How it works
The science behind your number.
No fad maths — CalorieCalc uses the same method dietitians rely on, so the target you log against actually holds up.
We estimate your baseline
Your age, gender, height and weight feed the Mifflin–St Jeor equation to find your resting metabolic rate — the calories you burn just being alive.
We factor in how you move
Your activity level scales that baseline up, from mostly-sedentary desk days through to hard daily training, to reach the calories you actually burn.
We match it to your goal
Losing weight trims a sensible deficit, gaining adds a surplus, and maintaining holds steady — then we split the total into protein, carbs and fat so you know what to log.
