Resumo693 sedentary women (47±12 yrs, 163±7 cm; 92±17 kg; 45±4% body fat) were assigned to a control group (C), an exercise group (E); or, a high carbohydrate or a high protein diet group for 10‐weeks. Diets consisted of 1,200 kcal/d for 1‐wk and 1,600 kcal/d for 9 wks. Diets were 55% CHO, 15% P, and 30% F (HC) or 7‐15% CHO, 55‐63% P, and 30% F (HP). Subjects in the exercise groups participated in a supervised Curves fitness program 3‐d per wk. DEXA body composition and REE measurements were obtained at 0 & 10 wks and were analyzed by repeated measures ANOVA. Data are presented as means ± SD changes from baseline for the C, E, HC, and HP groups, respectively. Subjects who dieted experienced a significantly greater (p<0.001) loss in scanned total mass (‐0.4±2.2; ‐0.4±2.1; ‐2.9±3.6; ‐3.8±4.0 kg), fat mass (‐0.4±2.0; ‐0.7±1.8; ‐2.3±2.8; ‐3.0±3.3 kg), and body fat (‐0.3±1.9; ‐0.7±1.6; ‐1.3±2.1; ‐1.6±2.9 %). Weight loss and fat loss in the HP group was significantly greater than the HC group although changes in percent body fat were not significantly different. REE decreased slightly in the HC, HP, and C groups while increasing in the E group (‐0.6±2.1; 0.3±2.0; ‐0.4±2.1; ‐0.7±2.5 kcal/kg/d). Results indicate that the Curves program is effective to promote weight loss without marked reductions in REE particularly when following a HP diet.
