Episode notes
Muscle As The Central Organ For Health
- Skeletal muscle is essential for health and longevity and must be prioritized over focusing solely on body fat.
- Dr. Gabrielle Lyon states there is no way to be healthy without skeletal muscle mass.
Daily Protein Target For Muscle
- Aim for roughly one gram of protein per pound of ideal body weight daily to support muscle and repair.
- Increasing protein above standard RDA has no harmful effects for healthy people and supports better body composition.
Protect Muscle During Perimenopause
- Perimenopause accelerates muscle loss and shifts fat centrally, so increase protein intake and resistance training.
- Combine dietary protein, effective training, and consider hormonal therapy if clinically appropriate to prevent sarcopenic obesity.
