I've become interested in trying IF - well, actually, I AM trying it but want to know what I'm doing. Can you point me to articles, books, websites, etc that would give me more information? Or personal experiences - while anecdotal evidence is not scientifically conclusive, it can be fascinating.

I'm also looking for studies on more extended fasting - how long can one go on severely reduced calorie and protein intake (greens and a few nuts) before muscle wasting and metabolic slowdown set in?
