Weight loss is not typically listed as a common side effect of taking Lipitor (atorvastatin), a medication used to treat high cholesterol, when following a low-fat diet. Lipitor works by reducing the production of cholesterol in the body, which can help prevent heart disease and stroke [1].

The most common side effects of Lipitor include diarrhea, upset stomach, muscle and joint pain, and changes in liver enzymes [1]. Weight loss is not mentioned as a common side effect in the drug's prescribing information or in clinical trials [1][2].

However, it is important to note that everyone's body reacts differently to medication, and some people may experience unexpected side effects. If you are taking Lipitor and notice a significant change in your weight, it is recommended to speak with your healthcare provider [1].

In summary, weight loss is not a commonly reported side effect of taking Lipitor while on a low-fat diet. The most common side effects include diarrhea, upset stomach, muscle and joint pain, and changes in liver enzymes. If you experience any unexpected side effects while taking Lipitor, it is important to speak with your healthcare provider.
