A ketogenic diet can dramatically improve metabolic health while sending LDL-C through the roof. So what's actually happening? Dr. Josh Wageman and Dr. Laura Buchanan break down their new study, "Increased LDL-C reduction with ezetimibe in ketogenic diet-induced hypercholesterolemia." The results raise some fascinating questions. In 14 patients who developed very high LDL-C while following a ketogenic diet, ezetimibe cut median LDL-C from 254 to 127 mg/dL—a remarkable 53% reduction. Why was the response so much greater than what's typically seen with ezetimibe? Could altered cholesterol absorption help explain why some people experience dramatic LDL increases on keto? Josh Wageman, Matt Calkins, and Laura Buchanan take us inside the study, explore the biology behind the findings, discuss what the results can—and cannot—tell us about cardiovascular risk, and explain why much more research is needed. If you've ever wondered why LDL can rise so dramatically on a ketogenic diet—and what might be driving it—this is a conversation you won't want to miss. In this episode, Dr. Tro, Dr. Buchanan, Dr. Calkins, and Dr. Wageman talk about… (00:00) Intro
