Main text
Glucagon-like peptide-1 receptor (GLP-1R) agonists, such as semaglutide, represent a significant breakthrough in pharmacological interventions to treat obesity. Meanwhile, there have been recent concerns that GLP-1R agonist treatment leads to a loss of lean mass, potentially compromising physical functions and quality of life, particularly in those susceptible to sarcopenia. In the STEP-1 trial of semaglutide, lean mass was reduced by 6.92 kg with a weight reduction of 15.3 kg, indicating that
