Based on the information available, there is no direct correlation or clinically proven timeline between taking Lipitor, a cholesterol-lowering drug, and weight loss. Lipitor, also known as Atorvastatin, is primarily used to treat high cholesterol and triglyceride levels in the blood [1].

The misconception might arise from the fact that some cholesterol-lowering drugs, including statins like Lipitor, can have side effects that include decreased appetite and digestive problems such as diarrhea, nausea, and constipation [1]. These side effects might indirectly lead to weight loss in some individuals. However, this weight loss would not be a direct result of Lipitor's intended function, and the impact on weight would likely be minimal and vary greatly from person to person.

It is important to note that Lipitor is not indicated or approved for weight loss purposes. Any significant weight loss while taking Lipitor should be reported to a healthcare professional, as it may be a sign of underlying issues or side effects.
