@Kristine none of them. It's carbs and sugars. I mean it's sugars and more sugars. Unhealthy but hey... we can't live like a sick person just to die healthy 😉
@ranx the body for sure needs sugar to work. Technically, your body then also needs insulin to use that sugar as energy. Regards from the diabetic. All these biochemical stuff is the next, not necessary, meta level to drive psychological energy rather than physical energy. Actual sugar also contributes to those pathways though.
