S2 EPISODE 49 - Low-Carb Diets and Cholesterol, LDL-C & Heart Disease Risk w/ Dr. David Diamond PhD

Season 2 Episode 49, Dr. Bubbs interviews expert Dr. David Diamond PhD to talk about cholesterol, LDL-cholesterol, saturated fats and heart disease risk. In this episode, David reviews the history of our modern fear of cholesterol, statistical misrepresentation in the early research on cholesterol and heart disease risk, and whether he believes the evidence supports saturated fat as a risk factor for heart disease. David also discusses the original research on statins, reviews the literature on LDL-c, and how much they actually impact heart disease risk. As well, David highlights the importance of LDL particle number and the fundamental role of clotting in the pathogenesis of atherosclerosis.
