3 Types of Macronutrient and Their Benefits

Counting macronutrients (macros) is a popular method for those who want to lose weight or develop muscle mass. It can help you achieve a variety of health goals. Because macro implies enormous, your body need more of these nutrients to operate effectively. Furthermore, all of these nutrients supply energy to your body in the form of calories or kcals.

Carbohydrates, proteins, and fats are the three categories of macronutrients.

  • Carbohydrates have a caloric value of 4 per gram.
  • Proteins have a caloric content of 4 kcal per gram.
  • Fats provide 9 calories per gram (this is roughly double the amount found in the other two macros)

Along with energy, all of these macronutrients have specific roles in your body that allows you to function properly. 


Macronutrient Carb

All carbs are turned down into glucose, which is your body’s primary source of energy. In reality, several organs, including your brain, require glucose to operate correctly. Gluconeogenesis is the process by which your body produces glucose from proteins when it is required.

Fiber is a form of carbohydrate that your GI tract cannot break down. As a result, though this vitamin does not provide energy, it does assist in the elimination of waste and the maintenance of a healthy digestive tract. Carbohydrates do not all have the same properties. Some carbohydrates are simple, whereas others are complicated.


Simple Carbohydrate

The “simple” term is meant easy for your body to breakdown for energy or glucose. They are present in foods that are typically sweet, such as honey, table sugar, syrup, agave nectar, molasses, milk/yogurt, and fruit, and include 1-2 sugar molecules.

Complex Carbohydrate

It is the opposite of simple carb, complex carb take more time for your body to breakdown. They’re made up of lengthy strands of sugar molecules that have been strung together and have a savory flavor. Starches and grains, such as rice, pasta, bread, and starchy vegetables, contain them (potatoes, peas, corn). Carbohydrates can also be found in non-starchy vegetables (beans, nuts, and seeds), albeit in smaller proportions.


Macronutrient Protein

Protein helps your body develop, mend, and maintain lean body mass by allowing it to develop, develop, and repair tissues (your muscle mass). Amino acids are the building blocks of protein. Protein is made up of amino acids, which are the building blocks of the molecule. There are 2 types of amino acids:

Non-Essential Protein

Non-essential amino acids do not need to be ingested in the diet because your body can produce them.


Essential Protein

Dietary sources of essential amino acids are necessary. Essential amino acids can be consumed on their own or converted into non-essential amino acids in specific instances.

Meat, poultry, fish, eggs, milk, and other animal by-product foods are all high in protein. All of your necessary amino acids are present in these protein sources.

This does not imply that you must consume animal products in order to be healthy. Amino acids may be found in a range of plant protein sources, including beans, nuts, and soy, as well as in smaller levels in grains, vegetables, and fruits.


Macronutrient Fat

Fat aids in the storage of energy, the cushioning of organs, the production of certain hormones, the absorption of fat-soluble vitamins, and the integrity of cell membranes. Fat is divided into three categories:

Saturated Fat

Because it is saturated in hydrogen molecules, there are no bends in the molecule generated by double bonds. Saturated fat has been shown to raise cholesterol levels and increase the risk of heart disease when consumed in significant amounts. It may be advantageous to reduce the quantity of saturated fat in your diet.

Saturated fat is found mostly in animal sources with high fat contents such as fatty beef, lamb, pork, poultry with skin, lard, cream, butter, full fat cheese, and dairy.


Unsaturated Fat

It has at least one double bond that causes the molecule to bend. Because they are more difficult to stack, they are frequently found in a liquid condition at ambient temperature. The amount of double bonds allows unsaturated fats to be named. Poly unsaturated fats have numerous or many double bonds, whereas mono unsaturated fats contain only one. Unsaturated fats are referred to be “good fats” since they lower the risk of heart disease.

Avocados, nuts and nut butters, seeds, olives, and oils are all good sources of these beneficial fats (olive, canola, safflower etc.). Animal sources include fatty fish such as salmon, mackerel, sardines, tuna, and herring, among others.

Trans Fat

It should be eliminated from the diet. Hydrogenation, or the addition of hydrogen molecules to unsaturated fats, produces the majority of trans fat. A hydrogenated oil is created as a result of this process.

Margarine, shortening, baked items, doughs, and fried meals all include them. Trans fat should be avoided if it appears on the label.

The macronutrient split refers to the recommended quantities of these various macronutrients. The USDA’s suggestions are an excellent place to start:

  • Carbohydrates: 45-65%
  • Protein: 10-35%
  • Fat: 20-35%

Calculate Your Macronutrient Needs

Here’s an example of how to calculate macronutrients for a 2,000-calorie diet consisting of 40% carbs, 30% protein and 30% fat.


  • 4 calories per gram
  • 40% of 2,000 calories = 800 calories of carbs per day
  • Total grams of carbs allowed per day = 800/4 = 200 grams


  • 4 calories per gram
  • 30% of 2,000 calories = 600 calories of protein per day
  • Total grams of protein allowed per day = 600/4 = 150 grams


  • 9 calories per gram
  • 30% of 2,000 calories = 600 calories of protein per day
  • Total grams of fat allowed per day = 600/9 = 67 grams

In this scenario, your ideal daily intake would be 200 grams of carbs, 150 grams of protein and 67 grams of fat.
