I always though I was fat as a child, because my parents told me that I was(freaks!!). I was probably 5 or 10 lbs heavier than I should have been, but when I look at pictures, I looked completely normal.
I weighed about 150 when I graduated HS(copletely normal for my 5'10" frame. Within about 10 years I got up to 200, ten more - 250. Now I'm at my heaviest at 300 something.
