First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests different weight-loss strategies for adults aged 50 to 75 with obesity. Participants will follow either a high-protein or standard-protein diet for 16 weeks. Those who don't respond well may then receive extra protein supplements or resistance exercise training. The goal is to find the best way to lose weight while preserving muscle mass. The trial plans to enroll 250 people and will track weight and body composition over a year.
