Why Eating Fast Causes Us to Gain Weight

Our appetite is controlled by our satiety and feeding centers in our brain. Once food is in the stomach, glucose in the blood increases. Then, blood-sugar and insulin increase. This stimulates the satiety center which makes us feel full. At the same time, while we feel full, the feeding center becomes inactive which tells us to stop eating. When we become hungry, the feeding center becomes active again and we want to eat.

It takes us 15 to 20 minutes to start feeling full after we start eating. Therefore, those who eat fast eat too much before they feel full. When they continue this, they cannot exactly feel when they are full or hungry, causing them to eat food while they're not hungry.

Those who usually finish eating first should try to keep the same pace as others. This will work not only to stop overeating but also makes those eating with you feel more comfortable. It is also more polite this way. When you eat food alone, it is recommended to put the fork and knife down each time you put food in your mouth. Please bare in mind that fast eating should be avoided when dieting.
