TREating Pediatric Obesity

Participants will receive nutritional education sessions and will be instructed to maintain an intake window of at least 13 hours a day, preferably every day of the week and in any case at least 6 days a week.

A personalized progression will be established to progressively reduce the intake window during the first 10 days of intervention. After these first 10 days, the participants will be prescribed to limit food intake to a maximum of 10 hours a day, at least 5 days a week. Participant can freely select the time of day to place the intake window. However, it will be recommended to avoid making the last intake in the 3 hours before going to bed. After 4 weeks of intervention, the dietitian will invite them to reduce the intake window to 9 or 8 hours, if they consider it feasible, maintaining this new intake window during the last 4 weeks of intervention. The intake window can be maintained at 10 hours until the end of the study.
