Is it true that Ozempic causes loss of lean muscle mass during weight loss?
Yes. A Cleveland Clinic page states that rapid weight loss from Ozempic can decrease overall muscle mass, and a mouse study found semaglutide caused significant muscle mass loss. Other sources confirm lean mass loss occurs but debate whether it is disproportionate.
