Total daily energy expenditure refers to the complete amount of energy, measured in calories, that your body uses in a 24-hour period. This includes all the calories burned through various activities such as exercise, daily movements, and essential bodily functions like digestion and maintaining body temperature.
This concept encompasses several components: the resting metabolic rate, the thermic effect of food (calories burned through eating and digesting food), and the energy expended during physical activity. Understanding total daily energy expenditure is essential for personal trainers and individuals looking to manage weight, optimize nutrition, or improve fitness levels since it provides a comprehensive view of the calories burned throughout the day.
While resting metabolic rate and basal metabolic rate both refer to the calories burned at rest, they do not account for the additional calories burned through daily activities and the thermic effect of food, which are included in total daily energy expenditure. A metabolic set point typically refers to the body's natural tendency to maintain weight within a certain range over time, which is a different concept altogether.
