The purpose of this study was to determine if different types of exercise and diet interventions promote greater changes in visceral adipose tissue (VAT). 54 sedentary women (34±8 yrs, BMI 35±6) were randomized to participate in the Curves (C) or Weight Watchers (W) weight loss 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 CHO:PRO). 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, received weekly counseling, and were encouraged to exercise. DEXA body composition with VAT was determined at 0 & 16 wks. MANOVA revealed a significant time (p<0.001) and group x time (p=0.035) effect. Both groups lost a similar amount of weight (W ‐6.3±4, C ‐4.8±4 kg, p=0.17), fat mass (W ‐3.1±6, C ‐5.9±6 kg, p=0.13), and VAT mass (W ‐98±468, C ‐240±445 g, p=0.26). Subjects in the C group experienced greater gains in FFM (W ‐3.3±5.9. C +1.2±4.1 kg, p=0.002) and tended to lose more body fat (W ‐1.1±8, C ‐4.5±5.5 %, p=0.07). Changes in VAT mass significantly correlated with changes in weight (r=0.38), fat mass (r=0.73), FFM (r=‐0.62), and body fat (r=0.64). Results indicate that different types of diets can differentially affect changes in body composition and VAT. Grant Funding Source : Curves International, Inc. (Waco, TX)
