Final answer:
The average Total Daily Energy Expenditure (TDEE) varies greatly and is influenced by several personal factors, with adult males typically around 2,400 to 3,000 calories and adult females around 1,800 to 2,400 calories per day.
Step-by-step explanation:
The Total Daily Energy Expenditure (TDEE) is the amount of calories a person burns in a day through activity and maintaining basic bodily functions. The average TDEE varies significantly depending on factors such as age, sex, weight, height, and level of physical activity. Adult males typically have a TDEE ranging from 2,400 to 3,000 calories per day, while adult females usually range from 1,800 to 2,400 calories per day. However, these numbers can vary widely on an individual basis.
To calculate an individual's TDEE, one would need to consider their Basal Metabolic Rate (BMR), which is the number of calories necessary for maintaining life-sustaining functions at rest, and then adjust for their physical activity level. Various online calculators or formulas, such as the Mifflin-St Jeor or Harris-Benedict equations, can help estimate TDEE.
