Lisa,
I have been am on the liquid diet for two weeks. I have been told the diet does shrink the liver but it also gets you ready for your new diet after the surgery.
I have heard some doc's do request it and some don't, I am telling you , now , I love my doctor ( Melkonian ) BUT .... this has been so hard for me I would maybe would have gone to a doctor who did not require it , I know some may be mad at me for saying this but , honest THIS DIET SUCKS

I know it will in the end be well worth it , and I only have today and tomorrow to deal with as my surgery is on Tuesday , and I will tell you now , if this diet shrinks the liver, mine should be the size of a pea

My girlfriend who is a doctor told me yesterday , fat around the liver is burnt quickly when the body is without fat intake, and also the intestine and bowel get a super rest when you are liquids and it prepares them for the trauma of surgery. ( it is great having a best girlfriend since 5th grade become a doctor , you get all kinds of advice free, THANKS Judy ) ... anyways, the liquids are on for me , and I will admit I am a smoothie expert now.
Happy Sunday to you and All, Take care .
