Total Energy Expenditure includes which components?

• A. All the calories burned in 1 day, including basal metabolic rate, non-exercise and exercise related thermogenesis, and the thermic effect of feeding.
• B. Only the calories burned during exercise.
• C. Only the calories burned at rest (basal metabolic rate).
• D. Calories burned during digestion only.

Answer: (A)

Total Energy Expenditure is the sum of all daily energy used by the body: the energy required to keep the body at rest (basal/resting metabolic rate), the energy cost of digesting and processing the food you eat (thermic effect of feeding), and the energy burned through all physical activity, including both planned exercise and everyday movements (non-exercise activity thermogenesis and exercise energy expenditure).

The best answer includes all of these components because TEE accounts for every calorie expended over a 24-hour period. The other options focus on only one component—just exercise, just resting energy, or only digestion—so they don’t capture the full total energy used in a day.
