YOUR GUT IS MAKING YOU ANXIOUS?! šØ

Weāve been taught to think about depression as a chemical imbalanceā¦
But after more than 15 years studying the gut, Tim Spector believes the real starting point might be somewhere else entirely.
My team asked Tim to come back on because the impact of his previous episodes was remarkable.
Tim is a world-renowned scientist and co-founder of ZOE.
I had gut problems for four years and just assumed I was broken. Thatās until I looked into my gut health properly with ZOE. It was so game changing for me that I became an investor in the business.
Timās career has been quite the evolution. He began his career studying twins but over time, that research led him to something much bigger - the microbiome.
Food, inflammation, and how those forces shape almost every part of how we feel.
Timās mum is 93 and has been in a care home for seven years. She has advanced dementia and she no longer recognises him.
That moment forced him to stop and question everything he thought he knew about ageing and the hidden forces that shape our brain. And as he looked deeper, the science kept pointing in the same direction - the gut.
Weāre living longer, but weāre not living better. We have more information than ever, but weāre still tired and confused as to why.
For decades weāve been told that everything starts in the brain - but Tim no longer believes that.
We cover:
- Can dementia be prevented? - How does gut health affect your mood? - Why do processed foods make you overeat? - What are the 8 rules for a healthy brain? - Whatās the best snack for brain health?
One thing I admitted to Tim is that even with everything I know, I still get it wrong.
I still open the fridge late at night and reach for the wrong thing. I still make bad choices when Iām tired or not thinking straight. Itās not because I donāt care. Itās because Iām human.
The answer isnāt just more knowledge. Itās better systems. We need to design our environment in a way that gives us a real chance, because when the system is broken, willpower will never be enough.
Iāve learnt that health isnāt just about information but about the small, invisible choices we make every day when no oneās watching.
I hope this episode gives you the insight or the push you need to make those choices a little easier.
