This Calculator Calculates the requirement of calorie/day on the basis of Harris Bendict Equation.Which is most accurate formula yet discovered to calculate the daily calories requirements of a human body.

What is Harris Bendict 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). The only factor omitted by the Harris Benedict Equation is lean body mass. Remember, leaner bodies need more calories than less leaner ones. Therefore, this equation will be very accurate in all but the very muscular (will under-estimate calorie needs) and the very fat (will over-estimate calorie needs).

What is BMR Forlmula?

The BMR formula uses the variables of height, weight, age and gender to calculate the Basal Metabolic Rate (BMR). This is more accurate than calculating calorie needs based on body weight alone. The only factor it omits is lean body mass and thus the ratio of muscle-to-fat a body has. Remember, leaner bodies need more calories than less leaner ones. Therefore, this equation will be very accurate in all but the very muscular (will underestimate calorie needs) and the very fat (will over-estimate calorie needs).

Note:The requirement of the calories in the body of a women may vary according to his condition. Like , expactant Mother Needs 300 calories extra per day. And a lactating mother needs 550 calorie extra per day.
