Calorie calculator

How are calories calculated?

First we calculate your basal metabolic rate (BMR) with the Mifflin-St Jeor equation, the most accurate for most people. Then we multiply it by your activity factor to get the calories you need to maintain your weight.

To lose about half a kilogram a week you need a deficit of roughly 500 calories a day. Going below 1,200 calories for women or 1,500 for men is not recommended without medical supervision.
