A 16-year-old girl avoids eating in front of others. She is overweight and embarrassed by the amount of food she eats during a regular mealtime. She feels like she cannot control her eating, sneaks food to consume alone in her bedroom after having at least two helpings of food during regular mealtimes, and takes a backpack full of food to eat alone in a classroom while her peers are at lunch. She regularly tells the teacher that her stomach is upset and obtains permission to skip lunch in the cafeteria. Since becoming overweight, she has tried unsuccessfully to diet for a couple days at a time. However, she ends up feeling totally out of control, eats so much that she feels uncomfortably full, and becomes disgusted with herself. She skips physical education classes because she is embarrassed of her weight and has never liked exercise or sports. She is squeamish about taking any pills because of a sensitive gag reflex. Similarly, she does not engage in self-induced vomiting. Which one of the following diagnoses is most likely?
