How to Track Macronutrients - The Definitive Step by Step Guide
Updated: Jun 6, 2021
Knowing how to track macronutrients - proteins, carbohydrates, and fats - is important for eating a well-balanced diet and hitting your specific dietary goals.
But how do you count macronutrients? Especially for home-cooked meals? And how do you track macronutrient intake over time?
This step-by-step guide walks you through this process to show you how to track macronutrients from your diet. It essentially comes down to two primary questions: What is the macronutrient breakdown of the food you ate? And, how much of it did you eat?
Step 1: Identify the individual food items in your meal.
If the food is pre-packaged, with a nutrition label, skip this step. But, if you prepared your meal from a recipe (like the one below for Ikarian soufico), make note of each food item in the meal. Either on paper, or using a spreadsheet like Google Sheets or Microsoft Excel, list each item in the first column under the heading title like, Food Items.

Step 2: Calculate the quantity of each serving of foods with nutrition labels.
If the food is pre-packaged, look at the nutrition label. You will see “serving size,” and “servings per container.” Take how much (quantity) you ate, and divide that by the serving size. Save that answer. You will multiply each macronutrient by this answer to determine how much of it you ate. For example, our earlier recipe called for ½ cups of extra virgin olive oil. See how this equates to 56 grams of fat.

Step 3: Navigate to the USDA Food Search tool for fresh food item.
For fresh foods without a nutrition label, navigate to the USDA Food Search tool at https://ndb.nal.usda.gov/ndb/search/list.

Step 4: Search for each food item.
Edit Select Source for Standard Reference, and enter the name of a food item into Enter one or more terms**_._**.
Find the food item description that best fits your food. For fresh fruits and vegetables, often the term includes “, raw.” Click on that food item.

Step 5: Search for and modify the quantity of the item to match your recipe.
Scroll horizontally in the table to find the quantity that best matches your recipe. To modify the column, enter a value into the serving size box and hit Enter.

Step 6: Identify the Breakdown of Macronutrients.
Match the value in the column for your desired quantity with the rows for protein, total lipid (fat), and carbohydrate, by difference.

Step 7: Record these values for each food item.
Record these three values for each food item in the recipe, and repeat this cycle for each food item.
