41 sedentary women (55.3±10 yr, 45.0±4% body fat, 33.7±5 kg/m2) were randomized to participate in a control group (C) or the Curves Complete® (CC) weight loss and circuit resistance-exercise program for 12-wks. Participants in the CC program followed an energy-restricted diet (30% C, 45% P, and 25% F) while participating in a circuit resistance-training (3 d/wk) and walking (30 min, 3/d wk) program. Body mass, DEXA body composition, and resting energy expenditure (REE) measurements were obtained at 0, 4, 8, & 12 wks and analyzed by MANOVA. Data are presented as changes from baseline after 4, 8, and 12 wks for the C and CC groups, respectively. Participants in the CC program lost significant amounts of body mass (C -0.05±1.6, -0.1±2.2, 0.1±3.1; CC -2.1±1.7, -3.1±2.6, -3.9±3.2, kg, p=0.001), fat mass (C -0.0±2.2, 0.2±2.3, -0.0±2.0; CC -2.2±1.4, -2.8±2.0, -4.1±2.4 kg, p=0.001) and body fat (C 0.1±1.7, 0.3±1.7, -0.1±1.7; CC -1.8±2.1, -2.2±2.3, -3.5±2.5 %, p=0.001) than controls with no time (p=0.54) or group x time effects on FFM (C -0.1±1.4, -0.1±1.7, 0.1±2.3; CC 0.2±1.8, 0.1±1.9, 0.5±1.6 kg, p=0.89). REE tended to differ among groups (C -20±149, 17±180, 39±190; CC -30±140, -65±169, -85±130, kcal/d, p=0.03). Results indicate that post-menopausal women who participate in an energy deficit higher protein and lowfat diet with resistance-exercise can promote fat loss without loss of FFM.

41 sedentary women (55.6±10 yr, 45.0±4% body fat, 33.7±5 kg/m2) were randomized to participate in a control group (C) or the Curves Complete® (CC) weight loss and circuit resistance exercise program for 12-wks. Participants in the CC program followed an energy-restricted diet (30% C, 45% P, and 25% F) while participating in a circuit resistance-training (3 d/wk) and walking (30 min, 3/d wk) program. Fasting blood samples were obtained at 0, 4, 8, & 12 wks and analyzed by MANOVA. Data are presented as changes from baseline after 4, 8, and 12 wks for the C and CC groups, respectively. Overall MANOVA analysis revealed a significant time (p=0.004) and group x time (p=0.002) differences. Univariate analysis revealed significant time effects for TG, CHL, and LDL and that participants in the CC group experienced significantly different changes in blood glucose (C 1.7±8, 2.6±6, -1.3±8; CC 0.6±8, -3.2±6, -0.8±7 %, p=0.04) and CHL (C 0.6±12, -0.3±12, -2.2±11; CC -11.2±11, -9.5±10, -11.2±9 %, p=0.005) with no significant differences in TG (p=0.14), HDLc (p=0.37) or LDLc (p=0.11). Results indicate that adherence to a high protein and low fat energy restricted diet while participating in a resistance-based circuit training program promotes favorable changes in blood glucose and some blood lipids in postmenopausal women.
