Elimination, Core & Modified: Phase 2 of the Autoimmune Protocol

If you’ve ever searched for “AIP Elimination Phase” online, you’ve probably come away more confused than when you started. Conflicting food lists, outdated guidance, and rigid interpretations have made elimination feel overwhelming, restrictive, or even unsafe for some people.

In Episode 53 of the Autoimmune Wellness Podcast, I break down what the Elimination Phase of the Autoimmune Protocol actually looks like today, following the major 2024 update. This post expands on that conversation and gives you a clear, accurate reference for navigating Phase 2 of AIP without fear, guesswork, or unnecessary restriction.

What Is the AIP Elimination Phase?

The Elimination Phase is the most visible part of the Autoimmune Protocol—and for many years, it was mistakenly treated as the entire protocol.

In reality, elimination is just one temporary phase within a much larger framework.

The Elimination Phase is a structured, short-term experiment designed to:

  • Calm immune activation and inflammation

  • Support gut healing and nutrient repletion

  • Create a stable baseline so food reintroductions can be meaningful

This phase is not a forever diet, and it is not about deprivation or perfection. It’s about creating the right conditions to learn how your body responds to food.

.

What the Elimination Phase Is — and Isn’t

One of the most important clarifications about elimination is what it is not.

The Elimination Phase is not:

  • A lifelong way of eating

  • A test of willpower or discipline

  • A rigid rulebook meant to be followed indefinitely

Instead, it’s an evidence-informed tool rooted in immunology, gut health research, and real-world clinical experience. The goal is not to eliminate foods forever—it’s to temporarily remove common immune triggers so they can later be tested systematically during reintroduction.

.

Core AIP vs. Modified AIP: What Changed in 2024?

For the first time in more than a decade, the Autoimmune Protocol was officially updated in 2024. That update introduced two elimination pathways: Core AIP and Modified AIP.

.

Core AIP

Core AIP is the original version of the protocol and the one used in all published medical research. It is the most comprehensive elimination approach and removes:

  • All grains and pseudo-grains

  • All legumes

  • Dairy

  • Eggs

  • Nuts and seeds

  • Nightshades

  • Alcohol, additives, and processed oils

This version is still highly effective and remains appropriate for those who want to follow the research model exactly or who need a more structured reset.

.

Modified AIP

Modified AIP was introduced after years of practitioner feedback, patient outcomes, and clinical experience. It allows select foods that many people with autoimmune disease tolerate well, including:

  • Rice

  • Most legumes (excluding peanuts and soy)

  • Ghee

  • Seeds and seed-based spices

  • Pseudo-grains like quinoa and buckwheat

Modified AIP shares the same goals as Core AIP—reducing inflammation and identifying triggers—but offers a more accessible and sustainable starting point for most people.

Choosing between Core and Modified AIP is not about doing AIP “right.” It’s about choosing the version that best supports consistency, nourishment, and real-life feasibility.

.

What Foods to Focus On During Elimination

While food lists often emphasize what to remove, what makes the Elimination Phase effective is what you add in.

Both Core and Modified AIP emphasize:

  • High-quality animal proteins and seafood

  • Organ meats and collagen-rich foods

  • Colorful vegetables and fruits

  • Healthy fats like olive oil, avocado, and coconut

  • Bone broth and fermented foods

  • Sea vegetables and shellfish for trace minerals

When nutrient density and variety are prioritized, elimination becomes abundant rather than restrictive.

.

How Long Should the Elimination Phase Last?

For most people, the Elimination Phase lasts 30 to 90 days.

This window allows enough time for:

  • Inflammation to calm

  • Gut healing to begin

  • Symptoms to show measurable improvement

Staying in elimination longer than necessary does not lead to better results and can sometimes work against healing by limiting variety and increasing stress around food.

Progress—not perfection—is the signal that it’s time to move forward.

.

Troubleshooting Common Elimination Challenges

The first few weeks of elimination can feel bumpy. Fatigue, cravings, digestive changes, and emotional overwhelm are common—not because AIP isn’t working, but because the body is adjusting.

