5 episodes

Chris and Xand are doctors, scientists and identical twins. Well, not quite identical. Xand is 20kg heavier, clinically obese, and has a Covid induced heart condition. 
The reason Xand is overweight is the same reason that most of us in the UK are overweight: Ultra Processed Food or UPF.  
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 destroying our bodies, our brains and the environment. 
Chris wants Xand to quit so he has a plan: to send him on a journey to meet the world’s leading experts on food, weight, taste and addiction whilst encouraging a final UPF binge in a bid to see if he can learn to hate it. 
Simple right? Well it turns out to be way stranger and more emotional than either of them ever imagined...

An episode will drop each Tuesday from July 6, 2021 for 6 weeks.

    UPF is not food

    UPF is not food

    Chris and Xand meet Professor of Chemistry Andrea Sella to try to understand some of the more complex ingredients in Ultra Processed Food aka UPF and the lies they tell us about when we are full and satisfied.
    Dr Fernanda Rauber was on the team who "discovered" UPF, and explains why it exists and that perhaps we are thinking about it in the wrong way. It's not food - it's an industrial formulation of chemicals.

    How did we get so different?

    How did we get so different?

    Chris and Xand have the same genes but the largest weight difference of any twin pair studied in the UK. What happened? 
    They speak to friend and geneticist Dr Giles Yeo to begin to understand the origins of Xand's (and everyone else's) size. How much is destiny, how much might we be able to control?
    (Many thanks to Little Gem TV for the use of a clip from the 2020 documentary, 'Surviving the Virus: My Brother, Covid and Me').

    TRAILER: Series 1: Addicted to Food

    TRAILER: Series 1: Addicted to Food

    Welcome to 'A Thorough Examination with Drs Chris and Xand'. The first series is "Addicted to Food", it's specifically about the 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. Simple right? Well it turns out to be far stranger and more emotional than either of them ever imagined...

Honest and relatable

I am a massive and unapologetic fan of both Chris and Xand. There is an honesty in all of their work and their willingness to bring their whole persons to this podcast resonates on a level that’s makes this truly relatable. There is no push to make a change just an invitation to join them on their journey and make of it what we will.
Thank you to all contributors.

Unnecessary sound effects

Although this program has a lot of useful information which may help people understand why we overeat and end up obese, I cannot get past the frequent scenes where the presenters are eating, making unnecessary, loud, and disgusting noises close to the microphone. If I wanted to subject myself to those sounds I would spend more time in a pigsty listening to the pigs enjoying their fodder.
