Just to add my opinion: if you wolf down food, you will eat more than you stomach can handle, causing it to stretch. However, if you eat slowly and stop when your body tells you to stop, then the stomach won't stretch substantially. Now the initial stretching won#t do anything bad to you (you won't be able to notice a difference if it happens once), but if it stretches repeatedly it'll trigger the replication of the tissue that composes the stomach, which in turn leads to a larger stomach, so that it won't stretch anymore. A larger stomach will mean it'll need more food to fill up, and people that continue wolfing down food will expand quickly in the horizontal plane.
However that doesn't mean that just eating slowly solves the problem. If you eat slowly, to the point of feeling like you burst, it'll have the same effect as if you'd wolfed down all that food.
Anyway, it isn#t guaranteed that you'll grow fat if you wolf it down, it just increases the risk of obesity. There're also people with a genetic disposition that prevents storing their excess carbohydrates in fats. This is just one example of influences that aren't considered by most tests. Anyway, that should be Tiffanys field of expertise^^
