Question

What are the 3 components of energy expenditure and how much do each component contribute to overall energy expenditure?

A) Basal metabolic rate, 20%; Physical activity, 40%; Thermic effect of food, 10%
B) Basal metabolic rate, 30%; Physical activity, 50%; Thermic effect of food, 15%
C) Basal metabolic rate, 60%; Physical activity, 20%; Thermic effect of food, 10%
D) Basal metabolic rate, 40%; Physical activity, 30%; Thermic effect of food, 20%

Answer 1

The three components of energy expenditure are basal metabolic rate, physical activity, and thermic effect of food. Option D, with basal metabolic rate contributing 40%, physical activity contributing 30%, and thermic effect of food contributing 20%, is the correct answer.

Step-by-step explanation:

The three components of energy expenditure are:

• Basal metabolic rate (BMR) - This is the energy your body needs for basic, daily activity at rest. It accounts for about 70% of your total energy expenditure.
• Physical activity - This is the energy you use during any movement or exercise. It contributes about 20% to your overall energy expenditure.
• Thermic effect of food - This is the energy required for digestion, absorption, and metabolism of food. It makes up about 10% of your total energy expenditure.

Option D: Basal metabolic rate, 40%; Physical activity, 30%; Thermic effect of food, 20% is the correct answer.
