Rational Wellness Podcast

Dr. Michael Aziz on Targeting Aging: Diet, Fats, Testing, Hormones, Peptides, and Practical Longevity Strategies Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews Dr. Michael Aziz about longevity and treating aging as a modifiable biological "syndrome," referencing the hallmarks of aging and the need for broad approaches because organs age at different rates. Aziz highlights major aging accelerators—processed foods, refined carbs/sugar, seed oils, poor sleep, and stress—criticizes low-fat guidelines and the Seven Countries study, and argues saturated fats (e.g., butter, coconut) are not the main driver of heart disease, which he frames as inflammation and oxidized/sticky cholesterol, emphasizing advanced lipid testing. He outlines a basic longevity lab panel (A1C, fasting insulin, hs-CRP, liver tests, advanced lipids) and discusses insulin resistance, GLP-1 drugs and side effects, muscle preservation, exercise/HIIT, and dietary moderation of grains and keto-style choices without processed meats. The conversation covers hormones, bioidentical replacement, peptides, senolytics (fasting, fisetin, quercetin, low-dose naltrexone), NAD/NR/NMN, supplements, sauna, tadalafil, metformin, and berberine. 00:59 Meet Dr Michael Aziz 02:51 Is Aging a Disease 04:14 Hallmarks of Aging 04:54 Measuring Biological Age 05:56 Biggest Aging Accelerators 06:18 Diet Pitfalls Sugar Oils 07:54 Keto Done Right 08:59 Saturated Fat Debate 12:37 Cooking Fats and Seed Oils 14:19 Low Fat Guidelines Myth 15:06 Vegetarian Diet Concerns 16:27 What Really Causes Heart Disease 18:01 Longevity Lab Testing 18:33 Insulin Resistance and GLP1s 19:31 GLP1 Side Effects 20:42 Muscle Mass for Longevity 21:08 Omega 6 Ratio Explained 22:21 Coconut Oil and Cholesterol 24:20 Perfect 10 Diet vs Keto 25:43 Whole Grains and Mediterranean Diet 27:52 Grains And Gluten 28:54 Mediterranean Vs French Diet 29:59 Dairy Benefits And Risks 30:39 Hormones And Aging 31:43 Peptides For Longevity 34:28 Senescent Cells And Senolytics 36:08 Fasting Strategies Explained 37:43 NAD NR And NMN 39:23 Supplements And Mitochondria 41:04 Overhyped Longevity Treatments 43:08 Metformin Berberine And Sugar 45:27 Exercise For Longevity 47:00 Future Of Anti Aging Medicine 48:37 Mediterranean Diet Revisited 50:42 Final Takeaways And Where To Find Him 51:47 Podcast Wrap Up And Next Steps Dr. Aziz is a board-certified internal medicine physician, author, and broadcast media commentator.

The HRT Questions Most Women Never Get Answered with Karen Martel | Rational Wellness Podcast 481

Perimenopause to Menopause: Testing, Progesterone First, and Evidence-Informed HRT with Karen Martell Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews hormone specialist Karen Martell about perimenopause and menopause, emphasizing that midlife hormonal shifts affect metabolism, sleep, mood, cognition, bone and cardiovascular health. Martell says perimenopause can begin in the mid-30s, often with declining progesterone from less frequent ovulation, leading to heavy periods, insomnia, anxiety, and perceived "estrogen dominance," while estrogen later becomes erratic and then declines toward menopause around age 51. She critiques common responses like birth control, hysterectomy, and symptom-only medications, and recommends combining bloodwork with saliva or urine metabolite testing (e.g., DUTCH) when cycling. For HRT, she prefers transdermal estradiol over oral estrogen, discusses progesterone delivery options and sensitivities to oral metabolites, addresses testosterone (often compounded; injectable preferred), and notes roles for DHEA and pregnenolone. She also covers vaginal therapies, dosing based on both symptoms and protective lab ranges, and cautious later-life initiation. 00:00 Show Intro and Mission 00:59 Why Midlife Hormones Matter 02:23 Perimenopause Starts Early 03:18 Progesterone Drop Signs 06:17 Testing Hormones and Thyroid 08:02 Bad Advice and Quick Fixes 09:33 When Supplements Aren't Enough 10:52 Starting Progesterone Therapy 12:49 Best Hormone Testing Methods 15:36 Endocrine Disruptors Cleanup 17:40 Choosing Estrogen Delivery 18:43 Pellets and Testosterone Risks 22:27 Progesterone Forms and Dosing 25:21 Why Avoid Oral Estrogen 27:00 Estradiol for Life 27:38 Estriol vs Estradiol 30:23 Patch vs Cream Dosing 31:56 E4 Estrogen Debate 33:39 Cycling Progesterone 35:38 DHEA and Pregnenolone 37:39 Vaginal Hormone Options 40:18 Optimizing HRT Levels 43:52 Starting HRT After 70 47:45 Perimenopause Timing Tips 50:19 Where to Find Karen

