Do GLP-1s Lead to Muscle Loss? Scientists Just Made a New Discovery About How the Meds Impact Strength
Yahoo Health reports on a small study in Cell Reports Medicine of 10 men taking semaglutide for 12 weeks: thigh muscles shrank slightly, while grip strength and knee-extension strength stayed the same. Experts explain that earlier trials measured lean body mass, which includes organs and water, not muscle alone. The study author notes that no women were included and that larger, longer studies are needed.
Why it matters: Relevant to adults considering or using GLP-1 medications for weight loss, and to the clinicians who track muscle and strength in these patients.
