Macro Calculator
Macronutrients โ protein, carbohydrates, and fat โ are the three main nutrients your body needs in large quantities for energy, growth, and repair. Knowing how many grams of each macro to eat per day helps you design a diet that supports your specific goals, whether that is weight loss, muscle building, or general health maintenance.
How Macros Are Calculated
Each macronutrient provides a different amount of energy: protein and carbohydrates each provide 4 kcal per gram, while fat provides 9 kcal per gram. This calculator converts your chosen percentages into grams based on your total daily calorie target. Make sure your percentages add up to 100% for accurate results.
Recommended Macro Splits
There is no single ideal macro split โ it depends on your goals and activity level. A common balanced approach is 30% protein, 40% carbohydrates, and 30% fat. For endurance athletes, a higher carbohydrate percentage may be beneficial. For those focused on fat loss, higher protein helps preserve muscle mass. The Danish dietary guidelines (De officielle kostrรฅd) recommend a balanced diet rich in vegetables, whole grains, and lean protein sources.
