that deep science must be fueled by a broad,
461
00:24:01.569 --> 00:24:02.990
unrelenting curiosity.
462
00:24:03.410 --> 00:24:08.190
This specific combination clinical precision paired with a ferocious appetite
463
00:24:08.230 --> 00:24:11.579
for life is really the definitive modern approach to the
464
00:24:11.640 --> 00:24:13.059
applied science of longevity.
465
00:24:13.319 --> 00:24:15.480
It is an incredible framework, but as we wrap up
466
00:24:15.519 --> 00:24:17.319
this deep dive, I want to leave you with a
467
00:24:17.440 --> 00:24:20.640
final provocative thought to ponder. It's something that builds on
468
00:24:20.660 --> 00:24:23.920
the foundation of everything we've discussed today. Let's assume the
469
00:24:23.960 --> 00:24:28.190
applied science of longevity succeeds entirely. Imagine you are 40
470
00:24:28.190 --> 00:24:33.069
years old, and due to precise MTOR inhibition, perfect biomechanical maintenance,
471
00:24:33.130 --> 00:24:36.410
and cellular repair, science can guarantee you another 80 years
472
00:24:36.470 --> 00:24:40.869
of prime, robust physical health. How does that century-long guarantee
473
00:24:41.029 --> 00:24:43.089
fundamentally change your relationship with risk?
474
00:24:43.569 --> 00:24:46.730
It is the ultimate psychological paradox of life extension.
475
00:24:47.190 --> 00:24:49.890
If you know you have 80 healthy years locked in,
476
00:24:50.289 --> 00:24:53.539
do you become vastly more adventurous? Do you climb the
477
00:24:53.579 --> 00:24:56.140
mountains and swim the channels because you know your pristine,
478
00:24:56.279 --> 00:24:59.720
optimized body can handle the physical stress? Or does the
479
00:24:59.779 --> 00:25:02.779
exact opposite happen? Do you become terrified of getting into
480
00:25:02.819 --> 00:25:04.900
a car or flying on a plane or taking a
481
00:25:04.940 --> 00:25:07.319
chance because suddenly you have so much more life to
482
00:25:07.359 --> 00:25:10.339
lose in a random accident? Does the promise of extreme
483
00:25:10.359 --> 00:25:14.009
longevity make us bolder, or does it render us hopelessly fragile?
484
00:25:14.650 --> 00:25:18.170
Think about your own physical architecture, think about your curiosity,
485
00:25:18.470 --> 00:25:20.069
and think about how you weigh the risks of the
486
00:25:20.109 --> 00:25:22.390
time you have left. Thank you for joining us on
487
00:25:22.410 --> 00:25:25.710
this deep dive. Keep questioning the consensus, stay curious about
488
00:25:25.730 --> 00:25:27.720
the world, and consider checking the sheer force on your
489
00:25:27.759 --> 00:25:30.460
lower back during your next workout. We'll catch you next time.
1
00:00:00.070 --> 00:00:04.459
You are listening to Interview Reactions and Analysis. Prepare for
2
00:00:04.500 --> 00:00:07.620
a deep dive into the most fascinating conversations.
3
00:00:08.259 --> 00:00:09.140
Here are your hosts.
4
00:00:09.619 --> 00:00:15.279
Imagine taking like a powerful immunosuppressant, a drug that was
5
00:00:15.339 --> 00:00:18.589
originally formulated to stop a patient's body from violently rejecting
6
00:00:18.629 --> 00:00:22.390
a transplanted kidney. Right. But taking it. Not because you're sick,
7
00:00:22.429 --> 00:00:24.250
but because you want to live to be, I don't know,
8
00:00:24.250 --> 00:00:27.300
120 years old. I mean, it sounds completely absurd, right,
9
00:00:27.339 --> 00:00:31.199
that the whole traditional medical consensus tells us to build
10
00:00:31.280 --> 00:00:35.020
up our defenses, to boost our immune system. Yet here
11
00:00:35.079 --> 00:00:38.880
is this philosophy advocating that we intentionally suppress those exact
12
00:00:38.950 --> 00:00:40.850
same defenses to extend our lives.
13
00:00:41.170 --> 00:00:43.969
It really does challenge the entire foundation of preventative medicine,
14
00:00:43.990 --> 00:00:46.810
doesn't it? I mean, we're so conditioned to view a
15
00:00:46.869 --> 00:00:49.890
suppressed immune system as the state of ultimate vulnerability, like
16
00:00:49.929 --> 00:00:52.969
a precursor to disease, not a shield against aging. But
17
00:00:53.229 --> 00:00:56.049
when you actually look closely at the biological mechanics of
18
00:00:56.119 --> 00:00:59.460
how we age, that vulnerability becomes the exact mechanism for longevity.
19
00:00:59.820 --> 00:01:03.539
Wow. Yeah. Welcome to the Deep Dive, everyone. Today is Saturday,
20
00:01:03.719 --> 00:01:07.000
July 11th, 2026. And we are sort of stepping into
21
00:01:07.049 --> 00:01:09.870
a time machine today to look back at a really
22
00:01:09.930 --> 00:01:14.409
specific cultural and scientific touchstone. We're looking at a multi-hour
23
00:01:14.469 --> 00:01:18.549
conversation from the Joe Rogan Experience, episode number 1108, which,
24
00:01:18.689 --> 00:01:21.010
if you can believe it, aired all the way back
25
00:01:21.129 --> 00:01:21.969
in 2018.
26
00:01:21.969 --> 00:01:24.769
And, you know, what's fascinating here is that specific year.
27
00:01:24.849 --> 00:01:29.359
It's crucial context. 2018 was this wild inflection point where
28
00:01:29.420 --> 00:01:33.180
the highly clinical, quantified approach to human longevity was just
29
00:01:33.200 --> 00:01:37.189
sort of beginning to break out of these hyper-specialized medical circles. and, well,
30
00:01:37.409 --> 00:01:38.810
into the broader public consciousness.
31
00:01:38.909 --> 00:01:41.430
Yeah, and the guest really driving that breakout was Dr.
32
00:01:41.469 --> 00:01:44.189
Peter Attia. Just to set the stage for you listening, Dr.
33
00:01:44.230 --> 00:01:46.769
Attia is the founder of Attia Medical PC. It's this
34
00:01:46.870 --> 00:01:49.730
highly specialized practice with offices in San Diego and New
35
00:01:49.750 --> 00:01:53.060
York City. And their mandate isn't treating the flu or
36
00:01:53.090 --> 00:01:56.219
managing standard chronic illnesses. Their entire clinical obsession is what
37
00:01:56.239 --> 00:01:57.980
they call the applied science of longevity.
