umm, IMO, Historian, not so much looking down on them, but the fact is if you hang out with people who eat a crap-load of unhealthy food and live the way you did when you were heavy, its going to make your life with loosing weight harder. I think its safe to say we all had to move on from a unhealthy influence to be able to succeed, and sometimes it IS people. I do not look down on people who are fat, I am still fat, so maybe I'm not "there yet" but when I was more fat I wasn't unhappy at all, so its kinda hard for me to judge them. That changed, and my weight changed with it, but as much as I hate to say it, life had been good, so I don't think I judge heavy people that way at all. up until my wife got pregnant with #2 I really never cared if I lost weight, then it was a light switch (thinking.. two of these things running around? how the heck am I gonna keep that up?). I still don't mind being fat, but it just doesn't suit where I need to be for my family.
I think I do look down on people who try and hold me back, be it from a career or a weight loss goal or any kind of success real or perceived. I take that as a insecurity on their part and I just can't help it.
