do you disagree with the notion that eating more food will cause you to gain weight
On just that notion, yes. My boyfriend is a prime counter-example of that notion. That man used to eat one or two large meals a day (large enough to make a fat man jealous) and he was weighing about 115 lbs (also, he is 5' 10").
My point is, weight gain is not a simple matter. For some people, it is easier to lose weight than it is to gain it. Earlier, I was simply trying to correct a common assumption that is actually wrong.
I need to ask raven to start eating more fruit
Pineapples! Omg, pineapples are the best.
