Based on oxygen utilization and body mass. The original definition of metabolic equivalent of task is the oxygen used by a person in milliliters per minute per kilogram body mass divided by 3.5. Other definitions which roughly produce the same numbers have been devised, such as: where. kcal = kilocalorie. kg = kilogram. h = hour. kJ = kilojoule.
Partner sex may take a bit more energy, but you're still only burning around 4.2 calories a minute, according to a small study done by scientists at the University of Montreal in 2013.
The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR).. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight.
Definition. The physical activity level is defined for a non- pregnant, non- lactating adult as that person's total energy expenditure (TEE) in a 24-hour period, divided by his or her basal metabolic rate (BMR): [ 2] The level of physical activity can also be estimated based on a list of the physical activities a person performs from day to day.
Basal metabolic rate. Basal metabolic rate ( BMR) is the rate of energy expenditure per unit time by endothermic animals at rest. [ 1] It is reported in energy units per unit time ranging from watt (joule/second) to ml O 2 /min or joule per hour per kg body mass J/ (h·kg). Proper measurement requires a strict set of criteria to be met.

His abbreviated equation for estimating metabolic rate was written with rates of gas exchange being volume/time, excluded urinary nitrogen, and allowed for the inclusion of a time conversion factor of 1.44 to extrapolate to 24-hour energy expenditure from 'kcal per minute" to "kcal per day."
