However, it provides a good beginning for understanding your calorie needs. = 66.5 + (13.75 x kg) + (5.003 x cm) - (6.775 x age) For women, B.E.E. The Harris Benedict equations (HBE) were derived from indirect calorimetric data obtained in 239 normal subjects. The Harris-Benedict formula, or Harris-Benedict equation, lets you work out how many calories you need to eat per day. Equation to Calculate Your BMR The Harris-Benedict Equation is often used to estimate basal metabolic rate. This newer equation may have greater accuracy in obese patients. For Women: BMR = (9.5634 x weight + 1.8496 x height – 4.6756 x age + 655.0955) kcal/day With these factors, the Harris-Benedict Calorie Calculator is able to calculate the basal metabolic rate (BMR) which is the amount of energy you will need for your body to function correctly. The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR) and daily kilocalorie requirements.The estimated BMR value is multiplied by a number that corresponds to the individual's activity level. To calculate the number of calories you burn in a day while at rest, you can work out the Harris Benedict formula or The Mufflin equation for your own height, weight. The Harris Benedict Calculation is a formula that uses your BMR and then applies an activity factor to determine your total daily energy expenditure (calories). The Harris–Benedict equations revised by Mifflin and St Jeor in 1990:[4]. The Harris Benedict Equation is a formula that was created from and by the research of James Arthur Harris and Francis Gano Benedict in 1919. Remember, leaner bodies need more calories than less leaner ones. [citation needed], The original Harris–Benedict equations published in 1918 and 1919. Variance:The resting and basal … Your BMR is a sum of your age, weight, and height, which can be calculated with the Harris-Benedict formula: For Men: BMR = 66 + (13.7 x weight in kg) + (5 x height in cm) - (6.8 x age) For Women: BMR = 655 + (9.6 x weight in kg) + (1.7 x height in cm) - (4.7 x age) Step #2: Daily Physical Activity Level For men, B.E.E. To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows: For more on BMR, check out the Mifflin St Jeor equation and the Katch-McArdle formula. The Harris-Benedict equation is a formula commonly used to estimate basal energy expenditure of individuals, adjusted for height, weight, age and gender. *Basal Metabolic Rate is calculated by the Harris-Benedict equation (created in 1919, but still applicable today). Basal Metabolic Rate (BMR) Basal metabolic rate (BMR) is the amount of energy required tomaintain the body's normal metabolic activity, such as respiration,maintenance of body temperature (thermogenesis), and digestion.Specifically, it is the amount of energy required at rest with noadditional activity. The Harris-Benedict equations remain the most common method for calculating BEE for clinical and research purposes. Quick Reference. The Harris-Benedict Calorie Calculator bases its recommended Daily Calorie Intake on a variety of different parameters depending on factors such as: gender, height, weight, age and physical activity. In the following article we will explain to you how this simple tool works and how you can use it to your advantage. We can estimate the value of BMR/RMR using a same formula. The widespread use of the equations and the relative inaccessibility of the original work highlights the importance of reviewing the data from which the standards were developed. Researchers have developed several equations that predict basal metabolic rate. In each of the formulas below: P is total heat production at complete rest, m is mass (kg), h is height (cm), and; a is age (years), The original Harris-Benedict equation So, if you create a 3500-calorie deficit through diet, exercise or … 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) Knowing how many calories someone burns in a day can be very helpful if that person is trying to gain or lose weight. The Harris–Benedict equation may be used to assist weight loss — by reducing kilocalorie intake number below the estimated maintenance intake of the equation. 655.1 + (9.563 x kg) + (1.850 x cm) - (4.676 x age) Stress Factors ( ) Infection, mild (10%) Infection, moderate (25%) Infection, severe (45%) Harris Benedict Equations: BMR calculation for men (metric) BMR = 66.47 + ( 13.75 x weight in kg ) + ( 5.003 x height in cm ) - ( 6.755 x age in years ) BMR calculation for women (metric) BMR = 655.1 + ( 9.563 x weight in kg ) + ( 1.850 x height in cm ) - ( 4.676 x age in years ) BEE Formula English Units. The ACE provide two equations that people can use to calculate their RMR: the Revised Harris-Benedict BMR equation, and the Mifflin-St Jeor equation.

The only factor omitted by the Harris Benedict Equation is lean body mass. Calculating your basal metabolic rate is easy; all you need to measure is your weight and height, although your age and sex also come into play. The metabolic rate can be measured or estimated by equations, but estimation is by far the most common method. The Harris–Benedict equation sprang from a study by James Arthur Harris and Francis Gano Benedict, which was published in 1919 by the Carnegie Institution of Washington in the monograph A Biometric Study Of Basal Metabolism In Man. The Harris-Benedict formula is used to describe your basal metabolic rate (BMR) as a numeric value. If you are looking to gain or lose weight, you can also use this number as a point to eat more or less then, respectively. The Mifflin-St Jeor Equation has been shown to be more accurate than the revised Harris-Benedict Equation. The paper behind the latest update (Mifflin et al) to the BMR formula states all participants in their study fall within the 'normal' and 'overweight' body mass index (BMI) categories, and so the results also do not necessarily apply to those in the 'underweight' or 'obese' BMI categories. Harris-Benedict Equation The original Harris-Benedict equation was created in 1919 following a study by James Arthur Harris and Francis Gano Benedict.

