In this post, we’ll break down:
- What the Low FODMAP diet is
- How it helps people with IBS

What Is the Low FODMAP Diet?
FODMAPs are a group of carbohydrates that are poorly absorbed in the gut. They stand for:
- Fermentable
- Oligosaccharides (like fructans and galacto-oligosaccharides)
- Disaccharides (like lactose)
- Monosaccharides (like excess fructose)
- And
- Polyols (like sorbitol and mannitol)
These fermentable carbs can cause excess gas, bloating, abdominal pain, diarrhea, and constipation in people with IBS. The Low FODMAP diet temporarily removes these foods to give your gut a break — and to help you pinpoint which ones cause the most trouble.
How Can the Low FODMAP Diet Help IBS?
For many people with IBS, this diet brings real relief. In fact, studies show that around 70% of IBS sufferers experience fewer symptoms when following the Low FODMAP diet.
Why it works:
- Reduces fermentation in the gut (less bloating and gas)
- Minimizes food-triggered pain and diarrhea
- Helps calm your gut’s hypersensitive response to certain foods
But it’s not just about cutting foods out — the real power lies in what comes after.
Who Should Try the Low FODMAP Diet?
This diet is not for everyone — and that’s important to know.
It may be right for you if:
- You’ve been diagnosed with IBS by a healthcare provider
- You have consistent bloating, diarrhea, or abdominal pain after eating
- You want to identify specific food triggers, not just avoid everything forever
It’s NOT recommended if:
- You have or are recovering from an eating disorder
- You haven’t ruled out other GI conditions (like celiac disease, IBD, or SIBO)
- You’re using it as a long-term fix — it’s meant as a short-term tool
How Long Should You Follow It?
The Low FODMAP diet has three phases:
- Elimination Phase (2–6 weeks)
You remove all high-FODMAP foods to calm your symptoms and establish a baseline. This phase should be temporary — not something to stay on forever.
- Reintroduction Phase (6–8 weeks)
You slowly reintroduce one FODMAP group or food at a time (like lactose, fructans, etc.) to test your individual tolerance. This is where you’ll learn what your gut can handle.
- Personalization Phase
Once you’ve identified your triggers, you can build a more flexible, long-term eating plan based on what works for you. This makes the diet sustainable — and much less restrictive.
What’s the Reintroduction Phase Like?
Reintroduction is key to the success of the Low FODMAP diet. It helps prevent unnecessary restriction and gives you the freedom to enjoy more foods without fear.
Tips to make it easier:
- Reintroduce one FODMAP group at a time
- Start with small portions and increase slowly
- Keep a food + symptom journal (Free Gut Gossip Food Journal download)
- Space out tests every 3–4 days to monitor changes

Final Thoughts
The Low FODMAP diet isn’t a magic fix — but it is a powerful tool for taking control of IBS symptoms, one food group at a time.
If your gut has been feeling unpredictable, and you’re tired of playing “guess the trigger,” this method could give you clarity — and relief.
And remember: the goal isn’t to avoid foods forever — it’s to understand your gut and support it.
