Basal Metabolic Rate (BMR):-   BMR is the amount of energy per unit of time that a person needs to keep the body functioning at rest.   BMR is calculated by three different equations:- (i) Katch McArdle formula:- BMR Kcal/Day = 370 + 21.6 x Lean Body Mass ( kg) LBM= Wt(kg) x ((100-Bodyfat%/100) Or,  LBM for Male:-  0.407x wt (kg) +0.267 x height (cm) -19.2 LBM for Female:- 0.252 x wt (kg) + 0.473 x height (cm)- 48.3 (ii) Miffin St. Jeon equation:- BMR Kcal/day = {10 x body wt. (kg)} + { 6.25 x height ( cm) - 5 x age ( yr) + s* Kcal / day         Where, s*= +5 for male and -161 for female. (iii) Harris Benedict's Equation(1919):- It is the oldest method.
