Renowned twin doctors, Chris and Xand van Tulleken, are set to launch an exciting new podcast, What’s Up Docs?, aimed at unraveling the complexities of health, wellness, and scientific advancements. The podcast, airing every Tuesday at 4:30 PM on BBC Radio 4 and BBC Sounds, promises an insightful journey into contemporary health discussions, complemented by exclusive bonus content in ‘Doctors’ Notes’ episodes available on BBC Sounds.

Decoding Health Myths and Scientific Breakthroughs
In an age where information overload can be overwhelming, Drs Chris and Xand van Tulleken take on the challenge of breaking down the latest health trends, scientific discoveries, and wellness debates. With their unique dynamic as identical twins and medical professionals, they explore fundamental questions like:
- How do we determine what’s genuinely good for our health?
- Can we practically apply scientific discoveries to our daily lives?
- How do genetics, lifestyle, and external factors influence well-being?
From testosterone replacement therapy to microplastics in food, from willpower to blood sugar regulation, the podcast covers a diverse range of topics relevant to everyday health concerns.
Expert Guests & Engaging Discussions
Each episode features an expert guest offering valuable insights, research-backed data, and psychological perspectives. Listeners can expect engaging, evidence-based discussions that help navigate the abundance of health advice available today.
Dr. Chris van Tulleken explains:
“We don’t have all the answers, but like many, we’re navigating life’s complexities. How can we be better parents, partners, and professionals while maintaining our health and sanity? Since we’re identical twins, we constantly question—are our struggles genetic, self-inflicted, or shaped by external forces?”
A Battle of Perspectives: The Twins’ Contrasting Approaches to Health
Despite sharing the same DNA, the van Tulleken brothers have differing views on science and well-being. Dr. Xand van Tulleken highlights their perpetual debates:
“Though we’re twins, we see health and science differently, and we never stop arguing! As doctors passionate about public health, we aim to lead better lives while helping others do the same. But how should we invest our time, money, and energy to achieve optimal health? This is where our discussions get really interesting.”
BBC’s Take on What’s Up Docs?
Rhian Roberts, BBC’s Podcast & Formats Commissioner, shares her enthusiasm for the new show:
“Most of us strive for a balanced life—better physical health, mental clarity, and fulfilling relationships. What’s Up Docs? won’t promise miracles, but it will definitely make the journey entertaining and informative. Chris and Xand will be filtering the science and testing what works for them—and hopefully, we all benefit along the way.”
