Macro Nutrient Split Ratio
Split your daily calories into protein, carb, and fat grams based on a target macro percentage split.
How a calorie target becomes a macro breakdown
This takes your daily calorie target and splits it into protein, carbohydrate, and fat grams based on your chosen ratio, converting each macro's calories back to grams using its energy density — roughly 4 cal/g for protein and carbs, 9 cal/g for fat.
Why there's no single "ideal" split
A macro ratio suited to strength training differs from one suited to endurance training or general maintenance. There's no universally correct split — treat the presets here as reasonable starting points to adjust based on how your body responds.
