abstract
The purpose of this study was to determine if different diet and exercise programs differentially affect android and/or gynoid body composition changes in sedentary women. 127 sedentary women (4612 yr, 45.55% body fat, BMI 35.15) were randomized to participate in a control group (C) or the Curves Complete program with online support (CC), Weight Watchers Points Plus (WW), Jenny Craig (JC), or Nutrisystem Advance Select (NS) weight loss programs for 12wks. DEXA body composition with android (A) and gynoid (G) measurements were obtained. MANOVA revealed a significant time (p<0.001) and group x time (p=0.006) effects. Participants in the CC group generally lost more AFM (C 8421; CC 479462; WW 162410; JC 275406; NS 237456 g, p=0.01), ABF (C 0.32.6; CC 2.93.6; WW 0.43.7; JC 1.33.2; NS 1.22.5 %, p<0.04), GFM (C 73335; CC 823658; WW 392458; JC 709871; NS 430631, p<0.001), and GBF (C 0.02.1; CC 3.32.9; WW 0.72.6; JC 1.62.4; NS 0.61.9 %, p<0.001) with less loss in GFFM (C 112476; CC 10605; WW 319559; JC 285451; NS 335540, p=0.01). No significant differences were seen among groups in A/G ratio, trunk/leg body fat ratio, or trunk/leg lean mass ratio. Results indicate that different types of diets can differentially affect changes in A and G body composition.Grant Funding Source: Curves International, Inc. (Waco, TX)