38
00:01:58.500 --> 00:02:03.099
Exactly. And that phrase, applied science, is what separates it from, say,
39
00:02:03.459 --> 00:02:08.289
the theoretical biology happening in university labs. Adia Medical, PC,
40
00:02:08.909 --> 00:02:11.069
operates on this premise that we don't have to wait
41
00:02:11.110 --> 00:02:14.490
for some hypothetical longevity pill to drop in 50 years.
42
00:02:14.840 --> 00:02:19.099
We can manipulate cellular decay and biomechanical breakdown and metabolic
43
00:02:19.120 --> 00:02:24.840
dysfunction right now, today, using really aggressive, highly monitored interventions.
44
00:02:25.259 --> 00:02:28.919
Right. And in this 2018 conversation, Adia essentially opened the
45
00:02:28.960 --> 00:02:31.719
clinical fire hose on millions of listeners without dumbing down
46
00:02:31.759 --> 00:02:34.669
the biochemistry at all, which is wild. So our mission
47
00:02:34.689 --> 00:02:37.069
today is to extract the most critical insights from that
48
00:02:37.090 --> 00:02:39.990
massive discussion. We're going to explore the dietary architecture of
49
00:02:40.030 --> 00:02:43.830
living longer, the weird paradox of life-extending drugs, the mechanical
50
00:02:43.889 --> 00:02:46.030
engineering of the physical body, and, of course, some of
51
00:02:46.050 --> 00:02:49.050
the wild, bizarre conversational detours that happen when you sit
52
00:02:49.090 --> 00:02:50.370
down in that specific studio.
53
00:02:50.409 --> 00:02:51.469
Which are always the best parts.
54
00:02:51.610 --> 00:02:54.530
Oh, absolutely. So, okay, let's unpack this. The best place
55
00:02:54.550 --> 00:02:57.740
to start is probably where Atiyah anchors his own foundational protocols, right?
56
00:02:57.780 --> 00:03:00.900
The metabolic architecture of daily life. Specifically, the timing of
57
00:03:00.960 --> 00:03:01.439
what we eat.
58
00:03:01.800 --> 00:03:04.060
Yeah. This is where we run into a major conceptual
59
00:03:04.099 --> 00:03:07.659
collision right out of the gate. In the conversation, Adia
60
00:03:07.699 --> 00:03:12.599
draws a super rigid line between intermittent fasting and time-restricted feeding.
61
00:03:12.740 --> 00:03:14.780
Right. And I have to ask, because for you listening,
62
00:03:14.879 --> 00:03:17.319
does it really matter what we call it? Isn't fasting
63
00:03:17.379 --> 00:03:21.030
just fasting? Like if the result is just skipping breakfast
64
00:03:21.090 --> 00:03:25.210
and not eating your first meal until 1.000 p.m., the
65
00:03:25.289 --> 00:03:28.830
cells aren't looking at a dictionary, right? A caloric deficit
66
00:03:28.870 --> 00:03:29.949
is a caloric deficit.
67
00:03:30.419 --> 00:03:32.460
It's such a common assumption, and it makes sense on
68
00:03:32.479 --> 00:03:35.840
the surface. But in the applied science of longevity, confusing
69
00:03:35.860 --> 00:03:38.800
those two concepts is, well, it's like confusing a mild
70
00:03:38.840 --> 00:03:40.930
stretching routine with major orthopedic surgery.
71
00:03:41.069 --> 00:03:42.610
Wow, okay, that different.
72
00:03:42.629 --> 00:03:45.789
Yeah, they are biologically distinct interventions. Let's break down the
73
00:03:45.810 --> 00:03:50.229
mechanism of time-restricted feeding, or TRF. TRF is entirely about
74
00:03:50.289 --> 00:03:54.259
standardizing your daily eating window to align with your circadian biology.
75
00:03:54.479 --> 00:03:54.800
Okay.
76
00:03:55.099 --> 00:03:57.419
So you might be consuming a massive amount of calories,
77
00:03:57.840 --> 00:04:01.060
enough to maintain or even build muscle. But you're compressing
78
00:04:01.080 --> 00:04:04.680
that intake into, say, an eight-hour window, leaving 16 hours
79
00:04:04.719 --> 00:04:05.099
of rest.
80
00:04:05.400 --> 00:04:07.719
So it's not about starvation at all. It's just about
81
00:04:08.210 --> 00:04:09.229
the circadian clock.
82
00:04:09.310 --> 00:04:13.889
Precisely. Your metabolic machinery, I'm talking your liver, your pancreas,
83
00:04:14.409 --> 00:04:18.449
your gut microbiome, it all operates on a circadian rhythm.
84
00:04:19.009 --> 00:04:22.810
So when you practice time-restricted feeding, you are allowing hepatic
85
00:04:22.829 --> 00:04:25.939
glycogen levels, so the sugar in your liver, to deplete
86
00:04:26.040 --> 00:04:29.970
just enough to maintain insulin sensitivity. Right. And at the
87
00:04:30.009 --> 00:04:34.350
same time, you're giving the digestive tract a predictable daily
88
00:04:34.410 --> 00:04:37.410
period of downtime. It is just a chronic daily management
89
00:04:37.449 --> 00:04:38.879
tool for the biological clock.
90
00:04:39.000 --> 00:04:41.800
But then how does that differ biologically from intermittent fasting
91
00:04:41.899 --> 00:04:45.240
as Adia defines it? Because if I push that 16-hour
92
00:04:45.279 --> 00:04:48.339
window to, say, three or four days of zero calories,
93
00:04:48.680 --> 00:04:51.379
the mechanism must just be the same, just amplified, right?
94
00:04:51.399 --> 00:04:54.199
No, it isn't just an amplification. It's a total metabolic
95
00:04:54.240 --> 00:04:54.920
paradigm shift.
96
00:04:55.160 --> 00:04:55.860
Really? Yeah.
97
00:04:55.899 --> 00:04:58.000
When you push past that two- or three-day mark of
98
00:04:58.079 --> 00:05:01.930
zero caloric intake, You deplete your liver's glycogen stores completely.
99
00:05:02.569 --> 00:05:05.889
And that forces the body to undergo this profound evolutionary
100
00:05:05.930 --> 00:05:09.370
survival response. This is where you trigger deep autophagy.
