What if the key to longevity isn’t found in your heart, your brain, or your hormones — but in your muscle?

In this episode of The Ready State Podcast, Dr. Gabrielle Lyon explains why skeletal muscle is the most overlooked organ in modern medicine and how its decline quietly drives aging, disease, and loss of independence. Drawing from her work in nutrition, geriatrics, and muscle-centric medicine, Lyon breaks down how strength training, protein intake, and daily movement protect metabolic health, resilience, and mental clarity as we age. From preventing sarcopenia to rethinking weight loss, GLP-1 drugs, and what it really means to age well, this conversation offers practical insights for anyone who wants to stay strong, capable, and useful for life. If you care about longevity, this episode reframes the conversation — starting with muscle!
