Lipitor is a brand name for the drug atorvastatin, which is a type of statin used to lower cholesterol levels in the blood [1]. Statins, in general, have been associated with an increased risk of developing diabetes, although the mechanism behind this is not yet fully understood [2].

There is no evidence to suggest that Lipitor decreases sugar cravings. However, it is worth noting that sugar cravings can be caused by a variety of factors, including hormonal imbalances, stress, and nutrient deficiencies [3]. It is important to address the root cause of sugar cravings rather than relying on medication to alleviate symptoms.

In summary, Lipitor is a medication used to lower cholesterol levels, and while it has been associated with an increased risk of developing diabetes, there is no evidence to suggest that it decreases sugar cravings. It is important to address the underlying causes of sugar cravings rather than relying on medication to alleviate symptoms.
