Eat Like the Animals: What Nature Teaches Us About the Science of Healthy Eating by David Raubenheimer and Stephen J. Simpson is a science-based exploration of nutrition, appetite, evolution, and healthy eating. Drawing on decades of research in nutritional ecology, the authors investigate how animals instinctively balance their intake of nutrients—and what humans can learn from them.

The book introduces the authors' influential concept of protein leverage, examining how the body's appetite for protein can influence food consumption. Through examples involving locusts, baboons, gorillas, mice, yaks, and other animals, the authors explore how different species regulate their diets and why modern humans can struggle to maintain nutritional balance in an environment dominated by highly processed foods.

Combining evolutionary biology, nutritional science, appetite research, metabolism, and public-health perspectives, the book explains why certain foods can encourage overeating and how understanding the body's nutritional priorities may help people make more informed dietary choices. It also challenges simplistic fad-diet approaches and offers practical ideas for improving the modern food environment.
