BMR or basal metabolic rate is the energy requirement to maintain life. It is measured at rest, but not asleep in a thermo-neutral environment in the post-absorptive state(what this means is that it is just measured when resting, not sleeping). It can be measured directly or indirectly, or it can be estimated as we are doing here. So lets get started.

To estimate your BMR, input:

Physical characteristics: BMR   
Age in years     
Weight in pounds 
Height in inches 

kcal/day for men 
kcal/day for women

BMR can also be estimated as 70 W0.75 = 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 that are above basal. Once you have calculated the BMR above, you can enter the minutes you spend in your various other activities each day. I have divided these into five levels from very light to very heavy. Included 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.
