EER = 354 - (6.91 X AGE) + PA X (9.36 x WT + 726 x HT)

PA = 1.2

Age = 23 yrs

Height (HT) = 5ft 4' = (5x12) = 60' + 4' = 64' x 1/39.37 = 1.63m

Weight (WT)= 130lbs = 130 x 1/2.2 = 59kg

Lifestyle = Sedentary = 1.00

EER = 354 - (6.91 x 23) + 1.2 x (9.36 x 59 + 726 x 1.63)

=354 - 158.93 + 1.2 (552.24 + 1183.38)

= 195.07 + 2082.744

EER = 2277.8

BMR = 655 + (4.35 x WT LBS) + (4.7 x HT' ) - (4.7 x AGE)

BMR = 655 + (4.35 x 130) + ( 4.7 x 64) - (4.7 x 23)

= 655 + 565.5 + 300.8 - 108.1

BMR = 1413.2

BMR x PA Estimates = 1413.2 x 1.2 = 1695.84 = ~ 1696 Calories daily
