Eating too fast is the root cause of obesity, but why does it lead to fatness? It is generally believed to be related to the satiety center in the brain. During a meal, a certain amount of food accumulates in the stomach and then signals are sent to the brain. However, people who eat too fast consume more food than necessary before the brain receives the signal. A survey by Professor Yasushi Ishihiro of Osaka University and others showed that people who eat too fast and are too full have a higher probability of obesity compared to those who chew and swallow slowly. It just seems that there are other reasons besides the satiety center. Perhaps it is related to the type of food, the more people who eat too fast, the less food fiber they consume. Regarding the speed of eating, a professor at Kanagawa University of Technology believes that swallowing a meal after chewing only two or three bites will not taste the original flavor of the food. Food contains both surface flavor and internal flavor that comes out from the inside. If you can chew well and taste carefully, a small amount of food can increase the satisfaction and satiety of your stomach. Experiments have shown that women who chew slowly have a tendency to lose weight, and a small amount of food can make them feel full. But for men, just by increasing the number of chewing does not help to reduce weight. But reduce the amount of food, but will make people feel hungry, so it is important to consciously control the amount of food in the “eight minutes full”. Although it takes about 6 months to develop the habit of chewing slowly, but a little weight loss will give you the motivation to continue. In any case, it is very important to chew slowly and consciously taste the food when eating.
