In this episode of The Feldman Protocol, Greg Mushen, a longtime technology and product leader turned independent health researcher, makes the case that disciplined thinking from Silicon Valley can meaningfully inform nutrition and metabolic health. The discussion also directly engages with debates raised by the Keto-CTA study, using it as a case example to examine data transparency, scientific criticism, and decision-making under uncertainty—alongside metabolic testing innovation, walking versus high-intensity exercise, protein prioritization, and Greg’s own body recomposition—through a skeptical, analytical lens.

In this episode of The Feldman Protocol, a core question hangs over the conversation: how did so many clinicians and patients miss low-carb interventions for so long? Dave sits down with Doug Reynolds, founder of Low Carb USA and president of the Society of Metabolic Health Practitioners, as the guest makes the case for carbohydrate reduction in chronic disease, practitioner education gaps, cultural food traditions, patient-driven change, conference-based knowledge sharing, and why engineers often follow data over authority.

In this episode of The Feldman Protocol, a provocative question anchors the conversation: how much of cardiovascular risk is about cholesterol itself versus the context it operates in? Guest **Josh Wageman, DPT, PA-C, PhD**—a clinical lipid specialist and researcher—makes the case for using metaphor, metabolic health, and imaging to think differently about risk. The discussion spans coronary calcium scoring, lipid particles, insulin and inflammation, endurance training extremes, neurodegeneration, and why communicating science clearly actually matters. 🔥 This episode is sponsored by us -- Own Your Labs `http://ownyourlabs.com` -- private blood testing services.🩸Over 300 blood tests💰Extremely affordable❤️ We love our customers(Yes, we are literally funding the entire podcast from our own company -- so if you want to show your support, keep getting your private blood testing through our service.

In this episode of The Feldman Protocol, Dave asks: what happens when a fertility specialist-turned-health thinker questions nutrition narrative? Guest Robert Kiltz, MD, makes the case for animal-based diets, metabolic flexibility, mindset, faith and medicine, clinical experience vs. guidelines, and the role of community. The conversation ranges from physiology and lipid metabolism to entrepreneurship, skepticism, and personal practice — always with an eye toward evidence and open inquiry.

In this episode of The Feldman Protocol, Dave asks a blunt question: is modern medicine structurally aligned against prevention? Guest **Emily Kaplan**, investigative science journalist and co-founder of the Broken Science Initiative, makes the case that incentives, not evidence, increasingly shape medical practice. They discuss conflicts of interest in research, the reproducibility crisis, metabolic health and lifestyle medicine, GLP-1 drugs, nutrition education gaps, and why outcomes often matter less than headlines.🔥 This episode is sponsored by us -- Own Your Labs `http://ownyourlabs.com` -- private blood testing services.🩸Over 300 blood tests💰Extremely affordable❤️ We love our customers(Yes, we are literally funding the entire podcast from our own company -- so if you want to show your support, keep getting your private blood testing through our service.

In this episode of The Feldman Protocol, a central question hangs over the conversation: what actually causes a heart attack when standard risk markers look “normal”? Guest Dr. Stephen Hussey, DC (functional medicine practitioner focused on cardiovascular disease), makes the case for re-examining core assumptions about heart disease. Topics include plaque vs. risk, LDL cholesterol, CAC scoring, stress physiology, hydration, type 1 diabetes, endurance exercise, and alternative mechanisms behind myocardial infarction.

In this episode of The Feldman Protocol, we ask: What happens when clinical guidelines collides with messy real-world outcomes? Guest Bret Scher, MD, makes the case for rethinking metabolic health, evidence hierarchies, clinical incentives, LDL interpretation, ketogenic therapies, guideline rigidity, psychiatric applications of metabolic interventions, and his own evolution from cardiologist to medical director in the metabolic-health space.🔥 This episode is sponsored by us -- Own Your Labs http://ownyourlabs.com -- private blood testing services.🩸Over 300 blood tests💰Extremely affordable❤️ We love our customers(Yes, we are literally funding the entire podcast from our own company -- so if you want to show your support, keep getting your private blood testing through our service.

In this episode of The Feldman Protocol, what if a single overlooked nutrient could meaningfully alter how we think about chronic illness? Guest Dr. Darren Schmidt (DC, nutrition-focused clinician) makes the case for the role of B1 deficiency, discusses environmental toxic exposures, explores mitochondrial dysfunction, and examines lactic acidosis as a framework for understanding complex disease patterns. We also discuss metabolic pathways, autonomic issues, and how clinical observations can challenge conventional assumptions.
