42 sedentary women (33±7 yrs, 164±7 cm; 93±19 kg; 46±7% body fat, 35±6 kg/m 2 ) were randomized to participate in the Curves (C) or Weight Watchers (W) programs for 16‐wks. Participants in the C program followed a 1,200 kcal/d diet for 1‐wk and 1,500 kcal/d diet for 3 wks (30:45). Subjects then ingested 2,000 kcals/d for 2‐wks (45:30 CHO:PRO) and repeated this diet while participating in the Curves with Zumba program 3‐d‐wk. Remaining subjects followed the W point‐based diet program. Fasting blood samples were obtained at 0, 4, 10, & 16 wks and analyzed by MANOVA. Both programs promoted significant decreases (p<0.05) in total CHL (−5.9±11%) and LDL‐c (−8.8±17%). Significant interactions were seen in changes in total CHL (C −4.0±12, −1.9±9, −2.2±11; W −5.9±8, −7.1±10, −9.0±11%, p=0.03), LDL‐c (C −4.0±18, 1.8±15, −3.2±19; W −5.8±12, −6.8±15, −13.4±15%, p=0.03), HDL‐c (C −3.5±12, 0.1±10, 1.6±16; W −9.3±11, −9.9±12, −0.1±13%, q p=0.002), the ratio of CHL:HDL (C 1.7±11, −0.4±9, −1.9±12; W 5.1±13, 4.2±13, −7.9±10 %, q p=0.009), TG (C −6.3±27, −10.3±13, −5.4±22; W 4.1±25, −3.4±31, −0.2±43%, c p=0.03), and blood glucose (C 2.1±15, 0.7±13, −2.6±12; W −2.2±7, −3.2±10, −2.1±8%, q p=0.05). Results suggest that adherence to the W program may promote more favorable changes in blood lipids than cycling caloric intake. However, participating in the C structured diet and exercise program had more beneficial effects on HDL‐c and TG levels.
