GLP-1 and Muscle Health: Meta-Analysis of Preservation Strategies
What works for preserving muscle on GLP-1 therapy? This meta-analysis reviews the evidence for various intervention strategies.
Interventions Studied
The meta-analysis reviewed 12 studies that specifically investigated muscle preservation strategies in patients on GLP-1 receptor agonists. Interventions included resistance training protocols, protein supplementation, creatine monohydrate, beta-hydroxy beta-methylbutyrate (HMB), and combination approaches.
Resistance training emerged as the single most effective intervention, preserving approximately 60-80% of the lean mass that would otherwise be lost during GLP-1 therapy.
Protein Requirements
Patients on GLP-1 therapy may need higher protein intake than standard recommendations due to reduced appetite and the catabolic effects of rapid weight loss. The meta-analysis suggests 1.2-1.6 g/kg/day of high-quality protein, distributed across 3-4 meals, as optimal for muscle preservation. Whey protein supplementation was particularly effective when appetite limits whole-food protein intake.
Emerging Approaches
Several studies in the meta-analysis explored adjunctive peptide therapies including MOTS-c, which may help preserve mitochondrial function in muscle tissue during caloric deficit. The combination of resistance training, adequate protein, and potentially mitochondrial-supporting peptides represents the current best-practice approach to muscle preservation on GLP-1 therapy.
