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 .
Motivational "spill-over" during weight control: increased self-determination and exercise intrinsic motivation predict eating self-regulation.
OBJECTIVE Successful weight management relies on at least two health behaviors , eating and exercise . However , little is known about their interaction on a motivational and behavioral level . Based on the Hierarchical Model of Motivation the authors examined whether exercise-specific motivation can transfer to eating regulation during a lifestyle weight control program . The authors further investigated whether general , treatment-related , and exercise motivation underlie the relation between increased exercise and improved eating regulation . DESIGN Overweight/obese women participated in a 1-year r and omized controlled trial ( N = 239 ) . The intervention focused on promoting physical activity and internal motivation for exercise and weight loss , following Self-Determination Theory . The control group received general health education . MAIN OUTCOME MEASURES General and exercise specific self-determination , eating self-regulation variables , and physical activity behavior . RESULTS General self-determination and more autonomous exercise motivation predicted eating self-regulation over 12 months . Additionally , general and exercise self-determination fully mediated the relation between physical activity and eating self-regulation . CONCLUSION Increased general self-determination and exercise motivation seem to facilitate improvements in eating self-regulation during weight control in women . These motivational mechanisms also underlie the relationship between improvements in exercise behavior and eating regulation
