We Were Wrong About Fasting Study Finds
A recent comprehensive review has found that fasting does not significantly impact cognitive performance in healthy adults. The analysis, which included data from 63 studies with nearly 3,500 participants, showed no meaningful differences in cognitive abilities between those who fasted and those who ate regularly. Researchers suggest that individuals can pursue fasting without fear of impairing their mental sharpness.
- ▪The review analyzed 63 scientific articles and 71 independent studies.
- ▪Participants included a total of 3,484 individuals.
- ▪No significant cognitive performance differences were found between fasting and non-fasting individuals.
