A Beginner’s Guide to Counting Macros for Diet and Fitness

If you've ever tried tracking calories and still felt stuck with your fitness or nutrition goals, counting macros might offer a better way to tune into what your body really needs. Short for "macronutrients," macros refer to the three major nutrients protein, carbohydrates, and fat that provide energy and help your body function. Learning how to count them can help you lose fat, build muscle, or just feel more in control of your nutrition.

What Are Macros?

Each macronutrient plays a different role in your body and contributes differently to your total calorie intake:

• Carbohydrates: 4 calories per gram – your body’s main energy source

• Protein: 4 calories per gram – crucial for muscle repair, hormones, and enzymes

• Fat: 9 calories per gram – supports cell function, vitamin absorption, and hormone health

To hit your goals, you’ll aim to consume the right balance of these macros not just fewer calories overall.

Step 1: Find Your Daily Calorie Needs

Before you can count macros, you need to know your daily energy needs. This depends on:

• Age

• Body size

• Sex assigned at birth

• Activity level

• Pregnancy or breastfeeding

On average:

• Women need 1,600 to 2,400 calories/day

• Men need 2,000 to 3,000 calories/day

Use a reputable calorie calculator or consult a registered dietitian to get a personalized number.

Step 2: Choose Your Macro Ratio

Your macro split depends on your goal:

Example:
Let’s say your goal is 2,000 calories/day with a 40% carbs, 30% protein, 30% fat split:

• Carbs: 800 calories ÷ 4 = 200g

• Protein: 600 calories ÷ 4 = 150g

• Fat: 600 calories ÷ 9 = 67g

Step 3: Track Your Macros

Once you have your numbers, use a food tracking app (like MyFitnessPal or Cronometer) to log your daily intake. Check nutrition labels or use a food scale for accurate measurements, especially early on.

For foods without labels like produce or meat use online databases such as the USDA’s FoodData Central.

How to Eat for Your Macros

Protein
Builds and repairs tissues, supports metabolism
Found in: meat, fish, eggs, dairy, tofu, lentils, beans

Carbohydrates
Your main energy source, especially during workouts
Found in: fruit, grains, pasta, potatoes, legumes

Fat
Essential for hormone production and absorbing vitamins A, D, E, and K
Found in: olive oil, avocado, nuts, seeds, fatty fish

Pro Tip: Not all calories are equal in quality. A donut and a sweet potato might have similar carbs, but very different impacts on blood sugar and satiety.

When to Adjust Your Macros

As your body changes or your goals shift, your macro needs may too. You might need more protein during strength training or fewer carbs on sedentary days. Life stages like pregnancy, illness, or aging can also affect what your body needs.

If you're unsure, check in with a registered dietitian who can personalize your plan.
