Resumo146 sedentary women (50±10 yrs, 162±6 cm; 95±20 kg; 46±5% body fat, 36±7 kg/m2) with medically‐managed conditions were assigned to an exercise & no diet group (E) or a low calorie high carbohydrate (HC) or high protein (HP) diet. Diets consisted of 1,200 kcal/d for 1‐wk and 1,600 kcal/d for 9 wks of either HC (55% C, 15% P, 30% F) or HP (15% C, 55% P, 30% F). During weeks 10‐14, subjects consumed a HC maintenance diet (2,600 kcals/d) and were instructed to diet for 2‐d at 1,200 kcals/d if they gain 3 lbs. Subjects participated in a supervised Curves fitness program 3‐d per wk. DEXA body composition and REE measurements were obtained at 0, 10, and 14 weeks and were analyzed by repeated measures ANOVA. Data are presented as means ± SD changes from baseline for the E, HC, and HP groups, respectively, after 10 and 14 weeks. Subjects in the HP group lost more weight (‐2.3±6.6, ‐2.9±7.3; ‐7.9±8.7, ‐8.3±9.8; ‐10.0±6.6, ‐10.6±7.8 lb, p=0.000) and fat mass (‐3.1±6.4, ‐3.4±6.7; ‐3.9±7.6, ‐4.0±7.6; ‐7.6±5.6, ‐8.3±6.8 lb, p=0.001). Subjects in the E group increased REE while subjects in the diet groups only slightly decrease REE (17.1±2.1, 18.0±3.0, 18.5±3.2; 17.3±1.8, 16.8±2.6, 16.5±2.3; 17.0±3.0, 16.4±2.8, 16.5±2.3 kcal/kg, p=0.001). Results indicate that the Curves program is effective to promote weight loss without marked reductions in REE in women with medically‐managed conditions.
