Which specific animal fats are suggested for pan-frying catfish carnivore-style?

Rendered beef tallow or lard.

When preparing catfish in a manner suitable for the carnivore diet, the cooking medium must also be animal-derived. Instead of utilizing vegetable oils, which are excluded, adherents are advised to use rendered animal fats. Specifically mentioned compliant options include melting a generous amount of rendered beef tallow or lard in a pan over medium-high heat. Searing the seasoned catfish directly in this hot animal fat ensures that the energy source consumed during the meal remains strictly within the boundaries of animal products.