Common solutions include:

  • Eating enough carbohydrates and calories

  • Increasing meal simplicity

  • Batch cooking and meal planning

  • Supporting sleep, stress management, and hydration

Elimination works best when it’s approached as a supported process, not an isolated dietary change.

.

The Elimination Phase Is Temporary — What Comes Next?

The Elimination Phase is not the destination. It exists to set the stage for the most important part of AIP: reintroduction.

When elimination is done thoughtfully and intentionally, it provides clear information that allows you to build the least restrictive, most nourishing version of AIP that supports your long-term health.

Title: Elimination, Core & Modified: Phase 2 of the Autoimmune Protocol | Deep Dive (Ep 053)

[00:00:00] Introduction: AIP Elimination Phase History and Updates

You’ve set your foundation with the Transition Phase by tracking your baseline symptoms, defining your “why”, and preparing your kitchen. Now comes the part most people think of when they hear AIP: The Elimination Phase. The Elimination Phase is the most visible and most talked about part of The Autoimmune Protocol, and for many years it’s what most people assumed was the entire thing.

But elimination is just one piece of a much bigger picture. If you’ve ever searched for AIP food lists online, you’ve probably seen a dozen different versions, some that don’t match, some that contradict each other, and some that make you wonder, wait, what on earth can I actually eat?

I get it! For a long time, there was confusion about what the Elimination Phase really meant, what to remove, how long to stay in elimination, and how to do it without feeling deprived or overwhelmed.

That’s why in 2024, The Autoimmune Protocol was fully updated and clarified for the first time in over a decade, bringing together all of the medical research, practitioner experience and lessons learned from years of real world use.

Today I’m going to walk you through exactly what the Elimination Phase looks like now, how long it lasts, how to choose between Core AIP and Modified AIP, which foods to avoid, and which foods to focus on to include. By the end of this episode, you’ll have a clear, accurate, and sustainable plan for your Elimination Phase. No guesswork, no overwhelm, and no following the wrong plan.

Welcome back to the Autoimmune Wellness Podcast. I’m your host, Mickey Trescott, and this is the next installment in my AIP Deep Dive series. In the last episode, we talked about the Transition Phase, how to prepare for success with the Elimination Phase. So if you haven’t listened to that one yet, I recommend starting there because a solid transition makes this part so much easier.

Today we’re going to get into the heart of AIP, the Elimination Phase. This is the period when you temporarily remove foods that are known to be potential triggers for inflammation, gut permeability, or immune activation, while emphasizing foods that are most nutrient dense and healing.

Now, I’m going to say this a lot today, it’s not forever. This is a learning process, which entails a short-term investment in understanding what your body truly needs to thrive. And as always, this podcast is not a substitute for medical care, always check in with your healthcare provider before making any changes.

[00:02:38] What the AIP Elimination Phase Is—and Isn’t

So let’s start with what the Elimination Phase is not. First, it’s not a diet to follow forever. Second, it’s not a trend or a rigid set of rules. And third, it’s definitely not about deprivation. The Elimination Phase is an evidence-based tool developed from what we know about how the immune system interacts with food, the gut, and inflammation, and supported by human research and people living with autoimmune disease.

The Elimination Phase is designed as a short term structured experiment that helps calm inflammation, restore balance, and create a clear environment so that you can later identify which foods support your best healing. So, you’re not removing foods to chase perfection, you’re removing potential food triggers so that you can observe your body’s responses and learn from them.

The goal is not to stay in elimination forever, it’s to use this time to intentionally reduce symptoms, rebuild stability, and collect information about your body that will guide your long-term approach. I myself did this 15 years ago, and I’m still using the information that I gleaned from that original process.

So if you’ve ever heard someone say that they have been on AIP for years, that is a misunderstanding. The Autoimmune Protocol is not meant to be lived in elimination. It’s meant to be moved through. AIP is a framework, not a diet, and elimination is just one step in a much larger process of understanding your body and supporting it more effectively over time.

