"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.

• 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

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber sit down with Dr. Asa Andrew, physician, chiropractor, functional medicine expert, and host of the nation's largest health talk radio show.

Dr. Asa shares his unique journey from professional wrestling to clinical practice—and back again—highlighting how metabolic testing, VO₂ max, and cardiorespiratory fitness have become foundational tools for performance, injury prevention, and long-term health.

From elite athletes and entertainers to everyday patients in their 70s and 80s, this conversation explores why VO₂ max should be treated as a key vital sign, how it predicts longevity more effectively than many traditional metrics, and why most age-related decline is driven by deconditioning—not aging itself.

This episode bridges the gap between healthcare and fitness, showing how actionable metabolic data empowers people to stop guessing, avoid burnout, and take the next right step toward better health—at any age.

• 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 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
