Serious point though. There are obviously a multitude of factors involved in being overweight, some of them interlinked. Eating more calories than you expend, sedentary lifestyle, medication, head in the sand. There also seems to be some kind of weird pyschology, where some fat people seem to see being fat as good and virtuous, and slim as nasty and deserving of harsh comments. Some fat people would also have you believe that men nearly always prefer fatter women, and that in order to get a man to stay with you, you have to be quite plump. (despite virtually all media images suggesting quite the opposite). In fact, in some ways, being fat seems to be a bit of a parallel universe involving kidding yourself that something is one way when it is another.
I find even the terminology used by some overweight people is rather disengenious. They talk about thin and curvy people. Not slim and fat people. Now no-one looking at me in real life has ever described me as anything other than slim but apparantly to fat people on here I am thin. Distortion of attitudes, anyone? To me, someone like Monica Bellucci or Kim Kardashian is curvy, but not Dawn French or Kathy Brand.
Again seriously, I am honestly shocked and horrified at the amount of weight state of some people. ie how overweight they are, how it affects their movement, how it distorts their features, how it affects what clothes they wear. Nearly all of my friends are slim and active too, so I always find it shocking when I go to the supermarket or round the shops. i would really hate to be unable to walk properly, but instead to waddle, due to carrying too much weight. Its also a British/American thing - people in Holland will generally be told they are too fat if they look like this. Sorry if this is offensive.
