Questions, answered

What is the low-FODMAP diet?

FODMAPs are certain carbohydrates that can trigger bloating, gas, and pain in sensitive guts. The low-FODMAP diet — developed by researchers at Monash University — removes them temporarily, then reintroduces them to find your personal triggers. CalmBelly guides you through every step.

Is CalmBelly a replacement for a doctor or dietitian?

No. CalmBelly is an educational and tracking companion to help you follow the low-FODMAP method with confidence. It doesn't diagnose conditions or replace medical advice. If you have ongoing symptoms, please talk to a healthcare professional.

How long does the program take?

The first 'calming down' phase usually lasts around 2–3 weeks. After that you'll reintroduce foods over several more weeks. CalmBelly paces it for you so you always know what to do today — no counting required.

Do I have to count or weigh my food?

No. CalmBelly focuses on simple daily actions and a curated library of safe meals, so you can follow the method without obsessing over numbers.

Is my data private?

Yes. Your logs are yours. CalmBelly is built privacy-first and your personal health information stays with you.
