Will my mind clear if I don't eat

Not eating may lead to short-term mental clarity, but long-term hunger can reduce brain function. In a state of hunger, the lower body will preferentially break down liver glycogen for energy supply, which may lead to a temporary increase in alertness; Continuous lack of nutrition can lead to insufficient blood sugar and decreased attention. In the early stages of hunger, the body maintains blood sugar levels by breaking down stored glycogen. At this time, the secretion of hormones such as adrenaline increases, which may temporarily improve concentration and cognitive acuity. This phenomenon is similar to the fight or flight response and is an evolved survival mechanism. Some people report an increase in work efficiency during the early stages of intermittent fasting, which is related to this physiological change. After not eating for several hours, liver glycogen gradually runs out, the brain lacks glucose supply, and cognitive function begins to decline. Neurons are unable to effectively transmit signals, resulting in delayed responses, decreased memory, and emotional distress. Long term dieting may cause energy metabolism disorders in brain cells, increasing the risk of anxiety and depression. Insufficient nutrition during adolescent brain development may also affect the development of the prefrontal cortex, leading to impaired decision-making and self-control.

It is recommended to maintain a regular diet and choose low glycemic index foods such as oats and whole wheat bread to maintain blood sugar stability. When hungry, a small amount of nuts can be used to supplement healthy fat and protein, avoiding long periods of fasting for work and study. If you need to improve concentration, it is recommended to engage in moderate exercise, deep breathing, and other healthy methods instead of intentionally starving.
