Energy expenditure

Energy expenditure refers to the total amount of energy your body uses to function and carry out daily activities. It includes three main components: basal metabolic rate (energy used at rest to keep your body alive), physical activity (movement like walking or exercising), and the energy required for digesting food. Your body needs this energy for everything from breathing and maintaining body temperature to walking and thinking. Factors like age, weight, muscle mass, and activity level influence how much energy you burn. Understanding energy expenditure helps manage weight and overall health by balancing the calories you consume with those you burn.
