Your Metabolism Explained

What's really happening when you "can't lose weight"

Metabolism is not a mystery — it's a measurable set of physiological processes. Your basal metabolic rate, non-exercise activity thermogenesis, thermic effect of food, and exercise energy expenditure all combine to determine how many calories your body burns each day.

Understanding these components gives you real leverage. You can't change your genetics, but you can meaningfully influence your metabolic rate — particularly through muscle mass, which is the single biggest driver of resting metabolism.

This course demystifies the system, addresses the most common myths, and gives you a clear, evidence-based framework for managing your energy balance without restriction or guesswork.
