Protein supplementation combined with resistance training leads to greater preservation of lean mass and strength than training alone. Key point: With adequate protein intake and resistance training, patients can maintainand sometimes increasestrength during GLP-1 therapy despite overall weight loss. Recovery and micronutrients Adequate sleep, hydration, and correction of deficiencies (including vitamin D when present) further support muscle function and recovery. Bottom Line: GLP-1 Medications Improve Body Composition Not Muscle Wasting Semaglutide and tirzepatide do not inherently cause muscle wasting. Most weight lost is fat , and body composition improves. Muscle wasting is primarily a risk of undernutrition , not GLP-1 therapy itself. Protein + resistance training is the most effective strategy to preserve muscle. At Potere Health MD, GLP-1 and GIP therapy is paired with evidence-based nutrition and strength guidance so weight loss is healthier, stronger, and more sustainable
