Diet before the sleeve??
It depends on your surgeon and/or your insurance. Alsoyour you are super heavy, some surgeons will require you to lose some weight that they would not otherwise require. It is advisable to lose weight before surgery to shrink your liver which makes the surgery go smoother. Otherwise, you will have a fatty liver. I was not required to do any diet before surgery, other than 2 days pre-op of a liquid diet. But it was recommended that I lose some weight before hand.
