What formula represents the calculation of predicted TDEE?

The calculation of Total Daily Energy Expenditure (TDEE) is best represented by the concept of combining involuntary and voluntary metabolism. TDEE is the total amount of energy that a person expends in a day and includes several components: the Basal Metabolic Rate (BMR), which accounts for the energy expended in resting functions; the energy expended through physical activity (voluntary metabolism); and the energy used in the thermic effect of food.

In this context, considering both involuntary metabolism (like BMR) and voluntary metabolism (like that from physical activities) provides a more accurate representation of how energy is utilized throughout the day. Thus, while other formulas focus on specific components of energy expenditure, recognizing both involuntary and voluntary processes together gives a comprehensive understanding of TDEE.

This holistic approach reflects a more complete view of energy expenditure, which is essential for accurate nutritional analysis and weight management.
