Why “eat more fibre” isn’t always the answer
If you’ve tried increasing fibre because you want better gut health, clearer skin or improved digestion, but instead experienced bloating, discomfort or unpredictable bowels, you’re not alone.
Many patients come to the clinic feeling confused because they’ve followed well-intentioned advice to “eat more fibre”, yet their symptoms haven’t improved and might have even worsened.
The truth is: fibre is powerful medicine for the gut, but only when the right type, amount and timing are used for your individual physiology.
Here are the most common fibre mistakes I see in clinical practice, and what to do instead.

Quick Summary: Why Fibre May Not Be Working for You
Eating more fibre doesn’t always improve gut health. In some cases, it can worsen bloating, IBS symptoms or digestive discomfort. Fibre needs to be matched to your individual gut function, microbiome and lifestyle.
The 7 most common fibre mistakes I see in clinic are:
✔ Increasing fibre too quickly
✔ Choosing the wrong type of fibre for your gut
✔ Adding fibre without supporting gut motility
✔ Eating high fibre meals without enough protein or healthy fats
✔ Overlooking FODMAP sensitivities
✔ Using fibre supplements before building foundations
✔ Ignoring underlying gut imbalances
If fibre seems to make symptoms worse rather than better, a personalised approach is often the missing piece.
1. Increasing Fibre Too Quickly
One of the biggest causes of bloating is not fibre itself, but how fast it’s introduced.
Your gut bacteria adapt to fibre over time. A sudden jump from a low-fibre diet to smoothies boosted with fibre supplements, large legume-based meals and high-fibre cereals can overwhelm the microbiome, leading to:
- gas and bloating
- abdominal discomfort
- loose stools or constipation
- reflux or pressure
What works better:
👉🏻 Gradual increases over several weeks allow beneficial bacteria to adjust and produce fewer irritating gases
👉🏻Choosing a wide variety of high fibre foods to feed different beneficial microbes and support a balanced microbiome. Not all gut bugs eat the same food!

2. Choosing the Wrong Type of Fibre for Your Gut
Not all fibre behaves the same way.
Some fibres are highly fermentable and feed gut bacteria quickly. Others help regulate stool consistency or support bowel motility. This is because different fibre types are digested in specific parts of the colon.
For example:
- highly fermentable fibres may aggravate sensitive IBS guts
- certain fibres can worsen diarrhoea
- others may be ineffective for constipation
This is why two people eating the same “healthy” diet can have completely different digestive responses.
Clinical insight:
In clinic, fibre is often prescribed strategically depending on symptoms, microbiome patterns and tolerance.

3. Adding Fibre Without Supporting Gut Motility
Fibre relies on movement through the digestive tract.
If gut motility is slow, simply adding more fibre can feel like adding traffic to an already congested road.
Common contributors include:
- chronic stress
- inadequate hydration
- low physical movement
- thyroid or hormonal influences
- disrupted nervous system signalling
- medications that change gastrointestinal motility
What works better:
Supporting nervous system regulation, hydration and meal rhythm alongside fibre changes.
4. Fibre Without Enough Protein or Healthy Fats
Many people unintentionally replace balanced meals with large salads, smoothies or high-fibre snacks.
While fibre is essential, meals that lack protein and fats may lead to:
- poor satiety
- unstable blood sugar
- ongoing cravings
- sluggish digestion
Balanced meals help coordinate digestive signals and improve fibre and overall food tolerance.
5. Overlooking FODMAP Sensitivities
Some high-fibre foods are also high in fermentable carbohydrates (FODMAPs). FODMAPs fibres are rapidly fermented in the first part of the colon and for individuals with IBS, SIBO or post post-infection gut sensitivity, high FODMAP foods like onions, legumes, apples or certain grains may trigger symptoms despite being nutritionally beneficial.
This often leads people to believe fibre itself is the problem.
In reality:
The issue is usually specific fermentable fibres, not fibre overall. Temporary restriction of FODMAPs foods can ease symptoms while the underlying drivers of the sensitivity are supported and then the FODMAPs foods can be reintroduced in a structured way.
6. Trying Supplements Before Building Foundations
Fibre supplements can be helpful tools but they are not interchangeable with whole foods.
Jumping between products or choosing supplements based on online trends may worsen symptoms.
Different fibres influence:
- stool form
- microbial balance
- inflammation
- gas production
Without understanding the underlying gut pattern, supplementation becomes trial and error.
7. Ignoring Underlying Gut Imbalances
Sometimes fibre intolerance is a clue rather than the problem itself.
Persistent reactions to fibre may indicate:
- microbial imbalance (dysbiosis)
- post-antibiotic gut disruption
- intestinal inflammation
- impaired digestive function
- chronic stress affecting gut signalling
When these factors are present, the gut may need support before fibre intake can be optimised.
🚩 New or persistent intolerance to regular amounts of dietary fibre may indicate underlying digestive conditions like inflammatory bowel disease, diverticulitis or strictures and should be investigated by your doctor.
The Takeaway: Fibre Should Help You Feel Better
When fibre is matched correctly to your body, people commonly notice:
- more regular bowel movements
- reduced bloating
- improved appetite regulation and reduced cravings
- improved energy
- better skin health
- greater resilience to stress and illness
If fibre consistently makes you feel worse, it doesn’t mean you need less fibre. It usually means your gut needs a more personalised approach.
How We Approach Fibre in the Clinic
At Your Remedy Naturopathy, fibre recommendations are never generic.
Assessment considers:
- digestive symptoms and bowel patterns
- skin or hormonal concerns
- diet history and tolerance patterns
- lifestyle and nervous system factors
- when appropriate, functional gut testing
- If, needed, referral to your medical practitioner
Small, targeted adjustments often produce far better results than simply “eating more fibre.”
If you feel stuck despite doing the right things for your health, personalised guidance can help identify what your gut actually needs.

Frequently asked fibre questions
Can fibre make bloating worse?
Yes. Rapid increases in fibre or choosing highly fermentable fibres can increase gas production, especially in sensitive or IBS-prone guts.
Should I stop eating fibre if it causes symptoms?
Usually no. Symptoms often indicate the type or amount of fibre needs adjusting rather than eliminating fibre altogether.
What is the best fibre for IBS?
The best fibre varies depending on whether constipation, diarrhoea or mixed symptoms are present. Personalisation is important.
Are fibre supplements necessary?
Not always. Many people benefit from food-first strategies, while others respond well to targeted fibre supplementation guided by symptoms.
How long does it take the gut to adjust to fibre?
Most people adapt within 2–4 weeks when fibre is increased gradually and supported by hydration and balanced meals.
How much does a consultation cost?
Consultation fees are transparent and available before booking. Fees are for consults only. Any products purchased from the dispensary are an additional cost.
The current consultation fees can be found on the Book a consult page. Naturopathy is not covered by Medicare. Some private health insurance funds offer rebates for Naturopathy. Check with your fund for details.
