The Fats of Life

Fat is an issue talked about frequently in both magazines and academic journals, but this is the first accessible account for the general reader written by an acknowledged expert biologist. With examples from across the animal kingdom, Caroline Pond engages the reader with the truth behind the speculation.

This book aims to fill the gap between unscientific comments about the hazards and benefits of high-fat or low-fat diets and weight control found in magazines and technical and medical reports about lipid biochemistry and obesity. It aims to explain in simple language the biology of feeding and fasting, fattening and slimming in wild animals as well as people. Topics include where fat comes from and how animals and plants handle them, their natural roles in migration, mating breeding and living in unpredictable habitats such as deserts and arctic regions, and their contributions to our cookery, paints and medicines. The physiological mechanisms of digesting, transporting and utilising energy stores are discussed, along with the contribution of fatty tissue to body insulation and the protection of delicate organs. Archaeological, anthropological and physiological evidence is assembled to explore how, when and why people have become fat, and how evolutionary forces have determined the modern diversity of body shape and size. The book ends with a brief account of the contribution of dietary fats and obesity to health in the modern world.
