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 .
Psychobehavioural Factors Are More Strongly Associated with Successful Weight Management Than Predetermined Satiety Effect or Other Characteristics of Diet
This study aim ed to investigate factors associated with weight management , especially whether satiety value of food as a part of a weight-maintenance diet would affect self-regulation of food intake and weight management . Altogether 82 obese subjects completed the study consisting of weight-loss and weight-maintenance ( WM ) periods . During the WM , subjects were r and omized into higher- and lower-satiety food groups . No differences were observed in the changes in body weight , energy intake , or eating behaviour between the groups , even despite the different macronutrient compositions of the diets . However , when regarding all study subjects , success in WM was most strongly associated with a greater increase in the flexible control of eating and experience of greater easiness of WM and control of food intake and a greater decrease in uncontrollable eating and psychological distress . Psychobehavioural factors seem to be more strongly associated with successful weight management than the predetermined satiety effect or other characteristics of the diet
