Lipitor is a brand name for atorvastatin, which is a type of medication known as a statin. Statins are prescribed to lower cholesterol levels in the blood, which can reduce the risk of heart disease and stroke [2]. According to the British Heart Foundation, statins work by blocking the action of an enzyme in the liver that produces cholesterol [2]. Lipitor has been shown to be effective in reducing LDL or "bad" cholesterol levels by up to 60% [2].

While Lipitor can be effective in reducing cholesterol levels, it is not a license to consume high-fat foods. According to a study published in the Journal of Clinical Lipidology, a diet high in saturated fat can reduce the effectiveness of statins like Lipitor [3]. The study found that participants who consumed a high-fat diet had higher levels of LDL cholesterol, despite taking statins [3].

Therefore, it is important to maintain a healthy diet and lifestyle while taking Lipitor. The British Heart Foundation recommends a diet that is low in saturated and trans fats, high in fruits, vegetables, and whole grains, and includes lean protein sources such as fish and poultry [2]. Regular exercise and not smoking are also important for maintaining heart health [2].

In conclusion, Lipitor can be effective in reducing cholesterol levels, but it is not a substitute for a healthy diet and lifestyle. A diet high in saturated fat can reduce the effectiveness of statins like Lipitor, so it is important to maintain a healthy diet and lifestyle while taking this medication [2][3].
