Puzzled about why bulimics aren't skinny

Ive searched as to why bulimics are most often regular size or overweight, but i still haven't found a straight out answer as to why this is true? i mean if they eat a lot then go straight to the toilet and throw it all up shouldn't they be skinny since the food is coming right out a few minutes later?

From Cari: Hi Joan - let's take bulimic A and bulimic B who both consume 4000 calories in one sitting. Bulimic A (let's assume) somehow manages to purge every last bit of those 4000 calories she consumed - well she'd be the bulimic who would probably stay her regular size. Bulimic B only purges 2000 of the calories she ate - so in raality she's still eaten an excess of 200 calories, she'll become the overweight bulimic.

I have read some speculation that the stomach stretches as well - I've just never found research that confirms that. HOpe that answers your question.
