Preop Liquid Diet????
I think it has to do with shrinking and firming your liver so it is easier for them to work. I have a surgeon that use to adhere to that but he says now it is not got to be ALL LIQUID just no fat and such that would make your liver stay enlarged. (which I didn't know they did anyway). Hopes that helps.
I did the pre-op liquid diet for two weeks and I'm happy I did ! I loss 16 lbs in 9 days on it. I had been doing low-carb diet since Feb and walking a lot. I loss 20 lbs doing that, took 6 months THEN by doing the liquid diet for TWO weeks before surgery and walking, I loss another 20 lbs! so I dropped 40 lbs before surgery to get my body in good shape for the surgery. I had NO Pain at all from the surgery! (my back really hurt, though). I went to sleep at 11:30-12:00 at night in the hospital and up walking the halls by 4:30a.m. or 6:00a.m. I tried to walk every hour all day long. I JUST HAD SURGERY FIVE DAYS AGO > STILL NO PAIN> WAS AT HOSPITAL THREE DAYS
