"A Fat Rant"

Greek salad is good and if I eat a whole one I am full... I'm a really big guy. That is a stupid statement on it's face. I would have said so, in those words, and laughed if I felt like it. "What a stupid thing to say, hahaha! Greek salad fills me up and it tastes good."
I am also uninterested in worrying about embarrassing people or not, I would have called them on it, very politely, continued to labor the point logically, unemotionally, until they conceded.
I am overweight because"
First, I eat the wrong things
Second, My genetics (perhaps interchangeable with the first, but this is a very LARGE part of it)

I, and this is the truth, eat very little... but when I do I tend to eat the wrong things. If I ate more often and the correct things I would lose weight. But, due to being in so much pain, I have very little appetite. Also due to that, I tend to eat what is convenient, the wrong things.
If I did not, I would be thinner. Not thin, due to my genetics, I will never be that.
I do think that people who are VERY thin are obsessive and freaky, because those I have met who are VERY thin are obsessive and freaky.
But, not people who are built to be that way, genetics again, you can tell, they don't look unhealthy and they EAT.
