What is an elimination diet?

An elimination diet is a protocol that helps identify foods causing symptoms. You temporarily eliminate suspect foods for 2-4 weeks, then reintroduce them one by one while observing reactions. It's the most reliable diagnostic tool for food intolerances.

Phase 1: Elimination (2-4 weeks)

Eliminate common allergens and irritants: gluten, dairy, eggs, soy, corn, peanuts, tree nuts, fish, shellfish, refined sugar, alcohol, caffeine. Eat simple, unprocessed foods. Keep a detailed symptom journal.

Phase 2: Reintroduction (4-8 weeks)

Reintroduce one food at a time, for 2-3 days, with 3-4 days pause between each. Note every symptom: digestive, skin, energy, cognitive. If a reaction occurs, eliminate that food and wait for symptoms to clear before continuing.

Phase 3: Personalization

Once triggers are identified, build your personalized diet by avoiding problematic foods. Some intolerances depend on quantity: you may be able to tolerate small occasional portions.

Important

Never go below 1200 kcal/day (women) or 1500 kcal/day (men) without medical supervision. Too aggressive a deficit can be dangerous for your health and counterproductive for weight loss.

Elimination Diet Guide

Important: Consult a healthcare professional before starting, especially if you have pre-existing health conditions, are pregnant, or have a history of eating disorders.

The elimination diet is the most accurate tool for identifying what doesn’t work for you. It requires rigor, but the results are worth it.
