The energy expenditure associated with food digestion and absorption is called:

• A. resting energy expenditure (REE)
• B. basal metabolic rate (BMR)
• C. thermic effect of food (TEF)
• D. total daily energy expenditure (TDEE)

Answer: (C)

Verified step by step guidance

1. Understand the concept of energy expenditure: Energy expenditure refers to the amount of energy (calories) the body uses to perform various functions, including digestion, absorption, and metabolism.
2. Learn about the thermic effect of food (TEF): TEF is the energy required to digest, absorb, and metabolize food. It accounts for approximately 10% of total daily energy expenditure (TDEE).
3. Differentiate TEF from other terms: Resting energy expenditure (REE) refers to the energy used by the body at rest for basic functions like breathing and circulation. Basal metabolic rate (BMR) is similar to REE but measured under stricter conditions. Total daily energy expenditure (TDEE) includes all energy used in a day, including TEF, physical activity, and REE.
4. Recognize the role of TEF in metabolism: TEF varies depending on the type of food consumed. Proteins generally have a higher thermic effect compared to carbohydrates and fats, meaning they require more energy to digest and absorb.
5. Apply this knowledge to the problem: The energy expenditure associated specifically with food digestion and absorption is called the thermic effect of food (TEF), distinguishing it from other components of energy expenditure like REE, BMR, and TDEE.
