Based on the available information, there is no evidence to suggest that protein-rich diets are contraindicated with Lipitor (atorvastatin), a medication used to treat high cholesterol levels.

The first source, a webpage from Drug Patent Watch, does not provide any information about the relationship between protein-rich diets and Lipitor [${1}](https://www.drugpatentwatch.com/p/tradename/PROTEIN).

The second source, a scientific article from the National Institutes of Health's National Center for Biotechnology Information, discusses the effects of a high-protein diet on renal function, but does not mention any interactions with Lipitor or other statins [${2}](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10058246/).

The third source, the FDA-approved label for Lipitor, lists potential drug interactions, including other medications and grapefruit juice, but does not mention protein-rich diets as a contraindication [${3}](https://www.accessdata.fda.gov/drugsatfda_docs/label/2009/020702s056lbl.pdf).

It is always recommended to consult with a healthcare provider or a pharmacist for personalized advice regarding diet and medication interactions.
