Split calories into protein, carbs and fat.

Private by design — everything is calculated on your device, nothing is stored
kcal

Try: Calorie target=2000, Protein %=30, Carbs %=40, Fat %=30 → 2,000 kcal, 150 g (30%), 200 g (40%), 67 g (30%)

How to use

Macros are the three nutrients that supply energy. This splits a calorie target into grams using their densities: protein and carbs 4 kcal/g, fat 9 kcal/g.

Formula

grams = kcal × % / density

FAQ

Why must they total 100%?

Percentages are shares of the same calorie total.

Typical split?

A balanced plan is often 30/40/30; athletes shift protein up.
