Macronutrients: The Basics

Updated: Jan 14

Nutrition is best presented like an onion - one layer at a time 😉


(That's a Shrek reference I hope you got) 😂


So for maximum retention and minimum tears, today we will be focusing on the first layer:

  1. What are macronutrients?

  2. What (in the context of exercise) does our body use them for?

  3. How did calories somehow got into this mix? 🤨


 

First things first, there are 3 main macronutrients:

  • Protein

  • Carbohydrates

  • Fats

These are the same proteins, carbohydrates, and fats that you see on nutrition labels.


Macronutrients, often called "macros" for shorthand, are nutrients that are essential for your survival (obviously, this is important).

We need macronutrients in large quantities (think macro = large) to carry out necessary physiological functions.

Making sure we have the right quantity of each macronutrient is important for general health, but it is especially important for any specific exercise performance or body re-composition goals you may have (particularly protein).

MACROS + CALORIES: THE GIST What if told you, the diligent calorie counter, that you have been unknowingly and haphazardly counting macros this whole time when you log food? 😯 Yep. Go to your app right now and I bet you will find listed somewhere some macronutrient ratios in relation to your daily calories.

You see, each macro has an assigned caloric value that is always true. In other words, each one provides your body a specific amount of energy. Always.

Macro's assigned caloric values are: For every 1g of carbohydrate, your body receives 4 calories. For every 1g of protein, your body receives 4 calories. For every 1g of fat, your body receives 9 calories. Remember that a Calorie = one unit of food energy. Calories are what give your body the energy it needs to exercise and carry out basic functions to keep you alive.

Fats will always provide 9 calories per gram, just as protein and carbohydrates will always provide 4 calories per gram no matter the food type:

If 1 serving of candy is 15g of fat and 1 serving of peanut butter is also 15g of fat, then they both provide your body 135 calories. More on that in a later series 😉 SO HOW MANY OF EACH MACRO DO I NEED? Well, it depends. It depends on:

  1. Age

  2. Sex

  3. Height and weight

  4. Current non-purposeful activity level (i.e. activity you do outside of the gym or NEAT)

  5. Fitness goals

The relationship between macros and calories is important for those wanting to lose weight and/or have body re-composition because:

  • To lose weight you must be in a caloric deficit (expending more calories than you are consuming).

  • To have body recomp occur you must have the proper ratio of macronutrients.

SUMMARY + THE BOTTOM LINE

  • There are 3 Macronutrients: Protein, Carbohydrates, Fats

  • Macronutrients are important because they are essential for our survival

  • We need macronutrients in large quantities

  • Macros have assigned calorie amounts that are always constant:

-1g Fat = 9 calories

-1g Carb = 4 calories

-1g Protein = 4 calories

  • "Counting macros” is really just another, more nutritionally well rounded way of counting calories! 🤯

  • Macros are truly individualized and will vary from person to person (my macros will not work for you and vice versa because you are not me. Are you seeing a theme here?)
