Why Are We Fat?

Obesity is the biggest health crisis on the planet. For the first time in history children are facing shorter lives than their parents. Presented by overweight and diabetic Chef Simon Gault, this series examines the science behind a re-examination of traditionally accepted health advice and the emergence of new evidence that at last makes sense of the looming health problems we face. Simon talks to experts from around the world and allows himself to be a human guinea-pig in an attempt to improve his own health.
