123: What is Metabolic Dysfunction and Why is it Killing Americans
Dr. Robert Lustig joins Buck to discuss the alarming state of metabolic health in America, where only 7% of the population is considered metabolically healthy. He breaks down metabolic dysfunction, linking it primarily to mitochondrial inefficiency, and explains how sugar—especially fructose—plays a major role in various health issues. The conversation explores the dangers of ultra-processed foods, identifying key contributors to metabolic dysfunction, including excessive sugar, insufficient fiber, and emulsifiers in processed foods. Dr. Lustig also examines the impact of hyperinsulinemia, the effects of fructose on liver health, and the role of branched-chain amino acids in metabolism. Beyond diet, he highlights the importance of understanding how insulin, amino acids, and mitochondrial function influence overall metabolic health. The discussion touches on inflammation, the challenges of making healthy choices in grocery stores, and the pros and cons of different diets, including ketogenic and carnivore diets. Lustig also underscores the significance of fasting insulin as a key marker of metabolic dysfunction and explores how nutraceuticals can support mitochondrial health.
