abstract
126 sedentary women (4412 yr, 44.85% body fat, 35.46 kg/m2) were randomized to participate in a control group (C) or the Curves Complete 90day Challenge (CC), Weight Watchers Points Plus (WW), Jenny Craig (JC), or Nutrisystem Advance Select (NS) weight loss programs for 12wks. Fasting blood samples were obtained at 0, 4, 8, and 12 wks and analyzed by MANOVA. Data are presented as percent changes from baseline after 12wks. Participants in the CC group had greater changes in TG (C 1.923; CC 8.328; WW 2.732; JC 15.143; NS 11.129 %, p=0.03) with TG levels increased in the JC and NS groups. Although some trends were observed, no significant interactions were observed among groups in total CHL (C 1.511; CC 5.99; WW 1.012; JC 2.311; NS 3.815 %, p=0.22), HDLc (C 3.79; CC 0.614; WW 1.113; JC 5.016; NS 2.96.3 %, p=0.008) and hip 4.013 %, p=0.45), LDLc (C 3.317; CC 7.09; WW 11.052; JC 2.712; NS 6.121 %, p=0.12), the ratio of CHL/HDLc (C 2.96.3 %, p=0.008) and hip 2.424; CC 4.011; WW 0.313; JC 4.816; NS 0.112 %, p=0.48), or blood glucose (C 1.39; CC 2.416; WW 4.819; JC 1.610; NS 2.916 %, p=0.93). Results indicate that participation in the CC program promotes more favorable changes in TG levels than other popular weight loss programs and that adherence to popular diets may affect blood lipids differentially.
