HarrisBenedict Calculator
If you care about your health and weight, the HarrisBenedict calculator (BMR calculator) and the HarrisBenedict equation are the perfect tools for you! In the following article we will explain to you how this simple tool works and how to use it.
What is a BMR calculator?
Basal metabolic rate (BMR) is equivalent to the amount of energy (in the form of calories) that the body needs to function while resting for 24 hours.
How can you calculate your BMR?
Calculating your basal metabolic rate is easy. You will need these two factors: your weight, height and age. You should also take into account your sex. The calculators for both sexes are as follows:

For men: BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) + 5

For women: BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) – 161
What is HarrisBenedict equation?
The Harris Benedict Equation is a formula that uses your BMR and then applies an activity factor to determine your total daily energy expenditure (calories).
How to determine HarrisBenedict equation?
To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows:
 Sedentary (little or no exercise) : CalorieCalculation = BMR x 1.2
 Lightly active (light exercise/sports 13 days/week) : CalorieCalculation = BMR x 1.375
 Moderately active (moderate exercise/sports 35 days/week) : CalorieCalculation = BMR x 1.55
 Very active (hard exercise/sports 67 days a week) : CalorieCalculation = BMR x 1.725
 If you are extra active (very hard exercise/sports & physical job or 2x training) : CalorieCalculation = BMR x 1.9
