Early vs. Late Time Restricted Eating vs. Daily Caloric Restriction (NCT05870982)

Effects of Early vs. Late Time Restricted Eating vs. Daily Caloric Restriction on Weight Loss and Metabolic Outcomes in Adults With Obesity

๐Ÿ”ต Active, Not Recruiting Observational / Diagnostic ๐Ÿง  Behavioral & Psychological Program Sponsor: University of Colorado, Denver

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

The goal of this clinical trial is to learn about time restricted eating as a weight loss intervention in adults with obesity. The main questions it aims to answer are: 1. How does the timing of the eating window (early vs late time restricted eating) affect weight loss and changes in metabolic risk factors? 2. How does time restricted eating compare to standard of care (daily caloric restriction) for weight loss and changes in metabolic risk factors? Participants will be randomly assigned to either early time restricted eating, late time restricted eating, or daily caloric restriction. 1. They will be asked to follow the assigned dietary strategy for 1 year and will receive a group-based program for instruction and support. 2. They will be asked at several times during the year to have their weight and body composition measured, provide blood samples, track their food, and wear monitors for physical activity and sleep.
