Semaglutide and Exercise Synergy in Obesity: Preserving Muscle Mass and Uncovering Organ Crosstalk.

This mouse study found semaglutide reduced both fat and lean mass, and that adding exercise partially preserved muscle while improving metabolic and vascular outcomes. Semaglutide is a genuine subject and the lean-mass finding is a relevant caveat for the drug class. Evidence is preclinical, so conclusions should not be extrapolated directly to people.
