The first study revealed how eating speed affects people's calorie intake, which was conducted by researchers at the University of Rhode Island. The researchers provided spaghetti to 30 women who participated in the experiment. In the first stage of the test, these women were told to eat quickly and finish all the food in about 9 minutes. In the second phase of the test, the researchers encouraged them to slow down their eating, chew a mouthful of rice 15 to 20 times before swallowing it, and finish it after about 29 minutes. Thirty women in the experiment were asked to stop eating only when they felt full.
The results showed that these women consumed an average of 67 calories less when they chewed slowly. If you eat 67 calories less every day, it means that you can lose 7 kg a year (1 kg = 0.95438+08474 kg). Moreover, they also say that it is easier to feel full after slowing down eating. However, when they eat quickly, they may have eaten too much before the body signals satiety.
The second study shows that people who chew slowly consume more energy when they eat the same amount of food after meals. This research was conducted by a research team led by Professor Lin Zhixiang of tokyo institute of technology. In the experiment, they asked 10 men with an average age of 25 to keep quiet for 20 minutes, then ate a piece of food with a calorie of 300 kilocalories, and compared the energy consumption when eating it as soon as possible and chewing it slowly as much as possible.
The data showed that it took the men 10 an average of 1 minute 43 seconds to eat and chew 137 times as soon as possible. When trying to chew slowly, it takes an average of 8 minutes 17 seconds and chews 702 times. It is found that if you eat as soon as possible, the energy consumption per kilogram of body weight is 7 calories within 90 minutes after eating, but if you chew slowly and try to grind the food in your mouth before swallowing, this value is 180 calories, which is significantly different. Moreover, the researchers also found that when chewing slowly, the blood flow in the digestive tract will also increase significantly. In addition, in the case of eating food with a calorie of 100, the same result is also shown. It can be considered that the more chewing times, the more energy is consumed.
After reading the above two studies, are you telling yourself silently that you must chew slowly when eating? Good habits need to be adhered to, and the effect can only be seen after doing them.
