BACKGROUND: Behavioral interventions for weight-loss have been largely unsuccessful. Exercise is the strongest predictor of maintained weight loss and much of its effects may be from associated changes in psychosocial factors. METHODS: Middle-aged, formerly sedentary adults with severe obesity were randomly selected to 6-month treatments of cognitive-behavioral exercise support paired with either standard nutrition education (n=99) or nutrition change supported by cognitive-behavioral means with an emphasis on self-regulation (n=101). RESULTS: Overall improvements in self-efficacy and self-regulation for both exercise and managed eating, and mood, were found, with significantly greater improvements associated with the cognitive-behavioral nutrition condition in self-regulation for eating and mood. Change scores trended toward being stronger predictors of increased exercise and fruit and vegetable intake than scores at treatment end. Multiple regression analyses indicated that significant portions of the variance in both increased volume of exercise (R2=0.45) and fruit and vegetable intake (R2=0.21) were explained by changes in self-regulatory skill usage, self-efficacy, and mood. CONCLUSIONS: Cognitive-behavioral methods for improved eating paired with behavioral support of exercise may improve weight loss through effects on the psychosocial factors of self-regulation, self-efficacy, and overall mood more than when standard nutrition education is incorporated.
