Discuss the role played by the thermic effect of food (TEF) component of total energy expenditure (TEE)
TEF is the energy required to digest, absorb, and metabolize nutrients following a meal. In other words, it is the cost associated with your body's utilization of the foods you eat. The amount of energy associated with TEF depends on the amount of food consumed and the types of nutrients present in that food. In general, more energy is required to process large amounts of food, and high-protein foods have higher TEFs than do fatty foods. Considering that meals generally contain a mixture of nutrients, TEF is estimated to be about 5-10 percent of total energy intake. For example, after consuming a 500-kilocalorie meal, a person typically expends 25-50 kilocalories (TEF) just to digest and utilize the nutrients it contains.
