  • Men: BMR = 66 + (13.7 x body weight in kg) + (5 x height in cm) – (6.75 x age in years)
  • Women: BMR = 655 + (9.6 x body weight in kg) + (1.8 x height in cm) – (4.7 x age in years)

For example, if we want to calculate the BMR of a woman who has a body weight of 72 Kilos, measures 1.65 meters and is 32 years old, it would be:

BMR = 655 + (9.6 x 72) + (1.8 x 165) – (4.7 x 32) = 655 + 691.2 + 297 – 150.4 = 1,493 calories per day. Those are the calories your body consumes at rest.

There is a more modern formula called Mifflin-St equation. Jeorwhich you can apply in this online calculator.

The BMR or TMB It marks the calories at rest. We have to multiply them by a number, according to our daily activity (valid for men and women):

  • BMR x 1.2: Little or no exercise.
  • BMR x 1,375: Light exercise (1 to 3 days a week)
  • BMR x 1.55: Moderate exercise (3 to 5 days a week)
  • BMR x 1.72: Athlete (6 -7 days a week)
  • BMR x 1.9: Athlete (morning and afternoon training)
