it is pretty easy. Imagine you were born into a chamber. In this chamber there is nothing.there is a door and you get unending food. You can't move, lying down hurts, and the temperature regulation is fucked up. You grow up in this chamber, thinking everyone else also grows up in a chamber like that. But suddenly you realize no one was guarding the door to get out. they get out, and what do they experience. Nothing. They can't work in the outside world. All their "coping-mechanism" don't work anymore. Everything feels wrong. they have been too long inside crawled up, to forget that they suffered. They go back and say, the door is guarded and that they are "happy" inside. But since most of the people in the world is now growing up in those chambers, they appear to be the norm. So they even further see no problem with it. You have to feel miserable in order to be "alive". So now we lost the biggest power to change, group support.  The easiest way to get rid of all fats, is to emigrate to another country and let all the fats destroy themselves. that is the only solution for it now. there are too many people who don't see a problem in how companies fuck up their food. So this won't change.
