Fibremaxxing: The Gut Health Trend That Actually Makes Sense
Move over protein obsession.
There’s a new nutrition trend gaining traction — and for once, it’s genuinely evidence-based.
It’s called “fibremaxxing.”
And unlike many social media food trends, this one aligns beautifully with what we know about gut health, microbiome diversity and digestive resilience.
At FIT Nutrition & Testing Clinic, increasing fibre intake is one of the most powerful (and underused) strategies for improving bloating, constipation, blood sugar balance and overall gut function.
But — and this is important — more fibre isn’t always better.
It has to be strategic.
Why Fibre Is Essential for Gut Health
Fibre does far more than ‘keep you regular’.
It feeds your gut microbiome.
When fibre reaches the colon, beneficial bacteria ferment it to produce short-chain fatty acids such as butyrate — compounds that support:
Gut lining integrity
Immune balance
Inflammation regulation
Metabolic health
Hormonal signalling
Low fibre intake is associated with reduced microbial diversity — something commonly seen in IBS, constipation and inflammatory conditions.
Most UK adults consume well below the recommended 30g per day.
Your microbiome notices.
Fibre and Constipation: Why More Isn’t Always Better
If you’re constipated, the default advice is “just eat more fibre.”
But that can backfire if the root cause is:
Gut dysbiosis
Sluggish motility
Dehydration
Food intolerances
Nervous system stress
In those cases, suddenly doubling fibre intake can increase bloating and discomfort.
This is where personalised gut support matters.
How to Increase Fibre Without Worsening Bloating
1. Increase Gradually
Add 3–5g per week rather than dramatically increasing overnight.
2. Focus on Plant Diversity
Aim for 30 different plant foods per week — vegetables, fruits, herbs, spices, legumes, nuts and seeds.
Diversity feeds diversity.
3. Balance Soluble & Insoluble Fibre
Soluble fibre (chia, flax, oats, legumes) supports stool softness and microbiome feeding.
Insoluble fibre (vegetables, wholegrains) supports transit time.
4. Hydrate Properly
Fibre requires fluid to function effectively.
5. Support With Targeted Supplements (When Appropriate)
In some cases, gentle supplementation can support fibremaxxing safely.
For example:
• BioCare BioAcidophilus – a practitioner-grade probiotic to support microbial balance
• Viridian Complete Fibre Complex – a blend of soluble fibres designed to support digestive regularity
These can be helpful when introduced gradually and alongside dietary changes — particularly if constipation or microbial imbalance is present.
As always, supplementation should be personalised.
