I agree with the reviewer from Virginia. This diet is horrible! And, as for the reviews being fixed - they are... I suggest the Sunzanne Sommers book- it is smart eating, I lost 4 lbs. in the first week without even noticing I was on a diet. The Atkins book is great but once you are off the diet you will gain weight because the carb. intake is too restrictive. If all else fails, excercise and drink plenty of COLD water- it works!
