Final answer:
Coping with a bad day by consuming a large amount of food, without subsequent purging, is associated with binge eating disorder.
Step-by-step explanation:
When someone uses food to cope with a bad day by consuming a large amount, without subsequent purging behaviors, it could be a characteristic of binge eating disorder. Unlike bulimia nervosa, where individuals engage in compensatory behaviors such as vomiting or excessive exercise after a binge, binge eating disorder involves recurring episodes of eating large amounts of food followed by feelings of guilt but not by purging. Diagnosing an eating disorder should be done by a healthcare professional, and it often requires a comprehensive treatment plan that may include counseling and medication.
