BMR Calculator

Find out how many calories your body needs at rest just to fuel its normal metabolic activity.

Basal Energy Expenditure - also known as basal metabolic rate (BMR) or (incorrectly) as resting metabolic rate (RMR) - is the minimum number of calories your body needs at rest to maintain functions such as heartbeat, breathing and temperature.

Knowing this number can help with a weight management programme because it can help you to calculate how much energy you spend in a day.
