Understanding the Basics: Nutrition, Metabolism, and Energy Balance

Nutrition isn’t just about eating; it’s about providing your body with the essential building blocks it needs to function, grow, and repair itself. These building blocks come in the form of macronutrients and micronutrients, each playing a critical role in your overall health.
