How much of the daily energy expenditure can the thermic effect of food account for?

The thermic effect of food (TEF) refers to the energy required for the digestion, absorption, and metabolism of food. It is considered an important component of the total daily energy expenditure (TDEE), which also includes basal metabolic rate (BMR) and physical activity levels.

The correct range for the thermic effect of food typically accounts for approximately 10-15% of daily energy expenditure. This percentage can vary based on several factors, including the macronutrient composition of the diet—protein has a higher thermic effect compared to fats and carbohydrates. A well-balanced diet that incorporates a variety of foods can lead to this optimal range of energy expenditure, demonstrating the efficiency of the body's processing systems.

The other ranges do not accurately represent the commonly accepted estimates for the thermic effect of food in relation to daily energy expenditure, making the selected answer the most appropriate one.
