When you’re dieting to lose weight, human evolution is often working against you. We’ll talk about why with Daniel Lieberman, author of Fed Up and founder of Harvard’s Department of Evolutionary Biology. He spoke with Terry Gross about diets he’s tested, and the often contradictory information about what’s healthy to eat and what’s not.
Also, book critic Maureen Corrigan reviews Etna, a novel that looks at war through the narration of a dog.
