The purpose of this study was to determine if different types of exercise and diet interventions promote greater changes in visceral adipose tissue (VAT). 127 sedentary women (46±12 yr, 45.5±5% body fat, 35.1±5 kg/m2) 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 12‐wks. DEXA body composition with VAT determination was obtained at 0 & 12 wks. MANOVA revealed significant (p=<0.001) time and group x time (p=<0.001) effects. Participants in the CC group experienced greater loss in fat mass (C ‐0.0±2.1; CC ‐4.6±3.7; WW ‐2.2±2.7; JC ‐3.5±3.3; NS ‐2.1±2.7 kg, p<0.001), less loss in FFM (C 0.2±2.3; CC ‐0.3±2.7; WW ‐1.7±2.4; JC ‐1.8±2.3; NS ‐1.8±2.4 kg, p=0.01), and greater reductions in percent body fat (C ‐0.0±1.7; CC ‐3.1±2.5; WW ‐0.7±2.6; JC ‐1.4±2.5; NS ‐0.5±1.7 %, p<<0.001). VAT mass, volume and area decreased over time (p=0.004) with no significant differences among groups. Changes in VAT mass significantly correlated with changes in fat mas (r=0.20) and body fat (r=0.22). Results indicate that different types of diets can differentially affect changes in body composition but promote proportional changes in VAT.
