The aim of this research was to examine the relationship among body dissatisfaction, dietary restraint, difficulties in emotional regulation and binge eating in women. The survey was conducted online and 1213 subjects, aged 18 to 69, took part in it. Body dissatisfaction, dietary restraint and emotional dysregulation have been shown to be positively related to binge eating. A significant contribution of body dissatisfaction and emotional dysregulation in the explanation of binge eating was obtained, whereby the mentioned variables are also significant predictors of binge eating. Contrary to expectations, dietary restraint did not prove to be a significant predictor of binge eating, nor did it play a mediating role in the relationship between body dissatisfaction and binge eating. On the other hand, emotional dysregulation proved to be a partial mediator of the relationship between body dissatisfaction and binge eating. Ultimately, the serial mediation effect of dietary restraint and emotional dysregulation in the relationship between body dissatisfaction and binge eating was not confirmed. The results point to the importance of difficulties in emotional regulation in the context of the emergence and maintenance of binge eating.
