The Harris benedict calculator measures the total number of calories in our diet. Harris-Benedict Formula is quite useful for measuring our per-day energy requirements.
The first formula to measure BMR was invented by the Harris-Benedict. The Harris-Benedict formula is based on the variables like height, weight, age, gender, and activity level.
There is a separate Harris-benedict equation for men and women:
| Sex | Units | Calculation |
|---|---|---|
| Men | Metric | BMR = 66.5 + ( 13.76 × weight in kg ) + ( 5.003 × height in cm ) – ( 6.755 × age in years ) |
| Imperial | BMR = 66 + ( 6.2 × weight in pounds ) + ( 12.7 × height in inches ) – ( 6.76 × age in years ) | |
| Women | Metric | BMR = 655 + ( 9.563 × weight in kg ) + ( 1.850 × height in cm ) – ( 4.676 × age in years ) |
| Imperial | BMR = 655 + ( 4.35 × weight in pounds ) + ( 4.7 × height in inches ) – ( 4.7 × age in years ) |
Why Use the Harris-Benedict Equation?
We can measure the accurate level of our Total Daily Energy Expenditure or TDEE requirements by the Harris-benedict equation. When we are measuring the energy requirements, we can ignore various parameters and may ignore the calorie requirements for various age groups. To measure your total daily calorie requirement, you need to multiply your BMR by the appropriate activity level. Â
| Calorie-Calculation | Sedentary | Little or No Exercise | BMR x 1.2 |
|---|---|---|---|
| Calorie-Calculation | Lightly Active | Sports 1-3 Days/Week | BMR x 1.375 |
| Calorie-Calculation | Moderatetely Active | Sports 3-5 Days/Week | BMR x 1.55 |
| Calorie-Calculation | Very Active | Sports 6-7 Days a Week | BMR x 1.725 |
| Calorie-Calculation | Extra Active | Physical Job or 2xTraining | BMR x 1.9 |
When you intend to lose weight then you may need to shed weight at various rates according to your body’s requirement. For various activities level, it is quite convenient to use the Harris Benedict BMR calculator for avoiding any mistakes in determining your BMR level.
Calculate the BMR, TDEE, and Macros requirement of a person. The age of the person is 25 years his height is 5 feet 9 inches, his weight is 158 lbs and he is maintaining a moderate activity level.
Age = 25 years
Gender = Male
Height =Â 5 feet 9 inches
Weight = 158 lbs
Activity level = Moderate
Enter values in the harris-benedict equation for men:
BMR = 66.5 + (13.75 × weight [kg]) + (5.003 × height [cm]) – (6.775 × age [years])
BMR =1760 kcal/day
Total Energy Expenditure =2728 kcal/day
Carbohydrates =375 Grams per day
Protein = 102 Grams per day
Fats = 205 Grams per day
