How to Track Macros: A Beginner-Friendly Step-by-Step Guide
Tracking macros can feel overwhelming at first, but with the right tools and a little practice, it becomes second nature. The goal isn’t perfection, it’s building awareness of what’s in your food so you can stay consistent and make progress toward your goals.
What You’ll Need
A digital food scale – to measure your portions accurately.
A way to track your food – an app like MyFitnessPal, MacrosFirst, or Cronometer.
Your personal macro goals – protein, carbs, and fats set by your coach or calculated for your specific needs.
Step 1: Understand the Basics
“Macros” stands for macronutrients, the three main nutrients that make up the calories in food:
Protein (4 calories per gram): Builds and repairs muscle, supports recovery.
Carbohydrates (4 calories per gram): Primary energy source, fuels workouts and daily activity.
Fats (9 calories per gram): Essential for hormones, brain function, and long-term energy.
Every food you eat contains some combination of these three. Tracking simply means monitoring how many grams of each you eat daily.
Step 2: Know Your Daily Targets
Think of macros like a daily budget:
Protein = income you must hit to keep your body functioning and recovering.
Carbs and fats = flexible spending categories that can shift slightly depending on the day.
Example daily target:
150g protein
200g carbs
70g fat
(≈ 2,000 calories total)
Your goal is to “spend” your macros throughout the day without going far over or under.
Step 3: Weigh and Measure Your Food
Place your empty plate or bowl on the scale.
Press tare/zero to clear the weight.
Add your food until you reach the portion you want.
Enter that amount into your tracking app.
Pro Tip 1: Most people weigh food before cooking, but what matters most is consistency. If you always log chicken cooked, keep it cooked. If you log it raw, always log it raw. What you don’t want to do is flip-flop between the two, since weights change with water loss during cooking.
Pro Tip 2: Don’t forget oils, dressings, sauces, or creamers—they add up quickly.
Step 4: Track in an App
Using MyFitnessPal as an example:
Open the app and select the meal you’re logging (breakfast, lunch, etc.).
Search for the food or scan the barcode on the package.
Enter the amount you measured (e.g., 150g chicken breast).
The app will break it down into protein, carbs, and fats automatically.
Repeat this process for everything you eat or drink.
Step 5: Learn to Read Labels
Food labels provide serving size and macros per serving. For example:
Serving size: 30g cereal
Carbs: 22g
Protein: 3g
Fat: 1g
If your portion is 45g, you ate 1.5 servings: 33g carbs, 4.5g protein, 1.5g fat.
Step 6: Plan Ahead for Success
Pre-log meals: Enter tomorrow’s meals the night before to stay on track.
Batch cook: Prepare food in bulk, weigh it once, and divide into portions.
Save meals in your app: Makes logging repeat meals quick and easy.
Step 7: Avoid Common Mistakes
Guessing portions instead of weighing.
Forgetting condiments, cooking oils, or snacks.
Switching between weighing raw vs. cooked food.
Using unverified entries in tracking apps (always check accuracy).
Step 8: Focus on Consistency, Not Perfection
Macro tracking is a skill—don’t expect to master it overnight. If you’re within 5g of each macro target by the end of the day, you’re doing great. The more consistent you are, the more effective this tool becomes.
Example: Tracking a Meal
150g cooked chicken breast → 40g protein, 0g carbs, 3g fat
100g cooked rice → 28g carbs, 3g protein, 0g fat
10g olive oil → 0g protein, 0g carbs, 9g fat
Meal Total: 43g protein, 28g carbs, 12g fat
Over time, you’ll start to know portion sizes by sight, but in the beginning, measuring is key. Tracking your macros gives you awareness, structure, and the ability to adjust based on your goals.
