    "Calories in, calories out" is a real principle—but it's not a helpful plan unless you understand what drives each side of the equation. In this episode, Dr. Marc Humbert and Dr. Cameron Garber break down the physiology behind energy balance, why scale weight can be wildly misleading, and why people feel stuck even when they're "doing everything right."

    You'll hear how appetite, food processing, stress, sleep, and the modern food environment quietly push calories in—while metabolic adaptation, sedentary lifestyles, and declining NEAT (non-exercise activity thermogenesis) suppress calories out. Then, the conversation shifts to what actually works long-term: building sustainable systems, using exercise to "tune up the machine," and focusing on body composition and metabolic health instead of daily scale fluctuations.

    What you will learn
    • Why calories in vs. calories out is true—and why it still feels like it "doesn't work" in real life

    • The difference between scale weight vs. fat mass, and why day-to-day weigh-ins can create false conclusions

    • How macronutrient shifts, sodium, digestion, and water retention can swing the scale fast without changing body fat

    • The biggest drivers of "calories in": energy density, hyper-palatability, labels/portion variability, absorption, stress, and sleep

    • Why NEAT is often the hidden lever for fat loss (and why "just exercise more" is rarely the answer)

    • What metabolic adaptation is, why plateaus happen, and how RMR testing can guide smarter adjustments

    • How VO₂ testing and heart-rate zones change over time—and why retesting improves results

    • The real relationship between hormones/menopause/aging and body composition (including fat distribution changes)

    • Why fitness can outweigh BMI for health risk—and why "losing weight fast" can backfire metabolically

    • A practical framework to reduce shame: skill gap vs. will gap vs. environment gap

    What You'll Learn in This Episode
    • Why VO₂ max is one of the strongest predictors of longevity and all-cause mortality

    • How metabolic testing improves safety and performance in high-demand sports like professional wrestling

    • The difference between weight loss and healthy weight loss that preserves lean mass

    • Why many signs of "aging" are actually the result of inactivity and lost capacity

    • How VO₂ max and RMR testing guide personalized training and nutrition decisions

    • Why fitness and healthcare must converge to support long-term health outcomes

    • How actionable data helps patients avoid pseudoscience and fitness fads

    • Why it's never too late—or too early—to improve cardiorespiratory fitness

    Biomarkers are everywhere in health, fitness, and wearable technology—but more data doesn't always mean better insight. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down what biomarkers actually are, why not all biomarkers are created equal, and how misleading metrics can obscure meaningful health decisions.

    The conversation cuts through buzzwords like "cellular fitness," "biological age," and proprietary health scores to explain the difference between measured, calculated, and extrapolated biomarkers. You'll learn why standardized testing conditions matter, how poor data can lead to decision paralysis, and why the best biomarkers don't give answers—they help you ask better questions.

    If you've ever wondered whether your health data is actionable or just decoration, this episode provides a clear framework for evaluating biomarkers and using them responsibly to improve real-world health outcomes.

    What You'll Learn
    • What a biomarker actually is—and why definitions matter

    • The three tiers of biomarkers: measured, calculated, and extrapolated

    • Why more biomarkers do not automatically mean better insight

    • How marketing-driven health scores can mislead patients and clinicians

    • Why VO₂ max is a powerful biomarker—and where its limits are

    • The importance of standardized testing conditions for repeatable results

    • How wearables can create anxiety and decision paralysis when misused

    • Why biomarkers should reduce uncertainty, not add noise

    • How good data leads to better questions—not instant answers

    • A practical framework for deciding which biomarkers are truly useful

    Dec 30 2025

    Get A Demo: https://korr.com/contact/video-demo/

    In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down why metabolic testing is one of the most powerful tools for improving health, fitness, and longevity—regardless of your current fitness level.

    From beginners restarting after years away from exercise to advanced athletes stuck in cycles of injury or plateau, this conversation explains why relying on generic programs, social media workouts, or willpower alone often leads to burnout, frustration, and inconsistent results.

    The doctors explain why VO2 max, while valuable, tells only part of the story—and how comprehensive metabolic testing reveals how your muscles, heart, lungs, and metabolism actually work together. With the right baseline data, fitness becomes personalized, measurable, and sustainable.

    If you're tired of guessing, restarting every January, or following plans that don't fit your body or lifestyle, this episode shows how better data leads to better decisions—and better outcomes.

    What You Will Learn
    • Why motivation alone isn't enough to achieve long-term fitness success

    • Why VO2 max is important—but not the full picture of health or performance

    • How metabolic testing creates a personalized fitness and longevity roadmap

    • Why beginners, intermediates, and elite athletes all benefit from testing

    • How improper training leads to burnout, injury, and plateaus

    • Why consistency—not intensity—wins in the long run

    • How metabolic data helps match training effort to real physiological goals

    • Why metabolic testing is a baseline you can't "fail"

    • How testing supports fat loss without sacrificing muscle or metabolic health

    • Why starting with data prevents the cycle of stop-and-start fitness

  • Ep. 34 - Heart Rate Recovery, METs, and Efficiency: The Metrics That Predict Performance
    Dec 23 2025

    Get A Demo: https://korr.com/contact/video-demo/

    In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber are joined by Daniel Crumback (Director of International Sales at Core Medical Technologies, and Director of Strategic Health & Performance) to break down how physiological testing can uncover the real reason someone stalls in fitness, performance, and health.

    Most people think VO2 max and RMR testing ends with a score and a set of training zones. Daniel makes the case that's just the surface. By analyzing oxygen and carbon dioxide data (not O2 alone), you can differentiate whether a person is primarily limited by cardiovascular capacity, respiratory mechanics, metabolic flexibility, neuromuscular function, or efficiency—and then build training and nutrition prescriptions around the true limiter instead of guessing.

