100 participants will be randomized 1:1 to follow either a low glycemic load (GL) or standard GL diet for 32 weeks. For the first 16 weeks, all participants will eat enough calories to maintain their baseline weight. During the second 16 weeks, all participants will reduce calorie intake by 500kcal/day, with a goal of losing 5-10% of initial body weight. Participants will complete data collection at baseline (prior to randomization), at 17 weeks (after the weight stable phase) and again after completing the calorie restriction phase.
All participants will receive meal plans and groceries for the duration of the trial.
