Final answer:
Total Daily Energy Expenditure (TDEE) is calculated by determining the average amount of energy you use in a day. This can be done by measuring the basal metabolic rate (BMR) which is the amount of energy your body needs for normal, basic, daily activity. BMR can be measured directly using a calorimeter or indirectly using methods like the Benedict-Roth spirometer method.
Step-by-step explanation:
Total Daily Energy Expenditure (TDEE) is calculated by determining the average amount of energy you use in a day. This can be done by measuring the basal metabolic rate (BMR) which is the amount of energy your body needs for normal, basic, daily activity. BMR can be measured directly using a calorimeter or indirectly using methods like the Benedict-Roth spirometer method. By knowing your BMR and adding the energy expended through physical activity, you can calculate your TDEE.
