What causes the fat around the liver to go away is it the lack of meat? Or carbs? or sugar?

losing weight decreases the fat around organs.

The liver stores carbohydrate in the form of glycogen. When carbohydrate is restricted, the body draws on this store for energy.

Yes, fat is also lost with weight loss. But that's not what the preop diet is all about. It's about depleting glycogen stores.

My doctor told me that the reason why I have to have a 2 week liquid diet is to shrink my liver...

Search ketosis on google.

Your liver holds the body's short term energy resources that, if we were still hunting for our food, would see us through those no food days. It depletes fairly quickly, causing the liver to shrink. A lot of the pre-op weight loss is actually Water loss from the liver, not real weight.

The pre-op diet is simulating the famine time. After the surgery when you start eating carbohydrates and sugars again, expect your liver to plump up again, and expect that you may gain weight as your liver stores lost water.

ON day one of the liquid diet and wondering too what exactly shrinks the liver? I'm drinking juices which are high in natural sugars and therefore carbs.

Yeah, that's not going to do it. I was strictly banned from all fruit juices during the pre-op diet. Even natural sugars are sugars. As much as aspartame isn't the best stuff in the world to survive on, it is your friend during this time. Embrace the Crystal Light. Kool-Aid also makes an excellent sugar free grape.

To get the liver to give up the goods, you have to starve it of all quick fixes of energy... carbs and sugars. Whether or not they're natural is irrelevant. Wave bye bye to fruit too. Protein is harder to digest and is therefore not a quick fix.

I'm a bit of a special snowflake in that I'm allergic to ALL the Protein shakes. Vegan, lactose-free, soy-free, I've tried them all. My pre-op diet had to include actual food as I couldn't very well not eat for three weeks. I ate a truckload of plain chicken, plain fish and veggies. I missed fruit like you wouldn't believe! All the tea in the world I could drink but no honey or sugar in it for sure. I drank truckloads of Crystal Light. I should buy shares in Crystal Light.
