Daily diet and calorie targets

Today we’re exploring one of the most ambitious self-experiments in human history.

Entrepreneur Bryan Johnson has spent over $2 million in an attempt to slow - or even stop - the ageing process. From diet and supplements to sleep and skin care, every part of his life is measured, analysed and optimised.

I’m joined by Professor Tim Spector to dissect Bryan’s data-driven diet, discuss the future of personalised health, and hear Bryan’s top five tips for a better night’s sleep.
