55 sedentary women (66±5 yrs, 79±11 kg; 44±4% body fat) participated in the Curves circuit resistance‐training program 3‐d per wk for 14 wk. Subjects were assigned to an exercise only group (E) or a high carbohydrate (HC) or high protein (HP) diet group. Diets consisted of 1,200 kcal/d for 1‐wk, 1,600 kcal/d for 9 wks, followed by a 4‐wk maintenance phase (2,100 kcals/d). The HC group diet contained 55% CHO, 15% PRO, and 30% Fat while the HP diet contained 7–15% CHO, 55–63% PRO, and 30% Fat. The maintenance phase consisted of 55% CHO, 15% PRO, and 30% Fat. Data were analyzed by repeated measures ANOVA and are presented as means ± SD changes from baseline for the E, HC, and HP groups, respectively. Subjects significantly lost weight (p=0.001) after 10‐wks of dieting (−0.9±1.8; −2.2±2.3; −4.1±3.9 kg) and maintained weight loss during the 4‐wk maintenance phase (−0.9±1.8; −2.3±2.4; −3.9±2.6 kg). Subjects following the HP diet experienced the greatest weight loss. No significant time or group x time effects (p=0.88) were seen in REE values after 10‐wks of dieting (−0.09±1.9; −0.12±1.1; −0.13±1.3 kcal/kg/d) or the 4‐wk maintenance phase (0.27±1.6; 0.52±1.6; −0.13±1.5 kcal/kg/d). Results indicate that senior women participating in a resistance training program can achieve significant weight loss without reducing REE.
