For years, the fitness industry has been obsessed with protein. Protein yoghurts. Protein bars. Protein everything. No one is denying that protein is essential for recovery, strength and performance. But that focus has come at a cost – we’ve stopped paying attention to fibre. 

According to an article in the Guardian, the average adult in the UK consumes around 16g per day, when the recommendation is closer to 30g+. Let’s face it, that’s not a small gap!

From “Protein First” to “Fibre First” 

It’s not just hype. Fibre plays a role in: 

  • Gut health  
  • Blood sugar control  
  • Cholesterol reduction  
  • Satiety (feeling full)  
  • Reduced risk of chronic disease  

In simple terms: protein helps you build the body, fibre helps you regulate it. 

The GLP-1 Effect (Why Fibre Is Suddenly “Trendy”) 

Here’s where it gets really interesting—and very relevant to what clients are hearing. 

With the rise of weight-loss drugs like Ozempic (GLP-1 agonists), people are becoming more aware of: 

  • Appetite regulation  
  • Blood sugar control  
  • Feeling full for longer  

Fibre has been quietly doing a version of this all along. Research shows that fibre can: 

  • Slow gastric emptying  
  • Increase satiety  
  • Stimulate gut hormones

It’s the kind of foundational nutrition that’s been overlooked while trends have taken centre stage. 

Simple Takeaways 

  • Aim for 25–30g+ fibre per day  
  • Include more whole plant foods (veg, fruit, grains, legumes)  
  • Increase intake gradually  
  • Stay well hydrated  

Final Thought 

Protein isn’t the problem, the imbalance is. Fibre isn’t replacing protein—it’s restoring what’s been missing. And for many clients, that shift could be the simplest way to improve their health, performance and results.
