Brief Summary

Time restricted feeding (TRF) is a novel form of intermittent fasting that involves confining the period of food intake to 8 h/d (e.g. 10 am to 6 pm) without calorie counting. TRF is effective for weight loss and cardio-protection in obese adults. It is of great interest to see whether subjects can adhere to TRF for longer periods of time, and to see what degree of weight loss that can be achieved with TRF. Accordingly, the aims of this trial are: Aim 1: To determine if TRF can be implemented to facilitate weight loss in obese adults, and Aim 2: To determine if TRF can produce clinically meaningful reductions in plasma lipids, blood pressure, insulin resistance, and inflammatory markers.
