Introduction

The key to longevity, energy, and metabolic health isn't found in your heart, liver, or brain…but in your muscles. Amazingly, your muscles make up the largest organ system in your body and, importantly, the primary home of your mitochondria.

Dr. Gabrielle Lyon is a fellowship-trained physician in nutritional science and geriatrics who is revolutionizing our understanding of muscle as the organ of longevity. Her work reveals why skeletal muscle is the only organ system we have direct control over.

In this conversation, she explains the shocking 400% difference in mitochondrial capacity between athletes and people with metabolic syndrome, why the "healthy sedentary" person doesn't exist, and her proven protocol for eating and training to optimize both muscle and mitochondrial health.
