Keeping lean muscle during semaglutide or tirzepatide with resistance exercise and extra protein
Official title: LEAN Mass Preservation With Resistance Exercise and Protein During Semaglutide and Tirzepatide Therapy (LEAN-PREP Study)
Run by Dasman Diabetes Institute · NCT06885736 · Data updated 2026-11-12
This trial will test whether adding a practical resistance exercise program and higher protein intake helps adults with obesity keep lean muscle and stay stronger when they start semaglutide or tirzepatide treatment.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older with BMI ≥27 kg/m2 who are starting semaglutide or tirzepatide and are not already doing regular resistance exercise are the intended candidates.
✕Probably not a fit
People who already perform regular resistance training, who cannot safely exercise, or who have contraindications to increased protein intake are less likely to benefit from these interventions.

What this trial studies
Adults with obesity who are starting semaglutide or tirzepatide will be enrolled and asked to follow a pragmatic resistance exercise program and/or increase their protein intake while their medication dose is titrated. A patient and public involvement (PPI) group will help refine the protocol and study materials. The study will measure changes in lean mass and physical function and will also track effects on blood sugar, lipids, liver tests, quality of life, activity and sleep. Interventions are behavioral (exercise and dietary protein) delivered alongside standard medication care.
Why it matters
Potential benefit: If successful, participants could lose less muscle and preserve strength while benefiting from weight loss on semaglutide or tirzepatide.
How similar studies have gone: Previous research suggests resistance exercise and higher protein can help preserve lean mass during weight loss, but combining these approaches with GLP-1/GIP medications like semaglutide or tirzepatide is still being tested.
