Innate–Adaptive Balance and BWH 85 Beta-Glucan with Functional Medicine Physician Dr. Rob Rountree: He brings a nuanced view of immunity that rejects the simple “immune boosting” dimmer-switch model and emphasizes immune regulation and readiness. He reviews innate immunity as sentinel cells using pattern recognition receptors (e.g., macrophages) and explains how innate and adaptive systems interface, with innate signaling training adaptive responses; chronic inflammatory disease is framed as rooted in innate dysregulation. He reveals how immune responses can both protect and harm (candida, cytokine storm concerns during COVID) and why test-tube “stimulation” doesn’t equal human effects. The focus is a purified brewer’s yeast (Saccharomyces cerevisiae) beta-1,3/1,6-glucan (BWH 85, 85% purity), its triple-helix structure, receptors (Dectin-1, CR3), dosing (100–500 mg), evidence for improving vaccine response in elders, and potential relevance for autoimmunity, athletes, and cancer surveillance alongside lifestyle and key nutrients like vitamins A, C, D and zinc.

Dr. Hoffman continues his conversation with functional medicine practitioner Robert Rountree, MD, medical director of Boulder Wellcare, in Boulder, Colorado, and long-time educator at the Institute for Functional Medicine.

Dr. Ross Pelton, Director of Science & Education for Essential Formulas Incorporated, maker of Dr. Ohhira’s premium probiotic products, reveals how the gut microbiome affects metabolism, appetite, weight regulation, and overall health. He emphasizes the importance of microbiome diversity, supported by eating a wide variety of plant foods rich in fiber and polyphenols, and discusses how fermented foods and postbiotic metabolites help maintain a healthy gut environment. Pelton explains Dr. Ohhira’s multi-year fermentation process and the idea that postbiotics may be key health regulators. He reviews studies suggesting benefits from Dr. Ohhira’s probiotics for athletic performance markers, reduced fatigue, and improved bowel regularity, and notes research showing antibiotic-related losses in gut diversity can persist for years. He also mentions a higher-dose “Reset Challenge,” a postbiotic paste concentrate, and an ME-3 product aimed at increasing glutathione.

Nutritionist Leyla Muedin answers a listener question about taking many supplements with oolong tea, explaining that tea tannins can interfere with vitamin and mineral absorption; because oolong is partially oxidized, its tannin level falls between green and black tea, so she recommends taking supplements with water and separating them from tea or coffee by at least an hour (ideally 1.5–2 hours). She then reviews research in Nature Communications from USC on how gut signals via the vagus nerve may influence which food experiences become memories: in rats, nutrient-rich foods increased acetylcholine signaling to the hippocampus, supporting memory for food location, while sweetness without calories did not. Over time, high-fat/high-sugar diets weakened this gut–hippocampus communication and memory performance, with implications for obesity, diabetes/prediabetes, and cognitive decline, and possible future vagus-nerve-based approaches.

Former pharma reporter for the New York Times and the Wall Street Journal, investigative reporter Gardiner Harris, discusses his new book “No More Tears: The Dark Secrets of Johnson and Johnson.” It details the unethical practices and numerous scandals that have plagued Johnson & Johnson over the decades, including the asbestos contamination in baby powder, the misuse of the antipsychotic drug Risperdal, the dangerous outcomes of vaginal mesh implants, and the controversial development and deployment of their COVID-19 vaccine. Harris provides a comprehensive overview of the corporate malfeasance within the pharmaceutical giant, shedding light on the regulatory failures and systemic corruption that have allowed these issues to persist.

Renowned integrative medicine physician, board-certified internist, and researcher Dr. Jacob Teitelbaum discusses his new book, "Pain Relief in 4 Simple Steps," and the growing chronic pain epidemic (one in four U.S. adults; about 7% debilitating). Teitelbaum argues most pain is treatable by addressing root causes and describes four biochemical pain types—muscle pain from low energy, inflammatory pain, neuropathic pain, and brain pain (microglial activation)—alongside structural, biophysical, and mind-body contributors. They discuss risks of NSAIDs and Tylenol, diet’s role (processed foods, sugar, seed oils), and strategies such as an Energy Revitalization Drink Mix, SHINE protocol, curcumin with turmeric oils plus boswellia (Curamin), omega-3 support, magnesium, B12 issues with metformin/GLP drugs, lipoic acid for neuropathy and burning mouth syndrome, and migraine support with high-dose riboflavin and magnesium. He also cover CRPS treatments (including ketamine and bisphosphonates), low-dose naltrexone and PEA, compounded topical options, and pelvic pain/prostatitis approaches including quercetin and antibiotics like fosfomycin when appropriate.

