BMR=10 X W + 6.25 X H(cm) – 5.0 X A + sCalories/day*** W=body weight in kg, H=height in cm, A=age in years. This equation considered more accurate than the revised Harris-Benedict equation. JEOR EQUATION :It is the best prediction equation to estimate BMR.
In our BMR calculation used revised Harris-Benedict equation.For Men- BMR=13.397 X W + 4.799 X H(cm) – 5.677 X A + 88.362Calories/dayFor Women- BMR=9.247 X W + 3.098 X H(cm) – 4.330 X A + 447.593Calories/day*** W=body weight in kg, H=height in cm, A=age in years. The revised Harris-Benedict equation published in 1984. The calculation methods for men and women are different, mainly due to differences in body mass or weight. HARRIS – BENEDICT EQUATION :This is the most widely used equation to calculate BMR published in 1919. Some of the well known and used equations as follows: There are various methods to estimate BMR. On that base, we can correct our intake and maintain our weight and health. But we can calculate the approximate value of it. The exact calculation of the BMR of an individual is not possible. That if you rest on the bed and do nothing, then the amount of energy need to maintain your body activity is BMR. We consume energy for the vital function of our body, Physical Activity, and thematic effect of food.īasal Metabolic Rate or Body Metabolic Rate is that how much energy expand to maintain a vital function of your body an activity like blinking, heart pumping, blood circulating, etc. To understand BMR we need to understand the TDEE (Total Daily Energy Expenditure) of our body.
#Schofield bmr calculator update
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.BMR- Basal Metabolic Rate. As muscle and fat require differing amounts of calories to maintain, the TEE estimates will not be accurate for such cases.
Later work produced BMR estimators that accounted for lean body mass.Īs 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. published an equation more predictive for modern lifestyles in 1990. 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 equations revised by Mifflin and St Jeor in 1990: MenīMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5īMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161 The 95% confidence range for men is ☒13.0 kcal/day, and ☒01.0 kcal/day for women. The Harris–Benedict equations revised by Roza and Shizgal in 1984. The original Harris–Benedict equations published in 19.
