The speed of eating not only affects the absorption and digestion of food, but also influences the amounts of food taken in. The centre directive system which controls you when to begin eating and when to stop eating, is in your brain. The brain gives an order to gain hormone and sufficient lever of intestines and stomach ect, such kind of signals. The transference of the signals need a process. Somebody once did research in this aspect, which found it needed almost 20minutes. If you eat too quickly, there is no doubt that you will take in extra food in the postponed process. From this point of view, you had better chew and swallow food slowly, which can prolong the time of having a meal. You should behave like an epicure who savors every kind of food discreetly, which can not only help you enjoy the process of having a meal completely, but also benefits you to build a healthy figure.
