What term describes the increase in caloric expenditure resulting from the digestion of food?

The term that describes the increase in caloric expenditure resulting from the digestion of food is the Thermic Effect of Food (TEF). This process refers to the energy required for the digestive system to break down food, absorb nutrients, and metabolize them for energy. TEF accounts for a certain percentage of the total daily energy expenditure and varies based on the composition of the food consumed—protein has a higher thermic effect compared to carbohydrates or fats.

Understanding TEF is important for nutritional analysis and weight management because it highlights how different macronutrients affect energy expenditure differently. This knowledge can aid in creating dietary plans that optimize caloric burning through meal composition, thereby assisting individuals in managing their weight effectively.
