A simple guide to macronutrients
A macro split describes the proportion of calorie energy assigned to protein, carbohydrate and fat. This calculator converts a split you choose into grams.
The idea in practice
Enter a calorie amount and choose protein and fat percentages. Carbohydrate automatically receives the remaining percentage. Protein plus fat cannot exceed 100%.
AT A GLANCEProtein & carbohydrate: kcal ÷ 4 · Fat: kcal ÷ 9
Keep the result in perspective
The default percentages are an editable example, not a personal nutrition prescription. Food-label calories can differ because of rounding, fibre, alcohol and other components.
