mel's right, just depends on the situation. and if you guys remember the famous fat bastard (from austin powers) quote "i eat because i'm unhappy, and i'm unhappy because i eat," he just explained it right there lol. eating food is actually an addiction, but it can be bad if you overeat.
me, i eat a lot lol. i have about 3-5 small meals a day, but i don't gain a lot of weight. most i will gain is around 3 pounds, but in a day i lose it. at buffets, i'll get 3-4 plates of food. i love food. i used to eat fast food 3-4 times a week, but i lowered that down to once a week.
