What this study is about
This study is being performed to understand the effects of a lifestyle modification and sleep intervention on weight loss outcomes in adolescence. The main question the study aims to answer is: \- What are the initial effects of a lifestyle modification and sleep intervention, including effects on weight, eating behaviors and dietary intake, and sleep? Participants will: * Participate in remote, group-based, weekly weight loss and sleep coaching for 16 weeks. * Complete study assessments at baseline (pre-intervention), mid-intervention, and post-intervention. * Complete daily sleep diaries for three 7-day periods at each assessment point.
A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Lifestyle Modification and Sleep Intervention
Behavioral
This study is being performed to develop, refine, and test the effects of a group lifestyle modification intervention augmented with a sleep intervention on weight loss, eating behaviors, and sleep outcomes. Results from this study will inform future studies to test the efficacy of this intervention. This intervention is being offered as part of a research study within Drexel University's WELL Center. Participants will receive remote, group-based, weekly weight loss and sleep coaching (90 minutes per coaching session) for 16 weeks.
Primary outcomes
Percent of 95th percentile BMIFrom enrollment to the end of the study (approximately 4 months)Height and weight will be measured at each assessment and used to calculate percent of 95th percentile BMI.
Tri-ponderal mass indexFrom enrollment to the end of the study (approximately 4 months)The investigators will also calculate tri-ponderal mass index (TMI; i.e., mass divided by height cubed) from measurements of height and weight.
Body fat percentageFrom enrollment to the end of the study (approximately 4 months)Body fat percentage will also be derived from the Aria Air scale.