[00:04:18] Updates to The Elimination Phase: Core and Modified AIP

Now let’s revisit one of the biggest updates to The Autoimmune Protocol in more than a decade. There are now two versions of the Elimination Phase, Core AIP and Modified AIP. And if you listen to the last Deep Dive episode, you’ll remember that this update came from many years of work drawing on data from medical research, practitioner feedback, from the AIP Certified Coach community and the real world experience of thousands of people living with autoimmune disease.

The goal of this update was simple, to make AIP more accessible, sustainable, and adaptable without compromising its effectiveness. And so here’s what that means in practice.

Core AIP is the original, comprehensive version of the Elimination Phase. The same one used in all of the published medical studies and the foundation that built the AIP movement as we know it today. It’s still here, unchanged, because we know from both research and clinical experience that it works extremely well.

Now Modified AIP, introduced in 2024, is a newer, more flexible option informed by everything we’ve learned since those very early studies. It was developed in collaboration with practitioners who saw firsthand what was helping their clients and patients succeed, and what sometimes got in the way.

This new version is designed for people who need a less restrictive, more affordable, or more sustainable starting point, while still focusing on the key foods most likely to influence autoimmune symptoms. And if you are still on the fence, this is the version that I recommend most people start with today.

Both versions share the same foundation and the same goal. They help you lower inflammation, identify food triggers, and create a long-term way of eating that supports your body’s unique needs.

In the next part of this episode, I’ll walk you through Core AIP, the complete food lists, what to avoid, what to include, and then highlight exactly how Modified AIP differs.

[00:06:20] Foods to Avoid in the Core AIP Elimination Phase

Alright, so let’s start with the foods to avoid on Core AIP. These are foods that research and clinical experience suggest may contribute to inflammation, immune activation, or changes in gut health in people with autoimmune disease. Now, always remember that this phase is temporary. Every food you remove now will be reintroduced later, one-at-a-time, so that you can see how your body truly responds.

So here’s the complete list of foods to avoid on Core AIP. First, grains and gluten containing foods. All grains are removed during this phase, including barley, corn, millet, oats, rice, rye, sorghum, spelt, teff, and wheat. All varieties, including einkorn and semolina. And this also includes gluten-containing foods like bulgar, farro, rye, and wheat-based products.

Sometimes it’s hard to get down to the nitty gritty, really if it comes from a grain, it’s excluded. Okay. Grains are excluded because their proteins, especially gluten and similar compounds, can stimulate immune activity or irritate the gut lining in people who are sensitive, which is very common for people with autoimmune conditions.

Next, on Core AIP, we remove pseudo-grains and grain-like seeds. This includes amaranth, buckwheat, chia, and quinoa. They are technically seeds but behave like grains in the body and have similar immune effects.

Dairy. All dairy products, milk, cheese, cream, yogurt, kefir, butter, and any foods containing dairy proteins are eliminated. Dairy proteins themselves such as casein and whey can be inflammatory and may impact gut permeability or immune tolerance.

Eggs from any species are also removed. Egg whites, in particular, are common triggers due to their protein structure. Legumes. This includes all beans, lentils, peas, soy, peanuts, and soy-based foods like tofu, tempeh, soy sauce, and edamame. While there are nutritious for some people, legumes have compounds that some people find irritating or that they’re sensitive to.

Nighshades and related ingredients. So this is going to be your tomatoes, potatoes, peppers, both sweet and hot, eggplant, goji berries. These are all members of the nightshade family. We remove them along with any spices made from them, such as paprika, chili powder, cayenne. Nightshades can sometimes contribute to joint pain, inflammation, or digestive upset, in people who have autoimmune conditions.

Processed vegetable oils. Canola, corn, cotton seed, grape seed, peanut, safflower, sunflower, and soybean are removed during the Elimination Phase. Nuts and nut oils.

