Want to lose weight? Colorado State University researchers say you may need the ‘Crunch Factor’. They say the noise your food makes while you’re eating plays a role in how much you consume; that hearing the sound of your chewing and chomping and the crunch of bites of food can help you feel fuller. “Sound is typically labelled as the forgotten food sense. But if people are more focused on the sound food makes, it could reduce consumption,” Dr. Ryan Elder, a co-author of the report, said. “When you mask the sound of [eating], like when you watch TV while eating, you take away one of those senses and it may cause you to eat more than you normally would. The effects may not seem huge – one less pretzel – but over the course of a week, month, or year, it could really add up.” The full findings were published this week in the journal, Food Quality and Preference.
