Eat Like the Animals is a must-read. This beautifully written book proposes a highly original and compelling explanation for why so many of us gain weight in today’s over­processed food environment. Raubenheimer and Simpson are biologists who use their deep knowledge of animal and insect physiology, evolution, and feeding behavior to construct a compelling hypothesis: We share with animals an innate appetite for protein that regulates what we eat.

At last a book on diet and nutrition that makes sense. In a world awash with misinforma­tion about what and when to eat, Eat Like the Animals is a breath of fresh air. I couldn’t put it down. Based on more than 30 years of cutting-edge research, it explains how the modern food environment hacks our hunger control system, then explains what we all should be eating to live healthily and age well.

Eat Like the Animals is a wonderfully clever and unusual introduction to the science of healthy eating. Full of drama, insight, and surprise, I love the way it is written. Rauben­heimer and Simpson make a very compelling case for the importance of protein in reg­ulating our hunger and very powerfully demonstrate the horrific role that the junk food industry has played in our lives. Essential reading.

Eat Like the Animals is quite simply a masterpiece. I am completely blown away by the science and enthralled by the clarity and elegance of the writing. Raubenheimer and Simpson have revealed the deep evolutionary secrets of the most important physiological need any animal faces by asking the right questions, and have eviscerated all the charla­tans, quacks, and pseudoscientists who seek fame and fortune by peddling rubbish. The story the authors have told is very important — more so than many people will realize.
