De la contraportada

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.

"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 life—the 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
