In this conversation with Dr. Gabrielle Lyon, we explore how muscle-derived signals (myokines), exercise, and cardiorespiratory fitness relate to brain metabolism, NAD biology, and long-term cognitive health, including what current evidence suggests about Alzheimer’s disease risk. We discuss why exercise appears indispensable for preserving brain function, how skeletal muscle acts as a central regulator of glucose handling and insulin sensitivity, and why muscle quality may matter more than weight loss alone. The episode also examines emerging and under-discussed data on statins, muscle function, mitochondrial biology, and metabolic hormones such as GLP-1. Finally, we broaden the discussion to precision medicine and nutrition, including limitations of one-size-fits-all dietary guidelines, biomarker-driven decision making, and why skeletal muscle remains an underappreciated organ system in modern medicine.
