Ok this is from what i remember from a few rusty brains cells!

Your liver stores a backup energy store of energy in the form of Glycogen.

When you eat food it goes down into your stomach where it starts to be proccessed into the large intestine, this is where the Pancreas comes. If carbs are detected then it will secrete some insulin so cells can utilize the consumed food being put into the blood stream. (The basis for the post workout carbs theory)

When no carbs are detected or no food is present (starvation) The Pancreas will secrete Glucagon which will go to the liver and convert the stored Glycogen into usable carbohydrates for the body to use.

So when people loose lots of weight the first week on a starvation or Low carb diet this is the result of Glycogen depletion in the liver and muscles. Stored carbohydrates is another reason why it takes 3-4 days to get into ketosis.

Hope this makes sense...if not im sure Wikipedia can elaborate on it ;-)
