[If you enjoy this podcast, please give us a rating and review on Apple Podcasts, so more people will find The Rational Wellness Podcast. Also check out the video version on my WeitzChiro YouTube page.] Podcast Highlights Rethinking Probiotics: Keystone Anaerobes, Butyrate, and Microbiome Ecosystems with Designs for Health Dr. Ben Weitz introduces the Rational Wellness Podcast episode challenging the assumption that gut issues are solved by adding more traditional probiotics, arguing microbiome repair is an ecosystem and function problem. He interviews Dr. Oscar Cozo and Danielle Arnold of Designs for Health about differences between transient aerobic probiotics (e.g., lactobacillus/bifidobacteria) and keystone anaerobic strains that form the microbiome's foundation, can engraft, drive down gut oxygen, and support cross-feeding. They discuss live, refrigerated delivery for anaerobes; a spore-capable keystone strain (Anaerostipes); and a case study showing improved food allergies, normalization of Akkermansia, increased butyrate-related effects, and reduction of opportunists without antimicrobials. They cover butyrate's roles (tight junctions, mucus, immune regulation, HDAC inhibition), fiber and resistant starch strategies, stool testing (GI-MAP additions for anaerobes and short-chain fatty acids), diet restriction concerns, and practitioner support and case report publishing with Designs for Health. 00:00 Show Intro and Mission 01:00 Probiotics vs Ecosystem Thinking 02:56 Aerobes vs Anaerobes Explained 07:06 Keystone Species and Engraftment 09:18 New Anaerobic Strains and Allergy Research 11:06 Live Shipping and Feeding the Strains 14:03 Case Study Crowding Out Dysbiosis 18:03 Rethinking the Five R Protocol 24:26 Testing and Prebiotic Pairings 26:52 Butyrate and Microbiome Benefits 28:40 Conventional Probiotics Still Matter 35:04 Sponsor Break Apollo Wearable 36:37 Crowding Out Pathogens and Fungi Role 39:58 Archaea and Mucosa 41:21 Mucus Layer and Biofilms 43:11 Feeding Keystone Microbes 44:18 Fiber Targets and Tolerance 46:51 Probiotic as SIBO Option 48:54 Resistant Starch Basics 51:52 Stool Test Dysbiosis Patterns 54:32 Akkermansia and Metabolism 56:44 Histamine Bugs and Enzymes 01:02:26 Gut Healing Nutrients 01:05:34 Diet Diversity and Reintros 01:08:21 Wrap Up and Product Details 01:13:10 Podcast Outro and Clinic Info Dr. Oscar Coatzee has over 25 years experience in psychology and nutrition and is currently the VP of clinical education and practitioner support at Designs For Health.

  • The Hidden Causes of Autoimmune Disease (Dr. Arland Hill) — How to Reverse It: RWP6
    Feb 24 2026

    The Hidden Causes of Autoimmune Disease (Dr. Arland Hill) — How to Reverse It: RWP6. Dr. Arland Hill is a Functional Medicine Clinician and Author of "Platform Food, Function, Freedom.com." Dr. Hill has an in depth conversation with Dr. Ben Weitz about Autoimmune Diseases.

    Dr. Arland Hill explains the primary reasons why there has been an increase in the rate of autoimmune diseases in the United States. The mass food production has significantly altered what is now classified as food as compared to that prior to the 1940's. The combination of drastic changes in our diet and increased toxin exposure in a post-industrialized society has contributed to the rise in autoimmune disease.

    An important variant is the effect of stress. Stress breaks down the body's systems, which can create dysregulation in the immune system. This opens the door for leaky gut syndrome and can manifest in autoimmune issues. Environmental and food toxins coupled with increased stress levels can be the perfect breeding ground for autoimmune diseases to develop. However it is important to note that each of these individual factors can cause autoimmune disease to manifest on their own.

    Western medical doctors treat diseases by providing medications that suppress the immune system such as corticosteroids, chemotherapy agents and newer injectables. TNF alpha blocking agents like Humira and Remicade block the immune system, which is needed to maintain homeostasis, fight off and prevent the disease processes from beginning. These drugs have very serious side effects that include depressing the immune system and worsening the effects of infections and cancer.

    The Functional Medicine approach treats autoimmune diseases by looking at the underlying factors that lead to the immune system being deregulated. These factors can include disease processes such as leaky gut, food sensitivities, toxins, mold, heavy metals, nutritional deficiencies, infections, etc. Functional Medicine looks at the best strategies for correcting this by identifying the cause and catalyst of those agents.

    Once you identify the cause and remove the factors that negatively affect the G.I. and immune system, a strategy to intervene can be formed. A nutritional strategy to repair and restore the gut is recommended. By reestablishing the mucosa tolerance and re-balancing the bacterial landscape, gut health is rebuilt and the immune system can function and respond unimpaired.

    The podcast will cover these topics in more depth and detail. You will learn more about how toxins behave. For example, how BPA and heavy metals found in plastics insert itself in the metabolic pathway and disrupt it by misplacing nutrients. You will also learn how to test for autoimmune disease and learn the role infections play in increasing our risk. More importantly, you will learn how to improve your health and nutritional deficiencies.
