Table 1 Equations used for the estimation of resting energy expenditure in kcal/d.

From: Predictive equations over-estimate the resting energy expenditure in amyotrophic lateral sclerosis patients who are dependent on invasive ventilation support

Name of the equation Equation
Harris-Benedict [24]  
   Men 66.47 + 13.75 × weight + 5.0 × height - 6.75 × age
   Women 655.09 + 9.56 × weight + 1.84 × height - 4.67 × age
WHO/FAO/UNU [25]  
   Men  
   18 - 30 yrs 15.4 × weight - 27 × height + 717
   31 - 60 yrs 11.3 × weight + 16 × height + 901
   > 60 yrs 8.8 × weight + 1128 × height - 1071
   Women  
   18 - 30 yrs 13.3 × weight + 334 × height + 35
   31 - 60 yrs 8.7 × weight - 25 × height + 865
   > 60 yrs 9.2 × weight + 637 × height - 302
Mifflin-St Jeor [28]  
   Men 9.99 × weight + 6.25 × height -4.92 × age + 5
   Women 9.99 × weight + 6.25 × height -4.92 × age - 161
Owen [26, 27]  
   Men 879 + 10.2 × weight
   Women 795 + 7.18 × weight
Fleisch [29]  
   Men 24 × BSA¹ × (38 - 0.073 × (age - 20))
   Women 24 × BSA¹ × (35.5 - 0.064 × (age - 20))
  1. ¹BSA = body surface area in m² is calculated according to DuBois & DuBois equation [41].
  2. The weight should be given in kilograms and the height in centimetres in all equations.
