Secondly, from the perspective of modern nutrition, the time and frequency of three meals a day are mainly arranged according to the physiological needs of the body, especially the activity law of the digestive system, and taking into account the daily life, work or study. For example, the interval between meals is mainly determined by the function of the digestive system and the time when food has not been emptied. Generally speaking, the emptying time of mixed food in the stomach is 4-5 hours, so the interval between meals is 4.
What will happen to your body if you don't eat breakfast and dinner?
First of all, generally speaking, you need to work, work and study in the morning. If you don't eat breakfast, it will definitely reduce the efficiency of work, study and work in the morning. After all, without energy supplement, doing things will definitely be boring. Although there is little strength now, for people who do mental work, without the supply of blood sugar, their brains will be slow and inattentive.
Secondly, if you don't eat breakfast and dinner, the lunch time will be too long from the dinner the day before or the breakfast the next day, which can be said to be as long as seventeen or eight hours. This will make the stomach empty for too long, and the stomach will continue to secrete gastric acid without food for a long time, which will aggravate the damage to the gastric mucosa. Secondly, if there is no food in the stomach for a long time, the movement of the stomach, that is, the contraction and relaxation ability of the stomach will be weakened. Over time, gastric motility will decrease and gastrointestinal peristalsis will slow down.
In this way, three meals a day is obviously more suitable and scientific than two meals a day! In addition, think about it, if you eat one meal, it is obvious that people are so hungry that you won't eat three meals. If it is good to increase the number of meals, it is good for special people, such as patients with stomach diseases and diabetics, as long as conditions permit.
Of course, if you have dinner, it is ok to skip a meal occasionally, for example, if you eat too much in the morning (it is best not to overeat) or skip eating for two days a week, let your stomach empty properly. Needless to say, breakfast must be eaten. Breakfast plays a vital role in nutrient intake. Studies have found that skipping breakfast is more likely to lead to obesity.
