A couple of simple cues could make people waste substantially less food in places such as hotels, schools, and hospitals, researchers say. The study “‘nudging’ hotel guests to reduce food waste as a win-win environmental measure”, tackled one of the most notorious spots for food waste: the buffet. For about six weeks in 2012, seven hotel restaurants offered their diners smaller plates. Another seven hotel restaurants posted a sign saying, “Welcome back! Again! And again! Visit our buffet many times. That’s better than taking a lot once.” The study authors reasoned that this suggestion would prompt people to take smaller portions rather than loading up their plates with food they couldn’t finish.
