Patients at the young end of the age range for a given equation require more energy. Patients at the high end of the age range for a given equation require less energy. Effects of age and body mass may cancel out: an obese 30-year-old or an athletic 60-year-old may need no adjustment from the raw figure.
The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR)..

The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
