Muscle Is the Key to Longevity (Not Fat Loss) | Dr. Gabrielle Lyon | The Dr. Hyman Show

The podcast centers on muscle-centric medicine, emphasizing the critical role of skeletal muscle as the organ of longevity. Dr. Gabrielle Lyon, a physician specializing in nutritional sciences, geriatrics, and metabolism, discusses with Dr. Hyman how muscle health is often overlooked in conventional medicine, leading to conditions like sarcopenia. They explore the concept of "under-muscling" rather than "over-fat," highlighting that dysfunctional muscle is a primary driver of metabolic diseases, including cardiovascular issues and type 2 diabetes. Dr. Lyon stresses the importance of resistance training and adequate protein intake, especially as people age, to maintain muscle quality and overall health. The discussion also covers the benefits of myokines released during muscle contraction and the potential of urolithin A in promoting mitochondrial health.
