This Study Shocks Cardiologists: LDL and ApoB May Not Predict Heart Disease Risk in Healthy People with Dr. Nick Norwitz

This episode is brought to you by LMNT and Lumebox. 

The mainstream narrative around LDL cholesterol has long claimed that high LDL is always harmful—no matter the individual or their overall health status. The traditional view holds that elevated LDL levels directly increase the risk of cardiovascular disease, regardless of metabolic health. Today’s guest, Dr. Nick Norwitz, shares groundbreaking research that further explains why plaque buildup progresses and how it can lead to heart disease. 

Today on The Dhru Purohit Show, Dhru sits down with Dr. Nick Norwitz to explore a groundbreaking study on LDL cholesterol and its implications for cardiovascular health. Dr. Norwitz dives into the role of diet, individual risk factors, and the significance of plaque progression while also addressing lifestyle influences and practical strategies for heart health. He also shares insights on the limitations of current testing methods, the impact of microplastics on cardiovascular health, and the growing gut health crisis. Dhru and Dr. Norwtiz emphasized the need for personalized nutrition, informed decision-making, and a balanced perspective between scientific research and real-world experience.

Dr. Nick Norwitz is a researcher, educator, and passionate advocate for metabolic health whose mission is to “Make Metabolic Health Mainstream.” He earned a PhD in Metabolism from the University of Oxford and is now completing his MD at Harvard Medical School. Nick’s drive in this field stems from his personal battle with severe Inflammatory Bowel Disease, which he overcame through a ketogenic diet after conventional treatments failed. His journey has fueled a deep commitment to challenging outdated thinking around health, and he’s known for his infectious curiosity and dedication to teaching.
