Some diseases can contribute to obesity, but being overweight is largely a choice. While some of us are genetically predisposed to being overweight, most people who are large simply don't want to lose weight--if they wanted to, they could, it's just not easy.
I, for one, don't give a rat's ass about weight. I'm "morbidly underweight," which is to say my lack of fatty tissue and poor diet is negatively impacting my health. But be you 50kg or 250kg, I don't care. The only time weight is a problem, in my eyes, is when it stops you from doing what you want in your life. Don't lose weight, get in shape or work out and eat right because other people want you to. It's your life and you only get to do it once, so do it exactly how you want to.
