Chewing food more helps people consume less food and lose weight, a new study has shown.
According to researchers from Harbin Medical University in China, those who chewed food 40 times consumed about 12 percent less calories than those who chewed only 15 times.
The study is posted on the latest version of the Journal of Clinical Nutrition.
Researchers conducted two experiments with 14 slim and 16 obese males.
In the first test, doctors counted the frequency of chewing in each group after serving them equal sized pork pies. Although the size of their bite was similar, the obese group tended to swallow faster.
In the second test, researchers had all participants chew 15 times per bite, and then chew 40 times. They all consumed 11.9 percent less when they chewed more.
The more you chew, the longer it takes for the brain to receive signals from the stomach to control appetite, according to the research.
Meanwhile, Adam Drewnowski from University of Washington Center for Obesity Research said that because there are foods that cannot be chewed like soup or ice-cream, there is a limit to the weight to be lost through increased chewing.
