BMR calculator will calculate your BMR value. Basal metabolic rate (BMR) is the amount of energy per unit time that a person needs to keep the body functioning at rest. Some of those processes are breathing, blood circulation, controlling body temperature, cell growth, brain and nerve function, and contraction of muscles. The basal metabolic rate accounts for about 60 to 75% of the daily calorie expenditure by individuals.
If the body fat percentage is provided, the calculator will use the Katch-McArdle Formula that normally generates better result than all other formula.
If the body fat percentage is not provided, the Mifflin St Jeor formula will be used because it is more accurate than the others.
Basal metabolic rate (BMR) is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions.
You can estimate how many calories you need everyday to maintain your weight based on your activity level:
If you didn't input the body fat percent value, we used
Mifflin-St Jeor Formula: \[ For\ men: BMR = 10Weight + 6.25Height - 5Age + 5 \] \[ For\ women: BMR = 10Weight + 6.25Height - 5Age - 161 \] If you provided the body fat percent value that you can get it either use our body fat percentage calculator or from a device such as a fat percentage scale or caliper, then we will use
Katch-McArdle Formula: \[ BMR = 370 + 21.6(1 - BFP)Weight \]
