Lipitor is a brand name for the drug atorvastatin, which is primarily used to lower cholesterol levels in the blood [1]. There is no evidence to suggest that Lipitor can be used to treat binge eating disorder, according to the sources provided. While some medications have been shown to be effective in treating eating disorders, such as antidepressants and antipsychotics, Lipitor is not one of them [2]. Additionally, a ketogenic diet has been suggested as a potential treatment for binge eating disorder, but this does not involve the use of Lipitor [3]. It is important to consult with a healthcare professional for proper diagnosis and treatment of binge eating disorder, as it can have serious physical and psychological consequences if left untreated.
