Time-restricted Eating Acceptability, Efficacy and Safety in Obesity

Recruiting now · Not applicable

Conditions studied: Time Restricted Eating

In brief

A randomized controlled trial to determine adherence, acceptability and safety of time restricted eating (TRE) in healthy, sedentary, free-living adults with obesity between the ages of 19-65 years when following 16:8 TRE for 8 weeks. This 9-week study includes a baseline week and 8 weeks of the intervention period. Participants are randomly assigned to the TRE or the non-fasting control group. The TRE group will consume calorie containing food and drink only over an 8 hour period and rest of the 16 hour would be fasting. Adherence to TRE and calorie intake are the primary outcomes. Motivators, facilitators and barriers to TRE, hunger and cravings levels, weight bias internalization, body composition (weight, body fat%, fat mass and muscle mass) , Healthy Eating Index (HEI) to assess diet quality, skin carotenoid levels, disordered eating risk, sleep quality, and perceptions of health and well-being are secondary outcomes.
