Lipitor is a prescription medication that belongs to a group of drugs known as statins. It is used to lower cholesterol levels in the blood and reduce the risk of heart disease [1]. Statins work by inhibiting an enzyme that produces cholesterol in the liver, thus lowering the amount of cholesterol in the blood [2].

According to the British Heart Foundation, there are no specific dietary restrictions when taking statins like Lipitor. However, it is recommended to follow a healthy and balanced diet that is low in saturated and trans fats, as well as high in fruits, vegetables, and whole grains [2]. This is because a diet high in saturated and trans fats can increase cholesterol levels in the blood, which may counteract the effects of Lipitor.

In general, it is advisable to avoid high-fat meals when taking Lipitor, as this can interfere with the drug's effectiveness. A study published in the Journal of Clinical Lipidology found that consuming a high-fat meal within four hours of taking a statin like Lipitor can reduce its absorption by up to 50% [3]. Therefore, it is recommended to wait at least four hours after taking Lipitor before consuming a high-fat meal.

It is worth noting that some people follow a high-fat diet, such as the ketogenic diet, for various reasons, including weight loss and improved blood sugar control. However, a cardiologist interviewed by Penn Medicine cautions that this type of diet may not be suitable for everyone, especially those with a history of heart disease or high cholesterol levels [4]. Therefore, it is important to consult with a healthcare professional before making any significant changes to your diet or lifestyle.
