Which BMR formula is most accurate?
the Mifflin-St Jeor equation
Nowadays, the Mifflin-St Jeor equation is believed to give the most accurate result and, is therefore what we used in this calculator. This BMR formula is as follows: BMR (kcal / day) = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (y) + s (kcal / day) , where s is +5 for males and -161 for females.
What is Mifflin St JEOR equation used for?
The Mifflin-St Jeor Equation is now believed to give the most accurate TDEE result and, is therefore what we used in this calculator. This BMR formula is as follows: BMR (kcal / day) = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (y) + s (kcal / day) , where s is +5 for males and -161 for females.
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%.
What is wrong with the Harris Benedict equation?
The Harris Benedict Formula shows how to calculate BMR, but this is only an estimate based on age, height and weight. The problem is that the Harris Benedict Calculator doesn’t factor in variables such as: Thyroid issues, which can reduce metabolism. Certain hormones can increase or decrease metabolism.
Is Katch-McArdle most accurate?
For this reason, we strongly recommend using the Katch-McArdle formula to calculate your BMR. This formula takes body fat into account properly, and is therefore the most accurate when used correctly.
What calorie formula is the most accurate?
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 Mifflin St JEOR?
The Mifflin-St Jeor equation is one of the most widely used BMR formulas. It appears to provide a closer estimate of true BMR than the Harris-Benedict equation. Studies have found that it is more likely than other equations to estimate basal metabolic rate to within 10% of that measured by indirect calorimetry.
What does Mifflin St JEOR measure?
The Mifflin-St Jeor equation had the lowest value of bias index which provides a mean measure of the overestimation or the underestimation of the specific equation compared to the measured REE (−25.80 kcal/day). These results fitted with the other agreement measures (accuracy, CCC and MSD), as reported in Table
Which calorie equation is the best?
To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows: Sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2. Lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375.
How was the Harris-Benedict equation developed?
The BMR was determined using three methods. 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.
How can the Harris-Benedict equation be improved?
Greater lean body mass = Greater BMR or RMR. Because individuals can increase their total lean body mass through strength training (corresponding increase in skeletal muscle), it is possible to increase the overall basal energy requirements at rest.
Which calorie formula is most accurate?
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.
