not sure if anyone has pointed it out yet because its late and i need to sleep so i only skimmed the thread, but I'd like to point out the following website

Leangains - Intermittent Fasting for Strength Training and Fat Loss

the guy purports a method he dubs "intermittent fasting" where he makes use of 16 hour fasts every day in order to take advantage of the lipolysis-enabling hormonal state that your body finds itself in during a fasting period. He does include adequate daily feeding so this is not in any way akin to self-inducing an eating disorder.

IFing is fairly common. A lot of people have their own systems that work for them, like doing one 24-hr fast per week or an 18-hr fast twice a week. As with all things, it's finding a rhythm and schedule that works for you.
