Excellent post on fasting and how it defeats the devil.
G.K. Chesterton wrote something very beautiful and compelling about the subject of fasting at the end of Chapter 5 of his book on Saint Francis of Assisi:
"As soon as he had been unhorsed by the glorious humiliation of his vision of dependence on the divine love, he flung himself into fasting and vigil exactly as he had flung himself furiously into battle. He had wheeled his charger clean round, but there was no halt or check in the thundering impetuosity of his charge. There was nothing negative about it; it was not a regimen or a stoical simplicity of life. It was not self-denial merely in the sense of self-control. It was as positive as a passion; it had all the air of being as positive as pleasure. He devoured fasting as a man devours food. He plunged after poverty as men have dug madly for gold."

I read this sentiment about fasting not too long ago, maybe on gloria.tv -- "When you are fasting you are dining with the angels."
