Group	Intervention	Description
Time Restricted Eating	Time restricted eating	Participants will limit their eating (all food and caloric beverages) to an eating window of 10 hours per day for 4 weeks. The eating window must end by 8pm. Water and non-caloric beverages are allowed outside of the eating window. No other changes are required to the types or total amount of food eaten.

Primary Outcome Measures

Name	Time	Method
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

Name	Time	Method
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
