Well, I start my pre-op diet tomorrow. My surgery is scheduled for the 18th. My pre -op diet will be 2 weeks. The first week I will have a protein drink for breakfast and lunch. I have isopure, which I think tastes awful and I have Nectar powder, strawberry mousse flavor.for only the first week, I can have 3-4 oz of chicken, turkey or fish without skin. It can't be fried. I also have a list of unlimited veggies I can have and a list fruit that I can only have 1 serving of. The 2nd week will only be 3 protein shakes and at least 64 oz water. The hard part is giving up my diet cokes, but it has to be done. I am ready to begin my new journey. Dr. Jeremy Korman, in marina del rey...ca, is doing my surgery.
