Abstract
Intermittent fasting has received increasing scientific and public attention in recent years. The study by Hromatko et al. investigated whether time-restricted feeding, a form of intermittent fasting, improves cognitive performance and subjective-emotional well-being. This commentary discusses the most important results and relates them to previous studies on this topic. A major limitation of this new trial is its relatively short duration of only two months. I then link the idea of improving mental functions in healthy people to the discussion of cognitive or neuroenhancement. Finally, a current example of the communication of intermittent fasting in the media is discussed, which attracted public attention with a surprising message.
