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. We have divided these into five levels from very light to very heavy. We have included 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.
