Total Daily Energy Expenditure (TDEE) = BMR X Activity level Jeor Equation.īMR = (Height in centimeters x 6.25) + (Weight in kg x 9.99) – (Age x 4.92) + 5. Jeor EquationĪccording to the American Dietetic Association, the most reliable formula for calculating TDEE is the Mifflin-St. All you have to do to determine your TDEE is multiply your BMR by your level of activity. The BMR is the number of calories you need to perform metabolic activities like respiration, digestion, and circulation. When calculating your TDEE, you first have to know your basal metabolic rate (BMR), level of activity, and daily food intake. We also have a BMR calculator right here.īut for those of you who want to know how the math works… read on! You can calculate your Total Daily Energy Expenditure using different formulas, but almost all of them are confusing and inaccurate.
If you want to do it the easy way, use our TDEE calculator right here.

The challenge is how to calculate that number. But if you are okay with your current body, all you have to do is calculate your TDEE and keep your calorie intake close to that figure. Olympia, you need to eat above your TDEE so your body can get the nutrients it needs to make you bigger and stronger. And if you are training to be the next Mr. If you are trying to gain muscle mass, lose weight, or maintain your current body weight, it’s important that you understand the effect of Total Daily Energy Expenditure on your goal and how to calculate it.įor somebody aiming to lose some pounds, your target is to make your calorie intake less than calorie burn, i.e., eat below your TDEE. TDEE is an essential factor if you are trying to lose weight or gain weight because the two are basically about the deficit between your calorie intake and calorie expenditure.īecause every individual has a unique set of genes, in addition to gender, age, and weight, we all have distinct TDEEs. It represents an estimated total of the calories your body burns for energy each day. Limits of agreements were wide for both equations in all cases and each category so clinical significance was considerable.Īt a group level Harris-Benedict equation is suitable for predicting REE but at an individual level, both equations have wide limits of agreement and clinically important differences in REE would be obtained.TDEE is an acronym for Total Daily Energy Expenditure. The only statistically significant difference was seen between measured resting energy expenditure and its predicted equivalent by Mifflin-St equation when patients were categorized according to their sex. There was no statistically significant difference between measured and predicted resting energy expenditure by both equations, in all cases as a whole and each group. Statistical analysis was performed by using the method of Bland-Altman, one sample t-test and Pearson's correlation. In 60 randomly selected patients, aged between 18 and 83 years, resting energy expenditure (REE) was measured by indirect calorimetry and compared with the predicted equations of Harris Benedict and Mifflin-St Jeor. Patients were categorized according to sex and diagnosis. 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. The metabolic rate can be measured or estimated by equations, but estimation is by far the most common method. An understanding of energy expenditure in hospitalized patients is necessary to determine optimal energy supply.
