GLP-1 Weight-Loss Drugs: Muscle Loss Should Be Monitored, Not Feared
Experts say GLP-1 obesity drugs can cause some lean-mass loss during weight reduction, but the exact extent and impact on function are unclear; most weight lost remains fat and, importantly, clinical trials show improved physical function. The emphasis is on maintaining strength via adequate protein and resistance training, while avoiding marketing hype around “muscle loss.” For older adults or those with limited mobility, careful planning is advised, but the overall health benefits of GLP-1 medications often outweigh the risks.
