 The Feeding-Exercise Trial in Adolescents FETA was a randomised controlled intervention study designed to promote healthy weight in overweigh and obese adolescents through a professional-delivered, community-based program with active parents involvement, focused on supervised physical activity and structured nutritional education. The aim of FETA was to test the efficacy of two intervention groups- physical activity in isolation and combination of physical activity with provision of dietary information- for improving overweight and obesity in adolescents. Our primary hypothesis was that a combined program would be more efficacious than activity in isolation and that activity alone would also be effective compared to control group in improving adiposity profiles in overweight and obese adolescents as well as family activity and feeding habits.
