Researchers suggest that if you want to reduce the amount that you eat or enhance your diet, it could be a good idea to listen to the sounds that you make. A series of experiments found that people tend to eat less if they are more conscious about the crunching, chomping, and chewing sounds that they make when eating.
In one study, participants wore headphones to listen to either quiet or loud noises while they ate pretzels. The participants exposed to loud noises ate four pretzels, while the quiet noise group ate an average of 2.75 pretzels. Researchers responsible for the study state that sound is a forgotten food sense, but when people are more focused on the sounds that food makes, reduced consumption could result.
These findings were published in Food Quality and Preference on March 15, 2016.
