Time Restricted Eating Pilot - Bariatrics

July 15, 2020 updated by: Kelly Allison, University of Pennsylvania
Bariatric surgery patients have a variable course of weight loss, maintenance and regain. Time restricted eating is an approach that may help individuals lose weight and improve metabolic functioning. We propose a pilot 12-week trial of a 10-hour time restricted eating intervention among post-bariatric surgery patients. The intervention would consist of weekly sessions for 4 weeks, followed by one session every two weeks through 12 weeks, with weight change as the primary outcome.

Detailed Description

We propose a pilot 12-week trial of a 10-hour time restricted eating intervention among post-bariatric surgery patients. The intervention would consist of weekly sessions for 4 weeks, followed by one session every two weeks through 12 weeks, with weight change as the primary outcome. We will provide behavioral weight loss education to the patients and monitor how many calories they are taking in once per week.

Intervention / Treatment
Other: Intervention
To test the effects of a 10-hour time restricted eating intervention before and after the 12 weeks of treatment on weight (primary), caloric and macronutrient intake, and a variety of psychosocial measures, including sleep, physical activity, blood pressure and eating behaviors (all secondary).
We propose a pilot and feasibility trial of a 10 hour time restricted eating intervention among post-bariatric surgery patients.
