Lipitor is a medication that is used to lower cholesterol levels in the body [1]. It works by inhibiting an enzyme called HMG-CoA reductase, which is responsible for the production of cholesterol in the liver. By inhibiting this enzyme, Lipitor reduces the amount of cholesterol that is produced in the liver, leading to lower levels of cholesterol in the blood.

Regarding the effect of Lipitor on dietary fat intake, the sources do not provide direct information on this topic. However, it is important to note that dietary fat intake can affect the effectiveness of Lipitor in reducing cholesterol levels. A study published in the Journal of Clinical Lipidology found that a diet high in saturated fat can reduce the effectiveness of Lipitor in lowering LDL cholesterol levels [3]. Therefore, it is recommended that individuals taking Lipitor follow a healthy diet that is low in saturated and trans fats, and high in fruits, vegetables, and whole grains [2].

In conclusion, Lipitor works by inhibiting the production of cholesterol in the liver, leading to lower levels of cholesterol in the blood. While the sources do not provide direct information on the effect of Lipitor on dietary fat intake, it is important for individuals taking Lipitor to follow a healthy diet that is low in saturated and trans fats to maximize its effectiveness in reducing cholesterol levels.
