A Thorough Examination with Drs Chris and Xand

BBC Radio 4www.bbc.co.uk

Drs Chris and Xand van Tulleken investigate the science of exercise and the dangers of inactivity.

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? Most of us might like to get a bit fitter, but how easy is it to actually start exercising and give up sedentary habits?

In this series Drs Chris and Xand van Tulleken examine exercise and how best to do it. How much should we be doing? How does it help our bodies? And how does our surrounding environment stand in the way of us getting fitter? Chris is challenged to examine his scepticism towards exercise. Similarly, Xand is asked to look at his new-found exercise evangelism and see what he is really running from.

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 and a way to keep on top of things after years of unhealthy living.

His twin brother Chris, on the other hand, is really feeling the aches and pains of middle age. With a busy job and a young family, he has precious little spare time for exercise. After a very active period in his 20s and 30s, Chris 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?

S1. Ep 7 - One Year On

It’s been a year since Chris van Tulleken set his twin brother, Xand, a challenge to help him quit his addiction to junk food. Xand had to eat an 80% ultra-processed food (UPF) diet while learning about its health impact. It worked and by the end Xand rejected all those foods he’d previously adored, including his beloved Chinese dumplings. The experiment had an aversion effect, just as Chris had hoped. But something else happened during the experiment, Chris also had a conversion experience. A p...

It’s the main thing that we now eat and feed to our children, but most of us have never heard of it. It’s addictive, highly profitable and the main cause of the global obesity pandemic. It’s ...

Introducing A Thorough Examination

Chris van Tulleken is on a mission to get his twin, Xand, to quit ultra-processed food. There’s a growing global addiction to ultra-processed food aka UPF. Chris thinks UPF is driving Xand’s (and everyone else's) weight problem. So, he proposes a simple experiment - that Xand goes on a final week-long UPF binge whilst interviewing the world's leading experts on addiction, food, nutrition and weight. It's the nutritional equivalent of smoking 100 cigarettes whilst going on a quit smoking course. ...