So all nuts including almonds, cashews, walnuts, pecans, pistachios and others along with nut butters and flours are eliminated. While nutrient-dense, nuts can be allergenic and difficult to digest for some.

Seeds and seed based spices. This includes chia, flax, sesame, sunflower, poppy, mustard, and other seed-derived foods, along with spices made from seeds like cumin, coriander, nutmeg, fennel, and pepper. Seeds can act as immune stimulants in certain people.

Non-nutritive sweeteners and sugar alcohols. Stevia, aspartame, sucralose, saccharin, xylitol, erythritol, and manitol are excluded. Processed food additives and chemicals. So we avoid artificial colors, flavors, preservatives, and gums like carrageenan, guar gum, lecithin, xanthan gum, and hydrolyzed vegetable protein. These ingredients are common irritants and can disrupt gut balance.

And then lastly, alcohol. Beer, wine, liquor, mead, cider, and other alcoholic drinks are also excluded during elimination. Alcohol can increase gut permeability and affect immune function and be problematic for people who are going through this phase.

So I know this is a long list of foods to avoid on Core AIP, but remember. This is not forever, each of these foods will be tested later, one-at-a-time during the

Reintroduction Phase. And while this list focuses on what to remove, what makes AIP work isn’t just the subtraction, it’s what you add back in. Deeply nourishing foods that help your body repair, regulate and thrive.

[00:11:05] Foods to Avoid in the Modified AIP Elimination Phase

Now that you know which foods are eliminated in Core AIP, let’s talk about Modified AIP, the newer, more accessible version of the Elimination Phase. Modified AIP keeps the same foundation as Core AIP, lowering inflammation, supporting the gut, and improving immune balance, but it builds on what we’ve learned from years of research, practitioner feedback, and real world experience.

It’s again, based on those same principles, but designed to make the process more sustainable for people who need a flexible, affordable, and approachable way to begin. Think of Modified AIP as Core AIP plus a few carefully selected additions. Food that both research and clinical experience show are well tolerated by a lot of people in the autoimmune community.

Here is what’s different on Modified AIP. Modified AIP includes rice, all kinds. So rice is excluded on Core AIP, but it is included in Modified. This includes white, brown, wild, and other rice varieties, because they are generally well tolerated and provide an easy to digest source of carbohydrates. So for many people, including rice helps maintain their energy, stabilize blood sugar, and make meals simpler and more satisfying, not to mention affordable.

Next, legumes. So we include legumes, except for peanuts and soy, in Modified AIP, all of them. Peanuts and soy because they are among the most common allergenic and immune reactive foods. Now, other legumes like lentils, chickpeas, black beans, and kidney beans, these are very nutrient dense sources of fiber, iron, and plant-based protein that a lot of people tolerate well, when properly cooked. Now, of course, there are people out there for whom legumes don’t really work for, but if they do work for you, they can be a very affordable and nutrient dense source of your meals.

Next we have ghee, which is clarified butter. And ghee is included on Modified AIP because it contains almost no milk proteins. That’s the part of the dairy that is most likely to trigger immune activity, and it also retains beneficial fats and fat soluble vitamins like A, D, and K2.

Next, we include whole seeds and seed-based spices on Modified AIP. So seeds and their derived spices like cumin, coriander, mustard, sesame, flax, sunflower, and pumpkin are allowed on Modified AIP. They add flavor, texture, and valuable nutrients, and most people tolerate them without an issue.

We also include pseudo-grains. Buckwheat, quinoa, and amaranth are included on

Modified AIP. Now, these technically aren’t grains, they’re actually seeds, but especially when soaked and cooked properly, they provide gentle carbohydrates, fiber and minerals that support gut health and sustainability. Not to mention they are pretty affordable.

So with those exceptions, everything else remains the same as Core AIP during elimination. We remove eggs, dairy, besides ghee, nuts, nightshades, alcohol and additives. So while Core AIP remains the most comprehensive and research tested version of the Elimination Phase, Modified AIP builds on that foundation with a few thoughtful updates that make it easier to sustain an everyday life.

