How to calculate your Basal Metabolic Rate (BMR)

Basal Metabolic Rate (BMR) is the number of calories your body burns while doing absolutely nothing. It is the amount of calories your body uses per day, at rest, while maintaining essential body functions. It can be thought of as the number of calories your body would use up if you spent 24 hours asleep and motionless.

BMR scales with factors such as age, weight, height and gender.

Although many other factors (such as stress, illness, etc) are all said to affect Basal Metabolic Rate, they do not generally appear in the standard BMR calculations as they would be very difficult to quantify accurately.

As such the BMR is only an approximation, but a generally useful one nonetheless.

– Metric measurements, kg and cm
BMR = 655.1 + (9.563 x weight) + (1.850 x height) – (4.676 x age)
