What the Autoimmune Protocol is, what to eat and avoid, how to plan meals, and how the reintroduction process works — everything in one place.
This guide is for educational purposes only. Always speak with your healthcare provider before making significant dietary changes, especially if you are managing a medical condition.
The Autoimmune Protocol (AIP) is a structured elimination and reintroduction diet designed to reduce chronic inflammation and identify the specific foods that trigger symptoms in people with autoimmune conditions. It builds on the foundations of Paleo eating, with additional specificity for individuals managing conditions such as Hashimoto's thyroiditis, inflammatory bowel disease, rheumatoid arthritis, psoriasis, and lupus.
Unlike a conventional diet, AIP is a time-limited, three-phase protocol — not a permanent way of eating. The goal is not lifelong restriction. It is understanding: using a period of strict elimination followed by systematic reintroduction to build a deeply personalised picture of how your body responds to food.
The protocol works by removing all foods known to disrupt gut integrity, stimulate immune responses, or contribute to systemic inflammation. With those variables removed, the body has the space to begin healing. Symptoms are tracked throughout — so when foods are reintroduced one by one, you can clearly observe what each one does.
By the end of the protocol, you have a personalised food map built around your own biology — not a generic list. That is the outcome AIP is designed to produce.
AIP is most commonly used by people managing autoimmune conditions — particularly those where conventional medicine offers symptom management but limited resolution. It is also used by people with chronic fatigue, persistent digestive symptoms, unexplained joint pain, inflammatory skin conditions, and brain fog who have not found answers through conventional routes.
It is a significant dietary intervention and is not appropriate for everyone. People with a history of eating disorders, those who are pregnant or breastfeeding, and anyone currently underweight should approach AIP with caution and medical guidance.
The elimination phase removes all common immune-triggering foods simultaneously. What remains is a wide, genuinely nourishing range of whole foods — quality animal protein, a huge variety of vegetables, healthy fats, herbs, and select fruit. The AIP plate is not sparse. It's different.
The emphasis during elimination is on nutrient density, not restriction. Organ meats, bone broth, oily fish, colourful vegetables, and good fats are the nutritional foundations of the phase — foods that actively support the gut repair and immune recalibration the protocol is designed to produce.

AIP isn't arbitrary restriction — every excluded category has a documented mechanism by which it can disrupt gut integrity, stimulate immune activity, or contribute to systemic inflammation. Here's what to watch out for, and why each category is excluded.
Hidden ingredients to watch for: Many packaged foods contain non-compliant ingredients under unexpected names — nightshade spices in stock cubes, carrageenan in coconut milk, seed oils in tinned fish, and "natural flavourings" of unclear origin. During elimination, read every label. If you can't verify every ingredient, leave the product on the shelf.
Successful AIP adherence is almost entirely a planning problem. People who struggle on the protocol rarely struggle because of willpower — they struggle because they hit meal times unprepared, surrounded by non-compliant food, with nothing ready to eat. A simple planning system removes that scenario almost entirely.
The most common planning mistake is writing a shopping list without first deciding what you're going to cook. Start with 4–5 meals for the week, then build your list from those recipes. Every ingredient on the list should trace back to a planned meal. This prevents both over-buying and the Sunday evening discovery that you're missing a key ingredient.
AIP cooking from scratch every night is unsustainable for most people. Batch cooking is the solution. A Sunday session — a large braise, a tray of roasted vegetables, a pot of bone broth — means that Monday through Thursday, meals are largely assembly jobs. Add a second shorter session mid-week and you rarely need to cook a full meal under pressure. Leftovers are not a compromise on AIP — they are the strategy.
Breakfast is where most people's AIP day goes wrong because they haven't prepared an alternative to their usual routine. A rotation of three or four go-to breakfasts — leftover protein with greens, coconut yogurt with fruit, a coconut milk smoothie, bone broth with soft vegetables — means mornings are handled without thought. High protein first thing stabilises blood sugar and makes mid-morning compliance significantly easier.
A well-stocked AIP pantry turns any fridge into a ready meal. Coconut milk, coconut aminos, arrowroot, tinned fish, bone broth, and a full range of compliant herbs and spices mean that even a sparse fresh-food day can produce a good meal. The pantry is your insurance policy. Build it once; maintain it as a habit.
Generic recipe websites are not designed for AIP. Filtering for compliance is tedious, and most results won't account for your current phase or what you have in the house. A phase-aware recipe generation tool removes this friction entirely — describe what you feel like eating, and get back a fully compliant recipe built around your pantry. This is what AIP Kitchen's recipe creation tool is designed to do.
Generate your own AIP meal plan with AIP Kitchen. Tell the recipe tool what you feel like eating, and it builds a phase-correct recipe around your pantry — with a full ingredient list, quantities, and method.

Reintroduction is systematic and sequential. You test foods in order of reactivity — from lowest to highest — introducing one food at a time and monitoring your symptoms for 3–7 days before introducing the next. Speed undermines the data. Patience is the method.
AIP Kitchen's reintroduction tracker guides you through all 20 foods across 4 stages. Mark foods tolerated or reacted — and they automatically unlock or stay excluded in your recipe generator.
