BMR calculation

Basal metabolism is the amount of energy spent daily by humans and other animals at rest, doing nothing, to perform a set of functions necessary for life such as cell metabolism, synthesis and metabolism of enzymes and hormones, transport of substances around the body, maintenance of body temperature and ongoing functioning of muscles including the heart, and brain function.

The BMR Formula in our calculation is based on the The Mifflin St Jeor Equation:
BMR = (10m/1kg + 6.25h/1cm - 5a/1year + s) kcal/day
where,
m = weight
h = height
a = age
s = +5 for males and -161 for females
