OBJECTIVE This study examined the relationship between changes in meal and snack consumption and eating disorder behaviors in a treatment sample of bulimic adults. METHOD Eighty adults with bulimia nervosa (BN) were randomized to one of two treatments. Meal and snack consumption, binge eating frequency, and purging behavior frequency were assessed at baseline, end-of-treatment, and at four month follow-up using the Eating Disorder Examination (EDE). RESULTS Generalized linear models indicated that increased consumption of evening meals over the course of treatment was related to a significant decrease in the rate of binge eating and purging at four month follow-up; these results remained significant when controlling for changes in depression over the course of treatment. CONCLUSIONS The findings support the importance of focusing efforts on developing a pattern of regular evening meal consumption among individuals in the treatment of BN.
