The notion that if you don’t eat, you’ll experience an increasing feeling of hunger the longer it lasts, is simply not true. In fact, I daresay that after fasting for a few days, you will actually feel more normal than perhaps you ever have before. And when you don’t think so much about what you’ll eat, when you’ll eat, where you’ll eat, and all the other social customs surrounding food, it frees you up to do other things. You’ll realize the urge and desire to eat is more mental than physical.
