NCT ID NCT03578887

First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This study used MRI brain scans in twins to investigate whether brain inflammation (gliosis) plays a role in obesity and weight regain. Researchers compared people undergoing behavioral weight loss, bariatric surgery, and healthy-weight controls. The goal was to understand why weight loss is often temporary and whether surgery resets the brain's weight set point.
