The diet is typically implemented in three phases: 1. Elimination Phase: All high-FODMAP foods are removed from the diet for a period of 4-6 weeks. 2. Reintroduction Phase: High-FODMAP foods are gradually reintroduced one at a time to identify specific triggers. 3. Personalization Phase: Based on the findings, a long-term eating plan is developed that minimizes symptom-triggering foods while maintaining nutritional balance.
