Basal Energy Expenditure Calculator (BMR)

Basal energy expenditure, also  popularly known as actual basal metabolic rate (BMR), refers to the minimum rate of functional energy being expended by an animal or human for the purpose of maintaining life; usually expressed in daily measures of expenditure. This is limited to the biological requirements for the fundamental extension of existence when the being is at rest in a neutral and temperate environment and particularly refers to the basic functioning of its vital organs; a state of complete rest and awake alertness without tension of the un-stimulated nervous system.

Several factors affect this rate such as age and loss of body mass, which increase it, and cardiovascular exercise and muscle mass which also heighten the energy expenditure level. Illnesses, foods, and beverages already consumed, the temperature of the environment, and the individual's levels of stress also affect energy expenditure. This rate is commonly computed using the widely used Harris-Benedict equations and is significant in weight loss issues because it is actually the highest form of calorie energy expenditure. Moreover , knowledge of your functional basal metabolic rate facilitates weight management because you compute how much energy you should consume in order to increase, maintain, or decrease weight.

For the purpose of computing basal energy expenditure, the factors for men and women in terms of total heat production per 24 hours at complete rest in kcals per day must be determined, as well as which factors are different between men and women. You must also know your weight in kilograms, your stature or height in centimetres and age in years. Thus, for men, you add 66.5 to 13.75 times your weight, plus 5.003 times height minus 6.775 times your age. For women, you add 655.1 to 9.563 times your weight, plus 1.850 times your height minus 4.575 times your age. However, there are websites with basal energy expenditure calculators that will automatically compute the factors that you input. With this knowledge, you move closer to proper weight management.
