Calculator Description

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.

What is the BMR and How to Use it?

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:

• Little or no exercise: BMR x 1.2
• Light exercise: BMR x 1.375
• Moderate exercise: BMR x 1.4625
• Active exercise: BMR x 1.55
• Very active exercise: BMR x 1.725
• Extreamly active exercise: BMR x 1.9
You can also use the Energy Calculator to calculate your daily calories needed to maintain your current weight. The energy calculator take your age and gender into consideration and is based on the Dietary reference intakes (DRI) report from the food and nutrition board, institue of medicine of the national academies. Therefore, the result from energy calculator is generally better than this one.

How to Calaulte the BMR

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: $BMR = 370 + 21.6(1 - BFP)Weight$
