Abstract

Basal metabolism is determined by obtaining an age of a subject; determining fat-free mass of the subject; and calculating the basal metabolism of the subject using the determined fat-free mass and a reciprocal of the age. The basal metabolism can be calculated using the formula represented by BMR=A×FFM+B×(1/age)+C, in which BMR is basal metabolism (kcal/day), FFM is fat-free mass (kg), and A, B, and C are constants.