Dr. Hoffman continues his conversation with integrative medicine physician, board-certified internist, and researcher Dr. Jacob Teitelbaum about his new book, "Pain Relief in 4 Simple Steps."

Exercise, Recovery, Relaxation—and Muscle as the Key to Healthy Aging: Nutritionist Leyla Muedin discusses science-backed wellness trends that pair exercise with effective recovery and deliberate relaxation to support performance, resilience, and healthy aging, noting benefits such as fewer overuse injuries, better sleep, steadier energy, and improved adherence. She highlights relaxation practices (breathwork, meditation, gentle yoga, outdoor time, massage, consistent sleep routines) and encourages making recovery part of daily life, including creating home or community “wellness spaces” like pools for gentle movement and stress reduction. She emphasizes sustainable habits supported by tools like wearables and heart-rate variability tracking. The episode then frames muscle as a “longevity secret weapon,” explaining its roles in metabolism, glucose storage, insulin sensitivity, inflammation control, and joint stability, citing the PURE study on grip strength and mortality, warning about sarcopenia, and recommending strength training, higher and well-distributed protein intake with age due to anabolic resistance, plus adequate sleep and recovery.

Dr. Sharon Bergquist is an award-winning physician, innovative healthcare leader, and visionary researcher, renowned for spearheading a science-based approach to applying lifestyle as medicine. She is the author of "The Stress Paradox: Why You Need Stress to Live Longer, Healthier, and Happier." She discusses the misunderstood role of stress, emphasizing its potential benefits when managed and utilized correctly. Dr. Bergquist explains how stress can enhance cellular function, boost resilience, and improve overall health. She delves into topics such as the physiology of stress, the science of hormesis, and the benefits of controlled stressors including plant toxins, thermal exposure, fasting, exercise, and psychological challenges. The discussion underscores the importance of balancing stress and recovery to promote cellular repair and long-term well-being.

Food as Medicine: Why Medical Nutrition Therapy and Medically Tailored Meals Belong in Modern Healthcare: Registered dietitian nutritionist Leyla Muedin argues that food should be treated with the same rigor as medication through medical nutrition therapy (MNT) and “diet prescriptions,” integrating nutrition into treatment plans rather than leaving it as optional advice. She cites evidence that medically tailored meals (MTMs) can improve outcomes and reduce costs, including a Health Affairs simulation estimating $23.7B in first-year net savings nationwide and a Nature Medicine analysis of a Massachusetts Medicaid demonstration (2020–2023) showing MTM recipients had 31% fewer hospitalizations, 20% fewer emergency visits, and $3,433 lower total healthcare costs, offsetting 98% of program costs. She discusses food insecurity, expanding Medicaid coverage via Section 1115 waivers, EHR integration, and how MTMs support adherence for conditions such as diabetes, cardiovascular disease, chronic kidney disease, depression, and IBS (including low FODMAP).

Supplements and Morning Coffee: Timing Iron, Zinc, Calcium, B Vitamins, and Vitamin D: Nutritionist Leyla Muedin explains that coffee (and tea) can interfere with nutrient absorption and digestion, so certain supplements shouldn’t be taken with morning coffee. Coffee’s tannins and polyphenols can significantly reduce non-heme iron absorption (decaf doesn’t prevent this), and similar binding issues may affect zinc; she recommends taking iron with water at least 1–2 hours away from coffee and pairing it with vitamin C. Because caffeine may increase urination, B vitamins (especially thiamine) may be lost more readily, so she suggests taking them with food but not with coffee. Vitamin D is best taken with a fat-containing meal (not washed down with coffee), and calcium supplements should be separated from coffee since caffeine can slightly increase calcium loss. She also notes interactions such as green tea reducing folate absorption, spinach oxalates limiting mineral absorption, phytates in bran/legumes reducing iron and zinc absorption, and calcium (milk or supplements) cutting iron absorption, emphasizing timing rather than eliminating these foods.

