Researchers at Brigham Young University and Colorado State University have found that listening to yourself eat can have an effect on how much you actually eat. We are talking about the sounds that you hear when you are actually eating the food, known as the "the crunch effect." When you are watching television, playing with your phone, or listening to music, you are not really paying attention to anything else, let alone how you are eating or how much.
Study co-author Gina Mohr, of CSU, said: ‘For the most part, consumers and researchers have overlooked food sound as an important sensory cue in the eating experience.’
Past studies have focused more on other senses such as thoroughly chewing your food and feeling it in your mouth, how your food smells, tastes, and allowing time for your body to feel full. Three separate and more recent experiments have been performed and each one found that even thinking about the sounds that are made by chewing foods can lead a person to eating less. It has even been discovered that if the chewing sound is really intense and loud, people will eat even less of that food item. The volume of the noise in a room will definitely effect how much each person in the room eats. If they cannot hear themselves chew, then they will eat significantly more food. Crunchy vegetables like carrots, celery, and broccoli should be eaten while listing to loud music so you will eat more of them ( just kidding, maybe).
Simple tricks such as the color and size of your plate can make a difference on how much you eat too. Especially those who have a tendency to over eat will benefit from mindfulness when eating. We encourage our clients and athletes to be mindful during their training and throughout the day. Paying attention to all of your senses: hearing, sight, touch, smell, and taste will allow you to really experience NOW! This is just another example of how listening to yourself will improve the quality of your life. Please make time to unplug and disconnect from the chaos.
