Which characteristic is least likely to be associated with bulimia nervosa?

Perfectionism is typically associated with other eating disorders, particularly anorexia nervosa, rather than bulimia nervosa. Individuals with bulimia often struggle with issues related to self-image and body weight, frequently participating in cycles of binging followed by compensatory behaviors like self-induced vomiting. Weight fluctuations are a core characteristic of bulimia as a result of these episodes. Extreme dieting can also be prevalent as individuals may attempt to control their weight in between binging episodes. Thus, while perfectionism may influence some individuals with various mental health issues, it is least characteristic of bulimia nervosa compared to the other options presented.
