Summary

This study looks at whether tirzepatide, a drug used for weight loss, affects muscle function and structure in women with obesity. Thirty premenopausal women will receive either tirzepatide or a placebo for 24 weeks. Researchers will measure changes in body composition, muscle strength, and take muscle biopsies to understand how the drug impacts muscle health.
