abstract
51 sedentary women (44.510 yr, 44.94% body fat, 34.06 kg/m2) were randomized to participate in the Curves Complete weight loss and exercise program for 12wks with (CCOS) and without (CCNS) online support that provided access to meal plans and progress monitoring. Body mass, DEXA body composition, and resting energy expenditure (REE) measurements were obtained at 0, 4, 8, & 12 wks and analyzed by MANOVA. Data are presented as changes from baseline after 4, 8, and 12 wks for the CCOS and CCNS groups, respectively. Overall MANOVA revealed that both groups experienced improvements in body composition with minimal effects on REE. An overall significant interaction was observed among groups (p=0.02). Participants in the CCOS group tended to experience more favorable changes in body mass (CCOS 2.61.3, 4.82.3, 6.23.3; CCNS 2.21.9, 3.53.1, 4.34.3 kg, p=0.08) and fat mass (CCOS 1.81.8, 3.52.3, 5.22.9; CCNS 2.02.4, 3.42.8, 3.84.0 kg, p=0.11), while FFM was preserved to a greater degree in the CCNS group (CCOS 0.81.6, 1.22.1, 0.82.5; CCNS 0.01.5, 0.21.6, 0.22.0 kg, p=0.05). No significant differences were seen among groups in percent body fat (CCOS 0.91.8, 1.92.4, 3.32.3; CCNS 1.52.3, 2.52.5, 2.73.4 %, p=0.21) or REE (CCOS 47144, 23176, 0.4154; CCNS 83174, 65184, 102170 kcals/d, p=0.16). Results indicate that adding online access to meal plans and monitoring can promote more favorable changes in body composition while maintaining REE.
