Why Your Gut Is Inflamed When Your Diet Looks Healthy
You eat salad. You buy whole grain bread. You drink kombucha. So why do your joints ache, your digestion feel unpredictable, and your energy crash by mid-afternoon? The autoimmune paleo diet for gut inflammation is one framework people use to investigate that message, because the place that hurts is not always the place that needs attention.
Autoimmune Paleo Diet for Gut Inflammation: What AIP Actually Is
The autoimmune paleo protocol is a temporary elimination diet designed to calm the immune system and give the gut lining a chance to recover. Angie and Mickey have a blog dedicated to autoimmune paleo. Here’s a link to their get started guide. The goal is not lifelong restriction. It is a structured experiment: remove common triggers, observe what changes, then add foods back one at a time.
How AIP Differs From Standard Paleo
Standard Paleo removes grains, legumes, and dairy. AIP goes further. It also removes eggs, nuts, seeds, nightshades, and seed oils for a season. The reason is that these foods are common triggers for people with an already reactive immune system. AIP is stricter on purpose, and it is meant to be temporary.
AIP Diet for Gut Health: The Elimination Phase Explained
The elimination phase is not a punishment and it is not a cleanse. Autoimmune paleo begins as a temporary therapeutic window rather than a permanent way of eating, and that framing matters because it changes how you behave inside it.
Most practitioners run elimination for 30 to 90 days, but the number matters less than the signal. The real question is not "have I hit day 30?" but "have my symptoms plateaued at a new, lower baseline?" With a yes to the latter question being the most important. But if you don’t find relief after 60 days of consistent effort odds are something else is going on.
I followed autoimmune paleo years ago and there are some foods within that framework that will still be too much for some people. Overall though, it’s a great place to start because it gives you a variety of foods compared to more restrictive approaches.
What the Elimination Phase Is Actually Doing
When the gut lining is compromised, tight junctions between intestinal cells loosen and undigested food particles, bacterial fragments, and endotoxins slip into circulation. The immune response can land anywhere, joints, skin, fascia, the nervous system. Removing common triggers lowers the total antigenic load so the immune system can stop firefighting, and eating fewer refined carbohydrates nudges some people toward fat and ketone metabolism, which many find reduces inflammation and improves insulin sensitivity.
Foods to Remove and What to Eat Instead
Remove: grains (including whole grains), legumes, dairy, eggs, nuts, seeds, nightshades (tomatoes, peppers, eggplant, potatoes, goji), alcohol, added sugar, seed oils, and most processed foods
Eat: grass-fed and pasture-raised meat, wild-caught seafood, organ meats, bone broth, cooked vegetables (especially well-cooked crucifers and squash), small amounts of low-sugar fruit, olive oil, coconut oil, avocado, and animal fats
Emphasize: animal protein at every meal, especially for women over 35
Many women are not eating enough animal protein to sustain muscle mass or overall health, and that problem worsens in perimenopause and menopause when hormone production depends on adequate fat and cholesterol. Body composition and weight loss are not the same thing, and a woman who chases the scale on a restrictive elimination diet can end up frail rather than metabolically healthy.
Why Some Foods on the Remove List Are on the Remove List
AIP is not arbitrary. Each exclusion has a proposed mechanism, and knowing it helps you decide whether it applies to you.
Lectins in grains and legumes resist digestion and can interact with the gut lining; some people react, some do not.
Phytates in seeds, grains, and nuts bind minerals like iron and zinc, which matters more when you are already running low.
Nightshades contain alkaloids such as solanine that some people with autoimmune conditions report reacting to, though the evidence is mixed.
None of these categories is universally bad. The elimination phase is how you find out which ones matter for you.
Running the Phase Without Falling Apart
A few practical rules make the difference between a useful experiment and a miserable month.
Eat enough. Undereating on elimination is the most common mistake. Aim for a palm-sized portion of animal protein at every meal and do not fear fat.
Cook your vegetables. Raw crucifers and salads are harder on a compromised gut than the same vegetables cooked soft.
Keep a daily log. Food, sleep, bowel movements, joint stiffness, headaches, energy. Two weeks of notes will show patterns memory will not.
Symptom tracking beats guessing. Write down what you ate, how you slept, and how your body felt for two weeks before you change anything. Patterns show up fast when you look for them.
When to Move to Reintroduction
You are ready to reintroduce when your symptoms have been stable at a lower baseline for at least two weeks, you are sleeping and eating consistently, and you can describe what "better" looks like in measurable terms. If you cannot tell whether you feel different, you are guessing. Better questions can lead to better understanding, and the elimination phase is where you learn to ask them.
