Macro Calculator: Protein, Carbs, and Fats for Your Goals
Macronutrients—protein, carbohydrates, and fats—are the three energy-providing nutrients that fuel every physiological function. Understanding how to calculate and optimize your macros transforms nutrition from guesswork into precision science.
Protein: The Muscle-Building Macro
- Sedentary: 0.8g per kg
- Strength Athletes: 1.6-2.2g per kg
- Fat Loss: 2.0-2.4g per kg to preserve muscle
Carbohydrates: The Energy Macro
- Ketogenic: Under 50g daily
- Low-Carb: 50-150g daily
- Moderate: 150-250g daily
- High-Carb: 250-400g+ daily for endurance athletes
Fats: The Hormonal Macro
Fats provide 9 calories per gram and are essential for hormone production, cell membranes, and vitamin absorption. Never drop below 20% of total calories.
Individual Variation: Macro needs vary based on genetics, training history, and hormone status. Track progress for 4-6 weeks and adjust based on results.