Both versions share the same goal: to calm inflammation, support immune regulation, and help you identify which foods truly support your health. The difference lies in how comprehensive your elimination needs to be and what level of structure helps you stay consistent.

And remember, these additions don’t replace nutrient dense foods of Core AIP, they are included alongside them. So both versions are grounded in whole unprocessed, deeply nourishing foods that form the core of The Autoimmune Protocol.

And if you’d like to see these Core and Modified food lists side by side, which is a lot easier for comparison, I’ve created printable versions to make it simple. Just go to theautoimmuneprotocol.com/foundations or find the link in the show notes.

[00:15:29] Foods to Include in the Core and Modified Elimination Phases

Let’s talk about the part everybody looks forward to, which is the foods you can eat, and the foods that are actually extra nutrient dense that we’re going to want to be adding in a lot of quantity when we’re in the Elimination Phase. So we are really looking for nutrient density and variety. These are the foods that help repair the gut, regulate the immune system, and give your body the raw materials it needs to heal.
Here are the foods that we are looking to include no matter whether you’re on Core AIP or Modified AIP.

First, animal proteins and seafood. So all high-quality meats in seafood are encouraged. This is going to include beef, lamb, pork, poultry, game, fish, shellfish, you name it. Whenever possible, try to get the best quality you can, but also remember that it is not required to do grass-fed, pasture-raised or wild-caught sources in order to successfully experience progress on The Autoimmune Protocol. These proteins provide amino acids and iron and zinc, really high-quality nutrients that support immune balance and tissue repair and they should be a cornerstone of your approach.

Now, this category is one that not everyone is going to opt into and that’s totally fine, but organ meats and offal are some of the most affordable and nutrient-dense ingredients you can use. They include liver, heart, kidney, and tongue, and even a few servings per week can dramatically improve nutrient intake, especially for things like vitamin A, B12, and folate.

I personally am not the biggest fan of the flavor of liver, but I still cook a batch once a month, store it into four portion-size containers in my freezer, and then I eat a portion every one or two weeks, because I notice a major difference in my energy levels and my skin, and in my nutrient status when I don’t have it. I make that a part of my routine even way since AIP.

Next, bone broth and collagen-rich foods. You can make your broth at home, you can buy it at the store, but these are really great sources of gelatin and collagen, which support connective tissue and gut health. They’re rich and amino acids like glycine and proline, and they help maintain that gut lining. They’re also great for your skin and your hair.

Next we have seafood, fish, and shellfish of all kinds are encouraged and especially we like the cold-water, fatty fish like salmon, sardines, and mackerel. Shout out to the little fish, they do a lot of work, they’re very affordable, I like to keep tins of them in my pantry at all times because they are so rich in Omega-3 fats, which have a well-documented anti-inflammatory benefit to us.

Vegetables, and almost all vegetables are included except those nightshades. Aim for a wide range of colors and textures. Really go with what you like, but make sure you are eating a ton of vegetables. Leafy greens, cruciferous vegetables, root vegetables, squashes, onions, leeks, beets and carrots. The greater your variety, the broader your nutrient coverage.

Fruit. Fruit is allowed on The Autoimmune Protocol in all phases. People get confused about this sometimes, and they like to layer sugar-free diets with AIP, but fruit has always been included in The Autoimmune Protocol. Focus on options like berries and apples and citrus. Really anything you like, anything that’s seasonal. Fruit is really high in fiber, in nutrients and antioxidants, and you want to make sure that you’re eating some.

Healthy fats. AIP welcomes nourishing fats such as avocado, olive, coconut, and even animal fats like tallow and lard, duck fat. These fats help with nutrient absorption, hormone production, and satiety.

Fermented foods. Naturally fermented foods that haven’t been pasteurized, so sauerkraut, fermented vegetables, coconut yogurt, kombucha. These all support a healthy gut microbiome and digestion.

