Hi, My name is Gwen. I lost 27 pounds in 21 days on the Martha's Vineyard diet. I feel absolutely great. I thank the good lord for this diet everyday. I have been obese for so long and this diet is saving my life. I am in the second round of 21 days and I have now lost a total of 50 lbs. I took a break in between for 2 weeks. I was anxoius to start again before the holidays. You must follow the book word for word exactly as precribed. But you will loose the weight if you do. The diet is a little expensive and time consuming but it is worth the effort.
