About

A macronutrient calculator takes the guesswork out of dieting by converting your daily calorie goal into precise grams of protein, carbohydrates, and fat. Whether you want to lose fat, maintain your current weight, or build muscle, hitting the right macro split is as important as hitting your overall calorie target. Use this free tool to get personalised macro targets in seconds.

FAQ
What are macronutrients?+

Macronutrients are the three main nutrients your body uses for energy: protein (4 kcal/g), carbohydrates (4 kcal/g), and fat (9 kcal/g). Tracking their ratios — not just total calories — helps optimise body composition and performance.

What macro split should I use to lose fat?+

A higher-protein split (around 40% protein, 35% carbs, 25% fat) is popular for fat loss. The extra protein helps preserve lean muscle while in a calorie deficit, keeping you fuller and protecting your metabolism.

What is TDEE and why does it matter?+

TDEE (Total Daily Energy Expenditure) is the total number of calories you burn each day, including exercise. It's calculated from your BMR (Basal Metabolic Rate) multiplied by an activity factor. Eating at, above, or below your TDEE determines whether you lose, gain, or maintain weight.

How accurate are these macro calculations?+

The TDEE estimate uses the Mifflin-St Jeor equation, which is considered the most accurate general-population formula. Macro percentages are evidence-informed guidelines, but individual needs vary. Use these numbers as a starting point and adjust based on real-world results over 2–4 weeks.
