Gut Healing on AIP: What’s Really Happening | Deep Dive (Ep 090)

Episode 90: Gut Healing on AIP — What’s Really Happening | Deep DiveWhen most people start the Autoimmune Protocol, they naturally focus on the food: what to remove, what to eat instead, and how to navigate all of the planning that comes with a major dietary change.But one of the most important things happening during AIP is often something you can’t actually see—changes happening inside the gut itself.Because AIP isn’t just designed to remove potential food triggers. It’s also designed to support systems commonly affected in autoimmune disease, including the gut lining, the microbiome, nutrient status, and immune regulation.And those changes don’t always happen quickly or in a straight line.For many people, healing happens gradually over time. Digestion may become more stable. Energy may improve. Foods that caused symptoms early on may become tolerable much later in the process.In this episode of the AIP Deep Dive series, Mickey explains what’s actually happening in the gut during AIP and why healing often continues long after the elimination phase ends.She explores intestinal permeability, the microbiome, nutrient density, lifestyle factors, and why healing is often more about rebuilding resilience than achieving perfection.In this episode, you’ll learn:Why the gut plays such an important role in autoimmune diseaseWhat intestinal permeability (“leaky gut”) actually meansHow stress, sleep, and lifestyle affect gut healingWhat changes may happen in the microbiome during AIPWhy nutrient density is essential for repair and immune regulationHow reintroductions provide information about healing capacityWhy healing and food tolerance can evolve over timeHow to approach setbacks and reactions with more patience and clarityResources:The New Autoimmune Protocol (Book) – A practical guide to implementing AIP with a focus on preparation, sustainability, and personalizationThe Nutrient Dense Kitchen – A cookbook and resource focused on nutrient density for healingAIP Foundation Series – Free 5-day email course with food lists, meal plans, and beginner toolsEpisode 51: The AIP in 2026Episode Timeline:00:00 – Introduction and Mickey’s personal gut healing story04:35 – Why the gut matters in autoimmune disease09:10 – Intestinal permeability (“leaky gut”) explained14:10 – How the microbiome shifts during AIP17:55 – Why nutrient density supports repair21:30 – The role of lifestyle, stress, and sleep25:31 – Why healing isn’t linear31:22 – Wrap-up and key takeaways
