The reason it has been reviewed is that it was possible to buy it on Sunday 30th Dec and some people received it on Monday 31st Jan. I ordered it on Sunday too however thanks to the incompetent courier that was used, my copy is at some other address and not mine. I was told by Amazon customer service when I was tracking down what was happening that the book sold out (so no redelivery until next week) however Mimi (co writer) seems to think that it is a website issue...who knows. I wouldn't doubt the credibility of the reviewers ;)
We are both foodies, so find dieting really difficult, and miserable. This way of life (for that is what it is) works really well because we can be 'normal' on other days. We have lost 4 stone between us since August, and have never felt better. It's never too late because we are in our late 60s. It would be great if the obese amongst us would give it a go!
