Query: not exactly one day...

This is one of those books that sound too good to be true, and is too good to be true. The cover makes promises the context can't keep. There's a seven day "prequel" of very restircted eating, the "one day detox" of just juice, and a three day sequel of very restricted eating, all to be followed with serious dietary changes for life. If it was easy for people to eat like this they would already be doing it and they wouldn't need this book. There's a lot of good nutritional information here (although she said vinegar makes you acidic, when, even though it is acidic, it makes you alkaline when metabolized, which is what you want if yu want to be healthy). Bottom line is, if you need to lose 10 lbs quickly, can stick to a tough regimine for 10 days, and don't mind gaining the weight back when you go back to your regular eating habits, this book is for you.
