Muller et al developed a number of equations for estimating the resting energy expenditure (REE) of adults. The authors are from multiple institutions in Germany.
Patient selection: adults >=18 years
Parameters:
(1) age in years
(2) gender (0 if female, 1 if male)
(3) height in centimeters
(4) body weight in kilograms
(5) fat-free mass (FFM) in kilograms
(6) fat mass (FM) in kilograms
(7) BMI
REE in megaJoules per day =
= (A * (weight in kilograms)) + (B * (height in cm)) + (C * (points for gender)) + (D * (age)) + E
REE in megaJoules per day =
= (F * (fat free mass in kilograms)) + (G * (fat mass)) + (H * (points for gender)) + (I*(age)) + J
