How do you calculate BMR using Harris Benedict formula?

How do you calculate BMR using Harris Benedict formula?

To calculate your BMR, you would usually use the Harris-Benedict equation:

  1. For women, it’s: BMR = 655.1 + (9.563 * weight in kg) + (1.850 * height in cm) – (4.676 * age) .
  2. For men, the formula is: BMR = 66.5 + (13.75 * weight in kg) + (5.003 * height in cm) – (6.75 * age) .

How is Harris-Benedict RMR calculated?

Harris and Benedict Equation

  1. Men: 88.362 + (13.397 × weight in kg) + (4.799 × height in cm) – (5.677 × age in years)
  2. Women: 447.593 + (9.247 × weight in kg) + (3.098 × height in cm) – (4.330 × age in years)

How do you calculate your BMR?

Calculate Basal Metabolic Rate Your basal metabolism rate is produced through the following basal metablic rate formula: Men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years) Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)

Why is Harris-Benedict equation used?

The Harris-Benedict equation may be used to assist weight loss — by reducing the kilocalorie intake number below the estimated maintenance intake of the equation.

Is RMR and BMR the same?

Basal metabolic rate (BMR) is often used interchangeably with resting metabolic rate (RMR). While BMR is a minimum number of calories required for basic functions at rest, RMR — also called resting energy expenditure (REE) — is the number of calories that your body burns while it’s at rest.

Which BMR calculator is most accurate?

There are multiple formulas used to calculate BMR. Nowadays, the Mifflin-St Jeor equation is believed to give the most accurate result and, is therefore what we used in this calculator.

What is the most accurate BMR estimation formula?

the Mifflin-St Jeor Equation
Of these equations, the Mifflin-St Jeor Equation is considered the most accurate equation for calculating BMR with the exception that the Katch-McArdle Formula can be more accurate for people who are leaner and know their body fat percentage.

What is the most accurate BMR calculator?

Can you accurately measure BMR?

BMR is most accurately measured in a lab setting under very restrictive conditions. Resting metabolic rate is a measurement of the number of calories that your body burns at rest. Resting metabolic rate is usually measured in the morning before you eat or exercise and after a full night of restful sleep.

Are RMR calculators accurate?

In fact, many online RMR calculators have been shown to have a variance of +/- 300 calories, equivalent to a small meal each day, which can drastically affect results over time. Since accuracy is particularly important for setting goals around nutrition, it’s crucial to turn to a professional source for RMR testing.

What is the difference between Harris-Benedict and Mifflin-St JEOR?

Both the Harris-Benedict formula and Mifflin – St Jeor formula are commonly used and referenced today. It has been suggested that the difference between the Harris-Benedict and Mifflin-St Jeor equations is around 5%, with a higher accuracy level achieved by the Mifflin – St Jeor formula.

Should you eat below your BMR?

Should you eat less than your BMR to lose weight? Since BMR represents the minimal calorie number you need for involuntary body functions, you shouldn’t consume fewer calories than your BMR. To lose weight properly, you need to consider both physical activity and your BMR.

Are BMR calculators accurate?

Therefore, all BMR calculations, even using the most precise methods through specialists, will not be perfectly accurate in their measurements. Not all human bodily functions are well understood just yet, so calculating total daily energy expenditure (TDEE) derived from BMR estimates are just that, estimates.

What is a normal BMR for a woman?

Maintaining lean muscle mass also helps reduce the chance of injury when training, and exercise increases your daily energy expenditure. An average man has a BMR of around 7,100 kJ per day, while an average woman has a BMR of around 5,900 kJ per day.
