Lipitor is a medication that is primarily used to lower cholesterol levels in the body. However, it is not intended or approved for weight loss purposes. In fact, weight gain is listed as a possible side effect of taking Lipitor [1].

Lipitor works by blocking an enzyme in the liver that is responsible for producing cholesterol. By reducing the amount of cholesterol in the body, Lipitor can help prevent the buildup of plaque in the arteries and lower the risk of heart attack and stroke [2].

While weight loss is not a direct effect of Lipitor, some studies have suggested that there may be a correlation between taking Lipitor and losing weight. One study found that overweight and obese individuals who took Lipitor for six months lost an average of 6.4 pounds [3]. However, the study was small and more research is needed to confirm these findings.

It is important to note that Lipitor should only be taken under the supervision of a healthcare provider and for the intended purpose of lowering cholesterol levels. It is not a weight loss medication and should not be used as such.
