I have seen this and have sample a copy of the book. I think most of what is within is pretty obvious. It does help to aid your thinking though and to get your mind around how you should be seeing yourself and food.
In all fairness from what I remember it was rather expensive and I didnt feel it was worth the money.
I had to google it too, and at first glance it just looks like yet another person trying to make money out of stating the obvious? And I can think of similar "systems" and books for a fraction of the cost?
I think I'm missing the point of it, can anyone explain what it really is in any more detail? And how the flip it could be worth £80?
