Research suggests that glucose is involved in the effect of ego depletion on self-control in subsequent situations. Glucose is the primary source of energy for the brain, and when it becomes depleted, it can lead to reduced self-control and decision-making abilities. Restoring glucose levels through consuming sugary drinks or foods has been found to improve self-control and decision-making in subsequent tasks.
