41 sedentary women (55.3±10 yr, 45.0±4% body fat, 33.7±5 kg/m 2 ) 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 × 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 low fat diet with resistance‐exercise can promote fat loss without loss of FFM.
