Interventions for Adolescent Obesity

This study will evaluate the short- and long-term use of activity tracking devices and their
effects on short- and long-term weight loss in adolescents. The investigators plan to
establish whether weight loss translates into a change in obesity-related biomarkers
associated with adolescent obesity. Each participant with an activity tracking device will
have the goal of reaching 10,000 steps per day, in addition to their individual fitness plan.
Ten thousand steps per day is the current recommendation for improving health and decreasing
risk of heart disease. Ten thousand steps a day is also a rough equivalent of the US Surgeon
General's recommendation to accumulate 30 minutes of activity most days of the week. Activity
tracking devices will also monitor daily total body energy expenditure and mean sleep hours.
