287: Daniel Lieberman: Evolution and the Human Diet
Summary
Daniel Lieberman discusses his book *Fed Up*, arguing that an evolutionary perspective offers a nuanced approach to diet and exercise beyond simplistic trends like the Paleo diet. He traces human dietary evolution from frugivorous ancestors to *Homo erectus*, explaining how cooking and meat consumption enabled brain expansion. Lieberman critiques the "naturalistic fallacy," emphasizing that humans evolved to eat diverse, locally available foods rather than a single ancestral diet.
