Macro vs Calories

Today video is a quick overview of macros vs calories?

So you properly the terms, macro and calories being used a lot, form a wide range of diets and food plans, but what are they?

Well let’s start off with macro, what are macro?

Macros stand for Macronutrients,

Nutrients are consumable substances our body use for energy, growth, and bodily functions. Depending on the nutrient, these substances are needed in small amounts such as vitamins and minerals or larger amounts. Those that are needed in large amounts are called macronutrients.

Macronutrients measure out food intake by breaking them down into three main groups, which are;

  • Protein, which are essential the building blocks of life
  • Lipids (Fats) which are essential to body function and hormone production
  • And finally Carbohydrates, which provides energy and fibre and vitamins

These are measured in grams.


Now calories are a unit of measure of energy.

Scientific speaking, there are two units of calories:

The first is a standard unit calorie =1cal is the amount of energy required to raise one gram of water by one degree Celsius.

The second unit is the kilocalorie = 1Cal is the amount of energy required to raise one kilogram of water by one degree Celsius.

1 kilocalorie = 1,000 standard calories.

Where 1 Calorie = 4.1 joules, however the big difference between Marco and calories is that calories don’t distinguish between the energy sources, whether that be protein, carbohydrates or fats.

Out the two I mainly use macros as my unit of measure, but that said both are linked can be convert quite easily using the following equation

  • Protein 1 gram = 4 Cal
  • Carbohydrate 1 gram = 4 Cal
  • Fats 1 gram = 9 Cal
  • Alcohol: 1 gram = 7 Cal

So an example of this is if you look at a food label and it lists 10 grams of protein, 0 grams of carbohydrates, and 0 grams of fat, that food would contain 40 calories.

Now the recommend amount of calories for an adult are the following:

For an adult male is 2500 and for an adult female is 2000.

Now I hopefully that helped clear up both calories and macros, so what’s your option? Leave you interesting comments below and for more awesome fitness tips and advice with weekly videos please like and subscribe. And thank you for watching.
