I am on a high protine pre-op diet that is intended to help deplete the liver of its glycogen stores prior to the operation to help shrink the liver. It consist of 1000 calories a day, 100 grams of protein a day, and 2 quarts of water. They have me drinking five 8oz bottles of Slimfast high protein drinks and a combination of hardboiled eggs, yogurt, and cottage cheese to equal 100 grams of protein. That is the diet they have me on right up to my surgery. Is anyone else on that type of prep diet? It doesent sound like it and I havent had any of the symptoms people on the liquid pre-op diet have described in other forums here. I feel full all the time and almost have a difficult time eating everything I am supposed to each day. I am on my 3rd day of my prep for surgery on the 14th Dec.
