if you are hungry, your body's awareness of that motivation was made possible through a negative feedback loop.

Explanation:

Negative feedback is a kind of mechanism that causes a decrease in a certain kind of function. This response is generated in response to a stimulus.

In the case of hunger, negative feedback is generated by a slow rate of metabolic activities. The metabolic functions of the body are reduced in order to save energy. This stimulus acts as a factor to generate the negative feedback loop to the brain and in repose hunger pangs will be generated.
