Energy expenditure refers to the amount of energy that a person uses to conduct daily activities. It's typically measured in calories and comprises three main components:

1. Basal Metabolic Rate (BMR): This is the amount of energy your body needs to maintain basic physiological functions while at rest, such as breathing, circulating blood, and regulating body temperature. BMR accounts for about 60-75% of total energy expenditure in sedentary individuals.

2. Physical Activity: This includes the energy expended during any form of physical movement, such as walking, exercising, or doing household chores. The amount of energy expended in physical activity varies greatly among individuals and can account for 15-30% of total energy expenditure.

3. Thermic Effect of Food (TEF): This is the energy required for digestion, absorption, and disposal of ingested nutrients. It accounts for about 10% of total energy expenditure. The TEF is higher for protein and carbohydrates than for fats.
