Ep. 5 - Fast vs. Slow Metabolisms—What Really Matters?

Metabolic Mastery

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down one of the most common health questions: Do I have a fast or slow metabolism? They debunk popular myths, explain what metabolism truly is, and why it matters far beyond just weight. You’ll learn about resting metabolic rate, the role of lifestyle and age, and how metabolic testing can transform the way we approach nutrition, exercise, and long-term health.

Whether you're a clinician, gym owner, or simply trying to optimize your energy and longevity, this episode is packed with practical insights into how your body burns energy, adapts over time, and how you can align your goals with science—not guesswork. Discover how measuring metabolism helps shift the conversation from blame to empowerment—and why the best long-term health strategy is to architect a life full of meaningful movement.
