Summary

This 16-week study will use an experimental approach called the Sequential Multiple Assignment Randomized Trial to help determine which combination and sequence of weight loss program features are most effective in people who are at risk for type 2 diabetes. Participants in the study will be initially randomized to consume either a high or reduced carbohydrate diet. After 4 weeks, participants will be identified as Responders (greater than or equal to 2.5% weight loss) or Non-Responders (less than 2.5% weight loss). Responders will continue with their initial randomized group for the remainder of the trial. Non-responders will be re-randomized to 2nd stage interventions of either including additional exercise counseling and training or beginning a time restricted eating protocol for the remainder of the trial.

Conditions

Interventions

BEHAVIORAL

High Carbohydrate Diet

Participants randomized to this group will participate in a group-based weight behavioral management program and consume a high carbohydrate (HC) diet. Because this protocol uses a sequential, multiple assignment, randomized trial (SMART) design, response will be assessed at week 4. Responders will continue with their 1st stage assignment for the remainder of the study. Non-responders will be randomized to 2nd stage intervention of either combine HC diet with time-restricted eating (TRE) or HC diet with additional exercise counseling and support.

BEHAVIORAL

Reduced Carbohydrate Diet

Participants randomized to this group will participate in a group-based behavioral weight management program and consume a reduced carbohydrate (RC) diet. Because this is a sequential, multiple assignment, randomized trial (SMART) design, response will be assessed at week 4. Responders will continue with their 1st stage assignment for the remainder of the study. Non-responders will be randomized to 2nd stage intervention of either combine RC diet with time-restricted eating (TRE) or RC diet with additional exercise counseling and support.
