Which behaviors might Corey engage in that are characteristic of bulimia nervosa?

Corey might engage in self-inducing vomiting, which is a behavior commonly associated with bulimia nervosa. This eating disorder is characterized by cycles of binge eating followed by purging to prevent weight gain. The act of self-inducing vomiting is a method some individuals use to attempt to rid their bodies of the calories consumed during binge episodes. This behavior is driven by intense feelings of guilt, shame, and fear of weight gain after overeating.

The other options, such as increasing protein intake, reducing water intake, or maintaining a balanced diet, do not align with the patterns seen in bulimia nervosa. Typically, individuals with this disorder struggle with extreme behaviors that deviate from healthy dietary practices, often leading to detrimental physical and mental health consequences.
