What the trial is, and whether it could suit you

The goal of this randomized controlled trial is to learn how the time of day when calories are eaten affects weight loss in the long-term (12 months). The main aims are to learn: 1. The influence of time-based energy intake goals on longer-term weight loss. 2. The influence of time-based energy intake goals on eating temporal patterns, sleep regularity, and appetite regulation. Researchers will compare whether goals to eat most of a person's calories in the morning or evening work to treat obesity. Participants will: 1. Eat a reduced-calorie, low-fat diet (some participants will have goals to eat their calories at certain times of day based on their group) 2. Be physically active at least 200 minutes 3. Receive a cognitive behavioral intervention
