Episode notes
Betsy's Story
- Dr. Gabrielle Lyon's research was transformed by Betsy, a woman whose brain showed early Alzheimer's-like changes despite following conventional weight loss advice.
- This led Lyon to realize the focus should be on muscle health, not just obesity.
Muscle's Importance
- Muscle is our metabolic currency, the primary site for glucose uptake, and a major player in metabolic health.
- It also produces myokines, which impact brain health and immune function, and serves as an amino acid reservoir.
Muscle vs. Fat
- Loss of healthy muscle is more dangerous than gaining body fat due to metabolic and survivability implications.
- Healthy muscle improves mitochondrial function, glycogen storage, and overall resilience against diseases.
