My doctor had me on a low fat, sugar free /no sugar added diet that start 7 days prior to my surgery. This included yogart, milk, soups, jello, and puddings and I could have low fat crackers for the first 3 of those days, on day 4 no more crackers. Then the last day prior to surgery I had clear liquids only. Tea, Broth, Fruit Juice, Ices. , on this day I could have sugar to keep my energy up. The doctor stated the the reason for the fat free liquid diet was to shrink my liver. He explained that by shrinking the liver it made the surgery much easier to perform, he stated that they have to actually move your liver off your stomach to do the surgery and that the small it was the easier to move and that it was a very fragile organ so this really helped. I thought I would tell you what I did because there was a definite reason for it. Good Luck! Donna
