Identified mediators for medium-/long-term weight control were higher levels of autonomous motivation , self-efficacy/barriers , self-regulation skills ( such as self-monitoring ) , flexible eating restraint , and positive body image .
For physical activity , significant putative mediators were high autonomous motivation , self-efficacy , and use of self-regulation skills .
For dietary intake , the evidence was much less clear , and no consistent mediators were identified .
Conclusions This is the first systematic review of mediational psychological mechanisms of successful outcomes in obesity-related lifestyle change interventions .
Despite limited evidence , higher autonomous motivation , self-efficacy , and self-regulation skills emerged as the best predictors of beneficial weight and physical activity outcomes ; for weight control , positive body image and flexible eating restraint may additionally improve outcomes .
These variables represent possible targets for future lifestyle interventions in overweight/obese population
Background Relapse is high in lifestyle obesity interventions involving behavior and weight change .
Identifying mediators of successful outcomes in these interventions is critical to improve effectiveness and to guide approaches to obesity treatment , including re source allocation .
This article review s the most consistent self-regulation mediators of medium- and long-term weight control , physical activity , and dietary intake in clinical and community behavior change interventions targeting overweight/obese adults .
Effects of treatment differences on psychosocial predictors of exercise and improved eating in obese, middle-age adults.
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 r and omly selected to 6-month treatments of cognitive-behavioral exercise support paired with either st and ard 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 st and ard nutrition education is incorporated
