I disagree. A Water Fast is not the same thing as optifast. On a water fast, all you put into your body is water. Optifast uses shakes as meal replacements. I personally feel that when it comes to weight loss, everyone takes their own journey and everyone has to find what works and what doesn't work for them. Everything will work for some, but not others. I believe that whether or not lbs. were gained back, it's a wonderful thing that 54 lbs. were lost to begin with.
