BMR calculator

How many calories does your body need?

Get to grips with your metabolism

Your body uses energy, even while you’re sleeping, and this energy needs to be replenished through eating for the body to survive.

Basal metabolic rate (BMR) is the minimum number of calories your body needs to maintain those basic, life-sustaining functions such as breathing, digestion, and blood flow. It is, in essence, your metabolism.

Our BMR calculator can help you determine how many calories you want to burn or consume based on your BMR score, exercise routine and health goals, as well as giving you a better understanding of your body.

How is BMR calculated?

We’ve used the Mifflin-St Jeor equation, which calculates BMR as follows:

Men: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5
Women: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161

So, a 40 year old female who stands 5’5’’ (165.1cm) and weighs 135.1 lbs (61.3kg) would have a BMR of 1300kcal, which is the minimum number of calories she would need to eat in a day to maintain her weight.
