In which situation will physical activity be considered a major determinant of energy need?
Answer and explanation
Correct answer: When a person performs heavy labour every day
Physical activity is an important determinant of energy requirement because muscles use energy during movement and work. A person who performs heavy labour every day expends much more energy than someone who is sedentary, so that person generally needs more dietary energy to maintain body weight and perform work. Reading labels, drinking water, or washing one plate does not represent sustained, substantial activity. Therefore, option C is correct.
