Homeostasis, body temperature regulation, central nervous system function, hormone and chemical production and electrolyte balance, as swell as every day function needed for life, are part of the resting metabolic rate.

The higher the metabolic rate the more calories the body burns and the easier it is to maintain a healthy bodyweigth and composition. The human body burns calories in two ways.

The first way is through involuntary activate, such as the beating of the heart, the inhaling of oxygen and maintanance of body temperature.

The second is through voluntary activities such as exercising and moving around throughout the day.
