Have trouble identifying the point at which you have had enough food to live on? Tend to eat as if in a race, too fast or more greedily than most other people? Tempted to eat impulsively between meals? Feel that you have to clean your plate without thinking, or without sensing satiety? Want a dessert even when you are full or over-full (not counting Thanksgiving)? Occasionally conceal your eating habits out of shame? Feel bad about yourself when you know you have eaten more than you need?
These are the main signs of the fairly-common "binge eating disorder." You do not have to pathologize it - it could also be called a "bad habit," or, from a moral standpoint, "gluttony," one of the Christian 7 deadlies. A First World problem, but not as much as you would think: there is more overweight among the "poor" around the world these days than among the more prosperous. BED people eat as if on an anti-starvation feeding mission rather than at a social occasion with food as an enhancement.
Like many so-called "disorders," it is mainly medically-defined as such for insurance purposes but it is a real pattern of impulsivity or compulsivity, often manifest in many areas of functioning. If it's a problem, it is easily addressed. There are pills for it.
