Final answer:
Occasional overeating with guilt but no purging is typical of disordered eating but not an eating disorder, differentiating it from bulimia nervosa, where purging follows binge eating, and binge eating disorder, which involves repeated binges without purging.
Step-by-step explanation:
The behavior that is typical of someone who has disordered eating but not an eating disorder is c) Occasional overeating with guilt but no purging.
This behavior differs from eating disorders such as bulimia nervosa or binge eating disorder. Bulimia nervosa is characterized by episodes of binge eating followed by purging through vomiting, excessive exercising, or the use of laxatives. In contrast, binge eating disorder involves repeated binge eating episodes followed by feelings of guilt, but without the compensatory behaviors of purging. Occasional overeating with guilt, but without regular purging or extreme behaviors, suggests a disordered pattern of eating but doesn't meet the criteria for a clinical eating disorder diagnosis.
