I’ll try to keep it as ELI5 as possible.

There are chemicals and mechanisms in your body that tell you when you are hungry and when you are full.

The body releases chemicals which signal your brain that you should eat. This feeling is known as hunger. There are also chemicals released by your body that let you know that you are full.

These chemicals can be released based on our internal clock, how our body feels time is moving by, and other senses within our body that let other parts of the body know their situation.

The reason we do not get this feeling when we are asleep is because our body and mind are working on other processes.