Herbs and non-seed spices. So we like to include ample amounts of fresh herbs and non-seed spices like basil, cilantro, parsley, rosemary, thyme, oregano, garlic, turmeric, and ginger. They add tons of flavor and phytonutrients. We want to make sure we’re eating lots of them while in the Elimination Phase and honestly, beyond.

So when you focus on inclusion and variety, the Elimination Phase feels abundant, not restrictive. Every meal becomes an opportunity to nourish your body deeply and learn what truly supports your health. And guess what? These are foods that are healthy for everyone. So learning how to get them into your eating routine is going to help you stay healthy for the long run.

[00:20:17] How Long Should the Elimination Phase Last?

So how long, exactly, should you stay in the Elimination Phase? In most cases, 30 to 90 days is going to be the sweet spot. That window gives your body enough time to calm inflammation, restore balance, and start showing measurable improvement, but it’s also short enough to keep the process sustainable.

The Elimination Phase is not about staying there indefinitely, it’s about gathering information. For most people, somewhere in that one to three month range, the immune system begins to settle down, the gut has a chance to repair and regenerate, and early progress becomes visible.

This process is going to look different for everyone. You might notice your digestion improving, your sleep getting deeper, your energy stabilizing before your pain or your fatigue shift. Some symptoms change quickly, others take more time.

And what matters the most is that you are noticing that change. So if you begin to see steady improvement before you reach that 90 days. That’s great! It usually means that you’re ready to start planning your reintroductions. But if your progress is slower, or if your symptoms fluctuate, it’s okay to stay in elimination a little bit longer.

The key is to stay engaged with the process, not stuck in it. So use the tools that you built during your Transition Phase. Track your symptoms, reflect weekly on your energy and your mood, and look for patterns over time.

That being said, if you’ve been following the Elimination Phase for more than three months, you haven’t seen noticeable change, it’s time to pause and reassess. So long-term elimination isn’t the answer. In fact, staying too long in this phase can limit variety, nutrient intake, and your quality of life. If your progress has plateaued, here are a few ways to troubleshoot before moving forward.

First, review your compliance, so even small exposures can muddy the picture. Revisit your food lists and simplify if needed. Second, assess the nutrient density. Are you eating enough? Are your meals diverse? Are they colorful? Are you undereating or are you eating a lack of variety? Sometimes that can stall progress.

Next, check your lifestyle factors. Now, we haven’t done a episode on this yet, but it is coming soon. But sleep, stress, movement and connection all play a huge role in immune regulation. If one of those is off balance, diet alone might not be getting you the mileage that you’re looking for.

And then lastly, you might need to seek professional support, and at the three month mark , if nothing has changed, this is usually the area that you should go. An AIP Certified Coach or healthcare provider can help you identify things that are underlying, that you’re just not able to work through on your own.

Remember, the Elimination Phase is meant to serve you but not define you. It’s a temporary strategic thing that you are doing to help you learn from your body and move forward with more clarity. Sometimes you need a little bit of help to figure out those details.

So whether your Elimination Phase lasts one month or three, the most important thing is that it feels purposeful, and that you notice measurable changes before moving on to the Reintroduction Phase.

[00:23:32] Troubleshooting Symptoms During the Elimination Phase

Next we’re going to talk about troubleshooting the first few weeks of the Elimination Phase, because this is where most people hit some of their biggest challenges. Even when you’ve planned well, the early days can feel bumpy. You’re changing what and how you eat. Your digestion is adjusting, your energy might fluctuate, and you’re suddenly paying close attention to everything you put on your plate. It’s a lot of change all at once, and that can bring both physical and emotional shifts. Here are some of the most common things people experience early on and what to do about them.

First, if you feel more tired than usual. This is one of the most common early symptoms, as your body adjusts to a different mix of macronutrients, often fewer processed carbs and more whole foods, you might notice temporary fatigue.

Make sure you’re eating enough calories, especially from healthy fats and starchy vegetables like sweet potatoes, plantains or winter squash. Undereating or skipping carbs too drastically can slow recovery and make fatigue worse.

