Total daily energy expenditure, or TDEE, is just jargon for what most of us know as metabolism. In simpler terms, it’s about understanding how your body burns energy throughout the day.
Energy expenditure, often estimated as the total daily energy expenditure (TDEE), is the amount of energy burned by the human body. Causes of energy expenditure
In counting energy expenditure, the use of a resting measurement (RMR) is the most accurate method for estimating the major portion of Total daily energy expenditure (TEE), thereby giving the closest approximations when planning & following a Calorie Intake Plan.
The Estimated Energy Requirement, , is the estimated number of daily kilocalories, or Calories, an individual requires in order to maintain his or her current weight. For a person with a body mass of m {\displaystyle m} (kg), height of h {\displaystyle h} (m), age of a {\displaystyle a} (years) and Physical Activity PA {\displaystyle {\text{PA ...
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.
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 ...

However, the ratio of total daily energy expenditure to resting metabolic rate can vary between 1.6 and 8.0 between species of mammals. Animals also vary in the degree of coupling between oxidative phosphorylation and ATP production , the amount of saturated fat in mitochondrial membranes , the amount of DNA repair , and many other factors that ...
