    Ep. 62 - How We Helped a Injured Runner Lose 20 Lbs Without a Weight Loss Program (Real Case Study)

    In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber walk through a real-world case study of a female runner in her 40s one who was stuck in a cycle of injuries, told to stop running, and struggling to lose weight despite years of effort. Using resting metabolic rate (RMR) testing, VO2 max data, and evidence-based exercise prescription, they break down exactly how they designed a program focused on injury prevention and performance, and how weight loss followed naturally as a byproduct. You Will Learn: Why telling injured runners to "rest it away" creates a vicious cycle that destroys tissue capacity over timeHow RMR data revealed this client preserved muscle mass during 12%+ body weight lossWhy metabolic adaptation causes RMR to drop 5–30% beyond what fat loss alone explains and how to track itThe load vs. capacity framework that allowed this client to run every single day for a year injury-freeHow Zone 2 training reduced injury risk while actually improving race paces at age 41Why adherence not the "optimal" program is the single biggest predictor of weight loss successHow protein intake (1.6g/kg) and resistance training protect fat-free mass during weight lossThe danger of false dichotomies in fitness (HIIT vs. Zone 2, cardio vs. strength) and why both are neededWhy bone stress injuries are usually an under-fueling problem, not an overuse problemHow to use metabolic retesting to iterate your coaching when results aren't going as expected

    Ep. 61 - Why Research Alone Can't Save You: Applying Science to YOUR Body (N of 1 Explained)

    Get A Demo: https://korr.com/contact/video-demo/   In this episode of Metabolic Mastery, hosts Dr. Marc Humbert and Dr. Cameron Garber tackle one of the most misunderstood challenges in health and fitness: how to take population-based research and actually apply it to the individual in front of you — the "N of 1." With an overwhelming flood of new studies published daily, it's easy to either over-rely on research or dismiss it entirely. Marc and Cameron walk through a practical framework for reading research critically, understanding study design, and using metabolic testing data — including VO2 max and resting metabolic rate — to personalize care and training in the real world. You Will Learn: What "N of 1" means and why it matters for your health and trainingHow to evaluate research quality, including study design, population relevance, and statistical vs. clinical significanceWhy your VO2 max or RMR result may look "normal" but still be telling an important story about your individual trajectoryThe difference between a research roadmap and a blueprint — and how to stop confusing the twoHow Bayesian reasoning can help you update your beliefs without flip-flopping on every new studyWhy placebo effect, natural disease history, and confirmation bias can fool even experienced cliniciansHow the "evidence-based medicine funnel" works: best available research → clinical expertise → individual goals and constraintsReal examples of how metabolic testing reveals outliers that population averages would completely missWhy effect size matters just as much as statistical significance when evaluating any interventionHow to run your own mini N of 1 experiments over time using repeat metabolic testingFollow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery

    Ep. 60 - What Your Breath Actually Tells Us About Your Body (And Why It Matters)

    Get A Demo: https://korr.com/contact/video-demo/ Have you ever wondered how a device that just measures your breath can tell you how many calories you're burning, what fuel your body is using, and how well your heart, lungs, and muscles are working together? In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down the fascinating science behind indirect calorimetry and the CardioCoach — in plain language anyone can understand and explain. You Will Learn: What metabolism actually is — and why it's so much bigger than just weight loss or fat burning How your body's three energy systems (ATP-PCr, glycolytic, and oxidative) work together at every intensity level Why the Krebs cycle and electron transport chain matter for your fitness — explained simply What the Respiratory Exchange Ratio (RER) is and how it reveals whether you're burning fat or carbohydrates How indirect calorimetry calculates calories burned from just your breath — and the foundational science behind it What VO2, VCO2, and VO2 pulse actually mean and what they tell us about your cardiovascular health Why metabolic testing isn't just for elite athletes — and how it can help anyone exercise smarter and live longer Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery

