Synopsis

In this sweeping exploration of the relatively recent obesity epidemic, Michael L. Power and Jay Schulkin probe evolutionary biology, history, physiology, and medical science to uncover the causes of our growing girth. The unexpected answer? Our own evolutionary success. For most of the past few million years, our evolutionary ancestors' survival depended on being able to consume as much as possible when food was available and to store the excess energy for periods when it was scarce. In the developed world today, high-calorie foods are readily obtainable, yet the propensity to store fat is part of our species' heritage, leaving an increasing number of the world's people vulnerable to obesity. In an environment of abundant food, we are anatomically, physiologically, metabolically, and behaviorally programmed in a way that makes it difficult for us to avoid gaining weight. Power and Schulkin's engagingly argued book draws on popular examples and sound science to explain our expanding waistlines and to discuss the consequences of being overweight for different demographic groups. They review the various studies of human and animal fat use and storage, including those that examine fat deposition and metabolism in men and women; chronicle cultural differences in food procurement, preparation, and consumption; and consider the influence of sedentary occupations and lifestyles. A compelling and comprehensive examination of the causes and consequences of the obesity epidemic, The Evolution of Obesity offers fascinating insights into the question, Why are we getting fatter?

"Goes far beyond anything else that is available on obesity... Power and Schulkin deserve much credit for their bold attempt to combine evolutionary and reductionist explanations, and for their unflinching acknowledgment of complexity."Nature

"An excellent and comprehensive explanation for the increased incidence of obesity... Power and Schulkin suggest that there is a mismatch between our evolved biology and our modern lifethe advantages of fat storage in the past have become disadvantages today."New England Journal of Medicine

"Power and Schulkin look for the origins of obesity in our evolutionary past... They stress the complexity of obesity's origin and caution against simplistic solutions, especially biomedical therapies for obesity that often have unintended adverse effects."The Lancet

"A well written and scholarly tome with many fascinating observations and findings that highlight the many biological challenges to effective weight control in a modern society with a very efficient food delivery system. The breadth of scholarship is impressive and well documents in detail why humans are becoming obese."PsycCRITIQUES
