David often finds himself eating everything in the refrigerator late at night when his family is asleep. He does not really know why he does it, but when he is standing there, everything looks good. He eats food that he would not normally eat. The next day, when his father notices the missing food, David is too embarrassed to admit it was him. What kind of eating disorder does David MOST likely have?
A. bulimia nervosa
B. anorexia nervosa
C. binge eating disorder
D. obsessive diet disorder
