- Recent comprehensive review of 63 scientific articles covering 3,484 participants found no meaningful difference in cognitive performance between fasting individuals and those having regular meals.
- Short-term fasting (median duration of 12 hours) showed no significant overall impact on cognitive skills like memory recall, decision-making, response speed, and accuracy.
- Modest cognitive reductions were observed in fasting intervals over 12 hours, and noticeable declines were noted in children and teenagers, suggesting extended fasting may be riskier for developing brains.
- Cognitive deficits were most evident in food-related tasks (e.g., processing food-related stimuli), while performance on neutral tasks remained largely stable, possibly due to hunger selectively diverting attention.
- Fasting did not significantly impair general cognitive functioning, but performance tended to decline later in the day, possibly amplifying natural circadian concentration dips.
- Fasting has potential health benefits like weight management, improved cardiovascular health, and reduced inflammation, but researchers emphasize it should be seen as a personal tool rather than a universal prescription.
