WILL REGULARLY SKIPPING breakfast make it harder to concentrate? According to a recent Psychological Bulletin review, the answer is no. Scientists have found enough evidence to firmly say that short-term fasting does not cause a dip in mental clarity.
“The idea that fasting interferes with mental performance probably stems from how we feel when hungry—tired, distracted, and irritable,” explains David Moreau, PhD, associate professor in the School of Psychology at the University of Auckland in New Zealand and coauthor of the study. “It’s natural to assume that those sensations reflect poorer cognitive function. Some early studies supported this view, but when you pool the evidence, those effects largely disappear.”
