Basal Metabolic Rate Calculator

This calculator will calculate your BMR (Basal Metabolic Rate) and your AMR (Active Metabolic Rate). 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. And when you go on restrictive, traditional diets, your BMR
can drop by 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 can also increase your BMR.

BMR can also be estimated as 70 W^0.75 = kcal/day, where W is body weight in kilograms.

Obviously, there is more to life than just resting in that temperature-neutral environment. You must also have energy from your diet to support your activities above basal. Once you have calculated the BMR above, you can enter the minutes you spend in your various other activities each day. There are five levels from very light to very heavy. There are a few examples of each category to allow you to gauge where a given activity might fit. The result is only an estimate, but should give you an idea of your daily caloric needs.
