Time Restricted Eating, Eating Behaviors, and Cardiometabolic Risk in Emerging Adult Women
November 17, 2023 updated by: Carly R Pacanowski, University of Delaware
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.
