What concept describes the higher energy expenditure the body uses when digesting protein compared to fats and carbohydrates?
Answer
Thermic effect
The thermic effect of food (TEF) is a physiological process where the body expends energy, or burns calories, in the process of digesting, absorbing, transporting, and storing the nutrients consumed in a meal. Protein has a significantly higher thermic effect compared to fats and carbohydrates. This means that a portion of the calories consumed from protein are burned off just through the digestive process itself, providing a small but measurable advantage for metabolic rate maintenance and calorie burning, which is critical while trying to achieve fat loss.