101
00:05:09.470 --> 00:05:12.230
Okay, autophagy being the cellular house cleaning process.
102
00:05:12.430 --> 00:05:15.850
Yes, exactly. The literal translation is self-eating. So when the
103
00:05:15.889 --> 00:05:20.629
body detects a sustained critical lack of nutrients, specific signaling
104
00:05:20.670 --> 00:05:24.100
pathways like AMPK, they ramp up. And the cells actually
105
00:05:24.199 --> 00:05:24.959
stop divining.
106
00:05:25.120 --> 00:05:25.420
Oh, wow.
107
00:05:25.660 --> 00:05:28.699
Instead, they start scavenging their own interior environments. They break
108
00:05:28.750 --> 00:05:32.990
down misfolded proteins, dysfunctional mitochondria, all the cellular debris just
109
00:05:33.029 --> 00:05:36.569
to use it for basic energy survival. Time-restricted feeding rarely
110
00:05:36.610 --> 00:05:40.350
pushes the body into deep autophagy. It just manages daily insulin.
111
00:05:41.589 --> 00:05:44.189
Intermittent fasting, on the other hand, is a blunt force
112
00:05:44.269 --> 00:05:48.279
tool to clear out the cellular junk that literally causes aging.
113
00:05:48.600 --> 00:05:51.420
So if you're listening, think about your own schedule. If
114
00:05:51.439 --> 00:05:53.199
you are eating from the moment you wake up, having
115
00:05:53.220 --> 00:05:55.800
a snack at 10 a.m., a big lunch, dinner, and
116
00:05:55.839 --> 00:06:00.040
then a late-night snack, your body is perpetually flooded with nutrients.
117
00:06:00.120 --> 00:06:03.029
You are locked in this perpetual state of growth and storage.
118
00:06:03.269 --> 00:06:06.769
And in the context of longevity, chronic unchecked growth is
119
00:06:06.810 --> 00:06:11.310
the enemy. Constant nutrient signaling keeps a specific pathway. It's
120
00:06:11.329 --> 00:06:17.000
called MTR, permanently elevated. And when MTR is active, cells divide,
121
00:06:17.079 --> 00:06:21.220
tumors can grow. And the biological machine just prioritizes expansion
122
00:06:21.279 --> 00:06:21.819
over repair.
123
00:06:22.220 --> 00:06:25.139
Which brings us perfectly to the absolute wildest part of
124
00:06:25.160 --> 00:06:28.540
this discussion. We just established that fasting, you know, the
125
00:06:28.639 --> 00:06:33.339
literal deprivation of nutrients for days, suppresses that MTR pathway
126
00:06:33.379 --> 00:06:36.279
and forces the body to repair itself. But what if
127
00:06:36.319 --> 00:06:39.040
you could flip that genetic switch without having to starve
128
00:06:39.079 --> 00:06:39.579
for a week?
129
00:06:39.879 --> 00:06:40.759
Enter repamycin.
130
00:06:40.959 --> 00:06:44.319
Yes. This drug completely flips the script. I mean, the
131
00:06:44.439 --> 00:06:48.269
origins alone are fascinating. It's a compound originally discovered in
132
00:06:48.310 --> 00:06:51.250
the dirt, literally in the soil of Easter Island Rapa Nui,
133
00:06:51.529 --> 00:06:54.290
produced by a specific bacterium. And as we mentioned at
134
00:06:54.329 --> 00:06:56.810
the start of the show, its primary clinical application has
135
00:06:56.870 --> 00:07:00.860
been as a potent immune suppressant for organ transplant patients. Right.
136
00:07:00.899 --> 00:07:03.620
And this is exactly where the longevity paradox lies. The
137
00:07:03.680 --> 00:07:06.319
target that rapamycin binds to in the human body is
138
00:07:06.399 --> 00:07:09.259
so central to our biology that it was literally named
139
00:07:09.319 --> 00:07:12.139
after the drug. It's called the mechanistic target of rapamycin
140
00:07:12.160 --> 00:07:12.939
or MTOR.
141
00:07:13.370 --> 00:07:18.230
So the drug suppresses MTOR, which then dampens the immune system.
142
00:07:19.370 --> 00:07:20.870
But wait, this is the part I get stuck on.
143
00:07:21.290 --> 00:07:24.269
How does shutting down the immune system correlate with extending
144
00:07:24.329 --> 00:07:27.949
human life? Because we spend, I mean, billions of dollars
145
00:07:27.990 --> 00:07:31.509
globally on vitamin C and zinc and all these supplements
146
00:07:31.569 --> 00:07:33.459
trying to boost our immune systems.
147
00:07:33.699 --> 00:07:37.379
Yeah, it requires a complete reevaluation of what aging actually is.
148
00:07:37.839 --> 00:07:40.220
As we get older, our immune system doesn't just get weaker,
149
00:07:40.300 --> 00:07:44.149
it gets dysregulated. We accumulate these things called senescent cells.
150
00:07:44.389 --> 00:07:45.209
The zombie cells.
151
00:07:45.269 --> 00:07:48.209
Exactly, the zombie cells. They have stopped dividing, but they
152
00:07:48.350 --> 00:07:51.540
absolutely refuse to die. And they sit there and secrete
153
00:07:51.569 --> 00:07:55.180
this highly toxic cocktail of inflammatory cytokines.
154
00:07:55.300 --> 00:07:57.860
So they just sit in the tissue, basically polluting the
155
00:07:57.899 --> 00:07:58.939
local environment. Right.
156
00:07:59.060 --> 00:08:02.879
And your immune system, particularly these cells called macrophages, reacts
157
00:08:02.920 --> 00:08:05.339
to this toxic secretion by going into a state of
158
00:08:05.439 --> 00:08:10.329
chronic hyperactive overdrive. This constant low-grade inflammation is what actually
159
00:08:10.350 --> 00:08:14.910
drives heart disease and neurodegeneration joint decay. In the longevity space,
160
00:08:14.949 --> 00:08:16.870
it is widely referred to as inflammaging.
161
00:08:17.250 --> 00:08:18.120
Inflammaging, right.
162
00:08:18.519 --> 00:08:18.699
Okay.
163
00:08:19.259 --> 00:08:20.720
I want to try an analogy here to see if
164
00:08:20.759 --> 00:08:22.800
I have the mechanics of this right, because people always
165
00:08:22.839 --> 00:08:24.819
say it's like taking the brakes off the immune system,
166
00:08:24.920 --> 00:08:26.819
but that just never made sense to me.
167
00:08:26.860 --> 00:08:27.279
Let's hear it.
