However the specific mechanisms underlying its successful regulation remain unclear. This study examined one potential mechanism by testing a model in which improved body image mediated the effects of obesity treatment on eating selfregulation. Further this study explored the role of different body image components. Methods Participants were 239 overweight women age yr BMI kg m2 engaged in a 12month behavioral weight management program which included a body image module. Self-reported measures were used to assess evaluative and investment body image and eating behavior. Measurements occurred at baseline and at 12 months. Baseline-residualized scores were calculated to report change in the dependent variables. The model was tested using partial least squares analysis. Results The model explained 18-44 of the variance in the dependent variables. Treatment significantly improved both body image components particularly by decreasing its investment component f2 .32 vs. f2 .22 . Eating behavior was positively predicted by investment body image change p .001 and to a lesser extent by evaluative body image p .05 . Treatment had significant effects on 12-month eating behavior change which were fully mediated by investment and partially mediated by evaluative body image effect ratios .68 and .22 respectively . Conclusions Results suggest that improving body image particularly by reducing its salience in one s personal life might
