Study Design

Researchers compared the Early TRE regimen (eating only between 8:00 am and 4:00 pm) and Late TRE regimen (eating only between midday and 8:00 pm) periods, and the habitual eating regimen (more than 14 hours/day). A eucaloric standardized diet [50% carbohydrates, 30% fat, and 20% protein] was provided during the TRE periods but participants consumed their own diets during habitual (free) living conditions.
