Great quote on that hungry feeling from an article at MIT Technology Review:
How to cope with the hunger? I attempted to enjoy it. I thought of the movie Lawrence of Arabia, in which T.E. Lawrence says, “The trick is not minding that it hurts.” I told myself that the mild ache was only the sensation of evaporating fat. That interpretation has some basis in physics. When you lose weight, most of your fat is converted to the gases carbon dioxide and water vapor, and so you get rid of fat by breathing it out of your body.
Love that jedi mind trick. That hungry feeling isn’t my body complaining about lack of food. It’s my body hard at work, eliminating unnecessary fat.
