According to the sources provided, there is no clear evidence to suggest that Lipitor (atorvastatin) can increase abdominal fat. Lipitor is a medication used to lower cholesterol levels in the blood, and it works by blocking an enzyme that produces cholesterol in the liver [1]. While Lipitor can cause side effects, such as muscle pain, weakness, and liver problems, abdominal fat is not listed as a known side effect [3].

A study published in the Journal of Clinical Endocrinology and Metabolism examined the effects of atorvastatin on body composition and found that it did not increase abdominal fat [2]. The study involved 80 participants who were randomized to receive either atorvastatin or a placebo for six months. The researchers measured changes in body composition using dual-energy X-ray absorptiometry (DXA) and found no significant differences in abdominal fat between the two groups.

It is important to note that everyone's body responds differently to medications, and some people may experience side effects that are not listed in the official prescribing information. If you are concerned about changes in your body composition while taking Lipitor, it is recommended that you speak with your healthcare provider.
