All cells in the body are designed to use fat for their primary energy except the nervous system (which is designed to use glucose as its primary fuel).
You can't absorb fats without bile. The liver makes 1 1/2 quarts of bile per day so it needs a storage tank. That is the function of your gall bladder.
The liver can't make bile fast enough to service a meal, so without a gall bladder, you will be deficient in fat to make cells and provide energy and the fat soluble vitamins. You must take supplemental bile(ox bile) with every meal the rest of your life if your gall bladder has been removed.
