I just saw this plan yesterday. It seems way too strick to me also.
It's probably a healthy way to eat, if you can stick to it
One of the things that struck me is that he said a banana has 22 grams of sugar, so they are off the plan. Blackberries were only 5g (I think), so they were ok.
He has several videos on his website and in one he was going on about how diets don't work--but he's come out with this "diet"--funny
