Timing your meals or halving your rice: a new trial tests simple diet hacks for weight loss and blood sugar control

NCT ID NCT07726615

First seen Jul 24, 2026 · Last updated Jul 24, 2026

Summary

This trial compares two simple diet strategies — eating only during early hours or cutting staple foods like rice and bread in half — each combined with an app-guided exercise program, against exercise alone. Researchers want to see which approach helps adults with obesity and prediabetes lose more weight and improve blood sugar over 12 weeks. Three hundred participants in China will be randomly assigned to one of the three groups.
