If you've got Netflix, give the Magic Pill a watch. There's some interesting stuff on there about it, from obese women who are hammering medications, to autistic children, to a massive court case in South Africa. It covers numerous things and has some of the top nutritionists talking about it and claiming that the nutritional advice we've been given over the years from botched evidence and research is now probably wrong.
For me, I'm convinced this is the lifestyle I should be leading now. It's not for everyone, but I do think a majority that do it feel the same.
