In this episode of SHE MD Podcast, Dr. Thaïs Aliabadi and Mary Alice Haney welcome Dr. Gabrielle Lyon to explore the critical role of muscle, protein, and metabolic health in women’s longevity. Dr. Lyon challenges conventional narratives around aging and reframes strength as a foundation for long-term health, independence, and resilience.

The conversation dives into why muscle is far more than an aesthetic goal and how it supports hormonal balance, metabolic health, and functional longevity. Dr. Lyon explains how prioritizing strength can help women protect their health as they age, reduce disease risk, and maintain vitality across every stage of life. Listeners gain clarity on how protein intake, resistance training, and proactive health strategies work together to build resilience. Dr. Lyon emphasizes that the ultimate goal is not simply muscle growth, but creating stronger, more capable humans who can thrive physically, mentally, and emotionally.

This episode empowers women to rethink aging, move away from reactive healthcare, and adopt a proactive approach to strength and longevity. By focusing on function, resilience, and long-term health, Dr. Lyon offers a powerful framework for women to invest in their future selves and redefine what healthy aging truly looks like.
