What is the formula for calculating REE?
Simplification of this formula and separation by sex did not affect its predictive value: REE (males) = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) + 5; REE (females) = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) – 161.
Is the Harris-Benedict formula accurate?
Of the predictive equations tested, the Harris-Benedict equation (mean difference: -14.8 kcal/day, RMSPE: 195.8 kcal/day, mean % difference: 0.1%) was the most accurate and precise, but accuracy in prediction of the equation were only 35.7%.
Which BMR equation is most accurate?
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.
How do you remember the Harris-Benedict equation?
How do I calculate my BMR?
- For women, it’s: BMR = 655.1 + (9.563 * weight in kg) + (1.850 * height in cm) – (4.676 * age) .
- For men, the formula is: BMR = 66.5 + (13.75 * weight in kg) + (5.003 * height in cm) – (6.75 * age) .
What does REE stand for nutrition?
1. Resting Energy Expenditure (REE): the amount of calories needed to maintain basic body systems and body temperature at rest. 2. Activity Energy Expenditure (AEE): the amount of calories used during activity.
How do you calculate your BMR NHS?
BMR formula There are 2 formulae used to calculate BMR, in [kcal / 24hrs] for men and women respectively: BMR for Men = 66.47 + (13.75 * weight [kg]) + (5.003 * size [cm]) − (6.755 * age [years]) BMR for Women = 655.1 + (9.563 * weight [kg]) + (1.85 * size [cm]) − (4.676 * age [years])
What is the importance of using the Harris Benedict formula?
The Harris Benedict equation is a calorie formula using the variables of height, weight, age, and gender to calculate basal metabolic rate (BMR). This is more accurate than calculating calorie needs based on total body weight alone.
What is the difference between BMR and REE?
Basal metabolic rate vs. 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.
Are RMR and BMR the same?
The terms RMR (Resting Metabolic Rate) and BMR (Basal Metabolic Rate) are often used interchangeably.
What weight is used in Harris Benedict equation?
In men, the Harris-Benedict equation formula used was: BMR=66.4730 + 13.7516 x weight in kg + 5.0033 x height in cm – 6.7550 x age in years. In women, BMR=655.0955 + 9.5634 x weight in kg + 1.8496 x height in cm – 4.6756 x age in years….
| Correlation Coefficient (r) | |
|---|---|
| Age | -0.107 |
| Male sex | 0.538 |
| Height | 0.578 |
| Weight | 0.762 |
How do I calculate my BMI and BMR?
BMI and BMR Formulas How to calculate BMI is rather simple. BMR is measured in kJ and BMI is measured by dividing mass/height that is kg/m2 as a unit of measurement. BMR formula is based on the energy units spent so ideally if say, you have to lose 1kg of fat then you need to burn 3500 calories.
