The technical definition is: "Consumption of a very large amount of food in a brief time (e.g., 2 hours) accompanied by a loss of control over how much and what is eaten". Now, a binge can actually just be more then you're comfortable with, like if someone is starving themself then "binges" on a piece of cake, cause to them they would feel out of control. Or a binge can be planned. Do you feel upset/guilty after it? Or do you feel like you were just hungry and ate until you were full? Is it ever for emotional reasons?
