Title: Does fasting make it hard to think?
Authors: YOUNG, EMMA (AUTHOR)
Source: Psychologist. Mar2026, p11-12. 2p. 1 Diagram.
Subjects: Fasting, Cognitive ability, Age differences, Research methodology, Circadian rhythms, Blood sugar
Abstract: The article focuses on a systematic review and meta-analysis conducted by researchers from Paris Lodron University and the University of Auckland, examining the effects of fasting on cognitive function. The analysis synthesized evidence from over 70 studies and found that, on average, fasting had minimal impact on cognitive performance, although performance declined later in the day. The researchers noted that age and prior fasting experience could influence cognitive outcomes, with fasting children performing worse than their non-fasting peers. They also highlighted gaps in the existing literature, such as the lack of data on blood glucose levels and circadian influences, indicating that further research is necessary to fully understand the cognitive effects of fasting.
