About

The goal of this clinical trial is to learn how exercise and diet quality affect the health of adolescents with obesity. The main questions it aims to answer are:

  • Does exercise improve cardiometabolic health in adolescents with obesity?
  • Does enriching the diet with fruits and vegetables (FV) improve cardiometabolic health in adolescents with obesity?
  • Do exercise and FV diet together provide greater health benefits than either alone in adolescents with obesity?

Researchers will compare four groups to see how exercise and diet impact health:

  • Standard Care Group: Receives the usual care for obesity.
  • Exercise Group: Receives weekly exercise coaching and participates in a 12-week exercise program.
  • Diet Group: Receives weekly dietary coaching and eats a diet enriched with fruits and vegetables for 12 weeks.
  • Combined Exercise and Diet Group: Receives both exercise and dietary programs, namely weekly exercise and dietary coaching, participation in a 12-week exercise program, and daily consumption of fruits and vegetables for 12 weeks.

During the 12-week study, participants will attend three study visits to:

  • Provide blood, stool, and urine samples.
  • Answer questions about health, sleep, diet, and physical activity.
  • Undergo body scans to measure fat, lean, and bone mass.
  • Complete blood vessel function and liver fat content assessments.
  • Assess resting exergy expenditure.
  • Complete fitness tests.
  • Wear a fitness tracker to monitor physical activity and sleep patterns.