If your digestion changes, bloating, gas, or changes in bowel habits are normal as your microbiome adapts. Remember, your bacteria are shifting to accommodate a new food environment. Focus on variety in your vegetables. Include some fermented foods like sauerkraut or coconut yogurt, and remember to stay hydrated. Bone broth can also be soothing as your digestion stabilizes. And I just want to add a little note that, there are some digestive changes that are in adjustment while you’re in transition to the Elimination Phase. And then there are digestive issues that signal that you might need to seek help from a healthcare provider. So if you are definitely experiencing something new and persistent, don’t hesitate to get checked out.

Next, when cravings hit. So cravings don’t always mean that you lack willpower. They actually can signal that your blood sugar is unstable or that you are adjusting emotionally to a different way of eating. Adding a little more carbohydrates from fruit or root vegetables, making sure you’re not skipping meals, and making sure to find AIP-friendly comfort foods that feel nourishing can be helpful.

And if you miss the emotional comfort of old foods, that’s totally normal. Try replacing the ritual, like a warm drink or a cozy routine after dinner instead of just the food itself.

Next you could be feeling really overwhelmed in the kitchen. Cooking this much can feel like a full-time job at first, and my advice is to simplify wherever possible.

Choose a few go-to meals you can repeat often, rely on batch cooking, and use convenience items like frozen veggies, pre-chopped produce. Remember, this phase is temporary, the skills you build now will make the future eating easier.

Next, if you feel emotionally off or discouraged when your food changes, so do your routines and your biochemistry. Hormones, blood sugar and gut- brain communication are all adjusting. If you feel emotional, it’s not a sign you’re failing. It’s a sign that you are changing. So this is a time to dig in, lean on your support network, stay connected to your “why”, and keep your journal or tracker to see your progress unfold over time.

Now lastly, if your symptoms seem worse before they get better, this can happen in the first few weeks, although there is no such thing as a “detox phase” with AIP.
If you’re feeling measurably worse, that’s a sign that you might need to seek help.

Sometimes though, when inflammation starts to shift, symptoms fluctuate before they stabilize. So as long as things are trending in the right direction after a few weeks, that’s usually a part of the process. But if your symptoms do worsen significantly or new ones appear, pause and seek guidance from your healthcare providers or an AIP Certified Coach. They are trained to help identify whether something needs adjusting.
These first few weeks in the Elimination Phase are a learning curve, but they’re also a time when you build the confidence and systems that carry you through the rest of your time on The Autoimmune Protocol.

So when in doubt, slow down. Focus on consistency rather than perfection. And remember, your body is adapting to a new normal. Change takes time, and you’re doing exactly what you’re meant to creating the space for healing to begin.

[00:27:57] How to Make the Elimination Phase Easy: Meal Planning and Batch Cooking

If there’s one skill that can make or break your success during the Elimination Phase, it’s meal prep. Most people don’t struggle with AIP because they’re unmotivated, they struggle because they’re hungry, tired, and out of time when it’s time to eat.

That’s where meal planning and batch cooking come in. They take the pressure off, remove decision fatigue and make it possible to nourish yourself consistently, even when life feels busy. Here are my best strategies for making this work.

First, start with a plan. Pick three to five meals you know you’ll actually enjoy and repeat them through the week. You don’t need endless variety. You need reliability. Once those meals feel second nature, you can add more diversity.

Two, implement one or two batch-cooking sessions per week. For most people, like myself, Sunday and Wednesday work well, but your schedule may differ, so just pick two days that work for you. Use that time to roast some vegetables, cook a few proteins, and prepare starches like sweet potatoes, rice, or plantains. Two focused hours can save you 10 later. And I’m not just saying that I have actually done the math and cooked in my kitchen to figure it out.

Three, cook once, eat multiple times. Double your recipes so you have leftovers for lunches or for quick dinners. Soups, stews, and sheet pan meals reheat beautifully and make AIP feel effortless.

