Chew 40 times to Reduce Weight
According to the Daily Mail, scientists from Harbin Medical University, China, performed two types of research on 16 slim men and 14 men with obesity. They wanted to examine whether there are differences in the habit of chewing on these two groups of men.
Each person is given pork pies. Then recorded with hidden cameras to examine how many times they chewed before swallowing the food. The first result is that obese men chew as much as slim men, but they swallow food much faster.
Then the research was resumed, the two groups were again given pork pies with a requirement to chew as much as 15 times and then swallow it. Then they were given more and chewed as much as 40 times.
The result showed that when the volunteers chewed longer, they consumed 11.9 percent fewer calories, regardless of whether they were slim or obese. A blood test taken 90 minutes after ingestion of the food. From there was also known that by chewing more, ghrelin levels were lower. Ghrelin is a hormone that sends hunger signals to the digestive system.
Catherine Collins, dietician at St. George’s Hospital, London, said: “When chewing longer, we will pay more attention to taste, smell, texture that makes us aware of how much we had eaten.”
She added that, unlike when swallowing food quickly, we are not aware that we have eaten much. Finally, 10 minutes later, the hunger comes back.
