#220 Wnt vs DHT: Understanding Androgenic Alopecia and the Top Treatments to Slow Hair Loss

In this solo episode on androgenic alopecia, the host explains that hair loss is slow and progressive, driven largely by genetics and DHT-mediated miniaturization of follicles across the anagen, catagen, and telogen cycle, and stresses early detection using periodic photos of the temples, hairline/vertex, and crown. He frames hair growth as a "battle" between Wnt signaling (promotes growth and anagen entry via stem cell activation) and DHT signaling (suppresses Wnt and increases inhibitors like DKK, TGF-beta, and PGD2), noting advanced loss involves inflammation, fibrosis, and irreversible follicle loss. He reviews contributors like poor scalp blood flow, iron deficiency (most evidence), possible zinc/B12/folate deficiency, thyroid dysfunction, and insulin resistance, then covers treatments: finasteride (oral and topical) and dutasteride as DHT blockers with potential systemic side effects, plus minoxidil and microneedling (home vs professional) as key options, with add-ons like ketoconazole shampoo, PRP, red light, and cautions about anabolic steroids and high-dose testosterone increasing DHT pressure.

#219 Dr. Allen Frances on AI Chatbots, Mental Health Risks, Privacy, and the Overdiagnosis of Autism

Dr. Allen Frances discusses how AI chatbots can provide effective support for everyday stress and mild symptoms, with tens of millions using them, but warns they can be dangerous for vulnerable groups—especially the very young, the very old, the socially isolated, and people with severe mental illness—potentially contributing to psychosis, suicide, or eating disorders. He argues harm is driven by chatbots being programmed to be pleasing and validating to maximize screen time, creating dependency and "echo chambers," and highlights major privacy risks and manipulation potential given extensive data collection and weak safeguards. Frances advocates a hybrid model where therapists and patients train chatbots as assistants aligned with treatment goals, and cautions about industry profit motives, limited regulation, scams, political propaganda, and broader societal risks. He also explains autism's overdiagnosis since DSM-IV's expansion (Asperger's/autism spectrum) and describes ADHD and autism as current fad diagnoses amplified by services and social media. Dr. Allen Frances is a psychiatrist, author, and leading voice on psychiatric diagnosis, mental health, and the risks of overmedicalization. He is widely known for his work on the DSM-IV and for his book Saving Normal, which challenges the overdiagnosis and overtreatment of everyday life struggles. In this episode, he joins Dr. Mike Hart to break down the growing impact of AI chatbots on mental health, therapy, privacy, and clinical care. He explains when chatbot support may be helpful, why vulnerable users can be harmed, how AI could reshape psychotherapy, and why privacy with chatbots may be an illusion. He also discusses the overdiagnosis of autism and ADHD, the role of social media in self-diagnosis, and why false labels can change how people see themselves and their future.

#218 Lab-Grown Meat, Grocery Prices, and the Real Drivers of Food Inflation in Canada (with the Food Professor)

In a wide-ranging interview, Dr. Sylvain Charlebois ("The Food Professor") discusses whether lab-grown (cellular) meat is overhyped, citing consumer acceptance, cost, and labeling as key barriers, though he found lab-grown chicken indistinguishable in taste and notes potential for nutrient customization. The conversation then turns to Canadian food inflation, arguing there is little evidence grocers are gouging consumers via higher margins, though grocers pressure suppliers through fees, affecting prices and supply-chain discipline. Charlebois contends food inflation is largely structural and policy-driven, pointing to trade barriers, carbon tax impacts, logistics, supply management, counter-tariffs, and the GST holiday's inflationary effect. He proposes solutions focused on competition, tax relief, logistics investment, and policy reform, and closes with a cautious view of ultra-processed food rhetoric, emphasizing consumer information over bans. Dr. Sylvain Charlebois is a professor of food distribution and policy at Dalhousie University and director of the Agri-Food Analytics Lab, where his work focuses on food distribution, food policy, food security, and food safety. Widely known as "The Food Professor," he is one of Canada's most recognized voices on food inflation, grocery pricing, supply chains, and the future of food. His research has been featured in major outlets including The Economist, The New York Times, The Wall Street Journal, and The Globe and Mail, and he also hosts The Food Professor Podcast. In this episode, he breaks down what's really driving food prices in Canada, whether grocers are being unfairly blamed, the debate around lab-grown meat, and how ultra-processed foods and GLP-1 drugs are reshaping the food industry.

