Which factors are included in the determination of Total Daily Energy Expenditure (TDEE)?

Total Daily Energy Expenditure (TDEE) is the total number of calories that an individual burns in a day, and its calculation takes multiple factors into account. The correct choice includes age, sex, height, weight, and physical activity, all of which are critical in estimating TDEE.

Age affects metabolism; as individuals grow older, metabolic rates generally decline. Sex also plays a role, as males typically have a higher muscle mass than females, leading to increased caloric needs. Height contributes to the overall body surface area, which correlates with caloric expenditure. Weight is a direct factor in determining how many calories are burned at rest and during activity, as larger bodies generally require more energy to maintain basic functions and to move. Finally, physical activity is a significant determinant of TDEE, as the amount and intensity of exercise greatly influence the daily energy expenditure.

All these components combined provide a comprehensive approach to accurately estimate an individual’s energy needs throughout the day, making this option the most complete representation of the factors that influence TDEE.
