Equations of Owen et al for Predicting the Resting Metabolic Rate (RMR) in Adult Men and Women

Body Weight Equations

resting metabolic rate for men in kcal/day =

= 879 + (10.2 * (body weight in kilograms))

resting metabolic rate for non-athletic women in kcal/day =

= 795 + (7.18 * (body weight in kilograms))

resting metabolic rate for athletic women in kcal/day =

= 50.4 + (21.1 * (body weight in kilograms))

Fat Free Mass Equations

resting metabolic rate for men in kcal/day =

= 290 + (22.3 * (fat free mass in kilograms))

resting metabolic rate for women in kcal/day =

= 334 + (19.7 * (fat free mass in kilograms))

where:

• Fat free mass is obtained from densitometry measurements.