168
00:08:27.699 --> 00:08:30.149
To me, it sounds more like turning off the perimeter
169
00:08:30.189 --> 00:08:32.970
alarms at a military base. Like, as we get older,
170
00:08:32.990 --> 00:08:37.149
our immune system acts like a bunch of paranoid, sleep-deprived soldiers.
171
00:08:37.669 --> 00:08:41.039
They're shooting at shadows, throwing grenades at minor threats. And
172
00:08:41.090 --> 00:08:43.629
in the process, they are blowing up their own barracks
173
00:08:43.690 --> 00:08:48.350
and destroying the base. So rapamycin comes in, shuts off
174
00:08:48.389 --> 00:08:50.570
the blaring alarms, and tells the soldiers to put their
175
00:08:50.610 --> 00:08:53.110
weapons down and just start sweeping the floors.
176
00:08:53.490 --> 00:08:56.929
That is actually a much more accurate representation of the pharmacology.
177
00:08:56.990 --> 00:08:57.190
Yeah.
178
00:08:57.370 --> 00:09:01.009
By inhibiting MTOR with rapamycin, you are forcing the cells
179
00:09:01.070 --> 00:09:04.940
to stop their panicked hyperactive growth and secretion phases. You're
180
00:09:04.980 --> 00:09:08.899
dampening that friendly fire, which theoretically slows down the entire
181
00:09:09.000 --> 00:09:09.639
aging process.
182
00:09:10.159 --> 00:09:13.440
But there is a massive catch. And Attia, to his credit,
183
00:09:13.580 --> 00:09:15.960
doesn't shy away from it in the conversation. You can't
184
00:09:16.000 --> 00:09:19.629
just hack the MTR pathway without collateral damage. The source
185
00:09:19.649 --> 00:09:23.870
material dives into a very specific, weird side effect of rapamycin,
186
00:09:24.370 --> 00:09:25.250
aphthous ulcers.
187
00:09:25.509 --> 00:09:28.809
Which are essentially severe mouth sores or canker sores.
188
00:09:29.070 --> 00:09:31.720
Right. And I just found it so jarring that in
189
00:09:31.750 --> 00:09:35.820
this multi-hour discussion about extending human life to 120, they
190
00:09:35.840 --> 00:09:39.659
spent a significant chunk of time talking about canker sores. Like,
191
00:09:40.139 --> 00:09:44.220
Why is this hyperspecific mucosal irritation the focal point for
192
00:09:44.259 --> 00:09:45.299
a life-extending drug?
193
00:09:45.360 --> 00:09:48.169
Well, because aphthous ulcers serve as the ultimate biomarker for
194
00:09:48.190 --> 00:09:51.330
the drug's mechanism of action. Think about the mucosal lining
195
00:09:51.350 --> 00:09:54.250
of your mouth. It has one of the absolute fastest
196
00:09:54.370 --> 00:09:57.789
cellular turnover rates in the entire human body. Those cells
197
00:09:57.830 --> 00:09:59.970
are constantly, constantly dividing and replacing themselves.
198
00:10:00.360 --> 00:10:02.279
What if it's eating and talking and all that?
199
00:10:02.399 --> 00:10:05.019
Exactly. So when you introduce a drug like rapamycin, which
200
00:10:05.100 --> 00:10:09.320
fundamentally halts cellular growth and replication, those rapidly dividing cells
201
00:10:09.360 --> 00:10:11.179
in the mouth are the very first ones to suffer.
202
00:10:11.340 --> 00:10:14.240
They just can't replicate fast enough to heal the normal
203
00:10:14.279 --> 00:10:16.039
wear and tear, so the ulcers form.
204
00:10:16.179 --> 00:10:20.549
Precisely. And in the clinical setting of antiemetical, PC, The
205
00:10:20.649 --> 00:10:23.350
presence of these ulcers isn't just, you know, an annoying
206
00:10:23.429 --> 00:10:26.799
side effect. It is proof of concept. It confirms that
207
00:10:26.840 --> 00:10:30.799
the drug is actually in the system actively suppressing MTOR.
208
00:10:31.340 --> 00:10:35.659
It really represents the razor's edge of longevity pharmacology. you
209
00:10:35.720 --> 00:10:39.799
are deliberately inducing a toxic effect to achieve a long-term
210
00:10:39.919 --> 00:10:41.419
biological recalibration.
211
00:10:41.570 --> 00:10:44.789
That fundamentally changes the philosophy of what a doctor even is.
212
00:10:44.909 --> 00:10:47.509
I mean, for centuries, medicine has been entirely reactive. You
213
00:10:47.529 --> 00:10:50.090
have a bacterial infection. The doctor gives you penicillin to
214
00:10:50.129 --> 00:10:52.429
kill it. You have a ruptured appendix. The surgeon cuts
215
00:10:52.470 --> 00:10:54.830
it out. The whole goal is to return a sick
216
00:10:54.870 --> 00:10:58.690
person to baseline. But prescribing a powerful immunosuppressant to a
217
00:10:58.830 --> 00:11:03.470
perfectly healthy 40-year-old, you're using aggressive pharmacology not to fix
218
00:11:03.490 --> 00:11:07.169
the disease, but to manipulate the fundamental architecture of time.
219
00:11:07.690 --> 00:11:11.529
It is the transition from disease management to biological engineering.
220
00:11:12.389 --> 00:11:15.690
But as you can imagine, this presents a massive clinical bottleneck.
221
00:11:16.210 --> 00:11:18.889
If you are prescribing a drug to delay aging, how
222
00:11:18.909 --> 00:11:20.029
do you even measure success?
223
00:11:20.149 --> 00:11:22.350
Right, because humans live for eight decades.
224
00:11:22.590 --> 00:11:26.450
Exactly. You cannot run a standard double-blind clinical trial that
225
00:11:26.490 --> 00:11:28.440
spans a century. By the time the data comes in,
226
00:11:28.889 --> 00:11:30.220
the researchers themselves are dead.
227
00:11:30.509 --> 00:11:33.360
That is the ultimate bottleneck. And it explains why the
228
00:11:33.399 --> 00:11:37.240
conversation takes a somewhat, I don't know, sobering turn toward
229
00:11:37.259 --> 00:11:39.940
the animals sleeping at the foot of our beds. They
230
00:11:39.980 --> 00:11:44.399
spend time discussing a very specific compressed mortality model, which
231
00:11:44.480 --> 00:11:45.259
is dogs.
