<qa>  What is the BMIage 85th percentile?In this 3-month pilot study, we will introduce to 40 adolescents at risk for overweight i.e., a BMIage 85th percentile, a structured meal plan consisting of meal replacements, fruits, vegetables, whole grains, lean protein and dairy products. We will encourage and invite at least one parent to the scheduled visits, however, no subject will be eliminated because of lack of parental involvement. Parents will be encouraged to attend group sessions designed to include behavior modification, nutrition education, physical activity recommendations, and food demonstrations as a means of family support for the subject. In this study, we will conduct behavior modification group sessions using lessons which are structured and patterned after the suggestions documented in the LEARN Program for Weight Control. Diet instruction by a registered dietitian will include the appropriate use of meal replacements for a low-fat, low-calorie meal plan. Portion sizes of all foods recommended will be reviewed and a structured meal plan will be developed by the dietitian for subjects to follow. Subjects will return for 12 weekly group sessions.
