Does nature want us to be fat?

For years, Richard Johnson, MD, professor of renal medicine in the Division of Renal Diseases and Hypertension at the University of Colorado School of Medicine, has investigated the impact of sugar, especially fructose, on the human body and how we process it. He recently published “Nature Wants Us to be Fat,” a book outlining why evolution has programmed us to overeat on the promise that we will lose the weight during lean times.
