Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels and reduce the risk of heart disease [1]. According to the Mayo Clinic, some of the common side effects of atorvastatin include headache, muscle aches, joint pain, diarrhea, and nausea [3]. However, the sources provided do not suggest that atorvastatin can contribute to belly fat.

One study published in the Journal of Clinical Lipidology found that atorvastatin did not significantly affect body weight or body mass index (BMI) in patients with high cholesterol levels [2]. The study also reported that atorvastatin did not increase the risk of developing diabetes or metabolic syndrome, which are conditions that can contribute to weight gain and belly fat.

While weight gain is a possible side effect of some medications, including some types of antidepressants and antipsychotics, there is no evidence to suggest that atorvastatin contributes to belly fat. It is important to talk to a healthcare provider if you have concerns about the side effects of any medication, including atorvastatin.
