Here goes:
Typical story, chubby kid(born that way, not through overeating, parents wouldn't have that), ostracized at school, teased, carried that through years growing up, success here in there, especially in athletics through hard work. Once the college years started, too busy to exercise and eat right, got larger and larger, which in turn doesn't help in the social realm, which leads to depression, which lead to more bad eating habits(no other vices in life, just enjoyment of lots of ****ty food).
Once you surpass a certain size the chances of losing it and keeping it off are like slim to none, but attempts are constantly made, lost 50 to 100 here, gain it all back there, do it again and again, always something that makes you go back to how it was before, usually a major change in life derails you. Finally got gastric bypass surgery, have kept off around 140 lbs from it(though got a good deal lower from the first initial rush), but am still a large dude, and no more attractive than I was before, but at least not in deaths range, due to the ability to exercise and such, which is nice.
So really, nothing precluding me from losing all the weight, except for history, genetics, lack of will power, and the ebb and flow of life.
