GLP-1 receptor agonists exert direct anabolic and protective effects on skeletal muscle tissue, including promoting myogenesis, enhancing mitochondrial function, and reducing inflammation, which may help preserve muscle quality despite lean mass loss.
The drug may actively help protect muscle quality at a cellular level, but this does not guarantee muscle mass preservation without active lifestyle interventions.
ModerateSupportsMEDIUM confidence
Collectively, these data suggest that GLP-1RAs support skeletal muscle health through systemic fat reduction, direct pro-myogenic signalling, and metabolic reprogramming that enhances mitochondrial efficiency and contractile capacity.
Why this rating
Based on preclinical models (murine and cell culture), which may not fully translate to humans.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