Natalie Ochoa, president of Jigsaw Health, details widespread magnesium insufficiency and why it occurs (soil depletion, low plant intake/processed foods, stress-related loss, aging, and medication effects including diuretics and proton pump inhibitors). They discuss the poor reliability of standard serum magnesium testing, the limitations of RBC magnesium testing, and using symptoms such as cramps, twitches, constipation, fatigue, and sleep trouble as clues. Ochoa explains Jigsaw’s sustained-release magnesium malate (MagSRT) designed to reduce GI side effects and how to read labels for elemental magnesium, with typical intake around 500 mg/day. She reviews the 2018 placebo-controlled Scottsdale Magnesium Study (91 participants) showing increases in RBC and serum magnesium and reduced deficiency symptoms, and a Korean study linking higher magnesium intake to less sarcopenia and lower CRP. They also cover MagSoothe (magnesium glycinate) and an Oura Ring-based sleep trial reporting reduced perceived stress and improved sleep quality, plus mention Jigsaw’s potassium drink, electrolyte product, and cod liver oil.

Dr. Hoffman continues his conversation with Natalie Ochoa, president of Jigsaw Health.

Cardiologist and electrophysiologist Dr. Gregory Marcus, chair of the American Heart Association scientific statement writing group, reveals evidence on coffee/caffeine and cardiovascular health. He discusses how earlier assumptions that caffeine triggers arrhythmias are complicated by genetics, individual risk factors, and mostly observational research. Marcus reviews randomized and observational findings: the CRAVE trial showed no increase in premature atrial contractions but more premature ventricular contractions on coffee days; a trial in post-cardioversion patients found less atrial fibrillation with daily coffee. Observational data suggest lower risks of type 2 diabetes, heart attack, stroke, and AFib among coffee drinkers, while heart failure risk may be lower at low intake but higher around 4–5 drinks/day. He cautions against extrapolating benefits to energy drinks, discusses additives like sugar, touches on alcohol, cannabis, Mediterranean/DASH diets, pollution, and evolving AFib treatments, wearables, and pacing/ablation technologies.

Dr. Hoffman continues his conversation with cardiologist and electrophysiologist Dr. Gregory Marcus, chair of the American Heart Association scientific statement writing group.

Managing High Homocysteine with MTHFR Variants and the Role of Vitamin C in Brain Aging: Registered dietitian nutritionist Leyla Muedin discusses MTHFR genetic variants (C677T and A1298C), their links to impaired methylation, homocysteine, SAMe, mood issues, migraines, vitamin deficiencies, and pregnancy complications, noting many people are asymptomatic and some feel worse on methylated B vitamins and do better on standard formulations. Responding to a listener with C677T, high homocysteine, and borderline methylmalonic acid, she reviews optimal homocysteine targets and outlines other causes of elevated homocysteine such as hypothyroidism/subclinical hypothyroidism, kidney failure, obesity, hypertension, diabetes, smoking, inactivity, and medications (atorvastatin, methotrexate, fenofibrate). She suggests checking these factors, considering absorption issues (intrinsic factor) for B12, and trialing SAMe and more trimethylglycine, with possible pharmacologic folate if needed. She then summarizes an observational Japanese study (n=2,044 adults >64) linking lower plasma vitamin C to reduced gray matter and weaker default mode network connectivity, and notes diet and blood sugar can affect vitamin C status.

Chemical engineer and MoldCo founder Ariana Thacker discusses mold-related illness, including chronic inflammatory response syndrome (CIRS), as a major blind spot in conventional care for chronic, multi-system symptoms. Thacker recounts developing rapid-onset brain fog, slurred speech, GI issues, hair loss, weight gain, and shortness of breath after six and a half months in a moldy Miami apartment, seeing over a dozen specialists who attributed symptoms to stress or anxiety. They discuss exposures beyond allergy (mycotoxins, VOCs, microbial fragments), genetic susceptibility (HLA haplotypes), and prevalence estimates tied to water-damaged homes. The episode covers home detection (sensory/visual checks, humidity, dust PCR/ERMI testing, certified inspectors) and diagnostics/treatment via Shoemaker-related biomarkers and protocols, including low-starch diet guidance and VIP peptide therapy, plus MoldCo’stesting and virtual care services.

Lowering A1C in Prediabetes and Using Less Insulin on a Low-Carb Diet: Leyla Muedin, a registered dietitian nutritionist, answers listener questions about blood sugar and insulin. Responding to Rita, whose hemoglobin A1C rose from 5.6 to 5.8, Layla says “glucose hacks” to blunt carb absorption aren’t appropriate at that level and recommends a strict very low-carb/keto approach (under 25 grams of total carbs per day), avoiding sugar, starchy vegetables, fruit (except avocado), sweetened beverages, and even alternative sweeteners and low-carb processed products; she suggests retesting A1C after three months and avoiding testing during illness or inflammation. She also addresses Joy, a type 1 diabetic, affirming low-carb eating to reduce insulin needs and weight gain, criticizing an insurance pricing structure that charges more when insulin is used more slowly, and expressing concern about doctors prescribing insulin too quickly for type 2 diabetes instead of dietary intervention.

Dr. Julie Siemers, a nurse educator and author of “Surviving Your Hospital Stay: A Nurse Educator's Guide to Staying Safe and Living to Tell About It,” details the importance of patient safety in hospitals, the dangers of medical errors, and how patients and their families can advocate for better care.

Precision Hormone Health: Testosterone, Menopause, Muscle, Sleep, and Proactive Longevity: Endocrinologist Dr. Florence Comite details her book “Invincible: Defy Your Genetic Destiny to Live Better, Longer” and her precision-medicine approach to proactive longevity. She discusses testosterone decline beginning in the 30s in both sexes, stress-related low T (including in special forces), and testosterone’s roles in energy, cognition, motivation, muscle, bone, and chronic disease risk. Comite argues genes are a “draft” and health destiny can be altered through epigenetic-like choices, individualized data, and early monitoring. For women, she emphasizes estrogen, progesterone, and testosterone in perimenopause/menopause, preferring bioidentical hormones and criticizing WHI’s use of Premarin/Provera and older participants. She covers osteoporosis prevention, muscle as an “organ of longevity,” protein intake, resistance training, continuous glucose monitors for individualized diet, sleep quality tracking via wearables, and selective use of DHEA, pregnenolone, growth hormone pathways, and peptides with attention to sourcing and risk.

Dr. Hoffman continues his conversation with endocrinologist Dr. Florence Comite.

Leyla Muedin, a registered dietitian nutritionist in New York City, discusses the growing shift from symptom-only “sick care” to a clinically grounded holistic approach to health and recovery. She argues that self-guided wellness routines can leave gaps when underlying medical issues, mental health conditions, substance use disorders, or trauma remain unaddressed, and emphasizes integrating evidence-based clinical evaluation (including labs and deficiency testing) with lifestyle practices. She explains how treating symptoms in isolation misses connections (e.g., stress, sleep, grief) and defines true holistic care as addressing physical, mental, emotional, relational, environmental, and purpose-related factors without rejecting medical treatment. Key components include consistent movement, individualized nutrition built on basics, nervous system regulation (sleep, nature, breathing, meditation/prayer), meaningful social connection, and a sense of purpose as clinically relevant to resilience.

Naturopathic gastroenterologist Mark Davis, ND (FABNG), discusses his work in fecal microbiota transplantation (FMT), research, and integrative approaches to GI disease. Davis explains FMT history, screening criteria, delivery methods, how it differs from probiotics, and why it is highly effective for recurrent C. difficile (about a 90% durable cure), while noting FDA-approved products (Rebyota, Vowst) and off-label applications. He describes IRB-approved studies on naturopathic care for IBS and ulcerative colitis and a blinded project comparing consistency across 15–20 stool microbiome labs. The conversation covers evidence for diet in IBS/IBD (including SCD and a semi-vegetarian diet), low-FODMAP as a temporary tool, breath testing and relapse in SIBO, helminthic therapy options and legality, targeted probiotics (Saccharomyces boulardii, Akkermansia, soil-based species), enema therapies, indigo naturalis benefits and risks, saffron evidence for mood, telemedicine practice, and a crowdfunding platform for clinical trials.

Dr. Hoffman continues is conversation with naturopathic gastroenterologist Mark Davis, ND (FABNG).

