Timed eating may reverse prediabetes in overweight individuals
NCT ID NCT03802253
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether time-restricted eating (eating only during a set window each day) helps overweight or obese people with prediabetes return to normal blood sugar levels. Over 12 months, 142 participants either followed this eating pattern or received standard care. The main goal was to see how many people achieved normal blood sugar, with secondary goals including weight loss and preventing progression to diabetes.
