Calculating Macros: Protein, Fat, and Carbs
Learn how to calculate macros from calorie targets, body weight, and common macro splits for maintenance, fat loss, and muscle gain.
Searching calculating macros usually means you want daily targets for protein, fat, and carbohydrates.
Calories Per Gram
Each macronutrient provides energy:
| Macro | Calories per gram |
|---|---|
| Protein | 4 |
| Carbohydrates | 4 |
| Fat | 9 |
Simple Macro Setup
One practical approach is:
- Set total calories.
- Set protein.
- Set fat.
- Use the remaining calories for carbs.
Example
Suppose your calorie target is 2,000 calories.
- Protein: 140 g = 560 calories
- Fat: 60 g = 540 calories
Calories remaining for carbs:
2,000 - 560 - 540 = 900
Carbs:
900 / 4 = 225 g carbs
Why Macro Math Helps
Macro targets can be useful for:
- Fat loss
- Muscle gain
- Meal planning
- High-protein diets
- Performance nutrition
The Bottom Line
To calculate macros, start with your calorie target, assign protein and fat, then use remaining calories for carbs. Our TDEE Calculator can help you estimate the calorie starting point.
How to Calculate: Step-by-Step Guide
Set calorie target
Start with your maintenance, fat-loss, or muscle-gain calories.
Choose protein and fat targets
Set protein and fat first, often using body weight and a minimum fat intake.
Fill the rest with carbs
Use the remaining calories for carbohydrate grams.
