# Basal metabolic rate (BMR) calculator

Basal metabolic rate (BMR) is the amount of energy (measured in calories) that the body burns at rest to maintain basic bodily functions such as breathing, maintaining body temperature, and the beating of the heart. It represents the minimum amount of energy required by the body to sustain life and is influenced by factors such as age, sex, weight, and muscle mass. Knowing one’s BMR can be helpful in determining how many calories you should consume in a day to maintain or lose weight.

## How do I calculate my basal metabolic rate (BMR)?

This calculator uses the The Mifflin St. Jeor equation. The formula is as follows:

- For Men: BMR = 10 x weight (kg) + 6.25 x height (cm) - 5 x age (y) + 5
- For Women: BMR = 10 x weight (kg) + 6.25 x height (cm) - 5 x age (y) - 161
