Notes
  • The default unit of measure for weight is kilograms. Please verify that the correct unit of measure has been selected.
  • This is an approximation of BEE.
  • Expect 20 to 30% variability between individuals.
  • HBE is the most widely used formula for estimating BMR and caloric requirements in adult surgical patients. Other predictive equations may be appropriate in specific surgical populations (eg, bariatric, severe burn injury) or other medical populations (eg, pediatric, critically ill). For additional information, including the accuracy of HBE relative to the REE as measured by IDC, refer to UpToDate topics on nutrition support.
  • BEE: basal energy expenditure; HBE: Harris-Benedict equation; BMR: basal metabolic rate; ICU: intensive care unit; REE: resting energy expenditure; IDC: indirect calorimetry.

 
Equations used
 
BEE_females = 655.1 + (9.563 * Weight) + (1.85 * Height) - (4.676 * Age)
BEE_males = 66.5 + (13.75 * Weight) + (5.003 * Height) - (6.775 * Age)

 

 
Only digits 0 to 9 and a single decimal point (".") are acceptable as numeric inputs. Attempted input of other characters into a numeric field may lead to an incorrect result.
