Equation of Johnstone et al for Estimating the Basal Metabolic Rate (BMR) of an Adult

Description

Johnstone et al reported an equation for estimating an adult's basal metabolic rate (BMR). The authors are from Rowett Research Institute and University of Aberdeen in Scotland.

Patient selection: Scottish Caucasian adults with BMI from 16.7 to 49.3 kg per square m

Parameters:

(1) fat-free mass (FFM) in kilograms

(2) fat mass (FM) in kilograms

(3) age in years

fat mass =

= (body weight) - (fat-free mass)

BMR in kiloJoules per day =

= (90.2 * (FFM)) + (31.6 * (FM)) - (12.2 * (age)) + 1613

If the equation for fat mass is substituted:

BMR in kiloJoules per day =

= (58.6 * (FFM)) + (31.6 * (body weight)) - (12.2 * (age)) + 1613
