Optimizing Plant-Based Diet with Supplements

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 conditions such as epilepsy, bipolar disorder, diabetes and inflammatory diseases. Regardless of their reasoning for adopting this eating pattern, a key question remains: is there ever an instance where having high LDL cholesterol levels on a ketogenic diet can be safe? In Episode #311, I’m joined by Dr William Cromwell, MD and Dave Feldman to explore this question.

In this discussion, Dr William Cromwell and Dave Feldman share their professional opinions on whether high cholesterol on a keto diet is a problem. We investigate where their opinions align and where they differ, where Dave’s hypotheses diverge from the norm, and what we do and don’t know with the available evidence. We also explore the significance of ApoB, lifespan and healthspan considerations, research Dave is currently conducting, and much more.
