TEF-thermic effect of food

Explanation:

The thermic effect of food is the energy needed for digestion, absorption, and removal of ingested nutrients. Its magnitude relies on the components of the food consumed: Carbohydrates has 5 to 15% of the energy ingested while Protein 20 to 35% of the energy ingested.

The thermic effect of food can be determined by multiplying the total calories derived from food by 10%. For example, a 2000 calories diet a day will consume approximately 200 calories in digesting the food.
