Metabolic rate (kcal per day) = 1.440 (3.9 VO 2 + 1.1 VCO 2) where VO 2 is oxygen consumption in litres per minute and VCO 2 is the rate of carbon dioxide production in litres per minute. The formula can also be written for units of calories per day where VO 2 is oxygen consumption expressed in millilitres per minute and VCO 2 is the rate of ...
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 ...

[2] The CRON-diet involves calorie restriction in the hope that the practice will improve health and retard aging, while still attempting to provide the recommended daily amounts of various nutrients.

The physical activity level (PAL) is a way to express a person's daily physical activity as a number and is used to estimate their total energy expenditure. [1] In combination with the basal metabolic rate, it can be used to compute the amount of food energy a person needs to consume to maintain a particular lifestyle.
