Time Restricted Eating, Eating Behaviors, and Cardiometabolic Risk in Emerging Adult Women
Study Details
Study Description
Brief Summary
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.

Outcome Measures
Primary Outcome Measures
- Emotional Eating [3 time points: baseline, end of 4-week intervention, end of 4-week follow up]
Dutch Eating Behavior Questionnaire: Emotional Eating Subscale. This subscale is scored from 1-5, with higher scores indicating higher emotional eating.
- External Eating [3 time points: baseline, end of 4-week intervention, end of 4-week follow up]
Dutch Eating Behavior Questionnaire: External Eating Subscale. This subscale is scored from 1-5, with higher scores indicating higher external eating.
- Eating in the Absence of Hunger [Baseline week, weeks 1 and 4 of intervention, weeks 1 and 4 of follow up]
Assessed through surveys sent 5x/day asking about if food was eaten and why.
Secondary Outcome Measures
- Diet Quality [3 time points: baseline, end of 4-week intervention, end of 4-week follow up]
Healthy Eating Index, calculated from 3-day food records. The Healthy Eating Index is scored from 0-100, with higher scores indicating higher diet quality.
- Body composition (total percent body fat) [Baseline and end of 4-week intervention]
Percent body fat measured by DXA
- Body composition (visceral fat) [Baseline and end of 4-week intervention]
Visceral fat measured by DXA
- Body weight [3 time points: baseline, end of 4-week intervention, end of 4-week follow up]
Total body weight
Other Outcome Measures
- Participant experience [End of 9-week study (following 1-week baseline, 4-week intervention, and 4-week follow up)]
Qualitative interview to glean information on participants' subjective experience of the intervention
