Time Restricted Eating, Eating Behaviors, and Cardiometabolic Risk in Emerging Adult Women

University of Delaware36 enrolled

Overview

The purpose of this study is to assess how time restricted eating interventions impact eating behaviors, diet quality, and body composition in women ages 20-29 years. Participants will be asked to limit all food and drinks (except water and some non-caloric beverages) to a 10-hour period during the day for four weeks. Participants will follow their usual eating and activity patterns for one week before starting, and follow whatever eating pattern they want for 4 weeks after finishing.
