About BMR (Basal Metabolic Rate)

"Basal Metabolic Rate" (sometimes also called "Resting Metabolic Rate") or BMR is an approximate calculation of how many calories you would need to maintain your current weight if you did nothing but stayed in bed all day. This calculation is really only accurate for a certain percentage of people, because your actual BMR depends on other things such as body fat percentage, etc. For this reason, we also show BMR at plus or minus 20 percent, so you can get a better idea of the range.

When computed with your "lifestyle" number, this gives your overall calorie needs in a given day.
