But then, having read his latest book, I actually know an awful lot about his diet. How he doesn’t eat sugar, any fruits which “don’t have a Greek or Hebrew name” or any liquid which is less than 1,000 years old. …..

He makes me order tiramisu and then eats half of it, but then no food has passed his lips for about 17 hours, he says. Incorporating randomness into his life has led him to adopt the style of eating known as “paleo”. Roughly speaking, this means that if a caveman wouldn’t have eaten it, then you don’t.