Psychedelic Therapy for Mental Health: Research, Safety, and the Path to FDA Approval: Dr. Will Van Derveer and Keith Kurlander, co-authors of “Psychedelic Therapy: A Revolutionary Approach to Restoring Your Mental Health and Reclaiming Your Life,” reveal the shift from recreational psychedelics to structured, research-based psychedelic-assisted therapy for conditions like PTSD, depression, and anxiety. Van Derveer describes limitations of conventional psychiatry (citing STAR*D remission rates) and his entry into MDMA-assisted PTSD research after promising results. They contrast controlled clinical protocols—screening, preparation, safe setting, trained facilitation, medical monitoring, and post-session integration—with uncontained recreational use. The discussion covers current policy momentum under Trump and RFK Jr., VA interest for veterans, and key agents: ketamine (including abuse risks and clinic-only Spravato), MDMA (phase 3 but not approved in 2024), psilocybin (phase 3, potential FDA approval), LSD (GAD trials), ibogaine (arrhythmia risk, Mexico clinics), ayahuasca, peyote, and microdosing. They also note commercialization, including Eli Lilly’s acquisition of a 5-MeO-DMT nasal spray developer, and emphasize an integrative “all-of-the-above” mental health approach.

What Triggers Age-Related Belly Fat? New Stem Cell Findings and a Nutrition Perspective: Nutritionist Leyla Muedin discusses research from City of Hope (published in Science) on why belly fat increases with age even without major weight gain, emphasizing the health risks of visceral fat as an endocrine organ linked to inflammation, diabetes, heart disease, and accelerated aging. The study suggests aging activates adipocyte progenitor cells (APCs) and produces an age-specific stem cell population called committed preadipocytes (CP-As) that generate new fat cells, with experiments showing older APCs create more fat cells even when transplanted into young mice. Single-cell RNA sequencing identified greater CP-A activity in middle-aged mice and similar cells in higher numbers in middle-aged human tissue. Researchers implicate the LIFR signaling pathway and propose future therapies to block these cells, while Leyla questions root causes and argues metabolic dysfunction—insulin resistance, hyperinsulinemia, high carbohydrate intake, and sedentary behavior—should be addressed nutritionally rather than via a pill.

The Brain–Body Connection, Gut Health, Stress, and Medical Gaslighting: board-certified psychiatrist Dr. Susan Trachman, author of “It’s Not Just In Your Head,” about psychosomatic medicine and the two-way brain–body connection. Trachman explains how patients with complex symptoms are often dismissed as having “medically unexplained symptoms” and discusses medical gaslighting, especially affecting women and people of color, with examples of missed diagnoses. She describes how inflammation, the gut microbiome, leaky gut, diet, probiotics, fermented foods, and even fecal transplants can influence mood and health, and reviews vagus nerve stimulation research. The conversation covers stress effects, including Takotsubo “broken heart” cardiomyopathy, CBT for anxiety, IBS, and pain, the role of sleep and the brain’s glymphatic system, pandemic-related mental health and long COVID symptoms, concerns about GLP-1 drugs causing emotional flatness, and careful SSRI tapering to avoid withdrawal.

Vitamin B12 Deficiency--The “Aging” Symptoms You Shouldn’t Ignore: Leyla Muedin, a registered dietitian nutritionist in New York City, discusses vitamin B12 deficiency as a common problem that can mimic normal aging, noting adults need only about two micrograms daily to support red blood cells, nerves, and DNA. She reviews the history of liver treatment for pernicious anemia and explains that deficiency remains common in older adults, vegans/vegetarians, and people with impaired absorption due to low stomach acid, autoimmune gastritis, weight loss surgery, or medications such as metformin and proton pump inhibitors. Symptoms can develop slowly and include fatigue, weakness, shortness of breath, numbness/tingling, poor balance, memory issues, and brain fog; she advises medical evaluation and B12 testing rather than assuming aging or relying on wellness-clinic injections when levels are normal. She emphasizes B12 is primarily in animal foods, so vegans need supplements, and notes broader nutrient shortfalls she sees in vegan clients.

Dr. David Chernoff, Chief Medical Officer of Setpoint Medical, discusses electrically driven vagus nerve stimulation (VNS) as a “neuroimmune modulation” approach to autoimmune and inflammatory disease. Chernoff explains the vagus nerve’s sensory role in monitoring organs and signaling the brainstem and spleen to regulate immune responses, and how precise stimulation can reduce pro-inflammatory cytokines without immunosuppression. Setpoint’s miniaturized, wireless, MRI-compatible implant is placed in an outpatient 45-minute neck procedure and delivers one minute of daily stimulation titrated to an upper comfort level; long-term safety is supported by prior surgical experience and a 242-patient blinded RA study with two-year data, leading to FDA approval for rheumatoid arthritis. The discussion covers add-on use with medications, potential steroid tapering, reimbursement, and research in Crohn’s disease, relapsing MS (vision and remyelination), and other conditions, including psoriatic arthritis, lupus, and neurodegenerative diseases.