#216 VO2 Max, Zone 2 Training, HRV Wearables, Sauna, and Evidence-Based Performance Supplements with Brady Holmer

Dr. Mike Hart interviews elite runner Brady Holmer about endurance training, VO2 max physiology, and common misconceptions. Holmer explains that zone 2 builds the aerobic base and enables high training volume with less fatigue, notes heart-rate zones are ideally defined by lactate thresholds, and says he primarily uses perceived exertion rather than lactate or heart rate during training. He advises against guiding workouts by wearable HRV scores, arguing accurate HRV requires standardized morning measurements and that wearable data can create a nocebo effect; trends may be informative, but subjective feel should come first. They discuss polarized vs pyramidal training and typical 80/20 intensity distributions, effective session durations, mechanisms limiting VO2 max (central vs peripheral), and why Norwegian 4x4 intervals work by maximizing time near 85–90% max heart rate. They cover breathing/nose breathing, inspiratory muscle training, sauna/hot baths as performance adjuncts, nutrition timing of carbohydrates, and supplements including beetroot, beta-alanine, urolithin A, and post-exercise ketones. Brady Holmer is an endurance-focused performance expert and elite runner whose work explores the science and practice of aerobic fitness, VO2 max, recovery, and smarter cardio training. In this episode, he explains how zone 2 training builds the foundation for endurance, why HRV and wearable data should be interpreted carefully, and how protocols like Norwegian 4x4 can improve performance when used in the right context. Through a blend of long-term training experience, research literacy, and practical coaching insight, Holmer helps listeners better understand how to train harder, recover smarter, and think more clearly about what actually improves cardiovascular fitness.

#215 Brain Health From Morning to Night: Sleep, Exercise, Supplements, Screens, and ADHD Meds

Dr. Tommy Wood discusses evidence that stimulants can help people with ADHD but may worsen complex cognitive performance in non-ADHD users despite feeling more focused. He outlines an ideal brain-health day centered on consistent sleep opportunity, morning caffeine timed to protect sleep, nutrient-dense meals (protein, B vitamins, omega-3s, fiber, antioxidants), frequent movement to break up sedentary time, and structured exercise including cardio, resistance training, HIIT (notably Norwegian 4x4), and open-skill sports for added cognitive benefits. He emphasizes bright morning light and darkness at night for circadian strength, notes optic-flow/nature exposure as helpful but not required, and says electrolytes/salt needs are individual. The conversation covers cognitive decline and bioenergetics/mitochondria, critiques "type 3 diabetes" as oversimplified, reviews mixed evidence for ketones, and addresses supplements (omega-3s, vitamin D, saffron, creatine, polyphenols). Screens can help or harm depending on use and what they displace. Wood promotes his book, "The Stimulated Mind," out March 24. Dr. Tommy Wood is a physician-scientist and brain health expert who helps people better understand how to improve cognition, protect memory, and reduce long-term dementia risk. With a focus on exercise, sleep, nutrition, and brain energetics, he explores the practical habits that support focus, processing speed, recovery, and healthy cognitive aging. Dr. Wood is known for translating complex neuroscience into clear, actionable advice, while challenging oversimplified ideas around stimulants, supplements, and modern brain optimization. Through his research, speaking, and new book The Stimulated Mind, Dr. Wood teaches people how to create the right conditions for better brain function across the lifespan. His work empowers listeners to think of brain health as something trainable—shaped by movement, sleep, learning, and the quality of the inputs we give our minds every day.

#214 Optimal Nutrition: Fiber's Impact on Glucose and Cholesterol

The script explains why fiber is critical for gut and metabolic health, focusing on how soluble fiber is fermented in the colon to produce short-chain fatty acids (butyrate, propionate, acetate). It contrasts soluble fiber (forms a gel, lowers LDL by binding bile acids, slows glucose absorption, increases satiety, feeds the microbiome) with insoluble fiber (adds stool bulk, helps constipation). It highlights research showing 10 g/day psyllium husk (Metamucil) is linked to a 10% reduction in all-cause mortality and typically lowers LDL about 7–15%. Butyrate is emphasized as the primary fuel for colonocytes, supporting gut barrier integrity and potentially reducing colon cancer risk, while also affecting mitochondria, inflammation, and the brain. Propionate influences liver cholesterol production and satiety hormones, and acetate provides systemic energy. Practical supplementation "stacks," dosing ranges, food sources, GI side effects, and timing cautions (e.g., separating psyllium from minerals) are discussed.

#213 Emotions, Mind Control, and Mental Health Labels: A Conversation with Dr. Roger McFillin

Dr. Roger McFillin argues that Western allopathic medicine and psychiatry have medicalized normal human suffering by reducing emotions to biological or chemical reactions, turning symptom checklists into fixed identities, and sustaining a drug-driven "sick care" system that creates lifelong customers. He contrasts this with viewing emotions as powerful energy meant to be moved into creation and transformation, cites psychoneuroimmunology, and warns that suppressing fear and distress with pharmaceuticals can worsen long-term outcomes. The conversation covers exposure-based approaches to unlearn fear, the role of media, social media, and advertising in provoking fear and keeping people in an unconscious "drift" state, and the importance of intentional stillness, solitude (distinct from loneliness), prayer or silent meditation, and reducing phone use—especially at the start of the day—to become more conscious and intentional. McFillin discusses how diagnostic labels like depression and anxiety shape identity, limit choices, and contribute to chronicity and polypharmacy. He contrasts PTSD with post-traumatic growth, emphasizing processing trauma memories, facing avoided situations, challenging overgeneralized threat beliefs, and practicing forgiveness and self-compassion while also taking ownership where appropriate. They also discuss the perceived harms of the "toxic masculinity" concept, men's wellbeing, the loss of wise elders, and how men often bond and cope through shared activities. Dr. Roger McFillin is a clinical psychologist and trauma recovery expert who challenges the medicalization of normal human emotions. With a focus on emotional resilience and personal growth, he specializes in exposure therapy and psychoneuroimmunology, exploring the connection between mind, emotions, and immune health. Dr. McFillin advocates for self-regulation and transforming emotional energy into healing, critiquing the overuse of pharmaceuticals in modern mental health treatment. Through his Substack, Radically Genuine, and podcast, Dr. McFillin educates individuals on overcoming fear, achieving stillness, and reconnecting with their true selves. His work empowers people to shift from a victim mindset to one of active growth, using trauma as a catalyst for resilience and positive change.

#212 Cialis as a Potential Longevity Drug: Vascular, Heart, Metabolic, and Brain Benefits

This episode explores tadalafil (Cialis) as a potential longevity drug, though no randomized human trials prove it extends lifespan. Cialis works by blocking PDE5, enhancing nitric oxide signaling, and improving blood flow through vasodilation. Originally approved for pulmonary hypertension, it's also used for erectile dysfunction and BPH. Its 36-hour half-life makes it superior to Viagra for continuous longevity effects. The host frames vascular aging and endothelial dysfunction as key drivers of age-related diseases (heart disease, stroke, dementia, kidney disease). Observational data shows Cialis users have 44% lower mortality, fewer cardiovascular events, reduced dementia risk, and lower mortality in diabetics. Additional benefits include improved cardiac function, reduced infarct size, arrhythmia suppression, and regression of left ventricular hypertrophy. A 2024 meta-analysis found it lowers hemoglobin A1C, possibly via improved microvascular perfusion, insulin sensitivity, and mitochondrial function. Cialis crosses the blood-brain barrier and may improve neurovascular coupling and hippocampal plasticity, potentially benefiting those with or at risk of dementia. Safety is generally good with long-term daily use (2.5–5 mg), though cautions include avoiding use with nitrates, low blood pressure, or certain retinal disorders. Common side effects are headache, nasal congestion, and acid reflux. The host recommends consulting a doctor and references potential synergy with telmisartan.

#211 Understanding the Anti-Aging Benefits of Telmisartan

In this podcast episode, an in-depth discussion is provided on the drug Telmisartan, commonly used for lowering blood pressure. The host elaborates on how it belongs to a class of medications known as angiotensin receptor blockers (ARBs) and stands out due to its 24-hour half-life and partial PPAR-gamma agonist activity. The episode explores Telmisartan's potential benefits for longevity, including its properties that reduce cardiovascular mortality, renal decline, and metabolic issues. It also compares Telmisartan with other ARBs and addresses its unique ability to improve myocardial efficiency, reduce arterial stiffness, and support neuroprotection. Detailed explanations are given on technical concepts such as pulse pressure and its relevance to arterial compliance, and the necessity to consult a doctor before taking the medication is emphasized.
