#625 Why You're Not Burning Fat: Metabolic Testing, VO₂ & FatMax Explained with Daniel Crumback

Are you training hard, eating clean… yet still not seeing fat loss or performance improvements? Today, metabolic testing expert Daniel Crumback joins me to explain how metabolic testing helps you finally stop guessing and start personalizing your training, nutrition, and recovery based on real physiology. We break down exactly what we measure in a Resting Metabolic Rate test and an Active VO₂ Peak test — including fat vs. carb utilization, metabolic flexibility, ventilatory thresholds (VT1 & VT2), FatMax, VO₂ peak vs. max, and heart-rate zones based on your actual data, not formulas. You'll learn how to: • Improve fat burning at rest and during exercise • Identify breathing, cardiac, or metabolic limitations • Train smarter with accurate Zone 2, tempo, and interval zones • Support longevity and mitochondrial health • Adapt training for midlife hormones and stress load Daniel and I also share the most common mistakes people make before and after testing — and how getting your physiology right can transform your results. If you're stuck doing "all the right things" with no payoff, this episode will show you the missing data your body has been trying to tell you.
