Question

_________________ IS THE SMALLEST DAILY CONTRIBUTOR TO ENERGY EXPENDITURE BUT AN IMPORTANT INDICATOR OF WEIGHT LOSS

A) Physical activity
B) Basal metabolic rate (BMR)
C) Thermic effect of food (TEF)
D) Resting metabolic rate (RMR)

Answer 1

The smallest daily contributor to energy expenditure but an important indicator of weight loss is the Thermic Effect of Food (TEF), which represents about 10% of the total energy expenditure.The correct answer is option C.

Step-by-step explanation:

The smallest daily contributor to energy expenditure but an important indicator of weight loss is the Thermic Effect of Food (TEF). TEF refers to the energy required by the body to digest, absorb, and process the nutrients in our food.

While the Basal Metabolic Rate (BMR) accounts for approximately 70% of daily energy expenditure by fueling the basic functions of the organs, TEF is much smaller, typically around 10% of total energy expenditure.

However, TEF can affect weight loss, as it is the energy used for processing food which can vary based on the type and amount of food consumed.The correct answer is option C.
