thermic effect of food

,

TEF

The increase in the body's metabolic rate that is produced by the consumption, digestion, metabolism, and storage of food. Foods with relatively low thermic effects include most carbohydrates, since carbohydrates, esp. sugars, cost the body relatively little energy to digest and metabolize. Protein-rich meals have a higher TEF, which is the rationale for low-carbohydrate diets, such as the Atkins and South Beach diets. Synonym: specific dynamic action of food.
