Well, I've had a quick glance through the first few chapters and a lot of it makes sense. He is saying that to lose weight we need to follow four golden rules:
1. Eat whenever you are hungry.
2. Eat only what you want, never what you think you 'should'.
3. Eat consciously and enjoy every mouthful (the most important rule).
4. Stop when you even think your body is full.
He says this is how 'normal', thin people eat, so he argues that if we learn to eat like thin people, we will eventually become thin people. He gives a lot of tips like: chew every mouthful thoroughly, concentrate on enjoying each mouthful, and put your fork down until you have finished eating the current mouthful. I broke my diet and had some chocolate yesterday, but instead of really enjoying it, I wolfed it down as if I was starving and someone was about to take it away from me. I can't say I got a lot of pleasure out of my bar of chocolate. If I had been following his tips, at least I would have enjoyed it a bit more.
I don't really fancy being hypnotised by his CD but I will read the book and see what else he has to say.
