Exponential Weight Loss

A Tennessee native with a PhD from Cambridge University, Nathan Dean has spent years building mathematical models of physical processes. While modeling the behavior of subnuclear particles as a physics professor at Iowa State University, he lost weight after he began running; so he decided to build a mathematical model of that process as well. He found that each additional daily mile resulted in a loss of about five percent of body weight. For many years afterward, while his daily running distance varied, his model accurately described how his weight changed with it. Based on that success, he extended the model to describe how weight loss results from dieting. To his surprise, he found that the severe calorie reduction of commercial diet plans is counter-productive. A small reduction in daily calorie intake is all that's required for a significant weight loss. But it's a slow process - an exponential decrease over a couple of years of about a pound for every fifteen calories. And, as with running, his own body verified that prediction. The result of that discovery is this book, in which he shares a fundamentally new approach to weight control. Now retired from a career as a university professor, dean, and vice president, he is an avid fine art photographer, living with his wife Mary in Atlanta, Georgia.
