I'm currently 21 and I've been fighting an uphill battle with my weight since I was in the 5th grade.
My ENTIRE family is over-weight and this makes it hard to do what I need to do. Somewhat unhealthy eating mixed with, I'll admit it, my natural tendency to be lazy. I don't blame them at all though, because I know that it's my own fault that I am the way I am.
The reason I suddenly am sitting up and taking an interest in my need to become healthy is that I was told that I could develop diabetes (it runs in the family) and I had a small scare with what I thought at the time was psoriasis (just in case you don't remember what this is, it's a weight related skin condition).
I need to lose quite a bit of weight, off hand I cannot say how much, but I plan to find out.
