Structured low FODMAP with safe reintroduction
Low FODMAP is a diagnostic tool, not a lifestyle. We do it properly — from investigation to reintroduction.
In short
What is the low FODMAP diet?
Low FODMAP is a three-phase approach developed by Monash University to identify which fermentable carbohydrates trigger IBS symptoms.
Phase 1 is strict and short, phase 2 is reintroduction, phase 3 is your personal long-term diet.
It's not meant to be a lifelong, restrictive diet — the goal is the widest possible range of food with the fewest possible symptoms.
Does this sound familiar?
This might sound like your situation
Most people notice a clear improvement in bloating, gas and pain within 2–6 weeks on structured low FODMAP.
- You've heard of low FODMAP but don't know where to begin
- You've started on your own and are stuck in the elimination phase
- Your diet has become narrow and you miss variety
- You're unsure how to reintroduce food safely
- You want a time-limited plan, not a lifelong diet

What makes the biggest difference?
For low FODMAP, success depends on discipline in phase one and honesty in phase two.
Strict elimination phase
Even small amounts of high-FODMAP food can blur the results in the first weeks.
Structured reintroduction
Testing one FODMAP group at a time is what reveals your real triggers.
Guidance from a specialist
Professional support prevents the diet from becoming unnecessarily long or restrictive.
Nutrient adequacy
Fibre, calcium and variety need attention while intake is reduced.
A clear end point
Planning the return to a broader diet from day one keeps the process time-limited.
When is it not suitable?
Low FODMAP isn't for everyone — and isn't the first choice without a diagnosis.
- Unresolved alarm symptoms
- An eating disorder or strongly restrictive diet
- During pregnancy without professional guidance
- In children without a specialist involved
- Suspected coeliac disease that hasn't been ruled out
We always recommend investigation before starting — and professional guidance along the way.
Common questions
What people ask us most often.
How long does it take?
Typically 2–4 weeks of elimination, then 6–10 weeks of structured reintroduction.
Is low FODMAP safe long-term?
Strict low FODMAP over a long period isn't recommended. The goal is to find your own limits.
Personal nutrition
No one with structured low FODMAP with safe reintroduction is exactly the same
Age, everyday life, activity level, other conditions and what you actually enjoy eating determine what works for you.
That's why two people in the same situation need different advice. SmartEating AI learns your situation over time and tailors suggestions to your body, goals and everyday life.

The knowledge behind the advice
Fibre
Fibre comes from plants and plays a key role in digestion, blood sugar regulation and a healthy gut microbiome. Most people in Norway eat less fibre than recommended, and it is often one of the easiest places to start when improving your diet.
Vegetables
Vegetables are one of the most recommended food groups in any diet, known for their low energy content and high content of vitamins, minerals, fibre and plant compounds. A varied and generous intake of vegetables is one of the clearest recommendations in nutrition.
Oats
Oats are a wholegrain product that have long been a staple of Norwegian cooking, and are receiving increasing attention for their favourable nutritional profile. They are an affordable, versatile and filling source of fibre, carbohydrates, and several vitamins and minerals.
