Some people follow a ketogenic diet seeking to lose weight, feel more energised, or gain control over their eating habits. Others may turn to this diet in an effort to treat their epilepsy, bipolar disorder, or diabetes. Regardless of their reasoning for adopting this eating pattern, a key question remains: can high LDL cholesterol levels on a ketogenic diet be safe? In Episode #311, I’m joined by Dr William Cromwell, MD and Dave Feldman to explore this question.

Dr William Cromwell is a lipidologist with over 35 years of clinical practice experience. Since 1990, Dr Cromwell’s practice has specialised in managing lipid and lipoprotein disorders. He has authored over two dozen peer-reviewed papers and book chapters on evaluating and managing lipoprotein disorders and lipoprotein analytics. Dave Feldman is a software and platform engineer, an entrepreneur, and founder of the Citizen Science Foundation. His life took a radical turn on seeing his cholesterol skyrocket after adopting a ketogenic diet, leading him to research lipidology. Through a series of self-experiments and partnering with formal researchers, he has since published the "Lipid Energy Model" which may explain this phenomenon.
