How to Count Macros: A Step by Step Guide

What exactly is a macro diet and should you be on one? While macro counting is gaining popularity on social media, the concept is not exactly new. Macros have been around nearly as long as calories, and tracking them has long been practiced in the fitness and dieting world. Whether you are new to the concept of macros or just looking to take your fitness journey to the next level, here's everything you need to know.

Calculate Your Daily Macros

Use the calculator below to learn your exact protein, fat, and carbohydrate needs in minutes! 

What Are Macros and Why Should You Care?

The term Macronutrients (macros) stems from the Greek word "makros", meaning large. Macronutrients are nutrients you require in large amounts. They are needed in such large quantities because they supply all of your daily energy.

Macronutrients are essentially your calories from food broken up into three major nutrient groups:

  • Carbohydrates
  • Protein
  • Fat

Each macronutrient provides important nutrients for daily function and survival, and getting the right balance of all three is crucial for maintaining lean muscle, burning fat and staying healthy. Meaning they may play a key role in determining your body composition. They also play a part in supporting better energy control, mood balance, appetite, and overall fitness performance.  

Carbohydrates and fat both supply valuable energy in the form of sugars and fatty acids. Carbs are a favorite source of fuel for your brain and also provide quick energy as needed for workouts and daily movements. Fat acts as a long-lasting source of fuel, and also plays a role in nutrient storage and building hormones.  

Your daily protein needs are directly related to your body weight and fitness level. Protein is the builder nutrient - working to actively maintain, repair, and create just about every single cell in your body. This is exactly why high protein intake is recommended to help build muscle. Higher protein consumption may also support fat loss.

Macros vs Calories

Weight loss is achieved by decreasing the quantity of what you eat (aka reducing your daily calorie intake), whereas fat loss requires you to change the quality of your diet. In other words, fat loss or muscle gain can be triggered when you start tracking your macros because of the way your body utilizes them.


Calorie control is the first step in changing your body. Fine-tuning your macronutrient intake is the next level up.

Macronutrients vs. Micronutrients

There is a lot of talk around an "if it fits your macros" (iifym) approach to dieting, but macronutrients are only one piece of the puzzle. There are also micros to consider when it comes to nutrition needs.

Micronutrients (micros), on the other hand, are nutrients needed in smaller amounts, and they do not provide a source of calories to the diet. These include all of the essential vitamins and minerals we need each day. 

You can likely eat a lot of unhealthy foods and still hit your macros, but you'll get better results if you focus on diet quality as well. I'm talking about choosing more nutrient-dense foods instead of just focusing on your daily macros. 

Is Alcohol a Macro?

Alcohol is also technically a macro since it provides calories, but is not considered an essential nutrient for health so it is often left out of macro diet plans.

You should still track your calorie intake from alcohol since this will definitely affect your progress and ability to lose weight or gain muscle. Alcohol provides a significant amount of calories - in fact, each gram of alcohol provides seven calories per gram.


If you are looking to lose body fat you may want to consider drinking less alcohol. Your body will prioritize metabolizing toxins from drinking before other macros, slowing down your metabolism and increasing how much fat you are storing from food. This can prevent you from burning as much fat.

How to Count Macros

Counting macros is the process of tracking how many grams of each macronutrient you consume per day. And because protein, fat, and carbohydrates each provide a certain amount of calories per gram, you are also tracking how many calories per day you consume.

Counting macros is an easy way to count calories and nutrition intake at the same time.

Once you know your calorie goals, you can easily count your macros using the following three steps:

Step 1. Learn How Many Calories Per Macro 

The calorie breakdown of your macros is as follows:

Carbohydrates and protein provide roughly four calories per gram - meaning a food or beverage item with 10g of protein will provide 40 calories from protein.

Fat is the highest calorie nutrient with nine calories for every gram - more than twice the amount of energy as protein and carbohydrates. Thus, a food or beverage containing 10g of fat will provide 90 calories from fat.


Step 2. Calculate Total Macro Calories

You can calculate the amount you are eating by using the nutrition facts label. It really is that simple, anything that has a nutrition facts label also has macronutrients listed. In fact, this is exactly what the FDA uses to calculate the number of calories in your food. 

For example, the nutrition label for a half-cup serving of whole-grain cereal says it provides 3 grams of fat, 13 grams of carbs, and 3 grams of protein. You can calculate the calories for each macro by multiplying each by their designated macronutrient calorie count.

  • 3g of fat x 9 calories per gram = 27 calories
  • 13g of carbs x 4 calories per gram = 52 calories
  • 3g of protein x 4 calories per gram = 12 calories

These calorie amounts combined should equal the number of total calories for the food - 90 calories per serving!

Step 3. Assess Macro Ratio (%)

To find the macro ratio percentage for each, you simply divide each calorie amount by total calories (90) and then multiply by 100.

Note: this percentage is different from the percent daily value on the label, which is looking at your total daily needs.

  • 27 fat calories / 90 calories x 100% = 30% of calories from fat 
  • 52 carb calories / 90 calories x 100% = 57% of calories from carbs
  • 12 protein calories / 90 calories x 100% = 13% of calories from protein

The percentage of all three - protein, fat and carbohydrates, should total 100%. 


TIP: To be as accurate as possible, make sure you are measuring for the right portion size! 

Using a Macro Tracking App

In short, the easiest and most useful way to count macronutrients is using a macro tracking app. It's also a good way to ensure you are sticking to your diet so that you get results! 

Tracking apps can be especially helpful for options that don’t have a nutrition facts label - such as fresh meats and produce. Using a searchable database from a food tracking app can help you find the nutrition breakdown of these foods.

You can also find the nutrition information for any food online through the USDA Food Composition Databases.

Additionally, some tracking apps will use a barcode scanner feature that allows you to quickly input nutrition info for packaged foods. 

Pssst...The Trifecta app has over 6 million food items you can search for, plus a barcode scanner for better tracking! It also has a quick add macro feature that allows you to input the carbs, fat, and protein for any food to count your macros in seconds. 

TIP: Weighing and measuring your food will help you to be more precise, when tracking items without a nutrition facts label.

How Many Macros Do You Need?

Through a series of simple questions to assess your activity level and health goals, you can quickly determine your macro needs using a macro calculator.

Or you can roughly estimate your macros using the simple formula below.

Step #1 - Choose your objective. Are you trying to lose fat, gain muscle, or do you want to maintain your weight and/or improve performance? 

Step #2 - Estimate how many calories you need per day to lose, gain, or maintain your weight. You can find this using a total daily energy expenditure calculator or TDEE calculator

Step #3 - Once you have your target total daily intake, you can estimate your macro needs using the following chart:
