Basal Metabolic Rate

Basal Metabolic Rate (BMR) is the number of calories your body burns at rest to maintain normal bodily functions. This includes breathing, pumping of heart, digestion and maintaining normal body temperature. It is the amount of calories per day your body burns without taking into account your physical activity. BMR changes with age, weight, height and gender.

On an average our body needs 70 calories per hour to sustain bodily functions at rest. This may be slightly more when awake and less when asleep. BMR increases with body temperature, hence BMR increases with fever and you burn more calories. For every 0.5 degrees celsius increase in body temperature, BMR increases by 7%.
