There's a lot of scientific evidence supporting a ketogenic lifestyle, distinguishing this movement from fad diets and Attia from a Guru status. If you're interested I would recommend the following book: http://amzn.com/0983490708

Better would be peer-reviewed journal articles. A lot of books have a tendency to promote the views of the author over providing a balance of information.

Here is a short list of both author's peer-reviewed research papers on the topic. http://www.artandscienceoflowcarb.com/research/

Interesting. Their two-week adaptation time is consistent with what I noticed in myself. I don't do the diet this strictly. I simply commented to a trainer that I have never been able to successfully work out hard- meaning weight lifting an anaerobic interval training- and lose weight simultaneously.

He suggested I try working out while fasting. Just don't eat 3-4 hours before working out, and have a high quality protein 'meal' (I drink a shake) after the workout.

So far it's been working for me. And I've been working out since I was a young teenager- some three dozen years now.

I have no background in science, and was totally sucked in by one of Gary Taubes' books precisely because of that. A lot of these authors are incredibly biased and happy to filter science to you in a way that's profitable for them. Volek and his Superstarch is someone I have little respect for. If you haven't come across it, and you're willing to listen to a different viewpoint, I really recommend http://carbsanity.blogspot.com Have a search for Attia, Taubes, Volek etc and you may find some surprises.
