Which of the following phrases does not correctly describe BOTH bulimia nervosa and binge eating disorder?

The phrase that does not accurately describe both bulimia nervosa and binge eating disorder is related to the symptoms of purging. Bulimia nervosa is characterized by episodes of binge eating followed by compensatory behaviors, which often include purging methods such as vomiting, excessive exercise, or the misuse of laxatives. In contrast, individuals with binge eating disorder do not engage in purging behaviors. Instead, they may frequently eat large amounts of food without the subsequent compensatory actions.

Thus, while both disorders involve episodes of consuming large quantities of food and can lead to serious health issues, bulimia nervosa specifically includes the act of purging, making this phrase exclusive to that disorder and not applicable to binge eating disorder. The other choices accurately reflect characteristics that are common to both conditions.
