In this episode of Beyond Healthspan, our clinical research team explores one of the most foundational—and often misunderstood—pillars of healthy aging: protein.
Drawing from decades of research in metabolism and geroscience, Dr. Jim Lanzillotta, Dr. Rich LaFountain, and Brandon Fell unpack how dietary protein shapes muscle physiology, metabolic health, and longevity itself. From the evolving science on optimal intake to the molecular mechanisms that connect amino acid availability with mTOR signaling, insulin sensitivity, and mitochondrial function, the discussion bridges fundamental biochemistry with real-world application.
Together, they examine what current evidence reveals about the protein gap in modern diets, how resistance training and nutrient timing modulate muscle preservation across the lifespan, and why personalized protein targets—based on adjusted body weight and metabolic context—may be critical for extending both lifespan and healthspan.
