Childhood obesity has become a global crisis affecting over 400 million children. Yet many remain unaware of this silent emergency, and even fewer want to talk about it - until now.

This international investigation travels across Europe and the United States to expose the roots of the crisis, speaking to leading health experts and families living the reality first-hand, while conducting a shocking social experiment that reveals society's dangerous ignorance about what's really fuelling this epidemic. From predatory advertising and screen addiction to 'food deserts' in lower-income neighbourhoods and ultra-processed foods flooding school canteens, children are more vulnerable than ever to life-altering obesity-related health problems.

Faced with a crisis of global proportions, NBA-star-turned-food-activist Pau Gasol joins forces with the world's leading experts on nutrition and child health to tackle this overlooked pandemic and unveil the urgent solutions needed to save a generation.
