The 3 phases of the low-FODMAP diet
Elimination, reintroduction, personalisation — and why phase 1 isn't forever.
4 min read
The low-FODMAP approach was developed by researchers to help people with IBS identify what bothers them. It has three phases — and the goal is to eat as broadly as possible, not to stay restricted.
1. Elimination (2–6 weeks) Swap high-FODMAP foods for low-FODMAP alternatives. Many people notice a big improvement within a couple of weeks. Use Gutprint's food search to check foods quickly.
2. Reintroduction (6–8 weeks) Test one FODMAP group at a time, in increasing portions over three days, while keeping everything else low. Log symptoms carefully — Gutprint's insights will show how each group affects you.
3. Personalisation (ongoing) Bring back everything you tolerate. Keep only your true triggers limited, and know your personal thresholds.
Do it with support
A registered dietitian trained in the low-FODMAP diet can make this process faster and safer, especially if you have a history of disordered eating. Gutprint's doctor report is a great thing to bring to that appointment.