Leaky Gut and Food Sensitivities: Why Your Grandparents Ate Bread
Here is the question that rarely gets asked: why could your grandmother eat bread, tomatoes, and cheese without a second thought, while you feel worse after a sandwich?
Leaky gut, or increased intestinal permeability, is a state where the tight junctions of the gut lining loosen. Undigested food particles and bacterial fragments slip into the bloodstream, and the immune system responds.
Glyphosate, the Shikimate Pathway, and Your Microbiome
Glyphosate, the active ingredient in Roundup, works by blocking the shikimate pathway in plants. Here is the part that matters for us: many gut bacteria also use that pathway to make the amino acids they need. Research shows glyphosate affects more than ½ of gut bacteria.
Since your gut is your second brain this also has huge implications for mental health challenges. From Anxiety to Parkinsons - glyphosate plays a role.
Gut Inflammation and Joint Pain: The Musculoskeletal Connection
A sore knee after a bowl of pasta sounds absurd until you understand the immune system does not respect the boundary between gut and joint. When the gut lining is compromised and the immune system is on alert, inflammation can land anywhere, and joints are a common spot.
Morning stiffness that fades as the day goes on
Aching that moves around without a clear injury
Tenderness in the fascia and trigger points
If that sounds familiar, it is worth investigating rather than assuming it is just age.
AIP Elimination and Reintroduction: A Phase-by-Phase Schedule
Reintroduction is where most people go wrong. Articles tell you to add foods back one at a time and wait a few days, but rarely explain what to write down, how to tell a real reaction from a bad night of sleep, or what to do when the answer is not obvious.
Phase 1: Full Elimination (Weeks 1-2)
Expect an adjustment period. Headaches, fatigue, and irritability in the first week are common and usually reflect carbohydrate reduction, caffeine withdrawal, or a shift in gut bacteria rather than a true food reaction.
Do not judge the diet by how you feel on day four. This phase is about establishing a clean baseline, not about feeling amazing yet.
As a coach I can help you minimize these side effects.
Phase 2: Hold and Observe (Weeks 3-8)
This is the phase most people skip, and it is the most important one. You are not adding anything. You are watching. Track the same handful of markers every day so you have something to compare against later:
Digestion: bloating, gas, bowel frequency and consistency
Musculoskeletal: morning stiffness, joint aches, trigger point tenderness, headache intensity
Energy and mood: afternoon crash, sleep quality, irritability
Rate each on a simple 0-3 scale. The point is to reduce systemic inflammation. This is where cheat days will break your hard work. A gal I coached one said, “Having 4 kids is hard. This is not hard.”
If you’re struggling you likely just need some ideas. Following this diet almost requires looking at food differently. Initially it will feel impossible because right now you’re eating on autopilot. You likely don’t put a lot of thought into what you eat. AIP is simply learning to make a mental shift which will require more effort initially. (Again, where coaching comes in.) But it quickly becomes your new normal and no longer will feel like a big undertaking.
Phase 3: Reintroduction (Weeks 9+)
One food at a time. Three to four days between each new food. One new food per window. That is the whole rule, and it is the rule most people break. Honestly, this is the most challenging part.
A workable order, from least to most likely to provoke a reaction:
Egg yolks, then whole eggs
Seed spices (black pepper, cumin, coriander)
Nuts and seeds, one type at a time (almonds, then walnuts, then cashews)
Dairy, in order of least to most problematic (ghee, then butter, then aged cheese, then yogurt, then milk)
Gluten-free grains (white rice, then oats)
Legumes (green beans, then chickpeas, then lentils)
Nightshades, one at a time (peeled potatoes, then tomatoes, then peppers)
Gluten-containing grains last, if at all
Troubleshooting Reintroduction When Symptoms Return
If symptoms flare after a reintroduction, stop that food and return to baseline for a few days, then try a smaller amount or a different preparation.
Ambiguous results are the hardest part. A food that produces a clear, repeatable reaction is easy to retire; a mild headache on a night you slept four hours is not.
Reintroduction is not a test of willpower. It is a test of attention. The information you collect here is what makes the whole protocol worth doing.
Phase 4: Maintenance
Keep what works and retire what does not. Some people end up with a broad, varied diet and a handful of permanent exclusions; others feel best on a Paleo or Primal template long term, and a few find a ketogenic or carnivore-leaning approach suits them better. There is no single right answer, and the fact that the answer is individual is the point.
