Hi jdhssh, I'm not sure who has been giving you that information but it's obviously not anyone that has read Dr. Atkins book! Have you read the book yourself? If not I strongly suggest you do as it will give you a lot of necessary background information and answer any uncertainties that you may have about the diet. Just for the record, going off the diet for two days after every week is definitely not a good idea, it will just ruin all of the hard work you have put in over the seven days.
