Our #1 podcast series with Drs Chris & Xand van Tulleken”

Chris and Xand are doctors, scientists, identical twins and hosts of our award-winning (not to mention life-changing) A Thorough Examination podcast.

Series one, Addicted to Food: Chris wants Xand to quit UPF and lose the 20kg weight difference between them. He sends his brother on a journey to meet leading experts on food, weight, taste and addiction whilst encouraging a final UPF binge to see if Xand can learn to hate it. It turns out to be far stranger and more emotional than either of them could imagine…

Series two, Can I Change?: Chris thinks he and Xand argue too much and is determined to improve his relationship with his brother but Xand is less convinced this is possible or that he needs to change. Chris confronts that pessimism. The twins consult with professors of cognitive neuroscience, geneticists, psychologists as well as their own family.

Series three, Exercise: Is modern exercise a wellness cult? Or is it a vital cure for a world that’s struggling with ill health and stuck on the sofa? Recently Xand has discovered the joys of physical activity. He’s running, cycling, heading to the gym and playing ping pong like never before. It’s been a real transformation. His twin brother Chris, on the other hand, is now embracing his ‘Dad bod’ and sliding into a creaky middle age. Xand wants to help him turn things around. Can he do it?

A Thorough Examination with Drs Chris and Xand is now available on BBC Sounds.
