A New Scientist Best Book of 2020

How is it that a baboon and a blob of slime mould instinctively know what to eat for optimal health, balancing their protein, fat and carb intake in perfect proportions?

In new, groundbreaking research that is transforming our understanding of nutrition, animals from locusts to lions and yes, humans too, demonstrate the remarkable science behind appetite.

Appetite communicates the body's nutritional needs to the brain, and eating in accordance with your body's demands, like the animals, should ensure optimal health, but the modern fast food world wreaks havoc on this evolutionarily honed system.

In several landmark studies, Raubenheimer and Simpson prove that appetite can be hacked – we can eat for optimal health, for increased fertility or for a longer lifespan. Understanding the science of the appetite offers tremendous power in shaping our bodies and controlling our lives.