What are the Functions of Microbial Gases, Hydrogen, Methane, & Hydrogen Sulfide with Dr. Tom Fabian | Rational Wellness Podcast 480

Gut Microbial Gases Beyond SIBO: Hydrogen, Methane, and Hydrogen Sulfide as Signaling Metabolites Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews Dr. Tom Fabian, PhD, to discuss gut microbial gases beyond the usual SIBO framing. They explain that hydrogen, methane, and hydrogen sulfide are normal microbial metabolites with potential signaling roles, alongside key microbiome products like short-chain fatty acids (especially butyrate), which fuels colon cells, supports tight junctions, regulatory T cells, and helps maintain an anaerobic colon environment. Fabian notes metabolomics (e.g., GI-MAP stool add-ons) can provide functional insight beyond which microbes are present, highlighting butyrate producers such as Faecalibacterium and Roseburia. They review controversies in breath testing interpretation, discuss methane biology and debated links to constipation, and emphasize emerging research that hydrogen sulfide is widely produced (often from cysteine metabolism), supports colon mitochondria and anaerobiosis, may relate to stress responses and longevity, and that excessive sulfur restriction may be misguided; fiber and polyphenols may mitigate protein-driven hydrogen sulfide. 00:00 Show Intro 00:59 Why Gut Gases Matter 04:04 Microbiome Metabolites 05:52 Butyrate Deep Dive 09:07 Measuring SCFAs 13:20 Hydrogen and Breath Tests 19:12 Hydrogen Benefits 28:19 Methane and Motility 31:06 Sponsor Break 32:13 Methanogens Explained 35:24 Hydrogen Sulfide Science 50:59 Clinical Takeaways

Environmental Toxins, Wildfire Smoke, and Practical Detox Strategies with Dr. Joe Pizzorno Dr. Ben Weitz hosts the Rational Wellness Podcast and interviews Dr. Joe Pizzorno on latest research about environmental toxins, emphasizing wildfire smoke risks, PM2.5 penetration, rapid body and brain distribution, and links to neurological, respiratory, and cardiovascular disease. Pizzorno argues toxins are a primary, solvable driver of chronic illness and that oxidized cholesterol reflects toxic exposure more than cholesterol itself. Practical protections include running high-MERV (≥12, ideally 16) HVAC filtration 24/7, avoiding incense, and supporting detox with glutathione (liposomal or via NAC), increased and diverse fiber to reduce toxin reabsorption, and saunas to sweat profusely (except PFAS "forever chemicals," which don't excrete via sweat). They discuss mercury release from forest fires, microplastics and gut binding, arsenic reduction from rice cooking, water filtration (carbon block, RO for arsenic), endocrine disruptors like bisphenols, and toxin assessment using GGTP, ALT, eGFR, and urinary 8-OHdG rather than challenge tests. 01:02 Meet Dr Joe Pizzorno 02:24 Wildfires and Toxic Exposure 05:21 PM2.5 and Systemic Damage 07:24 Cholesterol Oxidation and Toxins 09:35 Home Air Filtration Tips 11:25 Mercury From Forest Fires 13:15 Glutathione and NAC Basics 14:41 Binders and Fiber Strategy 17:26 Persistent vs Nonpersistent Toxins 19:21 Saunas and Forever Chemicals 21:47 Microplastics and Gut Binding 24:13 Post Fire Cleanup Safety 25:21 Arsenic in Water Rice Chicken 27:54 Whole House Water Filters 29:08 Chlorine Fluoride Tradeoffs 31:08 Plastic Bottles and Bisphenols 31:54 Endocrine Disruptors Explained 33:58 Phytoestrogens vs Xenoestrogens 35:49 Safer Drinkware and Cookware 36:37 Testing Toxins Smarter 39:49 Biomarkers GGTP ALT eGFR 44:37 Detox Nutrition and Glutathione 46:54 Toxins and Autoimmune Disease 48:22 Cure Versus Suppression 53:44 Final Thoughts and Outro

Dr. David Perlmutter on Microglia, Metabolism, and a New Paradigm for Neurodegenerative Disease

Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews neurologist and author Dr. David Perlmutter about his upcoming book, Brain Defenders, describing a neuroscience shift from neuron-centered thinking to the brain's immune cells (glia/microglia) as key drivers of neurodegeneration. Perlmutter argues microglial polarization (supportive M2 vs destructive M1) is upstream of protein accumulations like beta-amyloid, alpha-synuclein, and phosphorylated tau, and is strongly influenced by lifestyle-driven metabolic health (blood sugar, insulin resistance, lipids, blood pressure), systemic inflammation, gut dysbiosis, and blood–brain barrier integrity. They discuss prevention, multimodal treatment approaches (e.g., Bredesen and Ornish/Tanzi), mitochondrial dysfunction, exercise, supplements (olive oil polyphenols, vitamin D, CoQ10, urolithin A, spermidine, dihydromyricetin, rosmarinic acid), and emerging drug strategies including TREM2 targeting and GLP-1 agonists, noting benefits and risks.

Rational Wellness Podcast Episode 020: Female Hormones with Dr. Jill Stocker Dr. Jill Stocker discusses the use of bioidentical estrogen and progesterone hormones to help women restore their youth and vigor and their "juiciness". I laid out the topic first by talking about how it was believed for decades that estrogen was protective for the heart, which is why women have a lower risk of heart attack than men until menopause and then their risk increases equal to men's. There was however, concern about the increased risk of breast and ovarian cancer. When the Women's Health Initiative study was published in 2002 it shook the field of women's hormone replacement therapy by demonstrating an increased risk of heart attack and stroke in women who took equine (from horses) estrogen and synthetic progestins (Premarin and PremPro). But these results do not necessarily apply to the use of bioidentical hormones, which are much safer.

Mold, Indoor Air Quality, and Building a Healthy Home with Michael Rubino Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews mold remediation and indoor air quality expert Michael Rubino of Home Cleanse and the Change the Air Foundation about mold, indoor air quality, and creating a healthy home. Rubino describes entering the field after Hurricane Sandy, observing people remaining ill despite cosmetic restorations driven by insurance limits and cost-cutting, and notes an EPA statistic that people spend about 90% of their time indoors. They discuss widespread water damage in homes, mold and bacteria as linked problems, and how new construction can develop mold from poor material handling and inadequate moisture control. Rubino addresses wildfire-related indoor contamination (heavy metals, VOCs, ash), recommends dust and VOC testing, critiques fogging and bleach-based approaches, emphasizes HVAC maintenance and filtration, and outlines the foundation's education, research, and policy goals.

Dr. Philip Goglia explains to Dr. Ben Weitz how to improve athletic performance through nutrition.

Podcast Details

Dr. Goglia explained that using the correct macronutrient food pattern that fits each person's metabolism is crucial. This can be determined via a questionnaire and by looking at a lipid profile. If you are efficient at burning fats and carbohydrates and you consume a vegan diet, it will not work very well. Some people are efficient at burning fats and proteins, some are efficient at burning carbs, and some are efficient at both.

Dr. Goglia will often utilize a pretraining cocktail with athletes that includes D-Ribose, L-Glutamine, Taurine, Cinnamon, Calcium and Magnesium, and blackstrap mollases. We'll even add citrulline mallate to it. He mentions that when his athletes have an athletic event in the morning, he will have the athletes eat a "mash" in the evening that includes shredded wheat, apple sauce, almond butter and jam. They'll wake up with lots of energy. He may also have the athlete consume this "mash" several hours before an athletic event, such as a basketball game or an athletic event.

The Science of Breathwork with Dr. Sachin Patel | Rational Wellness Podcast

Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews Dr. Sachin Patel, a chiropractor and functional medicine practitioner known for breathwork, about how breathing influences health. Patel explains how tongue posture and nasal breathing affect facial structure, airway size, posture, circulation, lymph flow, and nervous system regulation, and discusses CO2 tolerance, the Bohr effect, and how hyperventilation can reduce oxygen delivery. He outlines common mistakes such as treating breathwork as a single daily session instead of frequent check-ins, and emphasizes nose breathing—especially during sleep—citing high rates of mouth breathing and recommending options like micropore tape or Myotape. They cover breathing "gears" for exercise, parasympathetic-focused patterns (including 4-7-8 and longer exhales), breath holds, digestion and vagal tone, sleep apnea considerations, and resources including Patel's sites and book. 00:00 Show Intro 00:59 Meet Dr Sachin Patel 01:59 Why Breathwork Matters 05:32 Tongue Posture Airway 09:47 Diaphragm Heart Lymph 13:25 CO2 Tolerance Bohr Effect 19:07 Daily Breath Habits 22:00 Mouth Taping Sleep 25:06 Nasal Breathing Benefits 29:19 Athletes Three Breathing Gears 33:22 Breathing Metabolism Fat Loss 35:07 Question About 478 35:17 Exhale For Sleep 36:14 Breath And Trauma 40:21 Somatic Breathwork 41:05 Why Mouth Breathing 42:46 Breath And Digestion 48:08 Breath Holds Benefits 50:11 Breathing For Longevity 51:23 Clinicians Start Here 53:32 Sleep Apnea Alternatives 57:31 Final Takeaways 01:01:21 Diaphragm And Rhythm 01:03:48 Heart And Blood Pressure 01:04:49 Where To Learn More 01:06:58 Podcast Wrap Up

