The guys over at Precision Nutrition have put up a free web book on Intermittent Fasting.
What is IF? Basically, not eating for a certain period of the day or week, as a dietary strategy. Sometimes you eat, sometimes you don't, but you do it according to a plan.
They tried a few protocols on themselves and discuss the process, the results, and how to do it. It's a good resource, and I especially like the "If you have 10 minutes" and "30 minutes" versions so you know how to get a quick overview depending on your time. It's well organized, too. Worth reading.
FWIW I use IF sometimes, especially when I'm getting ready to compete. I find it's an easy strategy to follow and I feel good once I've adjusted to my feeding windows.
