Dr. Gabrielle Lyon has spent her career making the case that skeletal muscle, not fat, deserves to be at the center of how we think about long-term health. She joined Sean Kelly on the Digital Social Hour to talk through the ideas behind her book and her broader push to reframe how people approach nutrition and aging.
The conversation covers her clinical perspective on protein, muscle health, and where she believes conventional dietary guidance falls short — offered throughout as her own medical viewpoint rather than settled consensus.
