It's a weird issue, because there are a number of factors at work. On the extreme ends there are some people that can down 4,000 calories of crap every day, do nothing, and still look great naked; and there are some people that can watch what they eat, work their ass off, and still be significantly overweight. I think the vast majority of us lie somewhere in the wide range between those two extremes (though age matters a lot here too). I was pretty overweight (not horribly so... Like 5'7" 190-200) for most of my teens/early twenties, and I was never bothered by good-natured teasing by friends or co-workers mainly because I understood there wasn't any malice in it on the part of others and I knew it was my doing (i.e. It wasn't a disease, but just my refusal to change things). That being said, it would've bothered me if someone did it with the intent to cause harm. On the flip side, if someone approached me with a "Hey, you wanna talk about a plan to get healthier?", I would've viewed that as a genuinely kind gesture and taken no offense at all. In the end, I changed my habits on my own accord and got down to a healthier weight (generally between 155-165 now), though I am prone to the occasional month or so of terrible eating. But I always bounce back and correct it.
