Whenever you can do something unnatural or at least pretend that you are doing it, it fulfills the ego. Nature cannot fulfill the ego. If you eat and enjoy eating, what is there to brag about? If you make love and you enjoy it, what is there to brag about? But if you become a celibate then there is something to brag about, if you fast then you have something which nobody else has. Then you can feel superior, higher, greater, bigger, chosen. The unnatural has an attraction, although it destroys your whole life, but the attraction is in the ego. And unless we drop this whole game of the ego, hypocrisy cannot disappear from the world.
