First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a smartphone app that coaches older adults to eat more protein can help them maintain muscle mass and strength. Researchers will enroll 140 participants who are open to changing their diet and using an app. The app provides personalized nutritional coaching and exercise recommendations, with the goal of increasing daily protein intake to 1.2 grams per kilogram of body weight.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- nutritional coaching via an app and exercise recommendations
- What this could lead to
- If it works, this could help older adults maintain muscle strength and independence through a simple app-based program.
- What could go wrong
- This is a small, early-stage study (140 participants) focused on dietary changes, not a drug. Results may not apply to everyone, and long-term adherence to the app could be low.