Registered dietitian Leyla Muedin discusses a Frontiers in Microbiology paper suggesting certain probiotics may help sequester heavy metals. The study, sponsored by the Italian company Probiotical and conducted with University of Ghent and University of Piedmont Orientale, researchers used in vitro testing and the SHIME gut simulator to assess Lactiplantibacillus plantarum, Lactobacillus crispatus, and Lactobacillus acidophilus against cadmium, lead, chromium, and mercury. L. plantarum and L. crispatus reduced metal bioavailability primarily in the simulated colonic phase, while L. acidophilus showed minimal detoxification; mercury was least reduced (~10%). An ex vivo mouse-intestine system found probiotic pre-incubation of metals preserved epithelial integrity and reduced inflammatory responses. Leyla notes limitations: corporate funding, only three strains tested, and no in vivo or human trials, though the findings support further animal and clinical research.

Immune Regulation, Omega-3 Nuance, and Himalayan Tartary Buckwheat with Dr. Austin Perlmutter, chief science officer of Big Bold Health. He details immune regulation as a nuanced, multidimensional system shaped by diet and lifestyle rather than simple “boosting.” Perlmutter explains Big Bold Health’s focus on immunometabolism, educating about immune complexity, and conducting studies on nutraceuticals, including use of CGMs and clinical trials. He discusses why eating fish often outperforms refined fish-oil supplements, noting conventional processing (heat, bleaching, deodorizing, esterification) and loss of other lipids and nutrients. Perlmutter highlights specialized pro-resolving mediators (resolvins, protectins, maresins) and vitamins A and D as potentially better preserved in minimally processed oils, and reviews typical omega-3 intake and target ranges. The conversation also covers immunosenescence/inflammaging and Big Bold Health research on sprouted Himalayan Tartary Buckwheat, its high polyphenols (rutin, quercetin), microbiome effects, and studies including epigenetic aging clocks and brain outcomes.

AI and Generative Biology: Authoring Life, Redesigning Healthcare, and Building Guardrails: Physician and molecular biologist Dr. Adrian Woolfson, co-founder of Genyro, a biotechnology company specializing in synthetic genome design and construction, and author of “On the Future of Species: Authoring Life by Means of Artificial Biological Intelligence,” discusses the convergence of AI with synthetic/generative biology that could make biology programmable and enable genome design and construction beyond traditional gene editing. Woolfson argues that the technology is morally neutral but is arriving rapidly and requires public awareness, governance, and guardrails due to risks, including misuse by authoritarian regimes and biological warfare. He discusses evolution’s trade-offs and why he favors limiting human applications to curing disease and extending healthy longevity, while opposing germline modification; he explains germline vs somatic editing and cites the flawed, unethical case of a Chinese scientist attempting inherited HIV resistance. They examine sickle cell disease cures costing $2–$3 million, scalability issues, and trade-offs like malaria protection, and highlight non-medical benefits such as engineered crops, biomaterials, desalination, and DNA-based information storage.

Bone Health Beyond Calcium: Vitamin D, K, Protein, Medications, and Metabolic Risks: Registered dietitian nutritionist Leyla Muedin discusses factors affecting bone health, osteopenia/osteoporosis, and limitations of bone mineral density as a measure of bone strength. She emphasizes optimizing vitamin D via 25-hydroxy D testing (aiming roughly 55–85 and avoiding over 100), ensuring vitamin K for proper calcium placement, and addressing malabsorption from GI conditions, food intolerances, or inflammation. She notes long-term proton pump inhibitor use can impair calcium and magnesium absorption and increase osteoporosis risk. Diet considerations include avoiding overly grain-heavy, acid-forming patterns and ensuring high biological value protein; she also mentions heavy metals affecting bones. Additional assessment includes magnesium and DHEA sulfate, plus resistance and balance training (ideally three times weekly). She highlights research linking hyperinsulinemia/type 2 diabetes/cardiovascular disease to fragility fractures despite normal or higher bone density, proposing carbohydrate restriction, fasting, and ketosis to improve bone remodeling via osteocalcin and mitochondrial function.
