Livingston and Kohlstadt reported equations for predicting resting metabolic rate (RMR) for normal-sized and obese adults. The autors are from the VA North Texas, the University of Texas Southwestern, and the Florida Orthopedic Institute.
Patient selection: normal-sized and obese adults
Parameters:
(1) gender
(2) age in years
(3) weight in kilograms
RMR in kilocalories per 24 hours for a female =
= 196 * ((weight)^0.4613)
= (248 * ((weight)^0.4356)) - (5.09 * (age))
RMR in kilocalories per 24 hours for a male =
= 246 * ((weight)^0.4473)
= (293 * ((weight)^0.4330)) - (5.92 * (age))
RMR in kilocalories per 24 hours without gender specified =
= 202 * ((weight)^0.4722)
= (261 * ((weight)^0.4456)) - (6.52 * (age))
The equations based on weight and age tended to have the higher R-square values (0.71 for female, 0.77 for male).
