What happens when you don’t eat enough fibre?

Send us Fan Mail Check out the new website: In this episode we take a deeper look at fibre — and why it’s doing far more in the body than most people realise. For years, fibre has been framed as something that simply “keeps you regular”. But the reality is far more interesting. Fibre plays a central role in gut health, cholesterol regulation, blood sugar control, appetite signalling, and even inflammation. In this episode, I walk you through what actually happens inside the body when fibre intake is consistently low. We explore how fibre feeds the gut microbiome, how this leads to the production of short-chain fatty acids like butyrate, and why these compounds are so important for maintaining the integrity of the gut lining and regulating inflammation. We also look at how fibre influences cholesterol metabolism through bile acid recycling, how it stabilises blood sugar responses, and why it plays such a key role in appetite control and long-term metabolic health. This is a practical, science-based breakdown designed to help you understand why fibre is not just an optional extra — but a foundational part of a healthy diet. If you’ve ever wondered whether you’re getting enough fibre, or why it matters beyond digestion, this episode will give you a much clearer picture.
