335 sedentary women (45±10 yrs, 164±7 cm; 92±16 kg; 45±5% body fat) were assigned to an exercise group or one of four diet groups described above for 14‐wks (10 wk diet / 4‐wk maintenance). Subjects participated in a supervised Curves fitness program 3‐d per wk. At 0, 2, 10, and 14 weeks, subjects were weighed, donated fasting blood samples, and had waist and hip measurements determined. Subjects were also questioned about side effects on a weekly basis. Data were analyzed by repeated measures ANOVA and are presented as means ± SD from baseline at weeks 2, 10, and 14, respectively. Significant time and/or interaction effects were observed in total cholesterol (−6.6±14; −3.4±15;−2.0±15 %), LDL‐c (−6.4±19; −2.8±20; −1.8±21 %), triglycerides (−7.1±35; −1.5±37; 0.2±40 %), and glucose (−1.6±13; −1.0±14; −2.9±15 %) with the greatest impact during the diet phases. No significant differences were observed in the cholesterol to HDL ratio. Subjects experienced significant decreases in waist (−1.9±6; −3.4±8; −4.5±7 %) and hip (−1.0±5; −2.3±5; −2.7±5 %) measurements (n=444) with diet groups experiencing greater effects. Although some hematological variables changed over time, there were no clinically significant findings observed in a comprehensive panel of hematological markers evaluated. No clinically significant side effects or adverse events related to the study were reported. Results indicate that participation in the Curves program improves some health‐related blood profiles and decreases hip and waist measurements without adversely affecting general markers of health status.
