Humans evolved eating animal fats, so our bodies work best with them—not plant oils.
Scientific Claim
Human evolutionary physiology is adapted to metabolize and utilize animal-derived saturated and monounsaturated fats as primary dietary lipids.
Original Statement
“The main type of fat humans consumed was animal fats. This is what makes them so great. They are the only fat that humans are biologically adapted to.”

Dietary Fats and Cardio-Metabolic Outcomes in a Cohort of Italian Adults
This study found that people who ate more animal fats like butter and meat didn’t have more heart problems or diabetes — in fact, they had fewer. This suggests our bodies are built to handle these fats well.
This study shows that our ancestors evolved to efficiently use fats from meat as their main energy source, and our bodies still have the tools to do so — meaning the claim is backed up by science.
