How to Set Your Macro Targets and Calories: A Step-by-Step Guide
If you’re serious about your fitness journey—whether that means losing weight, gaining muscle, or maintaining your current physique—understanding your macros is a game-changer. Calculating your macronutrient targets will help you fuel your body intentionally and efficiently. Let’s dive into everything you need to know to set your macro goals.
What Are Macros?
Macros, short for macronutrients, are the nutrients your body needs in large amounts to function and thrive. They include:
Protein: Builds and repairs muscle.
Carbohydrates: Your body’s primary energy source.
Fats: Essential for hormone production and overall health.
Tracking macros helps you go beyond simply counting calories to ensure your body is getting the right balance of nutrients for your goals.
Step 1: Calculate Your Caloric Needs
The first step in setting your macros is determining your Total Daily Energy Expenditure (TDEE)—the number of calories your body needs to maintain your current weight.
1. Find Your Basal Metabolic Rate (BMR)
BMR represents the calories your body burns at rest. Use the Mifflin-St Jeor Equation:
For Women:
BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) − 161For Men:
BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) + 5
2. Adjust for Activity Level
Multiply your BMR by an activity factor:
Sedentary (little to no exercise): BMR × 1.2
Lightly active (exercise 1–3 days per week): BMR × 1.375
Moderately active (exercise 3–5 days per week): BMR × 1.55
Very active (exercise 6–7 days per week): BMR × 1.725
Extra active (intense daily exercise or a physical job): BMR × 1.9
The result is your TDEE—the number of calories to maintain your weight.
Step 2: Adjust Calories for Your Goal
Once you know your TDEE, adjust your calories based on your fitness goal:
For Weight Loss: Subtract 500 calories from your TDEE to create a calorie deficit. This leads to a steady loss of about 1 pound per week.
For Weight Gain: Add 250–500 calories to your TDEE to support muscle growth or weight gain.
For Maintenance: Stick to your TDEE.
Step 3: Set Your Macro Ratios
Divide your total calories into protein, carbohydrates, and fats. Your ratios will vary depending on your goal:
Macro Ratios for Common Goals
Weight Loss: Protein 40%, Carbs 30%, Fats 30%
Muscle Gain: Protein 30%, Carbs 50%, Fats 20%
Maintenance: Protein 30%, Carbs 40%, Fats 30%
Step 4: Convert Percentages to Grams
Macros have different calorie values per gram:
1 gram of protein = 4 calories
1 gram of carbohydrate = 4 calories
1 gram of fat = 9 calories
Example for Weight Loss
Let’s say your calorie target is 1,800 calories:
Protein (40%): 40% × 1,800 = 720 calories ÷ 4 = 180g of protein
Carbohydrates (30%): 30% × 1,800 = 540 calories ÷ 4 = 135g of carbs
Fats (30%): 30% × 1,800 = 540 calories ÷ 9 = 60g of fat
Step 5: Track Your Macros
Once you’ve set your targets, track your daily intake to stay consistent:
Use apps like MyFitnessPal or Cronometer to log your meals.
Weigh your food with a digital food scale for accuracy.
Prep meals in advance with meal prep containers and store them in a lunch bag for easy access.
Pro Tips for Success
Be Flexible: It’s okay if you don’t hit your macros perfectly every day. Focus on weekly consistency.
Prioritize Protein: Protein is crucial for muscle retention and feeling full. Make it your focus, especially when cutting.
Adjust as Needed: Recalculate your macros every few months, especially as your weight or activity level changes.
