In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber dive deep into the world of wearables—exploring where your fitness tracker shines and where it can seriously mislead you. From heart rate accuracy to calorie burn estimates and VO₂ max predictions, they break down the crucial difference between measured values and calculated estimates.

Listeners will learn:

• Why heart rate chest straps are more reliable than wrist-based sensors.

• How calorie burn estimates can be off by 20–30% (and why that matters).

• The real role of VO₂ testing and why lab-based measurements are still the gold standard.

• How to use wearable data for trends without mistaking it for clinical accuracy.

• Why quality devices and regular metabolic testing are essential for athletes, trainers, and anyone serious about health.

Packed with science-backed insights, practical advice, and real-world examples, this episode helps you cut through the noise of flashy metrics and focus on what truly drives performance, fat loss, and recovery.
