Table:  Predictive Equations for Resting Metabolic Rate (RMR) in kcal/day

All equations use weight in kilograms (kg), height in centimeters (cm) except the WHO/FAO/UNU equation that uses height in meters (m).

Mifflin-St Jeor

Men: RMR = 9.99 X weight + 6.25 X height – 4.92 X age + 5

Women: RMR = 9.99 X weight + 6.25 X height – 4.92 X age – 161

Harris Benedict

Men: RMR = 66.47 + 13.75 X weight + 5.0 X height – 6.75 X age

Women: RMR = 655.09 + 9.56 X weight + 1.84 X height – 4.67 X age

Owen

Men: RMR = 879 + 10.2 X weight

Women: RMR = 795 + 7.18 X weight

WHO/FAO/UNU

Weight only:

Age (yr)

Men

18-30 RMR = 15.3 X weight + 679

31-60 RMR = 11.6 X weight + 879

>60 RMR = 13.5 X weight + 487

Women

18-30 RMR = 14.7 X weight + 496

31-60 RMR = 8.7 X weight + 829

>60 RMR = 10.5 X weight + 596

Weight and height (m):

Age (yr)

Men

18-30 RMR = 15.4 X weight – 27 X height + 717

31-60 RMR = 11.3 X weight + 16 X height + 901

>60 RMR = 8.8 X weight + 1128 X height – 1071

Women

18-30 RMR = 13.3 X weight + 334 X height + 35

31-60 RMR = 8.7 X weight – 25 X height + 865

>60 RMR = 9.2 X weight + 637 X height – 302
