Ever stare at a nutritional label and wonder how they determine just how many calories are in that bag of jerky?

It can seem overwhelming, but the answer lies right in front of you if you can handle a bit of simple math.


What is a Macronutrient?

Simply put, macronutrients (or “macros”) are nutrients that provide us with energy. More specifically there are 3 macros:

  • Fats
  • Carbohydrates
  • Proteins
  • Alcohol – alcohol provides energy in the form of calories but is not required for survival (sorry guys!), so it’s not technically a macro

Counting Macros


  • 1 gram fat = 9 calories
  • 1 gram carbohydrate = 4 calories
  • 1 gram protein = 4 calories
  • 1 gram alcohol = 7 calories