232
00:11:45.559 --> 00:11:48.690
Yet looking at canine aging is not just a sentimental exercise.
233
00:11:49.230 --> 00:11:51.830
It is a highly critical scientific tool in this field.
234
00:11:52.590 --> 00:11:56.629
Dogs offer a unique, accelerated window into mammalian biology.
235
00:11:56.769 --> 00:11:59.940
Because their lifespans are roughly a decade. In 12 years,
236
00:12:00.159 --> 00:12:02.539
a large breed dog goes from a newborn puppy to
237
00:12:02.580 --> 00:12:06.299
an elite athlete in its prime, straight into senior cognitive decline,
238
00:12:06.460 --> 00:12:09.570
joint failure, and terminal disease. It's incredibly fast.
239
00:12:09.990 --> 00:12:14.529
And crucially, they share our exact environment. This is key.
240
00:12:15.409 --> 00:12:18.850
Unlike a laboratory mouse kept in a sterile, temperature-controlled box
241
00:12:19.169 --> 00:12:22.629
eating highly processed pellets, dogs live in our homes.
242
00:12:23.169 --> 00:12:23.529
Right.
243
00:12:23.570 --> 00:12:26.399
They are exposed to the exact same off-gassing from our carpets,
244
00:12:26.820 --> 00:12:30.440
the same circadian disruptions from artificial lighting, the same water supply,
245
00:12:30.960 --> 00:12:33.950
and often similar psychological stressors from the household.
246
00:12:34.090 --> 00:12:38.190
They are basically running the human aging program on fast forward. Exactly.
247
00:12:38.889 --> 00:12:41.889
When an applied longevity researcher studies how a dog's joints
248
00:12:41.929 --> 00:12:45.139
degrade or how their immune system succumbs to canine cancer,
249
00:12:45.700 --> 00:12:48.799
they are observing the vulnerabilities of the mammalian chassis in
250
00:12:48.899 --> 00:12:52.580
real time. Much of the data regarding MTOR inhibition and
251
00:12:52.620 --> 00:12:56.000
rapamycin's efficacy actually stems from the Dog Aging Project.
252
00:12:56.059 --> 00:12:56.360
Really?
253
00:12:56.379 --> 00:12:58.679
Oh, yeah. Because you can administer the drug to a
254
00:12:58.720 --> 00:13:03.250
middle-aged dog and see definitive, measurable impacts on cardiac function
255
00:13:03.299 --> 00:13:05.529
and cognitive health within just two or three years.
256
00:13:05.850 --> 00:13:08.389
Wow. And, you know, while it can be heavy to
257
00:13:08.429 --> 00:13:11.789
think about the mortality of our pets, there is a
258
00:13:12.009 --> 00:13:16.360
beautiful reciprocity here. The interventions we test to understand human
259
00:13:16.480 --> 00:13:19.620
aging are simultaneously providing therapies that might give us an
260
00:13:19.659 --> 00:13:22.220
extra three or four healthy years with our dogs. It's
261
00:13:22.259 --> 00:13:25.539
this really elegant overlap of science and companionship.
262
00:13:25.779 --> 00:13:29.230
It is. But studying the biochemical decay of a dog
263
00:13:29.309 --> 00:13:32.309
or a human brings us to a really harsh reality
264
00:13:32.350 --> 00:13:36.230
in the longevity space. Cellular aging is only half the equation.
265
00:13:36.669 --> 00:13:39.809
You can have the pristine, empty, or suppressed biochemistry of
266
00:13:39.850 --> 00:13:42.889
a 30-year-old. But if your hip joint is structurally ground
267
00:13:42.929 --> 00:13:46.509
to dust, or your lumbar spine is completely collapsed, your
268
00:13:46.549 --> 00:13:48.019
health span is effectively over.
269
00:13:48.450 --> 00:13:50.769
Oh man, that is the nightmare scenario, isn't it? Living
270
00:13:50.809 --> 00:13:53.549
to 110 but spending the last three decades trapped in
271
00:13:53.590 --> 00:13:57.690
a wheelchair because your structural engineering failed? Biochemistry is absolutely
272
00:13:57.809 --> 00:13:59.149
useless without biomechanics.
273
00:13:59.250 --> 00:14:02.169
Which is why the diagnostic landscape of longevity requires a
274
00:14:02.250 --> 00:14:05.350
massive shift from the microscopic to the macroscopic. And it's
275
00:14:05.370 --> 00:14:07.809
why the tools at a clinic like Atia's seem more
276
00:14:07.889 --> 00:14:11.490
suited to an Olympic training center than a traditional doctor's office.
277
00:14:11.990 --> 00:14:14.169
Yes, let's talk about the force plate treadmill because this
278
00:14:14.210 --> 00:14:17.240
piece of equipment is fascinating. Most people think of a
279
00:14:17.269 --> 00:14:19.779
treadmill as just a moving belt to get your heart
280
00:14:19.820 --> 00:14:23.159
rate up and burn some calories. Why does an applied
281
00:14:23.220 --> 00:14:28.450
longevity physician need a highly specialized, insanely expensive force plate system?
282
00:14:28.850 --> 00:14:33.190
Because gravity is the ultimate inescapable stressor on the human body.
283
00:14:33.889 --> 00:14:36.850
A force plate treadmill doesn't just measure your cardiovascular output.
284
00:14:37.460 --> 00:14:41.740
It maps the exact ground reaction forces of every single
285
00:14:41.799 --> 00:14:42.370
foot strike.
286
00:14:42.539 --> 00:14:43.850
Okay, what does that mean in practice?
287
00:14:44.149 --> 00:14:47.549
It measures the milliseconds of contact time, the asymmetrical loading
288
00:14:47.590 --> 00:14:50.210
between your left and right leg, and the sheer force
289
00:14:50.289 --> 00:14:52.649
transmitted up through your entire kinematic chain.
290
00:14:52.809 --> 00:14:55.690
So it's diagnosing microscopic imbalances. Like, let's say you have
291
00:14:55.730 --> 00:14:58.769
a 3% discrepancy in how your right foot absorbs shock
292
00:14:58.850 --> 00:15:01.500
compared to your left. If you run 3 miles a
293
00:15:01.500 --> 00:15:05.240
day for 20 years, that tiny 3% asymmetry compounds over
294
00:15:05.419 --> 00:15:06.620
millions of repetitions.
