I've tried them all. This is the best detox out there - it is actually possible to stick to, for a start, though I too, as did other reviewers , did it in a week off work - it is very time consuming, and this would be where it'd be easy to fall off, if you didn't have the time. In addition, the juices are yummy - I skipped the horrible one - and you KNOW it's good for you. I did it over a month ago and I still have a juice for breakfast. I can't see how you could go back to eating rubbish after doing this. I didn't weigh myself, and I don't believe anything you do for 7 days can be claimed to do anything of substance for your weight - but as a detox and an ingraining of healthy habits, it is Fabulous!
