GLP-1 Weight Loss Requires Muscle, Protein, and Strength Training
Dr Gabrielle Lyon, Ben Greenfield and healthcare entrepreneur Brigham Buhler argue that longevity medicine should begin with physical capacity—muscle, cardiovascular fitness, protein intake and mobility—rather than experimental interventions. They regard GLP-1 drugs, hormone replacement, peptides, stem cells and plasmapheresis as potentially useful but distinct tools whose evidence, product quality, dosing and oversight require more careful judgment. Their central concern is that medicine not reduce health to weight loss, a lab threshold or access to the newest treatment.