Dr. Chris Shade on Peptides, Liposomal Delivery, and Supporting GLP-1 Therapy

Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews Dr. Chris Shade, founder and CEO of QuickSilver Scientific, about peptides and oral liposomal delivery. Shade defines peptides as short amino-acid chains with signaling roles and explains how high-quality, small-particle, injectable-grade phosphatidylcholine liposomes enable intraoral absorption of water-soluble compounds like glutathione and certain peptides. They discuss BPC-157 for gut lining and broad tissue repair; KPV for inflammatory modulation (including Crohn's flares) via NF-kappa B and cytokine control; copper GHK for extracellular matrix/skin and connective-tissue support (including Ehlers-Danlos); and TB-500 for more angiogenic, muscle-oriented repair, often stacked with BPC and GHK ("Wolverine Stack"), with cycling and empty-stomach dosing. Shade also covers Epitalon and Thymulin for sleep, telomerase/telomeres, and immune balance, and outlines protocols to make GLP-1 drugs safer using bitters, binders, Lipotone, GLP-1 Amplifier, and nutritional/mineral support, while noting GI, bile-flow, and muscle-loss concerns.

New Research and Clinical Updates on SIBO: Methane, Hydrogen Sulfide, Elemental Diet, Herbs, Probiotics, and Testing with Dr. Allison Siebecker

Dr. Ben Weitz interviews Dr. Allison Siebecker on major updates in understanding and treating SIBO/IMO, drawing from new DDW conference findings. Highlights include a methane-targeting enzyme inhibitor drug (CS06) that rapidly lowers methane without acting as an antibiotic; a delayed-release NAC plus rifaximin formulation that improves outcomes and may allow lower rifaximin dosing; and a new elemental diet formulation (MBiota) reported to reach up to 100% eradication in one study and improve IBS symptoms. They discuss a new herbal study on GI Ally (allicin, neem, pomegranate) using FoodMarble for frequent gas tracking, plus emerging FoodMarble research (low FODMAP adherence, menstrual-cycle effects on methane). Additional topics include a probiotic/prebiotic review suggesting higher success rates, Iberogast's reported prebiotic/anti-inflammatory effects, breath-test validation via endoscopic gas sampling, interpretation nuances for constipation and methane thresholds, GLP-1–associated SIBO risk and testing challenges, and links among SIBO, histamine intolerance, mold illness, and motility strategies.

PCOS Renamed PMOS: Root Causes, Hormones, Metabolism, Labs, and Integrative Treatment with Dr. Felice Gersh

Dr. Ben Weitz introduces an interview with OB-GYN and integrative physician Dr. Felice Gersh on PCOS, newly renamed polyendocrine metabolic ovarian syndrome (PMOS) per a May 12, 2026 Lancet announcement, meant to shift focus from "cysts" to hormonal and metabolic dysfunction. Gersh argues ovaries remain central, describing impaired aromatization leading to low estradiol, high LH-driven testosterone, and downstream effects including insulin resistance, inflammation, leaky gut, altered microbiome, sympathetic activation, elevated cortisol/DHEAS, obesity, mood disorders, sleep apnea, and autoimmune risk. They discuss legacy and practical issues with renaming, updated diagnostic criteria adding anti-Müllerian hormone in adults, and PMOS as a diagnosis of exclusion. Recommended evaluation includes total testosterone, DHEAS, SHBG, thyroid panel with antibodies, lipids including apoB, hsCRP, nutrients, ANA, prolactin, and select rule-outs (17-OHP, Cushing's, tumors). Treatment emphasizes lifestyle, plant-focused diet, time-restricted eating, exercise, supplements (myo-inositol, NAC, quercetin, melatonin, mitochondrial support), cautious pharmaceuticals (metformin/berberine, spironolactone), and cyclic bioidentical estradiol/progesterone; low-dose dexamethasone is noted for select adrenal-driven cases.
