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 calorie requirements. The estimated BMR value is multiplied by a number that corresponds to the individuals's activity level. The resulting number is the recommended daily calorie intake to maintain current body weight. The equation assumes a normal body composition, with an average ratio of muscle mass to fat mass, so it may be inaccurate for individuals who are very muscular (the formula underestimates true requirements) or for individuals who are very fat (the equation overestimates true requirements).
The Harris-Benedict equation may be used to assist weight loss — by reducing the calorie intake to a number below the estimated maintenance intake of the equation.

The original Harris-Benedict equations published in 1918 and 1919.[1][2]
| Men |
BMR = 66.4730 + (13.7516 x weight in kg) + (5.0033 x height in cm) – (6.7550 x age in years) |
| Women |
BMR = 655.0955 + (9.5634 x weight in kg) + (1.8496 x height in cm) – (4.6756 x age in years) |
§
The Harris-Benedict equations revised by Roza and Shizgal in 1984.[3]
| 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) |
Step 2 – applying the Harris-Benedict Principle
The following table enables calculation of an individual's recommended daily calorie intake to maintain current weight.[4]
| Little to no exercise |
Daily kilocalories needed = BMR x 1.2 |
| Light exercise (1–3 days per week) |
Daily kilocalories needed = BMR x 1.375 |
| Moderate exercise (3–5 days per week) |
Daily kilocalories needed = BMR x 1.55 |
| Heavy exercise (6–7 days per week) |
Daily kilocalories needed = BMR x 1.725 |
| Very heavy exercise (twice per day, extra heavy workouts) |
Daily kilocalories needed = BMR x 1.9 |
Applications for weight loss
Using the formulae above, a 24-year-old, 80 kg male who is 180 cm would have a BMR of 1900. If he exercised moderately, he would multiply his BMR by his activity level (1900 x 1.55) to determine daily calorie requirements, which would be 2945 kcal per day to keep his weight at 80 kg. This may seem like a high calorie intake, but his activity level requires it. This individual would exercise normally but not lose weight. The same individual without the exercise routine would only be able to consume 2273 kcal per day without gaining weight. The US Department of Health and Human Services Daily Value Guidelines provides figures that support the above example.[5]
Using the Harris-Benedict Equation, individuals can take a mathematical approach to weight loss. There are 3500 kilocalories in 1 lb (0.45 kg) of body fat. Using the Harris-Benedict Principle, if someone has a daily allowance of 2500 kilocalories, but he reduces his intake to 2000, then the calculations show a one pound loss every 7 days.
History
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”.

- Triiodothyronine (T3) and metabolic rate in adolescents with eating disorders: is there a correlation?
- Aschettino-Manevitz DL, Ornstein RM, Meyer Sterling W, Kohn N, Fisher M.AbstractPurpose: To examine the correlation between T3 and resting energy expenditure(REE) in adolescent patients with eating disorders (ED) to assess whether T3 can be used to predict metabolic rate suppression and recovery. Methods: A retrospective chart review was performed on patients with ED (Anorexia Nervosa [AN], Bulimia Nervosa [BN], and Eating Disorder NOS [EDNOS]), aged 11-22 years, who had T3 and REE measured within 1 month (n=38 AN, 32 BN/EDNOS). REE was measured by indirect calorimetry (IC) and represented as the percentage of expected REE (%EREE) predicted by the Harris-Benedict equation. Pearson correlation coefficients were calculated to examine the relationship between T3 and %EREE and how each correlates with anthropometric data, laboratory values, and diagnosis. Results: T3 was significantly correlated with %EREE in the AN group but not in the total population or BN/EDNOS group. In the total study population, T3 alone correlated significantly with weight, Body Mass Index (BMI), BMI percentile, %Ideal Body Weight (IBW), %Maximum Weight Lost (MWL), LH, and estradiol. In the AN group, T3 and %EREE both correlated with BMI, BMI percentile, LH, and estradiol; however, only T3 correlated with %IBW and %MWL. In the BN/EDNOS group, T3 correlated with BMI, BMI percentile, %IBW, and estradiol while %EREE correlated with none. Conclusion: In patients with AN, T3 correlated significantly with markers of malnutrition and %EREE and may serve as a surrogate measure when IC is unavailable. Following T3 during treatment of AN may assist clinicians in assessing metabolic suppression and recovery and help guide caloric prescriptions and goal weights.
