Protein power: could extra protein fight muscle loss in diabetes?
NCT ID NCT05457088
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether eating more protein (1.5 grams per kilogram of body weight daily, instead of the usual 0.8 grams) could help older adults with type 2 diabetes prevent muscle loss and improve muscle function. Twenty-five participants followed either a high-protein or standard-protein diet, and researchers measured changes in muscle mass, strength, and blood sugar levels. The goal was to see if a simple diet change could break the cycle between diabetes and muscle decline.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- high-protein dietary plan (1.5 g/kg/day)
- What this could lead to
- If it works, this could point toward a simple dietary change to help older adults with type 2 diabetes maintain muscle strength and better control their blood sugar.
- What could go wrong
- This is a very small completed study (25 people) with no blinding or long-term follow-up. Results may not apply to everyone, and a high-protein diet may not be safe for those with kidney issues.
