Episode notes
Prioritise Training Over Diet Alone
- Prioritize resistance training; Lyon estimates training drives ~75% of muscle outcomes.
- Combine training with sufficient dietary protein to enable repair and growth.
GLP‑1s Could Trigger Sarcopenia Wave
- GLP-1 drugs cause rapid weight loss that can include substantial muscle loss if unopposed.
- Widespread use risks shifting an obesity epidemic into a sarcopenia epidemic without muscle-focused care.
Prioritise Protein When Calories Fall
- If reducing calories (or using GLP‑1s), make protein a non‑negotiable priority.
- Combine dietary protein with resistance training to preserve muscle mass.
