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 .
Reciprocal effects of treatment-induced increases in exercise and improved eating, and their psychosocial correlates, in obese adults seeking weight loss: a field-based trial
Background A better underst and ing of interrelations of exercise and improved eating , and their psychosocial correlates of self-efficacy , mood , and self-regulation , may be useful for the architecture of improved weight loss treatments . Theory-based research within field setting s , with sample s possessing high probabilities of health risks , might enable rapid application of useful findings . Methods Adult volunteers with severe obesity ( body mass index [ BMI ] 35–50 kg/m2 ; age = 43.0 ± 9.5 y ; 83 % female ) were r and omly assigned to six monthly cognitive-behavioral exercise support sessions paired with either group-based nutrition education ( n = 145 ) or cognitive behavioral methods applied to improved eating ( n = 149 ) . After specification of mediation models using a bias-corrected bootstrapping procedure , a series of reciprocal effects analyses assessed : a ) the reciprocal effects of changes in exercise and fruit and vegetable intake , result ing from the treatments , b ) the reciprocal effects of changes in the three psychosocial variables tested ( i.e. self-efficacy , mood , and self-regulation ) and fruit and vegetable change , result ing from change in exercise volume , and c ) the reciprocal effects of changes in the three psychosocial variables and exercise change , result ing from change in fruit and vegetable intake . Results Mediation analyses suggested a reciprocal effect between changes in exercise volume and fruit and vegetable intake . After inclusion of psychosocial variables , also found were reciprocal effects between change in fruit and vegetable intake and change in mood , self-efficacy for controlled eating , and self-regulation for eating ; and change in exercise volume and change in mood and exercise-related self-regulation . Conclusion Findings had implication s for behavioral weight-loss theory and treatment . Specifically , results suggested that treatments should focus upon , and leverage , the transfer effects from each of the primary weight-loss behaviors ( exercise and healthy eating ) to the other . Findings on psychosocial correlates of these behavioral processes may also have practical applications
