Bret Scher, MD

Medical Director, Metabolic Mind and Baszucki Group

Bret is the host of the Metabolic Mind YouTube channel and podcast. He is a board-certified cardiologist, lipidologist, and leading expert in therapeutic uses of metabolic therapies, including ketogenic diets. Prior to joining Baszucki Group, Bret was the medical director at DietDoctor.com, an online platform promoting improving metabolic health through low-carb nutrition, where he was a content creator and medical reviewer. Earlier in his career, he worked as a cardiologist in San Diego. Bret has spent most of his 20-year career as a preventive cardiologist, helping people improve their metabolic health and preventing heart disease using low-carb nutrition and lifestyle interventions. His deep passion for educating the public about the benefits of metabolic therapies grew from his experience with the prevailing medical teaching, which frequently misrepresents nutrition science and undervalues metabolic health. Bret received an MD from The Ohio State University College of Medicine and a BS in Biology from Stanford University. He grew up in San Diego and began competing in triathlons at an early age, which helped fuel his love of health and fitness. He continues to enjoy spending time outdoors mountain biking, swimming, hiking, and playing baseball with his two boys.

Key Highlights

  • Dr. Bret Scher explains that LDL can rise sharply on a medical ketogenic diet, but that response needs to be interpreted in context with triglycerides, HDL, blood sugar, insulin, inflammation, body composition, and overall cardiovascular risk rather than in isolation.
  • He notes that some people may benefit from watching LDL trends over time before starting treatment, since cholesterol can rise early in ketosis and later level out, but he emphasizes that elevated LDL should not be ignored and should be discussed with a clinician.
  • The episode challenges the idea that ketosis harms the liver or kidneys, pointing out that human studies generally show the opposite, with ketogenic diets often improving fatty liver, blood sugar control, and markers of kidney health rather than damaging organs.
  • Dr. Scher says nuts can fit well into a ketogenic diet because they provide healthy fats and can be a useful snack, but warns that they are easy to overeat and should be considered in the context of total calories, carbs, and an individual’s goals.
  • He explains that a “good” keto diet usually emphasizes whole foods, natural fats, and nutrient-dense meals, while heavy reliance on processed keto products, frequent snacking, and daily sugary treats like regular ice cream can make it much harder to stay in ketosis and support long-term health.
