Daniel Lieberman

DANIEL LIEBERMAN, author of the new book Fed Up: What Evolution Reveals about Food, Diet, Health and Eating Well. He’s a professor of biological Sciences at Harvard. And he's the founding chair of Harvard's Department of Human Evolutionary Biology. As part of his research, he tried a series of diets to see how his body reacted, including the Atkins diet and lesser known diets like the Blue Zone diet. (THIS INTERVIEW CONTINUES INTO THE SECOND HALF OF THE SHOW).

Daniel Lieberman is a professor in the department of human evolutionary biology at Harvard. He says that the notion of "getting exercise" — movement just for movement's sake — is a relatively new phenomenon in human history. His new book is Exercised: Why Something We Never Evolved to Do Is Healthy and Rewarding.

In The Story of the Human Body, evolutionary biologist Daniel Lieberman explains how our bodies haven't adapted to modern conditions. The result is "mismatch diseases" -- ailments that occur because our bodies weren't designed for the environments in which we now live.
