ABSTRACT
Energy homeostasis is the balance between energy intake and energy output. When intake exceeds output, energy is stored, primarily in the form of adipose tissue. When output exceeds intake, these energy stores are drawn upon to provide energy to support the ongoing metabolic needs of the organism. Although one cannot separate the brain from the body in terms of this regulatory system, it seems very likely that the brain is the conductor of the complex orchestra that oversees this complex process. Regulation of such homeostasis requires a constant dialogue among the external and internal environments and the brain (Figure 14.1).
