The thermic effect of food (TEF) is the amount of energy the body needs to digest, absorb, metabolize, and store the food you consume. Though the TEF varies somewhat depending on the type of food consumed, about what percentage of the energy content of the meal is used for TEF?

A. 45%B. 0 to 3%C. 20 to 30%D. 10%

D. 10%

Explanation:

Thermic Effect of Food also known as Dietary Induced Thermogenesis is the energy spent by the body to process food and store it. It includes energy expenditure for processes like digestion, absorption, metabolization and storage.

Around 10% of total calorific intake is spent in TEF. Although this percentage can vary according to the type of food. For example, TEF of fat is less than TEF of protein because fat processing is simpler and easier for the body compared to protein processing.
