Time-Restricted eating: a simple diet hack to reverse prediabetes?
NCT ID NCT04057339
First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This trial tests whether time-restricted eating (TRE) — limiting all food intake to an 8-10 hour daily window — can improve blood sugar control and metabolic health in people with metabolic syndrome or prediabetes. Participants are randomly assigned to either standard nutritional counseling alone or counseling plus a 12-week TRE schedule. The study measures changes in blood sugar, insulin resistance, cholesterol, and body composition to see if this eating pattern helps regulate the body's daily metabolic rhythms.
