The acme of diet books.
Tried every diet under the sun - and failed. Been on this one since the HB first appeared (Jan '07) and to date (17th Jul '08) have lost 12st 4lbs.
OK, the 'everything free-range/organic' is fine if you have the salary of a Sunday Times A-Lister but it can be adapted...
The whole psychology of fatness preamble is stunningly well written and certainly appears to have done the trick for me.
Warning: Stick with it for a year and half the world will want to know exactly how it's done...
