I started off strong with the pre op diet consisting of the 3-4 protein shakes per day. I had lost a total of 16lbs sticking to the diet. However I went off the diet and gained 10lbs back. I had no idea that if you gained any of the weight back you would be required to start over. So now I have till August 1st to lose the required 10lbs or I can not keep my surgery date of August 30th. If anybody has any advice I would greatly appreciate it.
