Can heart disease really be reversed through autophagy, or is that going too far? In this video, Dr. Eric Westman reacts to Dr. Annette Bosworth’s explanation of reversing heart disease with keto, fasting, sardine fasts, ketones, and autophagy. This discussion covers what heart disease actually means, how coronary artery disease develops, why blood sugar and blood pressure matter, what plaque and calcium scores really tell you, and whether lowering carbs can help improve the underlying process. Dr. Westman also breaks down the theory behind the glucose-ketone ratio, the “Dr. Boz ratio,” and the idea that lower glucose and higher ketones may reflect a more favorable metabolic state. He explains where the theory is interesting, where the enthusiasm is understandable, and where the actual evidence is still limited, especially when it comes to directly measuring autophagy in humans. The video also explores keto adaptation, eating windows, earlier meal timing, sauna use, sardine fasts, water fasting, and whether these strategies truly increase autophagy or simply correlate with metabolic changes. Most importantly, Dr. Westman explains what can actually be measured right now, including triglycerides, HDL, blood pressure, blood sugar, calcium scores, and direct imaging of atherosclerosis. If you’ve heard bold claims about reversing heart disease with fasting or autophagy, this video gives a more grounded look at what the science supports, what remains theoretical, and how low-carb and ketogenic strategies fit into the bigger picture. #Autophagy #HeartDisease #DrBoz #DrEricWestman #Keto #Fasting #LowCarb #CoronaryArteryDisease #SardineFast #MetabolicHealth
