BMR is short for Basal Metabolic Rate. Your Basal Metabolic Rate is the number of calories required to keep your body functioning at rest, also known as your metabolism.
What affects my BMR?
Anything that results in an increase to your metabolic rate will increase your BMR. This includes exercise, stress, fear and illnesses.
Your BMR is relative to body mass, age, weight and height. It is also affected by your gender; as it widely regarded that men need more calories than women.
There are 2 formulae used to calculate BMR, in [kcal / 24hrs] for men and women respectively:
- BMR for Men = 66.47 + (13.7 * weight [kg]) + (5 * size [cm]) − (6.8 * age [years])
- BMR for Women = 655.1 + (9.6 * weight [kg]) + (1.8 * size [cm]) − (4.7 * age [years])
