Basal Metabolic Rate (BMR)

Your Basal Metabolic Rate shows the number of calories your body needs to operate. This doesn't account for any activity, it's simply the energy needed to sustain a heartbeat, breathing and normal body temperature. It measures the body at rest, not sleep, at room temperature.

Formula:
BMR for males = 66 + (13.7 x w) + (5 x h) - (6.8 x y)
BMR for females = 655 + (9.6 x w) + (1.8 x h) - (4.7 x y)

where:
h = height in centimeters (inches x 2.54)
w = weight in kilograms (pounds ÷ 2.2)
y = age in years
