The Basics of Macronutrients: Protein, Carbs and Fat Explained

A no-nonsense breakdown of what macronutrients actually do in your body.

By Daved Bennett 1 min read

Nutrition advice often skips the basics. Here’s a quick primer on the three macronutrients and the role each one plays.

Protein

Supports muscle repair and immune function. Most adults benefit from including a source at each meal.

Carbohydrates

Your body’s primary energy source. Quality matters more than avoidance — whole grains and vegetables digest differently than refined sugar.

Fat

Essential for hormone production and nutrient absorption. Unsaturated sources like nuts, olive oil and fish are generally favored over saturated fats.

Balance across all three, rather than eliminating any one, tends to be the more sustainable approach.
