Why do people eat mutiple times a day? Why do you eat breakfast? Or supper/dinner? Are you hungry? Or is it just your body used to getting its glucose externally? It can relearn to produce it itself. Why do you snack? Are you hungry or are you bored? Or is it glucose again? We can survive without food for as long as a month. How come you can't even last 24 hours? Yes it is external glucose addiction. Which, by the way, can be gotten rid of in just a few days. If you want it.
