Official title
Effects of Early vs. Late Time Restricted Eating vs. Daily Caloric Restriction on Weight Loss and Metabolic Outcomes in Adults With Obesity
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