Four, stock your freezer. Freeze portions of broth, cooked proteins or sauces so that you always have a backup plan on the nights when cooking feels impossible.

Five. Keep a flavor toolkit. Prepping a few sauces or dressings like a coconut ginger sauce and herbed olive oil, or a simple AIP pesto can make the same ingredients feel brand new.

Six, use your tools wisely. So if you have a slow cooker, an Instant Pot, or an air fryer, which none of those are required to do AIP by the way, but they can make certain aspects of batch cooking easier. Let them do the work while you focus on other things.

One of my favorite things to do is start a batch of broth and walk away for the rest of the day, allow my Instant Pot to cook it up, and then just be there to strain it at the end of the day.

Seven, embrace shortcuts. Frozen vegetables, pre-chopped produce, canned fish store-bought AIP sauces. These are not cheating, you guys. They are smart tools that keep you on track.

When you plan and prep this way, AIP stops feeling like a full-time job and starts feeling like a rhythm that you can totally get into. You spend less time worrying about what to eat and more time noticing how much better you feel.

So what does this actually look like in real life? Here’s an example of what a simple week of AIP meals might look like once you’ve done a little prep. At the start of the week, you’ve batched cooked some basics, maybe a tray of roasted vegetables, a pot of soup, some ground beef or shredded chicken, and a starch like rice if you’re on

Modified AIP or roasted sweet potatoes if you’re doing Core AIP.
You’ve also prepped a quick sauce or dressing like an herbed olive oil or a coconut-lime blend to use in your meals all week. Breakfast might look like a bowl of leftover veggies and protein reheated in bone broth, topped with an avocado or a breakfast hash with greens and plantains.

Lunches might be leftovers from dinner. This is what I do all the time. Soups, stews, or proteins served over rice or roasted vegetables, and then your dinners can rotate through a few templates. A sheet pan of salmon, root vegetables, and a drizzle of olive oil. A slow cooker stew with salmon, broth and greens. Ground beef sauteed with cabbage, onions, and a splash of coconut aminos.
If you’re on Modified AIP, you might add a side of lentils or a scoop of quinoa, or a sprinkle of sesame seeds for some variety and texture. And snacks are simple, fruit with coconut butter, leftover protein, or broth with a pinch of salt.

By the end of the week, you’ll have mixed and matched these ingredients into several completely different meals without cooking them from scratch every night. That’s the real magic of meal prep. It gives you the freedom inside a structure that supports healing. You’re not stuck in the kitchen, you’re setting yourself up to succeed.

[00:32:18] Wrap Up and AIP Foundations Series

Let’s recap what we covered today. The Elimination Phase is the heart of The Autoimmune Protocol, but it’s not the whole story. It’s a temporary, structured process designed to calm inflammation, bring your body back into balance, and help you identify your personal food triggers.

Today you learned that there are now two versions of AIP elimination to choose from. Core AIP, the original, comprehensive version used in all the published medical studies, and Modified AIP, the updated, more flexible approach based on what we’ve learned from research and many years of practitioner experience, designed to be more accessible, affordable, and sustainable, while keeping the same foundation of nutrient-dense whole foods.

Whichever version you choose, the goal is the same: to reduce inflammation, understand your body signals, and discover your least restrictive, most nourishing diet for the long term. We also talked about how to make the Elimination Phase work in real life, how to troubleshoot the first few weeks, how to manage cravings or fatigue, and use meal prep and batch cooking to make consistency easier.

Remember, your success doesn’t depend on perfection. It comes from systems, planning and self-compassion. And if you ever feel overwhelmed, come back to the basics. Simple meals built from protein, vegetables, and healthy fats. It really can be that straightforward.

If this episode helped you make sense of the Elimination Phase, be sure to subscribe so you don’t miss the next Deep Dive where we’ll cover the Reintroduction Phase, the step most people skip, and the one that is going to make all of your hard work pay off.