    The team also walks through practical interpretations: heart rate recovery, VO2 peak vs VO2 max, tidal volume vs breathing frequency, fat/carbohydrate crossover, peak fat oxidation, and "efficiency" markers like VO2 per breath and VO2 pulse. They emphasize why protocol design matters, how bad assumptions (like mis-set warmups or mislabeled "fat max") lead to wrong prescriptions, and why retesting every 8–12 weeks is the difference between "working out" and actually improving physiology.

    What you will learn
    • How to identify whether a person's primary limiter is cardio, respiratory, metabolic, neuromuscular, or efficiency

    • The difference between VO2 peak vs VO2 max, and why it matters for prescribing training

    • Why O2 + CO2 measurement unlocks a deeper analysis (fat oxidation, crossover, metabolic flexibility)

    • How to interpret heart rate recovery and what it can indicate about stress and cardiovascular fitness

    • What tidal volume vs breathing frequency can reveal about respiratory limitations and hyper/hypoventilation

    • How to use fat/carbohydrate crossover and peak fat oxidation to spot metabolic dysfunction (and training mistakes)

    • Why "zone 2" prescriptions often fail without correct protocol setup and correct interpretation

    • How METs relate to real-world function and why very low METs can signal broader limitations

    • Two powerful efficiency lenses: VO2 pulse (oxygen per heartbeat) and VO2 per breath (oxygen per breath)

    • A practical retesting cadence: why 8–12 weeks after consistent implementation is the sweet spot

    In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber walk through a real-world consultation involving a collegiate runner whose metabolic test results didn't match expectations. What starts as a simple test review turns into a deep exploration of training errors, load vs. capacity, the dangers of chronic overload, and how individualized training can transform performance and longevity.

    Cameron and Marc break down why athletes—especially collegiate endurance athletes—often fall into cycles of injury, overtraining, and frustration. They discuss how heart rate–based training, metabolic testing, fueling strategies, and better lifestyle assessment can uncover the true causes of plateaued performance. You'll learn how elite runners train (hint: much slower than you think), why most people spend too much time in Zone 3, and what it takes to build a resilient, high-performing athlete.

    This episode is a masterclass in how to ask the right questions, interpret metabolic data, and design training that keeps athletes in the game rather than sidelined by injury.

    WHAT YOU WILL LEARN
    • How to interpret metabolic test results in the context of an athlete's training history

    • Why most performance problems are training errors, not equipment errors

    • The difference between overload vs. overuse, and why it matters for injury prevention

    • How chronic life stress, poor sleep, and inadequate fueling disrupt performance

    • Why Zone 2 training is foundational—and why Zone 3 can be the "no-progress zone"

    • How elite athletes use slow training to build world-class performance

    • The importance of heart rate auto-regulation for day-to-day training decisions

    • How metabolic testing improves fueling strategies, resilience, and recovery

    Dec 9 2025
    Get the book: https://shopenrgperformance.com/hard-copy-books-1 https://shopenrgperformance.com/ebooks And Learn More About Bob: Website: https://www.enrgperformance.com/metabolic-efficiency-training YouTube: https://www.youtube.com/@Enrgperformance In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber sit down with Bob Seebohar – registered dietitian, exercise physiologist, founder of the Metabolic Efficiency Training™ concept and Energy Performance, and author of Metabolic Efficiency Training (3rd Edition). Bob shares how failing his first sprint triathlon as a "land athlete" soccer player became the catalyst for a career spent in the trenches with athletes. He walks through the origins of nutrition periodization, the birth of metabolic efficiency testing, and why traditional "just eat more carbs" advice often leads to GI distress, underperformance, and confusion—especially for recreational athletes. You'll hear how metabolic carts, substrate oxidation data, and smart training can transform an athlete from a carb-dependent "sugar burner" into a fat-burning, metabolically efficient machine, all while improving health, longevity, and performance. What You'll Learn Bob's unique path from exercise physiologist to registered dietitian and how that dual background shaped Metabolic Efficiency Training. Why energy systems matter (aerobic vs anaerobic) and how misunderstanding them wrecked Bob's first triathlon—and shaped his entire career. The origin of nutrition periodization and why athletes should eat to train, not train to eat. How GI distress in endurance sports led Bob to develop metabolic efficiency testing and rethink high-carb race fueling. What metabolic efficiency testing actually measures: Fat vs carbohydrate oxidation The metabolic efficiency (crossover) point Calories burned per hour How to turn that data into precise fueling plans Why so many recreational runners and triathletes show up as "pure carb burners" on the metabolic cart—and what to do about it. The difference between elite fueling strategies and what's realistic (and safe) for everyday athletes. How optimizing blood sugar and fat oxidation improves performance and long-term health and longevity. Why Zone 2 training is so uncomfortable mentally, and how heart rate monitors should mostly be used to hold you back, not push you harder. How metabolic efficiency testing can guide calorie and carbohydrate intake per hour instead of guessing from generic "30–90g carbs per hour" charts. The role of metabolic flexibility and how to train your body to use the right fuel at the right time. The power of N=1 experiments and why self-testing (with good equipment) is one of the fastest ways to gain coaching wisdom. Why Bob advocates simple, qualitative nutrition models instead of obsessive calorie and macro counting for most people. The difference between biological hunger, habitual hunger, and emotional hunger, and how each one affects performance and body composition. How often you should feel hungry if your blood sugar and fat oxidation are dialed in. Why Bob waited 10 years to release the 3rd edition of Metabolic Efficiency Training and what's new in it (masters athletes, updated strategies, case studies).
