A Tired Brain is a Hungry Brain
When the brain experiences a reduction in carbohydrates or glucose, it triggers a survival mechanism characterized by the release of cortisol and adrenaline, indicating a dangerous state. Notably, 14% of this glucose reduction affects the prefrontal cortex, which plays a crucial role in executive functions and moral decision-making. This deprivation significantly diminishes the ability to make sound dietary choices, as the brain instinctively craves quick sources of glucose. Thus, biological drives can overpower willpower, resulting in a struggle against one's own body's needs. Additionally, sleep deprivation exacerbates this condition, making it harder to resist unhealthy food. Ultimately, individuals should recognize that these cravings and challenges may not stem from personal shortcomings, but rather from the fundamental workings of their physiology.
