Quick answer: The elimination diet follows a simple schedule. Remove potential trigger foods for six weeks, reading labels carefully. Then reintroduce one food at a time in small amounts, increasing if there are no symptoms, and record everything in a food diary. Finally, in the maintenance phase, build a long-term diet that avoids only your confirmed triggers.
Phase 1: Elimination (6 weeks)
Remove potential trigger foods to give your gut a rest and calm inflammation. Read labels to avoid hidden ingredients. Lists: foods to avoid and foods to include.
Phase 2: Reintroduction
Reintroduce one food at a time. Start with a small amount in the morning; if there are no symptoms, eat two larger portions later that day, then wait before the next food. Use a food diary throughout. Details: phased reintroduction.
Phase 3: Maintenance
Modify your diet based on your triggers, keeping it as varied and nutrient-dense as possible. See after the elimination diet.
Before you start
- Talk with your provider if you have a medical condition, are pregnant or have a history of disordered eating
- Get tested for celiac disease before removing gluten if you suspect it
- If you have a known or suspected food allergy (hives, swelling, trouble breathing), do not reintroduce that food at home. Work with an allergist.
