Question

Quizplus · Accepted Answer

The maintenance processes that keep you alive, such as breathing, circulating blood, and maintaining body temperature, require a significant amount of energy. These processes are known as basal metabolic rate (BMR) and account for approximately two-thirds of your energy intake. Emotional expression and physical activity also use energy, but they do not make up the majority of energy expenditure. The digestive process also uses some energy, but it is not a significant portion compared to BMR.
