Michael Mosley meets Professor Mark Mattson. His work with mice at the National Institue on Ageing, has produced some startlig results about diet and memory.

Michael Mosley has set himself a truly ambitious goal: he wants to live longer, stay younger and lose weight in the bargain. And he wants to make as few changes to his life as possible along the way. He discovers the powerful new science behind the ancient idea of fasting, and he thinks he’s found a way of doing it that still allows him to enjoy his food. Michael tests out the science of fasting on himself – with life-changing results.
