Today is an absolute cracker of a podcast and critical listening for anyone who eats food and wants to avoid weight gain, Type 2 diabetes and Alzheimer's disease!

Professor Richard Johnson is the Tomas Berl Professor of Medicine, and Chief of the Division of Renal Diseases and Hypertension at the University of Colorado Denver.   He is board certified in internal medicine, infectious diseases, and kidney disease and is the founding editor of Comprehensive Clinical Nephrology, one of the main textbooks on kidney disease. For more than 20 years, he has led research on the cause of obesity and diabetes, with special interest in the role of sugar (especially fructose) and uric acid. His research has been highly cited, published in top medical journals, and supported by grants from the National Institutes of Health. He is the author of the books Nature Wants Us To Be Fat, The Sugar Fix and The Fat Switch.

His body of work presents convincing evidence that obesity, diabtes and Alzheimer's disease are triggered by a “switch” in our metabolism that makes us want to eat more and exercise less.
