NCT ID NCT05866406
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether eating all meals within a 9-hour window each day for 12 weeks can improve insulin sensitivity and other heart health markers in 100 adults with obesity and prediabetes. Participants will be randomly assigned to either a 9-hour eating window or a 14-hour window, with both groups receiving healthy diet advice. The goal is to see if time-restricted eating works even without weight loss.
