 What are macronutrients?

Macronutrients are nutrients that your body needs in large amounts to function optimally.

The three main macronutrients are carbohydrates, protein, and fat. They’re considered essential nutrients, meaning your body either cannot make them or cannot make enough of them.Trusted Source

For example, proteins provide essential amino acids, while fats contain essential fatty acids. Your body utilizes these components for specific functions.Trusted Source

Macronutrients also contain energy in the form of calories. Carbs are the main energy source, but your body can use other macronutrients for energy if needed.Trusted Source

The calorie content of each macronutrient is:

  • Carbs: 4 calories per gram
  • Protein: 4 calories per gram
  • Fat: 9 calories per gram
