How Is Fasting Affecting Brain Oxygenation And Cognition?, Viviana Garcia, Stefan Keslacy, Axel Munoz, Ceren Acik

International Journal of Exercise Science: Conference Proceedings

Human beings in nearly all societies have experienced the effect of intermittent fasting (IF). It was either imposed because food was scarce or chosen for religious purposes. The beneficial effect of IF on lifespan and the whole organism has been known since the 1930’s. It has been well established that IF reduces the risk of cardiovascular and metabolic diseases. It also appears that IF protects neurons. Several mechanisms have been identified such as increased corticosterone and heat-shock protein-70. One of the most recent beneficial effects of IF on neurons was identified to be mediated by brain-derived neurotrophic factors and ketone …