What the Research Actually Shows
It is worth being honest about the evidence. AIP has been studied in small trials and case series, most notably in inflammatory bowel disease and Hashimoto's thyroiditis, with reported improvements in symptoms and some markers of inflammation.
When to Get Help Instead of Going It Alone
Persistent digestive symptoms deserve a real evaluation. Unintentional weight loss, blood in the stool, anemia, fevers, or symptoms that wake you at night are reasons to see a clinician before you change your diet, not after.
That is where coaching can help. If you are trying to sort out what your gut is telling you and want someone to help you ask better questions, track patterns, and interpret what you find, health coaching with Jennifer is a logical next step.
Conclusion: Better Questions About Your Body
Your body is giving you information, and the autoimmune paleo framework is one way to start reading it. If you are tired of being told your aches are just part of getting older, let's get curious together. Health coaching with Jennifer can help you ask better questions, spot patterns, and investigate what actually fits your body.
Frequently Asked Questions
Can the autoimmune protocol diet reduce gut inflammation?
Some small studies and clinical reports suggest the autoimmune paleo approach may reduce markers of gut inflammation and improve digestive symptoms in certain people, but the evidence is still limited and mixed. Dr. Sarah Ballantyne, who developed much of the AIP framework, emphasizes that it is an elimination diet designed to help individuals identify their own triggers, not a guaranteed treatment. If you have an autoimmune diagnosis, talk with your healthcare professional before making major dietary changes.
How long should someone follow the AIP elimination phase before reintroducing foods?
Most AIP guidance suggests staying in the elimination phase for at least 30 to 60 days, and some people need longer before symptoms settle. The key decision point is whether your gut symptoms, joint aches, skin issues, or fatigue have clearly improved. If nothing has changed after a couple of months, the diet may not be the right lever for you, and that is useful information too. Reintroduce one food at a time, every four to seven days, so you can tell what your body is responding to.
Why might someone become sensitive to foods they used to tolerate?
Food sensitivities are not fixed. The gut lining, the microbiome, stress, sleep, medications, and environmental exposures all influence how your immune system responds to what you eat. Glyphosate-based herbicides, for example, interfere with the shikimate pathway used by gut bacteria, which may shift the microbiome in ways that affect immune regulation. So a food that sat fine ten years ago can become a problem when the terrain around it has changed.
Can impaired gut health be associated with muscle and joint aches?
Yes, this connection is worth investigating. When the gut lining is compromised, bacterial fragments and undigested food particles can enter the bloodstream and provoke immune activity that shows up as joint stiffness, muscle aches, or tendon pain. Many people notice their aches ease alongside digestive improvements on AIP. Bodywork can address the muscular and fascial patterns that have built up during that time, while dietary changes work on the other side of the equation.
If you have been chasing answers for years without a clear picture, you are not out of options. I combine medical massage and health coaching to help you look at the whole person, not just the spot that hurts. My goal is lasting relief through understanding, not a quick fix.
The Other 23 — Spiral Notebook
Your massage might last an hour. Your life happens during the other 23.
This notebook is a place to pay attention to those hours.
Because feeling better isn't only about what happens on the massage table—or in the gym, or on the scale. It's the little things you do, think, eat, drink, and experience throughout the rest of your day that add up to the bigger picture.
Use The Other 23 to keep track of the things that matter to you:
🥩 What you ate and how you felt afterward
😴 Sleep, energy, and recovery
☀️ Time outside and exposure to sunlight
🚶 Daily movement and activity
🧠 Mindset, stress, and things worth noticing
💧 Hydration and habits
✨ Wins, observations, experiments, and “aha!” moments
Or don't track a damn thing. 😉
It's also simply a really nice notebook.
Use it for your grocery list, work notes, sketches, brilliant ideas, hiking plans, journaling, brain dumps, or the random thought that arrives while you're standing in the shower and absolutely must be written down before it disappears.
The point isn't perfection. The point is paying attention.
Your body is giving you information all day long. Sometimes you just need a place to write it down.
Inside you'll find:
• 118 ruled pages (59 sheets) of smooth 90 gsm paper
• A sturdy 350 gsm front and back cover
• Metal spiral binding that lies flat for comfortable writing
• A handy document pocket inside the back cover for receipts, notes, tickets, or loose ideas
• Compact 6" × 8" size—easy to carry in a bag, backpack, or tote
• Dark grey back cover for a clean, grounded finish
Take it to work. Throw it in your hiking bag. Keep it beside your bed. Bring it to your next massage.
Use it to track your habits. Use it to clear your head. Use it to figure out what makes you feel good.
Or just use it to write stuff down.
Because what happens during The Other 23 matters.
