Based on the available information, Lipitor does not completely inhibit fat absorption in the body. Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels [1][2]. It works by inhibiting HMG-CoA reductase, an enzyme that plays a crucial role in the production of cholesterol in the body [2].

However, Lipitor does not directly affect the absorption of fats from food in the digestive system. Dietary fats are absorbed in the small intestine through a process that is separate from cholesterol production [3]. Therefore, Lipitor's mechanism of action is unrelated to fat absorption.

In summary, while Lipitor is an effective medication for lowering cholesterol levels, it does not inhibit the absorption of fats in the body.
