This. Apparently your taste buds have a turn rate of around 2 weeks (I don't have sauce to back up this claim but it's on the internets somewhere). As in, the cells will change - old ones will die, new ones will form instead of them. So if you make yourself not eat something for 2 weeks, you will stop craving it. This works both ways. If you didn't like something before and then started eating it regularly, chances are you will end up liking it. The key is discipline - something fatties don't have and can't comprehend anyways.
