As obesity increases at a relentless pace, so does its negative effects on health. Campaigns and initiatives launched all around the world on the problem of obesity have proved futile, and the challenge to get rid of those unwanted kilos has turned into an endless nightmare. So, what exactly are we doing wrong? What's the mistake we're making? Findings from studies conducted in recent years suggest a new and promising perspective based around one central idea: what if the key to obesity is not to be found in the stomach but in the brain? In our quest to find answers to these and other questions, this book takes us on a fascinating trip through the different scientific disciplines related to the brain and nutrition, such as endocrinology, neurology, psychology and psychiatry. How does the brain control the intake of energy? Why do we sometimes eat without needing to? Can we become addicted to foods? What impact does food marketing have on us? And can we change bad habits and lose weight? "A book that, without doubt, I would have liked to have written myself". Juan Revenga, dietitian and biologist.
