The human brain evolved in an environment of intermittent food scarcity, and its neurological systems are calibrated for periods without eating. Fasting activates autophagy, the cellular housekeeping process that clears damaged proteins and dysfunctional organelles. It triggers the production of ketone bodies, an alternative fuel that the brain uses with remarkable efficiency. It upregulates brain-derived neurotrophic factor, enhancing synaptic plasticity and neurogenesis. This fully referenced article explores the neuroscience of fasting, what it does to the brain, and why the modern pattern of continuous eating may be depriving the brain of the metabolic challenge it was designed to meet.
