The Primal Podcast

Dr. David Brownstein, an American physician and author specializing in iodine and thyroid health, explores widespread iodine deficiency and its links to glandular disease, cancer risk, Hashimoto’s, and Graves’ disease. He discusses fluoride and bromide exposure, fibrocystic breast disease, Lugol’s iodine, exact dosing, and why unrefined salt matters for iodine use and detoxification.

Dr. Philip Ovadia, a board-certified cardiac surgeon and author, challenges conventional thinking on heart disease. He explores cholesterol, insulin resistance, processed foods, seed oils, statins, and arterial plaque. The conversation also covers natural animal fats, nutrient-dense diets, ketosis, resistance training, advanced metabolic testing, and whether plaque can be reversed.

Dr. Elizabeth Bright, a physician specializing in thyroid and adrenal health, explores why hypothyroidism and Hashimoto’s are often overlooked. She discusses comprehensive thyroid testing, iodine, goitrogenic foods, gluten, dairy, natural desiccated thyroid, cortisol, fasting, meal timing, animal fats, and stress-conscious exercise.

This episode is brought to you by ⁠⁠The Primal Skincare.Dr Jason Fung is an expert in treating type 2 diabetes and obesity with science. He will explain why it’s not about calories; it’s about insulin and cortisol. Both are important for reducing blood sugar and insulin levels. In this episode, we reveal:The Calorie Myth: Why eating less just slows down your metabolism and leaves you trapped.Fat Storage Mode: How high insulin levels physically lock your fat cells so your body cannot burn them for fuel.Reversing Diabetes: Why type 2 diabetes is a dietary disease that can be reversed, not a life sentence.Food Order Secrets: How changing the order of the foods on your plate alters how your hormones react.Fasting for Freedom: Simple, no-cost fasting methods that reset your body and lower your insulin naturally.

Dr. Joel Brind, research biochemist and author known for glycine work, explains why low glycine causes inflammation, aches and poor sleep. He discusses glycine’s role in shutting off chronic inflammation, promoting deep non-REM sleep, helping blood sugar control, and why modern diets lack enough glycine. Practical sources, dosing, and why supplementation can be helpful are also covered.

Sten Ekberg, holistic doctor, former Olympian and health YouTuber, explains how insulin, stress and metabolism trap belly fat. He discusses why calorie-only advice fails, how meal timing and fewer meals lower insulin, and practical movement and stress tools to unlock stored fat. Short, actionable strategies aimed at lasting change without constant hunger.

Morley Robbins, health researcher and creator of the Root Cause Protocol, advocates mineral-focused metabolic care. He outlines how copper misregulation, magnesium depletion, and iodine interactions drive modern chronic illness. Short, punchy takes cover iron-copper dynamics, why common supplements may harm, practical dietary and topical mineral strategies, and real-world recovery anecdotes.

Dr. Anthony Chaffee, a medical doctor and nutrition researcher focused on diet and the brain. He explains how sugar and carbs harm brain metabolism and aging. He discusses fructose neurotoxicity, why ketones may fuel the brain better, and how animal fats and B12 support repair. He outlines what happens in the first days and weeks after dropping carbs and moving toward a meat-focused approach.

This episode is brought to you by ⁠The Primal Skincare.Is your "healthy" grass-fed beef and pasture-raised chicken actually driving inflammation? In this eye-opening episode, regenerative farmer David Boatright (Fed from the Farm) exposes the massive gap between corporate food labeling and true nutritional quality.From chemical interventions like meat gassing to the regulatory loopholes of "organic" marketing, David breaks down the health consequences of factory farming and provides a practical framework for sourcing nutrient-dense, species-appropriate food that supports long-term metabolic health.In This Episode, We Reveal:The Meat Gassing Illusion: How major corporations use carbon monoxide to mask spoilage and manipulate meat color.The Pasture-Raised Deception: Why the majority of supermarket "pasture-raised" poultry never steps foot outside.The Vegetarian-Fed Chicken Myth: The biological reality of why omnivorous birds require animal protein to yield nutrient-dense eggs.Chemical Interventions in Poultry: What happens to your gut microbiome when you ingest chicken processed in chlorine baths.Hormonal Cascades in Dairy: The medical and endocrine implications of rBST and growth hormones in conventional milk.The Raw Milk Landscape: An objective analysis of the immunological benefits, enzymatic activity, and actual safety profiles of unpasteurized dairy.The Alpha-Gal Epidemic: How the Lone Star tick triggers a life-altering mammalian meat allergy and its connection to immune health.

Prof. Tim Noakes, renowned sports scientist and metabolic health researcher, outlines evolutionary metabolism and why humans may be built to burn fat over carbs. He discusses how carbs drive insulin resistance and obesity. He presents his new 2026 study challenging carb-loading and shows fat-adapted athletes can match performance. Practical guidance on quitting carbs and targeting low fasting insulin rounds out the conversation.
