Lifesum’s calculations are based on the Mifflin - St Jeor equation and activity level. This equation is used in clinical settings to determine induviduals’ caloric needs based on their basal metabolic rate (BMR) and activity level. Since it is one of the most reliable methods to calculate with the user information we have we have decided to use it for our calculations:
BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) + 5 (man)
BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) - 161 (woman)
The calorie goal is calculated depending on the plan the user is choosing (gain, lose, maintain/be healthy).

The calorie goal is calculated depending on the plan the user is choosing (gain, lose, maintain/be healthy).
Also: the calorie goal will automatically change when you lose/gain weight over time and are following the calorie goal calculated by the app.
Please note: as soon as you set a static calorie goal yourself under Settings/Personal Details the goal will remain static and not change. In order to change this you need to enter 0 as calorie goal > the app will then automatically calculate your calorie goal based on the personal details again.
Please note: that adding a partner like Fitbit etc will automatically reduce the calorie goal as you will earn extra calories through movement during the day and thus be able to consume more again.