295
00:15:07.299 --> 00:15:11.480
And it results in a catastrophic structural failure, a torn meniscus,
296
00:15:12.019 --> 00:15:16.259
a degraded hip labrum, or severe lower back trauma. The
297
00:15:16.320 --> 00:15:18.580
force plate allows a physician to look at a perfectly
298
00:15:18.620 --> 00:15:22.580
healthy 40-year-old patient and say, your biochemistry is fine, but
299
00:15:22.600 --> 00:15:24.409
the way your foot hits the ground is going to
300
00:15:24.419 --> 00:15:27.250
require a hip replacement by age 65.
301
00:15:27.250 --> 00:15:29.350
So they have to correct the movement pattern before the
302
00:15:29.370 --> 00:15:33.470
damage accrues. And this highlights a fascinating theme in Atiyah's approach.
303
00:15:34.049 --> 00:15:37.330
He talks about seeking out the guru of speed. He
304
00:15:37.529 --> 00:15:41.330
actively consults with sprint coaches and biomechanics experts who train
305
00:15:41.370 --> 00:15:42.690
the fastest humans on Earth.
306
00:15:42.970 --> 00:15:46.009
Which might seem completely counterintuitive for a longevity patient who
307
00:15:46.049 --> 00:15:48.710
just wants to play with their grandchildren, not run a
308
00:15:48.809 --> 00:15:53.570
sub-10-second 100-meter dash. But the underlying logic is profound. A
309
00:15:53.669 --> 00:15:56.950
guru of speed is a master of mechanical efficiency.
310
00:15:57.269 --> 00:16:01.629
Right, because elite sprinters cannot afford leaked energy or structural imbalances,
311
00:16:02.090 --> 00:16:04.750
or they literally tear their hamstrings to shreds on the track.
312
00:16:05.070 --> 00:16:10.159
Exactly. By studying the absolute pinnacle of human movement, longevity
313
00:16:10.299 --> 00:16:13.730
experts can reverse engineer those mechanics to teach a 50-year-old
314
00:16:13.759 --> 00:16:16.710
how to walk, run, and carry weight safely for the
315
00:16:16.750 --> 00:16:17.629
next 50 years.
316
00:16:17.950 --> 00:16:20.809
And the ultimate application of carrying weight safely brings us
317
00:16:20.850 --> 00:16:24.190
to what might be the cornerstone of physical longevity training
318
00:16:24.230 --> 00:16:28.169
and its protocols, the hex bar deadlift. If you think
319
00:16:28.210 --> 00:16:30.620
a deadlift is just picking up a heavy barbell to
320
00:16:30.669 --> 00:16:33.340
build big muscles for the beach, you are missing the
321
00:16:33.399 --> 00:16:34.679
entire architectural point.
322
00:16:35.090 --> 00:16:37.169
To really understand the hex bar, we first have to
323
00:16:37.210 --> 00:16:40.789
understand the inherent risk of the traditional straight bar deadlift.
324
00:16:41.350 --> 00:16:43.690
When you walk up to a standard barbell, the weight
325
00:16:43.730 --> 00:16:46.629
is positioned entirely in front of your shins. As you
326
00:16:46.649 --> 00:16:49.070
bend down to grip it, the lever arm between the
327
00:16:49.129 --> 00:16:51.470
weight and your lower back creates a massive amount of
328
00:16:51.529 --> 00:16:53.230
sheer force on the lumbar spine.
329
00:16:53.769 --> 00:16:57.029
Sheer force meaning the vertebrae are being pulled horizontally, trying
330
00:16:57.049 --> 00:16:58.250
to slide past one another.
331
00:16:58.509 --> 00:17:02.529
Correct. It is a phenomenal exercise for posterior chain development.
332
00:17:03.230 --> 00:17:07.109
But the margin for error is incredibly thin. If your
333
00:17:07.230 --> 00:17:10.670
form breaks down even slightly under a heavy load, the
334
00:17:10.759 --> 00:17:15.380
risk of a catastrophic disc injury is incredibly high. Now
335
00:17:15.440 --> 00:17:18.480
contrast that with a hex bar or a trap bar,
336
00:17:18.660 --> 00:17:19.980
which is shaped like a hexagon.
337
00:17:20.180 --> 00:17:23.269
You literally step inside the bar. You are standing right
338
00:17:23.309 --> 00:17:24.309
in the center of the weight.
339
00:17:24.569 --> 00:17:27.269
Exactly. The center of mass of the load is perfectly
340
00:17:27.329 --> 00:17:31.039
aligned with your own center of gravity. This geometry drastically
341
00:17:31.119 --> 00:17:34.190
reduces the sheer force on the lumbar spine and converts
342
00:17:34.230 --> 00:17:35.390
it into compressive force.
343
00:17:35.809 --> 00:17:38.049
Meaning the weight is just pressing straight down through the
344
00:17:38.089 --> 00:17:41.069
structural columns of your legs and spine rather than trying
345
00:17:41.109 --> 00:17:42.569
to snap you in half like a twig.
346
00:17:42.769 --> 00:17:43.230
Exactly.
347
00:17:43.289 --> 00:17:45.079
But, you know, why do we even need to lift
348
00:17:45.140 --> 00:17:47.400
heavy weight in the first place? If you're listening to
349
00:17:47.420 --> 00:17:49.220
this and the goal is just to live long, shouldn't
350
00:17:49.259 --> 00:17:51.160
we just do yoga and go for nice walks?
351
00:17:51.579 --> 00:17:56.250
Because without heavy mechanical loading, the chassis rots. Bone mineral
352
00:17:56.269 --> 00:18:00.690
density operates on a strict use-it-or-lose-it biological mandate. If you
353
00:18:00.730 --> 00:18:04.910
do not subject your axial skeleton to significant loads, osteopenia
354
00:18:04.950 --> 00:18:09.079
and osteoporosis are practically inevitable as you age. Muscle mass,
355
00:18:09.230 --> 00:18:12.980
particularly your fast twitch muscle fibers, will atrophy rapidly unless
356
00:18:13.000 --> 00:18:14.980
they are forced to fire under heavy resistance.
357
00:18:15.259 --> 00:18:17.940
So the hexbar deadlift is essentially a clinical tool to
358
00:18:18.019 --> 00:18:20.539
dose the body with the exact amount of heavy stress
359
00:18:20.579 --> 00:18:24.039
required to maintain bone density and central nervous system adaptation,
360
00:18:24.480 --> 00:18:27.980
while mathematically minimizing the risk of a spinal injury. It's
361
00:18:28.000 --> 00:18:31.400
an exercise stripped of ego and optimized purely for survival.
