How does the energy available in the body play a role in the regulation of hormones in humans

Lots of energy being available due to glucose may increase blood pressure. This signals the release of insulin to store this glucose as glycogen in muscles and liver.

Other answers may include the regulation of sleep hormones, or hormones that signal it's time to eat, etc.
