fimble, ASM will come and answer this, but I just wanted to say that the idea of PMK and indeed and HT for weightloss I think, is that you eat as and when you are hungry. PMK has some healthy principles in his books, about drinking water and taking exercise, but it's also important not to deprive yourself, which leads us to think about food even more, and thus, put so much importance on the damn stuff! So as far as I've understood from reading the book and listening to the CD, there are 4 principles.
You need to eat when you are hungry - so drink some water to see if it's really thirst, sure, but if you are hungry EAT.
Eat what you want, not what you think you should - if you want some chocolate, have some! But remember you only need enough to satisfy.
Eat consciously, enjoying every mouthful - this will help you to eat more slowly and register when you are full, which takes around 20 minutes.
Stop when you even think you are full.
On the point about eating what you want, I have been doing that but have actually found I have naturally not wanted the chocolate. The freedom and confidence to eat what I want and when I need it, has allowed me to drop the obsession with, say, going into a shop for a mag and coming out with a family sized bar of choc and eating it in the car on the way home.
My WHOLE attitude has changed, and I am not joking. But as the OP said a few posts ago, people scoff at it, so I don't usually broadcast the fact I have had HT. Seeing this thread and the OP's amazing success, just made me feel even more confident and overwhelmed with the thought that HT is actually going to work for me!
