Knowing how many calories you burn while fasting will help you to lose, gain or sustain your weight. How many calories you burn fasting can also be classified as your basal metabolic rate or resting energy expenditure. This is the amount of calories your body must burn to perform its normal functions.

## Significance

The calories you burn fasting are responsible for the normal functions of your vital organs. This includes keeping your heart beating, your lungs breathing and all other regulatory functions. Although there are a few different equations that can be used to find out how many calories you burn while at rest, the Harris Benedict equation is the most popular.

## Men

To calculate the BMR for men, use the following equation:

(13.75 x weight in kilograms) + (5 x height in centimeters) - (6.76 x age in years) + 66

Remember that weight is in kilograms and height is in centimeters.

## Women

To calculate the BMR for women, use the following equation:

(9.56 x weight in kilograms) + (1.85 x height in centimeters) - (4.68 x age in years) + 655

Remember that weight is in kilograms and height is in centimeters.

## Conversions

To convert pounds into kilograms, divide your weight in pounds by 2.2. To convert your height into centimeters, multiply your height in inches by 2.54.
