Mind over matter may really work when it comes to managing appetite. Researchers at the University of Birmingham, U.K. have found that recalling foods eaten at lunch has an inhibitory effect on subsequent snacking later the same day. The study is currently in press and will be published in the journal Physiology & Behavior . The effect was observed regardless of the type of snack eaten or palatability. The study also found that meal recall was only effective in decreasing the amount eaten if participants did not have a tendency to overeat.
