What is BMR?
BMR estimates the calories your body needs for basic functions at rest, such as breathing, circulation and cell repair.
Formula used
Male: BMR = 10W + 6.25H - 5A + 5. Female: BMR = 10W + 6.25H - 5A - 161.
W is weight in kg, H is height in cm and A is age in years. Real calorie needs also depend on activity, sleep, health and body composition.
