What if you eat in a hurry?

Scientists say that a fast meal can lead to weight gain. If you do not chew food and literally swallow it, the brain simply does not have time to react. You will realize that you are exaggerating when it is already too late. Those who eat in a hurry are more likely to overeat.

Portion size also matters: research shows that the more food on your plate, the more you eat. Scientists themselves explain it this way: when we eat fast, we do not have time to be full and then we eat too much. And this is the first step to gaining weight. That is, the volume of the portion consumed depends on how fast you eat.


According to nutritionist Lydia Kvashina, a healthy meal should last at least 30-40 minutes. The fact is that the digestive process begins as soon as food enters the mouth. Saliva contains mucin, which contributes to the formation and adhesion of food bolus. Under the action of saliva enzymes in the oral cavity, the digestion of carbohydrates begins with their breakdown into dextrins – products of the partial breakdown of polysaccharides. This means that the more carefully you chew the food, the better it will be digested in the stomach.

In addition, during this process, hydrochloric acid begins to be produced, in the presence of which the digestion of proteins depends. Why is it important? The indigestible protein will not be broken down into the necessary amino acids and will go to the intestines unprocessed, causing there the process of decomposition and causing discomfort.

It is believed that food should be chewed up to 30 times, but it is better to focus on the taste buds. Once you stop feeling the taste of the food, you can proceed to swallowing. It is believed that one should leave the table a little hungry.

There is a healthy grain in it because the satiety signal comes about 20 minutes after eating. Therefore, there is always the possibility of overeating and this will result in weight, bloating, discomfort and extra pounds.

Why not eat on the go and chew fast?

The nutritionist notes that constant snacks on the go can lead to various diseases, such as:

  • heartburn;
  • gastritis;
  • ulcer;
  • violation of the intestinal microflora.


Not only that: an unformed food bolus can lead to injury to the lining of the stomach and intestines. But the consequences can be even more serious, such as diabetes and hormonal imbalance.

The human body was created in the course of evolution as something perfect, representing a chain of biochemical, mechanical and other reactions that occur one after the other. When we violate this provision, which has been perfected for millennia, it is impossible to predict the consequences.

This can be compared to the butterfly effect: today you swallow a chewing gum and after many years your joints ache. This may be because the damage caused the intestines to become permeable and substances that should not have been there entered the bloodstream. Think about it the next time you try a healthy wholemeal bread sandwich with chicken breast and salad.
