The problem of losing weight without dinner is still controversial. Some people think that skipping dinner is a healthy behavior, because Buddhists have the tradition of "skipping lunch", and some emperors in ancient China also had the habit of "skipping lunch" in order to live forever. Modern medicine tends to think that skipping dinner is a very bad habit.
Generally speaking, it takes about four or five hours for food to be digested in the stomach. If we don't have dinner, the food at noon will be digested around 6 pm. However, after people fall asleep, the activity of the stomach and intestines will decrease. This will lead to a long time interval from the end of lunch to sleep, during which people's stomachs are still active, but less active than when there is food in their stomachs. At this time, the stomach will still secrete gastric acid. If you don't eat dinner, the acid in your stomach may do harm to your stomach. If you don't eat dinner for a long time, you will get stomach trouble over time, and even lead to serious consequences of gastric cancer. Therefore, the mainstream in the field of nutrition believes that dinner must be eaten.
Sugar is the main energy source of the body, but the storage of sugar in the body is very small. There is about 400g of sugar in the adult body, which can only last for 24 hours at most and is completely consumed. This is actually very dangerous for the body.
If you don't eat dinner, lunch and breakfast will be more than ten hours apart the next day, and there is not much sugar left, which has already begun to decompose the energy provided by protein. But in this process, in fact, the consumption of fat has not increased much, because fat belongs to something that is particularly difficult to consume in the body, so it cannot be used for emergency. Moreover, when there is not much sugar left, we can't help but want to eat more, especially foods with high sugar and fat, and as a result, we eat more. In addition, due to the consumption of protein, the speed of human fat metabolism slows down, which is not conducive to fat consumption. So the result of not eating dinner can only deceive weighing scale, in fact, the body fat has not decreased much.
