Your BMR (Basal Metabolic Rate) is the estimated minimum level of energy required to sustain the body’s vital functions when at rest. The Harris-Benedict formula is used to calculate the BMR (Basal Metabolic Rate).

Note: Will underestimate caloric needs for the extremely muscular and will overestimate caloric needs for the extremely overweight.
Basal Metabolic Rate (BMR)
Why is calculating your Basal Metabolic Rate Important?
Your BMR, or basal metabolic rate (metabolism), is the energy (measured in calories) expended by the body at rest to maintain normal bodily functions. This continual work makes up about 60-70% of the calories we use (“burn” or expend) and includes the beating of our heart, respiration, and the maintenance of body temperature. Your BMR is influenced by a number of factors, including age, weight, height, gender, environmental temperature, dieting, and exercise habits.
Because of the increased activity of cells undergoing division, the younger the person, the higher (faster) the metabolism. And the taller and heavier a person is, the faster their metabolism. Because of the greater percentage of lean muscle tissue in the male body, men generally have a 10-15% faster BMR than women. Restrictive and traditional diets may cause your BMR to drop as much as 20%. People living in tropical or very cold environments generally have BMR’s 5-20% higher than those living in more temperate climates. In general, depending on the intensity and duration, consistent exercise will also increase your BMR.
