Time-Restricted eating: a simpler way to control diabetes?
NCT ID NCT05290246
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether time-restricted eating (TRE) — eating only during a set daily window — can help control blood sugar and weight in adults with type 2 diabetes. 115 overweight or obese adults who take metformin were asked to follow TRE for 24 weeks. The goal was to see if TRE is a practical alternative to counting calories for managing diabetes.
