Lipitor is a drug that is used to lower cholesterol levels in the body. According to Drug Patent Watch [1], Lipitor is a member of the statin class of drugs and is one of the most widely prescribed drugs in the world. However, there is no evidence to suggest that Lipitor leads to obesity.

In fact, a study published in the National Library of Medicine [2] found that there was no significant difference in weight gain between those taking Lipitor and those taking a placebo. The study also found that there was no significant difference in body mass index (BMI) between the two groups.

While some drugs have been linked to weight gain, Lipitor is not one of them. As Forbes [3] points out, there has been a long search for a drug that can treat obesity in the same way that Lipitor treats high cholesterol. However, no such drug has been found yet.

In conclusion, Lipitor does not lead to obesity. While some drugs have been linked to weight gain, Lipitor is not one of them. It is important to consult with a healthcare provider before starting any new medication.
