Human energy expenditure

Human energy expenditure refers to the total amount of energy, measured in calories, that a person uses to maintain bodily functions and perform activities throughout the day. This includes the energy needed for essential processes like breathing, circulation, and digestion, known as the Basal Metabolic Rate (BMR), as well as additional energy spent during physical activities and the digestion of food. Factors such as age, weight, activity level, and gender influence how much energy a person expends. Understanding energy expenditure helps in managing health, weight, and nutrition effectively.
