Could your muscle mass predict weight loss after gastric bypass?
NCT ID NCT07565051
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether the amount of lean (fat-free) body mass before surgery can predict how much weight people lose in the two years after Roux-en-Y gastric bypass. Researchers will follow 91 adults with severe obesity who are scheduled for the procedure, measuring body composition, muscle strength, nutrition, and health changes. The goal is to find a simple way to forecast weight loss success and improve care.
