Study Endpoints
Primary Endpoints
Measures of body composition (fat mass, lean mass and total body water) using Echo MRI-AH and DEXA during the intervention and follow-up phases
24 Weeks

estimate the changes during and after three interventions: (i) calorie restricted diet + a marketed anti-obesity drug (sibutramine), (ii) calorie restricted diet + sibutramine placebo, and (iii) calorie restricted diet + moderate exercise + sibutramine placebo

Measures of body weight and body mass index (BMI) during the intervention and follow-up phases.
24 weeks

estimate the changes during and after three interventions: (i) calorie restricted diet + a marketed anti-obesity drug (sibutramine), (ii) calorie restricted diet + sibutramine placebo, and (iii) calorie restricted diet + moderate exercise + sibutramine placebo

Measures of waist and hip circumference during the intervention and follow-up phases.
24 weeks

estimate the changes during and after three interventions: (i) calorie restricted diet + a marketed anti-obesity drug (sibutramine), (ii) calorie restricted diet + sibutramine placebo, and (iii) calorie restricted diet + moderate exercise + sibutramine placebo

Secondary Endpoints
Mathematical models that use biomarkers of (i) body composition and metabolic status, (ii) macronutrient intake, and (iii) energy expenditure to predict later changes in weight and body composition during the intervention and follow-up phases.
