Lazzer et al reported equations for estimating the resting energy expenditure (REE) of obese Italian females. The authors are from the Italian Institute for Auxology, IRCCS, in Milan.
Patient selection: adult Italian female, 19 to 60 years of age, severely obese
Parameters:
(1) body weight in kilograms
(2) fat-free mass (FFM) in kilograms
(3) fat mass (FM) in kilograms
(4) height in meters
fat mass =
= (body weight) - (FFM)
resting energy expenditure in megaJoules per day =
= (0.042 * (weight in kilograms)) + (3.619 * (height in meters)) - 2.678
resting energy expenditure in megaJoules per day =
= (0.067 * (FFM in kilograms)) + (0.046 * (FM in kilograms)) + 1.568
