In the interest of science, Daniel Lieberman has put himself through the mill. The Harvard professor of human evolutionary biology has tried and documented what it was like to practice the raw food and paleo diets, drinking shakes instead of eating, the low-carb high protein Atkins diet, intermittent fasting, and the Mediterranean diet.  

He joins Jim to talk about his book Fed Up: What Evolution Reveals about Food, Diet and Eating Well, and how he felt when he was trialling the different food regimes.
