I have only been following it for the last week so realise it's early days, but it is so easy. I really have eaten exactly what I want, twice in the last week I have felt hungry on the way home from work so I've bought a galaxy bar at the station and really enjoyed it, the best thing about it is because you are allowed to choose anything you want you don't feel guilty eating it. Before reading the book, I would eat a meal (especially dinner in the evening), get about half way though it and even though I was starting to feel full would clear the plate, afterwards I would feel so full I'd have no energy for the rest of the evening. I have yo-yo dieted for the last few years and have tried slimfast, slimming world and weight watchers and they all work for a while but then I give up and overall my weight has increased.
It really doesn't feel like I'm now on a diet and inbetween meals I am not thinking about food at all.
In a years time I hope to be able to say that reading Paul McKenna's book and applying the rule has changed my life.
Good luck.
