from What's My Age Again?

There’s a new take on things for this episode as Katherine welcomes Tim Spector onto the podcast – the first guest who is no stranger to the Glycanage blood test. Tim has been tracking his biological age for several years, so there is more data to discuss with Dr Nichola, as they delve into how his internal age has changed over time and the various things he was doing to shift the needle.  With Tim’s new book Ferment: The Life-Changing Power of Microbes out now in all good bookshops, expect to hear all the latest science about our gut microbiomes, Tim’s predictions for wellness trends, and more personal stories about how he recovered from a health episode in 2012 and how a fast food experiment with his son had a lasting impact on his son’s microbiome.   Listen now to find out how Tim’s biological age reflects his knowledge and advocacy and hear what he has to say about how your diet could impact your biological age.