362
00:18:31.619 --> 00:18:34.720
It changes the entire paradigm of what a workout actually is.
363
00:18:35.500 --> 00:18:37.460
You are not going to the gym to get sweaty
364
00:18:37.559 --> 00:18:39.940
or burn calories or look good in a mirror. You
365
00:18:40.009 --> 00:18:42.480
are going to the gym to preserve the structural integrity
366
00:18:42.529 --> 00:18:45.150
of your physical architecture for a century of use.
367
00:18:45.569 --> 00:18:49.589
It's so intense. But all of this intense engineering, the
368
00:18:49.710 --> 00:18:55.150
fasting protocols, the immune-suppressing drugs, the force plate biomechanics, it
369
00:18:55.210 --> 00:18:59.109
raises a vital, almost existential question. You don't put this
370
00:18:59.170 --> 00:19:02.190
much effort into maintaining a 100-year chassis if you don't
371
00:19:02.369 --> 00:19:04.710
actually intend to take it out for a wild drive.
372
00:19:05.109 --> 00:19:08.730
Which transitions perfectly into the eclectic and often bizarre second
373
00:19:08.750 --> 00:19:11.750
half of this specific Joe Rogan conversation. I mean, you
374
00:19:11.789 --> 00:19:15.289
cannot talk about this 2018 interview without addressing the tangents.
375
00:19:15.410 --> 00:19:18.490
Oh, the tangents are legendary. When you put a hyper-analytical
376
00:19:18.529 --> 00:19:21.150
doctor and Joe Rogan in a room for three hours...
377
00:19:21.349 --> 00:19:25.680
the conversation inevitably drifts from cellular senescence into absolute madness.
378
00:19:26.380 --> 00:19:29.180
We have to talk about buoyancy, the shark taser, the
379
00:19:29.240 --> 00:19:32.279
elusive quattamundi, and the most delicious meat in the world.
380
00:19:32.559 --> 00:19:34.980
While they seem like random detours, these topics are actually
381
00:19:35.039 --> 00:19:38.880
deeply illustrative of the psychological profile required for extreme longevity.
382
00:19:39.089 --> 00:19:42.109
Let's start with buoyancy and shark tasers. Atiyah is known
383
00:19:42.170 --> 00:19:45.049
for his obsession with open water swimming, right? Having swam
384
00:19:45.069 --> 00:19:47.849
the Catalina Channel. And the physics of buoyancy becomes this
385
00:19:47.970 --> 00:19:49.289
massive point of discussion.
386
00:19:49.630 --> 00:19:52.720
Because it represents a completely different type of physical optimization.
387
00:19:53.839 --> 00:19:56.019
Swimming for 12 hours in the open ocean requires a
388
00:19:56.099 --> 00:19:58.839
deep understanding of the specific gravity of the human body.
389
00:19:59.519 --> 00:20:03.089
Muscle is denser than water. Fat is less dense. They
390
00:20:03.119 --> 00:20:05.690
discuss the drag coefficients of the body and how cold
391
00:20:05.769 --> 00:20:09.559
water exposure changes the metabolic demands of the swim. It's
392
00:20:09.579 --> 00:20:12.400
the literal application of physics to human endurance.
393
00:20:12.779 --> 00:20:14.680
And when you are swimming in the open ocean for
394
00:20:14.700 --> 00:20:17.500
that long, you aren't just fighting physics. You are sharing
395
00:20:17.559 --> 00:20:21.849
the water with apex predators, which brings up the shark taser.
396
00:20:22.230 --> 00:20:27.809
The transition from biomechanics to electronic shark deterrence is certainly abrupt,
397
00:20:28.049 --> 00:20:30.849
but it highlights a really specific approach to risk management.
398
00:20:30.970 --> 00:20:33.730
It really does. They discuss devices like the shark shield,
399
00:20:33.910 --> 00:20:37.660
which emits this three-dimensional electrical field around the swimmer. The
400
00:20:37.720 --> 00:20:41.039
science behind it is just wild. Sharks have these highly
401
00:20:41.099 --> 00:20:44.039
sensitive electroreceptors in their snouts. I think they're called the
402
00:20:44.180 --> 00:20:47.440
ampullae of Lorenzini, which they use to detect the faint
403
00:20:47.500 --> 00:20:51.990
electrical impulses of struggling prey. The taser overloads those receptors,
404
00:20:52.309 --> 00:20:55.730
causing the shark unbearable discomfort and forcing it to turn away.
405
00:20:56.069 --> 00:20:59.970
Think about the mindset here, though. You are meticulously optimizing
406
00:21:00.009 --> 00:21:03.970
your cellular biology to avoid cancer and heart disease, tracking
407
00:21:03.990 --> 00:21:07.799
your macros, fasting for days. But you are also strapping
408
00:21:07.900 --> 00:21:11.440
an electromagnetic field generator to your ankle so you can
409
00:21:11.519 --> 00:21:15.220
safely swim 20 miles in great white shark territory. It
410
00:21:15.279 --> 00:21:17.819
proves that longevity isn't about hiding in a padded room
411
00:21:17.859 --> 00:21:21.089
to avoid death. It's about mitigating risks so you can
412
00:21:21.140 --> 00:21:23.150
actually experience extreme environments.
413
00:21:23.529 --> 00:21:27.269
And speaking of extreme environments, the conversation veers into wild
414
00:21:27.390 --> 00:21:30.910
animals and exotic ecosystems. They bring up the Coatimundi.
415
00:21:31.009 --> 00:21:34.750
Which is more accurately known as the Coatimundi. It's a fascinating,
416
00:21:34.849 --> 00:21:38.569
highly adaptable mammal found in the Americas, related to the raccoon.
417
00:21:38.789 --> 00:21:42.579
Rogan obviously has a known obsession with bizarre wildlife, predators,
418
00:21:42.619 --> 00:21:45.420
and primate behavior. But the tangent into the behavior of
419
00:21:45.460 --> 00:21:49.400
the Quatimundi, its adaptability, its foraging habits, it seems random,
420
00:21:49.500 --> 00:21:52.180
but it underscores a vital trait for longevity, which is
421
00:21:52.539 --> 00:21:53.880
insatiable curiosity.
422
00:21:54.259 --> 00:21:58.599
Curiosity is, arguably, the most potent neuroprotective mechanism we have.
