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

Purpose: To use the equations of Owen et al to predict the resting metabolic rate for an adult man or woman.

Description

Owen et al developed equations to predict the resting metabolic rate for adult (age >= 18 years) men and women. The subjects were healthy and included both lean and obese persons. They found that some equations in use overestimate the resting metabolic rate for adults (in women 7-14%).


 

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.
