Turn your chosen calorie and percentage allocation into grams.

How it works and limits

Enter your own energy allocation and percentages totaling 100%. Grams = kcal × fraction ÷ energy per gram: protein 4, carbohydrate 4, fat 9. The tool performs arithmetic and does not recommend a diet, calorie restriction or macro split. Food labels and individual absorption vary.

Worked example

calories: 2000
protein: 25
carbs: 50
fat: 25
