Which of the following components typically accounts for 10% of Total Energy Expenditure?

The thermic effect of food (TEF) is responsible for approximately 10% of total energy expenditure. TEF encompasses the energy required for digestion, absorption, and metabolism of nutrients after eating. When you consume food, your body uses energy to process it, which includes breaking down nutrients and metabolizing them for use or storage.

The other components of total energy expenditure include resting energy expenditure, which accounts for the largest portion (about 60-75%), and physical activity expenditure, which varies widely depending on levels of activity but can represent a significant portion of energy expenditure for active individuals. Basal metabolic rate is similar to resting energy expenditure but refers specifically to the energy expended at rest in a neutrally temperate environment. By understanding these proportions, one can see why TEF is unique in its contribution, allowing for a clearer picture of total energy expenditure in relation to macronutrient intake and overall dietary habits.
