I picked it up from Martin Berkhan's leangains. It was a lot easier than counting calories for long term maintenance, and it kept the lard off. It made sense to me from an evolutionary point of view; cavemen don't eat "3 square meals" before attacking wooly mammoths, and virtually every religion in the world includes a rigorous fasting period, which, IMO emulates hunter gatherer eating patterns.
For me, the main side effect is I feel a lot more alert, and I waste less time during the day, as preparing and eating food takes up less of it. You know that sleepy feeling you get after a huge breakfast or lunch that makes you reach for an extra cup of coffee? It is no longer a problem. Hunger pangs were an issue for the first two days I did this, and haven't been since then. Oh yeah, and I also feel REALLY FULL when I've eaten too much. Keeping your gut empty from time to time helps you to self regulate.
I think I won the genetic lottery as far as aging goes, and I exercise and try to not eat too much junk food, but "so far so good."
