If you often struggle with digestive discomfort, skin problems, migraines, or unexplained fatigue, an elimination diet may help identify hidden food sensitivities or intolerances. Unlike trendy fad diets, the elimination diet is a short-term plan designed to remove potential trigger foods and then reintroduce them strategically to see which ones cause symptoms.
This blog will cover everything you need to know about the elimination diet — how it works, what foods to avoid, benefits, risks, and helpful tips for success.
What Is an Elimination Diet?
An elimination diet is a temporary eating plan that removes certain foods or food groups suspected of causing adverse reactions. After a few weeks, foods are slowly reintroduced one at a time to identify any triggers.
Healthcare providers often recommend elimination diets to manage conditions like:
-
Food intolerances (e.g., lactose, gluten)
-
Irritable Bowel Syndrome (IBS)
-
Migraines or chronic headaches
-
Skin conditions like eczema
-
Autoimmune flare-ups
How Does the Elimination Diet Work?
-
Elimination Phase (2–6 weeks):
-
Remove common trigger foods such as dairy, gluten, soy, eggs, nuts, shellfish, caffeine, alcohol, and processed foods.
-
Focus on whole foods like lean proteins, fruits, vegetables, and gluten-free grains.
-
-
Reintroduction Phase (1–2 weeks per food):
-
Slowly reintroduce one eliminated food at a time.

Observe for symptoms such as bloating, rashes, fatigue, or headaches.
