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.

For an average person, resting metabolic rate accounts for 70% of calories consumed, physical activity accounts for 20%, and energy required to digest and metabolize food (the thermic effect of food) accounts for 10%.

Protein-rich foods have a high thermic effect (the energy used in digestion, absorption and distribution of nutrients) which allows the body to burn more calories to digest it.
Ashley Binns, a doctoral student in kinesiology and exercise science who led the study at the University of Arkansas, said the goal was to determine the interaction between the thermic effect of food and exercise on the body's total energy expenditure, as measured in calories.

TRUTH There are some foods, such as fibrous vegetables and lean proteins, that have a high thermic effect and a low calorie density - which means much of the calories in these foods are burned off during digestion - but that's not the same as burning fat from your body.
