What are Macros in Nutrition and Health

If you have just started to explore the concept of proper nutrition and fitness, chances are that you have encountered the word ‘macros’ or macronutrients. Macronutrients, also known as macronutrients, are a key part of nourishing your body with essential nutrients. Macros in nutrition are nutrients that give your body energy, known as calories. This energy is created when macronutrients are broken down during the process of digestion. To understand what macros in nutrition are and their role in human health, it is important to understand the three types of macronutrients and the number of calories each provide.

The Three Types of Macronutrients

The three types of macronutrients in nutrition and health are: proteins, carbohydrates, and fats. Each of these macronutrients provides a specific amount of energy or calories per gram of food.

  • Proteins: 4 calories per gram, or 4 Kcal/g
  • Carbohydrates: 4 calories per gram, or 4 Kcal/g
  • Fats: 9 calories per gram, or 9 Kcal/g

What are the benefits of Macronutrients?

It is important to understand the role of each macronutrient in nutrition and health and how they can provide essential nutrients to your body.

  • Proteins: Proteins provide your body with essential amino acids that help to build and maintain muscle, bones, and organs. It is also necessary for wound healing, hormone function, and metabolic regulation.
  • Carbohydrates: Carbohydrates provide energy for your body to use for physical activity, brain function, and overall growth.
  • Fats: Fats provide your body with essential fatty acids that help with absorption of fat-soluble vitamins, cell membrane maintenance, hormone production, and energy storage.

    By consuming a balanced diet that includes all macro-nutrients, you can ensure your body is receiving all of the necessary nutrients it needs to be healthy.

    How to Calculate Your Macronutrient Intake

    To determine the amount of macronutrients you need for optimal health, you will need to calculate your daily caloric needs and divide that number by the number of calories each macro-nutrient provides. Most experts recommend a balance of 25-30% protein, 45-65% carbohydrates, and 20-30% fat.

    Once these goals have been reached, you can begin to adjust your macros according to your health goals. For example, if your goal is to lose fat, you would need to decrease your carbohydrate intake and increase your protein and fat intake.


    Whether you are looking to lose weight, gain muscle, or maintain your current weight, understanding how macros in nutrition and health work together is essential for achieving your health goals. By consuming a balanced diet, including all three macro-nutrients, you can ensure your body is receiving all of the essential nutrients it needs to function optimally. With proper education, creating a personalized nutrition plan that works for you can be easier than ever.