    Ep. 59 - Fasted Cardio, Cortisol & Fat Burning — What the Science Actually Says

    Get A Demo: https://korr.com/contact/video-demo/   Are you optimizing your workouts based on short-term signals that may not actually lead to long-term results? In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down one of the most misunderstood concepts in fitness — the difference between what happens in your body during a single workout versus what actually drives lasting adaptation over time. You Will Learn: Why fat oxidation during a workout is NOT the same as fat loss over time The real science behind fasted cardio and train-low strategies — and when they help or hurt Why cortisol and insulin get unfairly demonized, and what they actually do in your body How short-term hormonal spikes (testosterone, IGF-1, cortisol) do or don't predict long-term outcomes like muscle growth Why Zone 2 training drives mitochondrial and cardiovascular adaptation — and how metabolic testing helps you stay in the right zone A practical framework for evaluating health and fitness claims you see on social media Why consistency — not any single workout strategy — is the biggest lever for long-term health Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery

    Ep. 58 - Debunking the Metabolism Myth: What's Actually Happening to Your Body After 40

    Get A Demo: https://korr.com/contact/video-demo/   Think your metabolism fell off a cliff the moment you hit your 40s? Think again. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down the real science behind aging and metabolism — and why most of what you've been told is a myth. You Will Learn: Why aging isn't the real culprit behind weight gain, injury, and metabolic slowdown — and what actually is How your stage of life (not your age) creates the "perfect storm" that wrecks your health The truth about wear and tear, and why your old injuries probably aren't the reason you're still hurting Why NEAT (non-exercise activity thermogenesis) may matter more than your workouts How to use Zone 2 training and metabolic testing to exercise in a way that actually builds you up instead of breaking you down Why muscle is the organ of longevity — and exactly what happens when you lose it Simple, sustainable strategies to defy aging and actually improve with time Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery

    Ep. 56 - Why Everything You've Been Told About Cardio Is Wrong (According to Science)

    Get A Demo: https://korr.com/contact/video-demo/ Is cardio bad for your knees? Does running destroy your joints? Will endurance training make you weak? In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber tackle the most common endurance training myths circulating on social media and break down what the science actually says. They explore why cardio gets such a bad rap, how incorrect dosing — not the activity itself — is responsible for most exercise-related injuries, and why the "cardio vs. strength training" debate is a false choice. The doctors also dig into how VO2 max is a powerful proxy for whole-body health, why your heart actually benefits from endurance training, and how individualized metabolic testing can help you finally exercise smarter, not just harder. You Will Learn: Why "overuse injury" is actually a misleading term — and what's really happening How zone training prevents knee pain and accelerates recovery Why VO2 max is one of the greatest predictors of longevity The truth about cortisol, inflammation, and what exercise actually does long-term Why endurance athletes live longer — and what the data says about strength-only athletes How to dose exercise like a prescription to get results without burning out   Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery

    Ep. 55 - The RMR Test Mistakes Everyone Makes (And How Bad Breathing Ruins Your Metabolic Data)

    Get A Demo: https://korr.com/contact/video-demo/ In this episode of Metabolic Mastery, hosts Dr. Marc Humbert and Cameron Garber sit down with Daniel Crumback — KORR's Director of International Sales, certified exercise physiologist, chartered physiotherapist, and certified strength and conditioning coach — for a deep dive into one of the most overlooked data sets in metabolic testing: respiratory values. While most practitioners stop at VO2 max or basic metabolic markers, Daniel reveals how tidal volume, breathing frequency, and lung function norms can expose performance limiters that no one else is talking about. From RMR test quality issues caused by over-breathing, to identifying whether an athlete has a respiratory capacity or capability problem, this episode is packed with clinical insight and real-world testing examples. You Will Learn: Why most RMR tests produce invalid data — and how breathing pattern is usually the culprit What normal tidal volume and respiratory frequency look like at rest and across all training zones How to use the GLI (Global Lung Function Initiative) calculator to establish personalized respiratory norms How to calculate peak tidal volume as a percentage of predicted FEV1 to identify respiratory limitation Why VE (minute ventilation) masks serious breathing problems that individual respiratory values reveal How hyperventilation impairs oxygen delivery, cardiovascular output, core stability, and decision-making The difference between a respiratory capacity limitation vs. a capability limitation — and why the training response is completely different How recovery data after an exercise test reveals critical information about breathing patterns Why you should never remove the mask at the end of a test — and what that post-effort data tells you Practical strategies for improving test quality and helping clients breathe normally during RMR testing  Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery
