This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing whether the timing of when you eat during the day can help teenagers with obesity lose weight and improve their metabolic health. Researchers will compare two different eating schedules: one where you eat only between 7 AM and 3 PM, and another where you eat between 12 PM and 8 PM. The study will measure how the timing of your meals affects your blood sugar, weight, body composition, sleep, and overall activity levels over 24 weeks.
Adults show promise with earlier eating schedules for weight and metabolic health, but it's unclear whether teenagers can follow such a schedule or if it will work as well for them. This is the first study to test this approach specifically in teenagers with obesity who may be at risk for developing diabetes.

You will be randomly assigned to eat during either an early time window (7 AM to 3 PM) or a late time window (12 PM to 8 PM) for 24 weeks. During the study, you'll visit the research team for assessments where they'll measure your weight, body composition, blood sugar levels, and collect information about your sleep, physical activity, and eating habits. The study is designed to see whether one eating schedule works better than the other for improving your health.
