I am scheduled for June 10th. My insurance also had called for 6 months of a medical supervised diet. My Dr. Has a nutritionist in his office. So I went there. They told me right off they didn't expect you to lose to much weight during the 6 months. But, they get you prepared on how you will be eating after the surgey. As sop as I had my 6th visit they gave me my surgery date, which is approx a month from my last nutrition vist.
