High-protein diabetes formula to protect muscle in people with Type 2 diabetes starting incretin medications
Official title: Evaluating the Efficacy of High-Protein Diabetes Specific Formula (HP-DSF) on Body Composition in Overweight/Obese Patients With Type 2 Diabetes Treated With Incretin Mimetic Drugs
Run by Joslin Diabetes Center · NCT07271043 · Data updated 2026-11-12
This study will test whether a high-protein diabetes-specific formula helps preserve or increase lean muscle in overweight or obese adults with type 2 diabetes who are starting GLP‑1 or dual GLP‑1/GIP incretin medications.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults 18–75 with type 2 diabetes for at least three months, BMI ≥25 kg/m2, adequate kidney function, and who are about to start a GLP‑1 or dual GLP‑1/GIP receptor agonist such as semaglutide, tirzepatide, or dulaglutide.
✕Probably not a fit
People with type 1 diabetes, significant kidney impairment (eGFR <60 mL/min/1.73 m2), very high albuminuria (UACR ≥300 mg/g), recent acute kidney injury, known allergy to the supplement, pregnant or breastfeeding women, or those not using effective contraception are unlikely to be eligible or benefit.

What this trial studies
This randomized clinical trial will give a high-protein diabetes-specific formula to overweight or obese adults with type 2 diabetes who are beginning treatment with GLP‑1 receptor agonists or dual GLP‑1/GIP receptor agonists and compare outcomes to a control group. Participants will be adults aged 18–75 with BMI ≥25 kg/m2 and diabetes diagnosed at least three months prior. The main outcome is change in body composition with a focus on lean muscle mass during initiation of semaglutide, tirzepatide, or dulaglutide therapy. The study is led by Joslin Diabetes Center with industry collaboration and requires in-person visits for measurements.
Why it matters
Potential benefit: If successful, the intervention could help people on incretin medications preserve lean muscle during weight loss, supporting better strength and metabolic health.
How similar studies have gone: High‑protein nutrition has been shown to help preserve lean mass during weight loss in other populations, but combining a diabetes-specific high‑protein formula with incretin-mimetic therapy has been relatively untested.