This estimate is then multiplied by a physical activity factor to estimate total daily energy needs to maintain the given weight. The BMR formula uses the variables of height, weight, age and gender to calculate the Basal Metabolic Rate (BMR). Everybody requires a minimum number of calories to live. Using the Harris-Benedict equation to calculate Jane’s BMR indicates her BMR is ~1630 kcal/day. Our apologies for the inconvenience it has caused. Calorie Needs to lose weight There are approximately 3500 calories in a pound of stored body fat. Due to lack of availability in many institutions, predictive equations are used to estimate energy requirements. Stress plus activity factors range from 1.2 to over 2. Harris-Benedict equation: ( har'is-ben'ĕ-dikt ē-kwā'zhŭn ) An equation based on a person's height, age, and weight that is used for estimating caloric needs. It refers to the amount of energy that the body requires to manage and maintain the normal metabolic activity of the body. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight. (Revised) Harris Benedict Equations: Note: The original Harris Benedict equation was revised in 1984. BEE value varies with the gender and age. How to determine the Harris-Benedict equation? As the BMR equations do not attempt to take into account body composition, identical results can be calculated for a very muscular person, and an overweight person, who are both the same height, weight, age and gender. Next Steps. The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR). The Harris-Benedict equationis often used to estimate your calorie needs. W = weight in kilograms H = … So we've decided to remove it. Published in 1919 (J. Arthur Harris & Francis G. Benedict) Predominantly “normal” weight healthy white subjects (Boston) (N =239) 136 men aged 16-63 years (13 underweight) 103 women aged 15-74 years (21 underweight) RMR is the amount of calories that is burned while in complete rest. Mifflin et al. To determine daily calorie requirements, the value of Basal Metabolic Rate is multiplied by a factor that reflects the activity level of an individual. Sedentary (little to no exercise) Light exercise (1-3 days per week) Moderate exercise (3–5 days per week) Heavy exercise (6–7 days per week) Very heavy exercise (twice per day, extra heavy workouts) Result: Please fill out required fields. They each have specific indications. This estimate is then multiplied by a physical activity factor to estimate total daily energy needs to maintain the given weight. = 655.1 + (9.563 x kg) + (1.850 x cm) - (4.676 x age) Total Caloric Requirements equal the B.E.E. WHAT IS BASAL METABOLIC RATE (BMR)? = 1 kg). Aim: This study tests the degree of agreement between measured resting energy expenditure by indirect calorimetry and predicted resting energy expenditure by Harris Benedict and Mifflin-St Jeor equations. Mifflin St. Jeor derived a formula to find the resting metabolic rate. Therefore, this equation will be very accurate in all but the very muscular (will under-estimate calorie … The Harris Benedict Equation is a formula that uses your BMR and then applies an activity factor. The Harris-Benedict formula, or Harris-Benedict equation, lets you work out how many calories you need to eat per day. Formulas: Men. Harris-Benedict Equation was proposed by J. As an alternative method of calculation, the Harris Benedict equations adopt separate equations for men and women as follows: For Men: BMR = (13.7516 x weight + 5.0033 x height – 6.755 x age + 66.473) kcal/day. The Harris-Benedict formula is often used to assist weight loss by ensuring that you reduce the intake of calories below what you need to maintain weight. The Harris-Benedict Equation was one of the earliest equations introduced. A equação de Harris-Benedict (também chamada de princípio de Harris-Benedict) é um método usado para estimar a taxa metabólica basal (TMB) de um indivíduo .. O valor de BMR estimado pode ser multiplicado por um número que corresponde ao nível de atividade do indivíduo; o número resultante é a ingestão diária aproximada de quilocalorias para manter o peso corporal atual . The four most famous equations for the estimation of metabolic requirements are the Harris-Benedict, Ireton-Jones, Fusco and Frankenfield equations. One of the more common equations in the Harris-Benedict Equation. Our maintenance calorie calculator uses the Mifflin-St Jeor formula, as this is one of the most popular BMR equations and is recommended by the US Academy of Nutrition and Dietetics. Harris Benedict Equation Calculator. For the same 150-pound woman, the BMR using the Harris Benedict equation would be: BMR= 655.1 + (9.563 x 68) + (1.850 x 163) - ( 4.676 x 25) = … published an equation more predictive for modern lifestyles in 1990. Formulas: Men. Though it has been modified and changed over the years, it’s still the most widely used equation today that uses your Basal Metabolic Rate (BMR) in combination with your activity level to determine your total daily energy usage in calories. The Harris and Benedict (H&B) equation created in 1918 and amended in 1984 remains widely used today (1-2).. RMR is also known as BMR (basal metabolic rate). A Harris – Benedict-egyenlet (más néven Harris-Benedict-elv) egy módszer, amelyet az egyén bazális metabolikus sebességének (BMR) becslésére használnak .. A becsült BMR-érték megszorozható egy számmal, amely megfelel az egyén aktivitási szintjének; az így kapott szám a hozzávetőleges napi kilokalória-bevitel az aktuális testtömeg fenntartása érdekében . Age, gender, height, and weight are needed for this equation. Now you’ve calculated your BMR using one of the above formulae, you can calculate your total daily energy expenditure (TDEE) in the following section. As muscle and fat require differing amounts of calories to maintain, the TEE estimates will not be accurate for such cases. Harris J, Benedict F. A biometric study of basal metabolism in man. [1][2], The Harris–Benedict equations revised by Roza and Shizgal in 1984.[3]. Harris –Benedict Equation Background Developed between 1909 and 1917 and based on indirect calorimetry. This minimum number is called the basal metabolic rate (BMR). 66.5 + (13.75 X weight in kg) + (5.003 X height in cm) – (6.775 X age in years) Women. Harris –Benedict Equation Background Developed between 1909 and 1917 and based on indirect calorimetry. An equation that uses basal metabolic rate and an activity factor to determine (approximately) total daily energy expenditure in calories. A. Harris and F. G. Benedict in the book "A Biometric Study of Basal Metabolism in Man" published in 1919. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight .
