Multiple regression analysis was performed to identify the contribution of changes in body composition, food intake and biochemical measurements to changes in metabolic parameters independent of other factors. The value were expressed as percentage of change ((endpoint - baseline value)/baseline value × 100). Crude model: withouth adjustment, Model 1: adjusted by age, Model 2: adjusted by BMI and Model 3: adjusted by calories intake. BMI: body mass index, TSF: triceps skinfold, WC: waist circumference, TG: triglycerides.