423
00:21:59.519 --> 00:22:02.099
Cognitive decline is one of the greatest threats to a
424
00:22:02.140 --> 00:22:05.599
long life. If you lose your mind, the health of
425
00:22:05.640 --> 00:22:11.369
your physical body is entirely irrelevant. Maintaining a vibrant, eclectic curiosity,
426
00:22:11.869 --> 00:22:14.690
whether it's about the physics of water drag, the electroreceptors
427
00:22:14.730 --> 00:22:18.069
of a shark, or the behavioral ecology of a coetamundi,
428
00:22:18.269 --> 00:22:21.640
keeps the brain plastic. It forces the formation of new
429
00:22:21.680 --> 00:22:22.380
neural pathways.
430
00:22:22.980 --> 00:22:25.079
It keeps you engaged with the world. I mean, if
431
00:22:25.140 --> 00:22:27.039
you are bored, what is the point of living an
432
00:22:27.079 --> 00:22:30.299
extra 30 years? Which brings us to the final tangent
433
00:22:30.539 --> 00:22:33.390
of the deep dive. the most delicious meat in the world.
434
00:22:33.529 --> 00:22:37.730
The absolute intersection of biology, diet, and primal human pleasure.
435
00:22:38.230 --> 00:22:41.470
They start the show talking about the ascetic, monk-like discipline
436
00:22:41.509 --> 00:22:44.190
of fasting for days and compressing your feeding windows, and
437
00:22:44.210 --> 00:22:47.710
they end it obsessing over the ultimate culinary experience. They
438
00:22:47.779 --> 00:22:51.359
delve into hunting, specifically discussing animals like the axis deer,
439
00:22:51.460 --> 00:22:54.240
which is often touted in these circles as the most nutrient-dense,
440
00:22:54.319 --> 00:22:55.460
flavorful meat available.
441
00:22:55.740 --> 00:22:59.839
It highlights a critical balance. Longevity protocols often require intense
442
00:22:59.900 --> 00:23:04.200
restriction and sacrifice. But harvesting your own food, understanding the
443
00:23:04.259 --> 00:23:07.769
biology of the animal, and experiencing the deep, visceral pleasure
444
00:23:07.809 --> 00:23:11.829
of an incredible meal, that is the reward. Health optimization
445
00:23:11.910 --> 00:23:15.789
without joy is just a clinical exercise in delaying the inevitable.
446
00:23:16.069 --> 00:23:18.470
So if we pull all these threads together, what does
447
00:23:18.519 --> 00:23:22.259
this 2018 touchstone really teach us? We traveled from the
448
00:23:22.299 --> 00:23:26.180
clinical rigidity of adiomedical PC, where the timing of nutrient
449
00:23:26.240 --> 00:23:29.940
intake is manipulated to control the biological clock, We explored
450
00:23:29.960 --> 00:23:33.400
the paradoxical edge of pharmacology, where a drug that causes
451
00:23:33.480 --> 00:23:36.579
mouth sores and suppresses your immune system might actually hold
452
00:23:36.619 --> 00:23:38.420
the key to stopping cellular aging.
453
00:23:38.799 --> 00:23:41.579
We looked at how the accelerated lifespans of dogs provide
454
00:23:41.599 --> 00:23:44.769
a window into our own mammalian decay. We analyzed the
455
00:23:44.829 --> 00:23:47.849
biomechanical engineering of the force plate treadmill and the hex
456
00:23:47.890 --> 00:23:51.009
bar deadlift, learning how to safely load our physical chassis
457
00:23:51.029 --> 00:23:52.410
to ensure it lasts a century.
458
00:23:52.789 --> 00:23:55.430
And we ventured into the wild tangents of shark tasers,
459
00:23:55.529 --> 00:23:57.869
the koa mundi, and the pursuit of the perfect male,
460
00:23:58.309 --> 00:24:01.349
proving that deep science must be fueled by a broad,
461
00:24:01.569 --> 00:24:02.990
unrelenting curiosity.
462
00:24:03.410 --> 00:24:08.190
This specific combination clinical precision paired with a ferocious appetite
463
00:24:08.230 --> 00:24:11.579
for life is really the definitive modern approach to the
464
00:24:11.640 --> 00:24:13.059
applied science of longevity.
465
00:24:13.319 --> 00:24:15.480
It is an incredible framework, but as we wrap up
466
00:24:15.519 --> 00:24:17.319
this deep dive, I want to leave you with a
467
00:24:17.440 --> 00:24:20.640
final provocative thought to ponder. It's something that builds on
468
00:24:20.660 --> 00:24:23.920
the foundation of everything we've discussed today. Let's assume the
469
00:24:23.960 --> 00:24:28.190
applied science of longevity succeeds entirely. Imagine you are 40
470
00:24:28.190 --> 00:24:33.069
years old, and due to precise MTOR inhibition, perfect biomechanical maintenance,
471
00:24:33.130 --> 00:24:36.410
and cellular repair, science can guarantee you another 80 years
472
00:24:36.470 --> 00:24:40.869
of prime, robust physical health. How does that century-long guarantee
473
00:24:41.029 --> 00:24:43.089
fundamentally change your relationship with risk?
474
00:24:43.569 --> 00:24:46.730
It is the ultimate psychological paradox of life extension.
475
00:24:47.190 --> 00:24:49.890
If you know you have 80 healthy years locked in,
476
00:24:50.289 --> 00:24:53.539
do you become vastly more adventurous? Do you climb the
477
00:24:53.579 --> 00:24:56.140
mountains and swim the channels because you know your pristine,
478
00:24:56.279 --> 00:24:59.720
optimized body can handle the physical stress? Or does the
479
00:24:59.779 --> 00:25:02.779
exact opposite happen? Do you become terrified of getting into
480
00:25:02.819 --> 00:25:04.900
a car or flying on a plane or taking a
481
00:25:04.940 --> 00:25:07.319
chance because suddenly you have so much more life to
482
00:25:07.359 --> 00:25:10.339
lose in a random accident? Does the promise of extreme
483
00:25:10.359 --> 00:25:14.009
longevity make us bolder, or does it render us hopelessly fragile?
484
00:25:14.650 --> 00:25:18.170
Think about your own physical architecture, think about your curiosity,
485
00:25:18.470 --> 00:25:20.069
and think about how you weigh the risks of the
486
00:25:20.109 --> 00:25:22.390
time you have left. Thank you for joining us on
487
00:25:22.410 --> 00:25:25.710
this deep dive. Keep questioning the consensus, stay curious about
488
00:25:25.730 --> 00:25:27.720
the world, and consider checking the sheer force on your
489
00:25:27.759 --> 00:25:30.460
lower back during your next workout. We'll catch you next time.
