The Mifflin-St Jeor formula, created in the 1990s, provided an alternative and more valid estimate of RMR (3). The equations for males and females are: Men: (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) + 5. Women: (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) – 161.
What is the Mifflin St JEOR equation used for?
In our Basal Metabolic Rate Calculator, we use the Mifflin St Jeor Equation to give you the most accurate BMR score.
Is Mifflin St JEOR equation accurate?
Of these equations, the Mifflin-St Jeor equation was the most reliable, predicting RMR within 10% of measured in more nonobese and obese individuals than any other equation, and it also had the narrowest error range.
How do you use Mifflin St JEOR to lose weight?
- Men: (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) + 5.
- Women: (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) – 161.
What is the difference between Harris Benedict and Mifflin St JEOR?
Due to changes in lifestyle, new predictions such as the Mifflin St Jeor equation are more accurate. … Concerning you question, the difference between Harris–Benedict and Mifflin St Jeor equations is around 5 %, with higher accuracy of the later one.
Who is Harris Benedict equation used for?
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 a limitation of the Mifflin St Jeor equation for estimating resting metabolism? It does not account for a person’s body composition.
Which BMR formula is most accurate?
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 I calculate my caloric needs?
- If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2.
- If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375.
The terms RMR (Resting Metabolic Rate) and BMR (Basal Metabolic Rate) are often used interchangeably. … Or put another way, metabolic rate is an estimate of how many calories you would burn if you were to do nothing but rest for 24 hours. It represents the minimum amount of energy required to keep your body functioning.

Among the pre-existing equations, the Schofield equation provided the highest percentage of accurate prediction with 59.1%, 18.7% overprediction, and 22.2% underprediction.
Is Katch McArdle formula accurate?
The Katch–McArdle [38] equation was more accurate in the other two BMI groups, with 37% (25 to <30 kg/m2) and 53.4% (≥30 kg/m2). We have found discrepancies between most of the calculated equations and REEIC in women with normal weight, overweight, and ≥60 years.
Is the Harris-Benedict equation 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%.
What is the revised Harris-Benedict equation?
SexUnitsCalculationWomenMetricBMR = 655 + ( 9.563 × weight in kg ) + ( 1.850 × height in cm ) – ( 4.676 × age in years )
How is Schofield equation calculated?
Age (years)MalesFemales30-59BMR = 11.472 x (wt kg) + 873.1 SEE = 167BMR = 8.126 x (wt kg) + 845.6 SEE = 111
What is a major difference between the Mifflin St JEOR and Katch McArdle equations quizlet?
The Katch-McArdle equation requires data about body composition, whereas Mifflin St Jeor does not. What are carbohydrate guidelines for endurance athletes who partake in very-high-volume, endurance-based training such as athletes engaging in > 6 hours of training per day at 5-7 days per week?
What is TDEE nutrition?
HealthSource. On a quest to shed pounds, there’s a good chance you’ll come across the acronym TDEE, which stands for total daily energy expenditure. In the world of weight-loss, this number may be used to calculate how many calories you need to cut from your daily diet in order to send the scale in a downward direction …
How many calories do I burn resting?
The amount of calories burned increases according to body weight. So, a person who weighs 150 pounds might burn 46 calories an hour or between 322 and 414 calories a night. And a person who weighs 185 pounds might burn around 56 calories or between 392 and 504 calories for a full night of sleep.
What is the WHO equation for energy expenditure?
BMR was first estimated with the following equations: BMR=15.3 × body weight (BW)+679 (for men aged 18–30 y), 11.6 × BW+879 (for men aged 30–60 y), 14.7 × BW+496 (for women aged 18–30 y) and 8.7 × BW+829 (for women aged 30–60 y).
When was the Harris Benedict equation developed?
The most widely used prediction equation is the Harris-Benedict Equation (HBE), which was developed in 1918 as a simple, easy-to-use and universally available method for calculation of BMR.
What is the formula for calculating calories in food?
To calculate this, divide a food or drink’s calories from fat by total calories (this information is on the product’s food label) and then multiply by 100. For example, if a 300-calorie food has 60 calories from fat, divide 60 by 300 and then multiply by 100.
How do you calculate protein intake?
To determine your daily protein intake, you can multiply your weight in pounds by 0.36, or use this online protein calculator. For a 50-year-old woman who weighs 140 pounds woman and who is sedentary (doesn’t exercise), that translates into 53 grams of protein a day.

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.
What is the difference between RMR and TDEE?
Your basal metabolic rate (BMR) or resting metabolic rate (RMR) is the amount of calories your body burns at rest. … Total Daily Energy Expenditures (TDEE) measures the same type of calories as RMR, PLUS the calories your body burns daily while working, playing, or exercising.
Why is RMR important?
Knowing your RMR can help you understand how many calories you need to function, plus what you need to intake (or not intake) to reach your health and wellness goals. Having a higher RMR means you will burn more calories at a state of rest (yep – just for doing nothing more than simply existing!)
Is RMR greater than BMR?
When the results are compared, RMR readings are usually a little higher than BMR readings. However, according to the National Research Council, the difference is almost always less than 10 percent. It is most important to note, however, that most doctors find that your BMR is more accurate than your RMR.
What is basal metabolic weight?
Basal Metabolic Rate is the number of calories required to keep your body functioning at rest. BMR is also known as your body’s metabolism; therefore, any increase to your metabolic weight, such as exercise, will increase your BMR. To get your BMR, simply input your height, gender, age and weight below.
How do you use Katch-McArdle formula?
- For men: LBM = 0.407 * weight [kg] + 0.267 * height [cm] – 19.2.
- For women: LBM = 0.252 * weight [kg] + 0.473 * height [cm] – 48.3.
What is lean mass?
Muscle Mass. Lean Body Mass (also sometimes known as simply “lean mass,” likely the source of the word “lean muscle”) is the total weight of your body minus all the weight due to your fat mass.
