Fasting can improve mood and mental clarity from "summary" of Fasting for Life by Francis E. Umesiri
Fasting has been found to have a positive impact on mood and mental clarity. When we fast, our bodies undergo a process called ketosis, where the body starts burning fat for energy instead of glucose. This shift in fuel source can lead to increased production of ketones, which are known to have neuroprotective effects on the brain. Furthermore, fasting has been shown to increase the production of brain-derived neurotrophic factor (BDNF), a protein that helps support the growth and survival of neurons. By promoting the growth of new neurons and protecting existing ones, BDNF can enhance cognitive function and improve mood. In addition to the biological changes that occur during fasting, there are also psychological benefits. Many people report feeling a sense of mental clarity and focus while fasting. This may be due in part to the simplicity of the fasting process – when we eliminate the distraction of food, we can better concentrate on our thoughts and tasks at hand. Moreover, fasting can help regulate the release of certain neurotransmitters, such as serotonin and dopamine, which play a key role in mood regulation. By stabilizing these neurotransmitters, fasting can help improve mood and reduce symptoms of anxiety and depression.- The combination of biological and psychological effects of fasting can lead to an improvement in mood and mental clarity. By giving our bodies and minds a break from the constant influx of food, we can experience a sense of rejuvenation and mental sharpness that can carry over into our daily lives.
