How are my daily calories calculated?

The calculator uses the Mifflin-St Jeor equation to estimate your Basal Metabolic Rate (BMR) and then multiplies it by your activity level to give your Total Daily Energy Expenditure (TDEE).

TDEE stands for Total Daily Energy Expenditure. It is the total number of calories your body burns in a day including exercise and daily activity.

How many calories should I eat to lose weight?

A common approach is to eat 500 calories below your TDEE per day, which creates a deficit that leads to approximately 0.5 kg (1 lb) of fat loss per week.
