The idea is that the fast puts you into ketosis, and you burn fat. As I see it, the thing is to try to eat most of the good stuff you would normally eat during the day in the 5 hour window, although some treats won't do any harm
The Warrior Diet
is a similar idea, although Hofmekler doesn't recommend total fasting or eat-anything. It's under- and over-eating. I'm trying a version of this at the moment, eating a breakfast of nuts and seeds. I want to read his book at some point.
