Homeostasis refers to the maintenance of a stable internal temperature and environment that enables the systems in the body, specifically, metabolism, to work to maximum efficiency. Metabolism is the amount of energy the body extracts, stores and uses to maintain itself.

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
