How are the macros calculated?

The ratio of protein is set at 0. 825 grams, per pound of body mass. Fats are set at twenty-five percent of everyday energy expenditure. Carbohydrate is calculated from the remainder. Daily energy expenditure is calculated by weight, height, exercise output, and age.

When should you calculate your macro nutrient intake?

This way you are not able to consume the essential macro nutrients and balance them. If you calculate your macro nutrients intake you can plan your meals and stay away from these cravings which ruin your appetite

For a most individual, they aren’t well aware of how much protein to consume and have the wrong idea. To get an idea of how much protein to consume, you should use macro calculator as individuals tend to consume carbohydrates and fats more than the proteins

When should you not calculate your macro nutrient intake

When you aren’t motivated enough

When you still consume big mac with a lettuce on and consider it healthy or eat carrots with healthy consumption of pancakes and don’t know the fact butter is a carb or can’t let go of junk food, you aren’t ready enough. Before using the macro calculator, you should motivate yourself then stick to the diet plan.

When you are a macro nutrient veteran

When you are already aware of which diet you should consume with what limit of each macro nutrients, you have mastered balancing your life style according to the healthy eating, using macro calculator is useless for you.

Advantages & Disadvantages of calculating macros:

  • You can track your food consumption

  • Those who are new to dieting and eating healthy don’t have an idea how to track and what amount of calories and macros to intake, the macro calculator acts as a perfect guide for them

  • Using a macro calculator and calculating macros aids in keeping your body in the desired shape.

  • It gets stressful sometimes and demotivating to keep a daily track of food

  • You start to focus on macro intake and start to ignore the quality of the food.



Fats are less available compared to carbohydrates in the body for instant use. The reason for this is that the transformation of fats into energy is more complex compared to carbohydrates. Fats must be broken down into triglycerides to glycerol then into free fatty acids, which can be used by the body for energy consumption. Fats provide more energy than carbohydrates and are also used as building blocks of essential hormones.


Under extreme circumstances, protein can also be used for the creation of energy. Protein must convert into fatty acids or glucose for energy consumption. Amino acids can also be utilized for energy conversion.


In the body, the carbohydrates are converted into simple sugar molecules, glucose, which is found in every tissue present in the body. The excess glucose is converted into glycogen and is stored in the liver. Some of the glycogen is stored in muscles and is used in the formation of ATP, a compound which body derives energy from. The stores of glycogen tend to deplete after vigorous exercise. This calculator calculates what amount of carbohydrates is needed for an individual with different goals, whether it's for exercise or weight loss.
