Physical activity is a component of which metabolic measurement?

The correct answer is Daily Caloric Expenditure (DCE). This measurement takes into account the total number of calories burned throughout the day, including calories expended during physical activity. Physical activity significantly influences DCE, as it represents a large portion of the energy expenditure above the basal level, contributing to weight maintenance and overall energy balance.

Basal Metabolic Rate (BMR) measures the energy expended while at rest in a neutrally temperate environment and does not include physical activity. It strictly focuses on the basic metabolic processes necessary for sustaining life, such as breathing and circulation, and does not account for any additional calorie burn from physical movement.

Resting Energy Expenditure (REE) is similar to BMR but takes into account the energy expended during all states of rest, including daily activities. While REE can include minimal energy from daily movements, it does not emphasize physical activity in the way that Daily Caloric Expenditure does.

The Thermic Effect of Food (TEF) refers to the energy required for digestion, absorption, and metabolism of food. It is a separate component of total energy expenditure, which does not directly include the effects of physical activity.

In summary, Daily Caloric Expenditure incorporates energy from physical activity, making
