He’s become the academic poster boy of the intermittent fasting movement. Professor Valter Longo’s work on how the human body behaves when we deprive it of energy has inspired a range of diet books (including his own).

Valter Longo's book The Longevity Diet is published by Penguin (ISBN: 1405933941).
