Good luck mate. It sounds like a nonsense diet to me, just someone trying to come up with yet another twist and unique angle to sell a book. But as your problem is clearly psychological in nature if it motivates you it may well work for you.

I actually think you don't need diet advice whatsoever though. You surely know what the healthy foodstuffs are and what you should not be eating, the problem lies in applying it.

I think you need to tackle the root cause, which is a behavioural disorder rather than embarking on another diet.

I would really recommend this book. It's what I used to get me on my exercise program, and Ive stayed on it for 7 months now. Really helpful book about changing ingrained behaviour patterns effortlessly. It's a great book and has some usual studies on overeating in there too.
