What if some of the foods we consider “healthy” are contributing to gut dysfunction in certain people? In this episode of The Health Pulse, we take a deep dive into the Paleolithic Ketogenic Diet (PKD)—a highly restrictive therapeutic approach centered on red meat, animal fat, and organ meats while excluding dairy, grains, legumes, and nearly all plant foods. We explore the theory driving PKD: that intestinal permeability, or "leaky gut," may play a central role in autoimmune disease, chronic inflammation, and metabolic dysfunction. We break down the science behind tight junctions, zonulin, and the gut barrier, explaining how a compromised intestinal lining may allow unwanted substances to trigger immune activation throughout the body. We also tackle the most controversial aspects of PKD, including the dairy paradox—why even butter and cream are excluded—and the ongoing debate surrounding fiber, gut health, and the role of beta-hydroxybutyrate (BHB) during deep nutritional ketosis. Along the way, we examine an alternative explanation for some of the reported benefits: PKD may function as one of the most powerful elimination diets ever created, removing ultra-processed foods, seed oils, refined carbohydrates, and common dietary triggers all at once. Finally, we discuss the clinical claims often associated with PKD, particularly in conditions such as Crohn's disease, autoimmune disorders, and metabolic disease, while emphasizing the difference between intriguing case reports and high-quality clinical evidence. We also cover the laboratory markers that should be monitored by anyone considering a therapeutic dietary intervention, including fasting insulin, fasting glucose, HbA1c, hs-CRP, vitamin D, B12, folate, and iron studies. Whether you're interested in gut health, autoimmune disease, ketogenic therapies, or the evolving science of nutrition, this episode offers a balanced and evidence-based look at one of the most debated dietary approaches in modern medicine. 📞 Need lab work done from the comfort of home?
