What are Macros?

I know you have heard the term 'Macro' some where or another, whether on social media or in the gym.  So what exactly is a 'Macro'?

A macronutrient (aka Macro) is identified by nutritionists as a carbohydrate (aka carb), protein and fat.  All of these are used as fuel by your body for growth, metabolism and operation.  Each macro contain a set number of units of energy known as a calorie.  Below is the amount of calories each one provide in grams.

Carbs = 4 calories per gram
Protein = 4 calories per gram
Fats = 9 calories per gram


Now you know what a Macro is! It's that simple.  Look for my next blog so you can figure out how to calculate how many grams of each you are getting and why athletes are more concerned with macronutrients then calories.
