In this episode, nutrition expert Dr. Donald Layman and host Dr. Gabrielle Lyon explore how protein intake affects aging, muscle maintenance, and overall metabolic health. Layman explains why not just the amount of protein, but when and how it’s distributed across meals, influences muscle protein synthesis—especially important as people age. They discuss how the body responds to fasting, why high-quality protein sources matter, and how resistance exercise works together with protein to slow age-related muscle loss. Practical insights are offered on optimizing meal timing and composition to support lean body mass, metabolic function, and long-term health.
