00:00:00.560 --> 00:00:02.759
Welcome back everybody. So today we're going to be looking
2
00:00:02.759 --> 00:00:06.480
at a major change in the BMI and how it's
3
00:00:06.519 --> 00:00:08.880
being used. I'm sure if you stepped in the doctor's
4
00:00:08.919 --> 00:00:12.039
office for the last forty years, you've been acquainted with
5
00:00:12.080 --> 00:00:16.800
the BMI. It's your weadon kilogram is divided by heightened
6
00:00:16.800 --> 00:00:20.600
meters squared That instantly categorizes you into a neat little box.
7
00:00:21.480 --> 00:00:23.839
It was quick and standard, but a growing body of
8
00:00:23.839 --> 00:00:28.320
clinical research, including landmark consensus statements published in LANs and
9
00:00:28.320 --> 00:00:30.879
as JAMA, is confirming that many researchers have argued for
10
00:00:31.000 --> 00:00:36.240
years BMI is deeply flawed. Today, medical organizations worldwide are
11
00:00:36.280 --> 00:00:38.920
executing a major pivot. They aren't throwing the metric out,
12
00:00:39.039 --> 00:00:41.960
but they are demoting it. So now the shift is
13
00:00:42.000 --> 00:00:44.399
going to waste to hip and waste to height ratios.
14
00:00:46.119 --> 00:00:49.200
Let's understand first, the flaw of the BMI treats every
15
00:00:49.200 --> 00:00:52.240
pound of human tissue is identical, and that's where the
16
00:00:52.280 --> 00:00:55.200
problem lies. A pound of muscle and pound of fat
17
00:00:55.240 --> 00:00:57.240
into the skin and a pound of visceral fat around
18
00:00:57.240 --> 00:00:59.880
the organs are all score exactly the same on the BMI,
19
00:01:00.039 --> 00:01:03.799
and this creates two massive clinical blind spots. First, it
20
00:01:03.799 --> 00:01:08.560
can mislabel muscular athletic individuals overweight, and second, and more dangerous,
21
00:01:08.599 --> 00:01:11.719
it completely misses what clinicians call normal weight obesity. These
22
00:01:11.719 --> 00:01:14.400
are individuals who BMI falls right in the green zone,
23
00:01:14.799 --> 00:01:18.120
but carry significant amounts of deep intro abdominal fat, and
24
00:01:18.159 --> 00:01:21.560
that brings us to the core issue. Location matters more
25
00:01:22.000 --> 00:01:24.719
than mass. Not all fat in the body behaves the
26
00:01:24.760 --> 00:01:28.640
same way. Subcontaneous fat, the soft layer right under your skin,
27
00:01:28.799 --> 00:01:33.040
on your legs or arms, is relatively benign. Visceral fat,
28
00:01:33.079 --> 00:01:37.879
on the other hand, wrapped around your liver, pancreas, intestines,
29
00:01:37.920 --> 00:01:40.959
it's just not an energy storage depot. It acts like
30
00:01:40.959 --> 00:01:45.920
an active endocrine organ, secreting inflammatory cytokines, promoting insulin resistance,
31
00:01:45.920 --> 00:01:51.439
and driving up cardiovascular disease. BMI doesn't tell a doctor
32
00:01:51.439 --> 00:01:54.799
where your fat store is, but the measure tape measure
33
00:01:54.840 --> 00:01:58.040
does so enter the gold standards now of waste to
34
00:01:58.120 --> 00:02:01.359
hip and waste to height. Waste to hip we'll look
35
00:02:01.400 --> 00:02:03.599
at that one first by dividing a waste circumference at
36
00:02:03.599 --> 00:02:06.359
as narrow as point by the widest point of your hips,
37
00:02:06.920 --> 00:02:10.840
So the WHR measures body shaped GMIT geometry. Distinguishing between
38
00:02:10.879 --> 00:02:15.599
apple shaped central adipacity and pair shaped lower body storage.
39
00:02:16.120 --> 00:02:19.919
Large scale population studies show that a higher WHR is
40
00:02:19.960 --> 00:02:24.240
significantly more predictive of all cause mortality, stroke, and type
41
00:02:24.240 --> 00:02:28.919
two diabetes than VMI alone. The other one, which is
42
00:02:28.919 --> 00:02:31.039
a little easier to measure, is waste to height ratio,
43
00:02:31.120 --> 00:02:34.360
which is gaining massive traction just for its simplicity. The
44
00:02:34.439 --> 00:02:38.159
clinical guideline here is remarkably straightforward. Keep your waiste circumference
45
00:02:38.240 --> 00:02:41.639
to less than half your height, so a ratio below
46
00:02:41.719 --> 00:02:44.960
a half indicates or zero point five lower metabolic risk,
47
00:02:45.039 --> 00:02:49.000
regardless of ethnic background, age, or muscle mass. In fact,
48
00:02:49.159 --> 00:02:51.840
major institutions, including the US military, of update of their
49
00:02:51.840 --> 00:02:56.840
physical Readiness and BODYCLMP protocols to incorporate waste too high. So,
50
00:02:57.000 --> 00:02:59.879
for instance, if you're six feet at seventy two inches,
51
00:03:00.680 --> 00:03:04.639
your waist should be less than thirty six inches, pretty easy, peasy.
52
00:03:04.840 --> 00:03:07.879
If you're five feet at sixty inches, you should be
53
00:03:07.960 --> 00:03:11.439
less than a thirty inch waist. Does that mean the
54
00:03:11.479 --> 00:03:13.919
BMI is dead? Well not yet. It's still quite a
55
00:03:14.000 --> 00:03:17.159
useful tool for tracking high level population statistics, but as
56
00:03:17.159 --> 00:03:20.800
an individual diagnostic tool, its rain is coming to an end.
57
00:03:21.400 --> 00:03:24.199
The future of preventative health isn't about arbitrary numbers on
58
00:03:24.240 --> 00:03:27.840
a bathroom scale. It's about metabolic health fact distribution, understanding
59
00:03:27.879 --> 00:03:30.439
what's actually happening underneath the surface.
