Physical training literally cures methabolic disorders, except the genetic ones of course, good thing they are extremely rare. Vast majority of them are behavioral.

Moreover, I wasn't judgemetall of obesity before I had met few people with weight problems. One of them even had problems with legs because of that. You know what he did about that? Right, not a damn thing, hasn't even tried. Instead of that he chose only to complain about his poor legs all the time. He never tried to see a doctor, never tried to train. The more you defend this people, the more of them there will be. And of course every one of them claims that they have bad genes or something, except they self-diagnosed it to themselves, because its easier that way. Its always easier to do nothig but to pity yourself, and to look for other people to pity you.
