First of all, it is a direct source of energy for the brain and nerves. Only glucose can be directly used as a direct energy source by the brain, nerves and red blood cells, especially the brain is more dependent on sugar. When glucose is insufficient, people are prone to inattention, memory loss, and even discomfort such as dizziness.
Secondly, it is the source of maintaining body temperature. After sugar enters the human body, it is immediately absorbed into the blood in the small intestine, and then transported to all parts of the body by red blood cells, which are used to participate in various biochemical reactions in cells, provide heat for the human body, ensure normal body temperature and maintain human physiological activities.
Finally, it is the foundation of sports and activities. Sugar is the most basic energy source for human activities. It can not only be directly absorbed and utilized by human body, but also be temporarily stored in the form of glycogen by muscles and liver. When there is high-intensity exercise, these glycogen will be released to support human movement.
If you want to lose weight, you can skip meals-this theory is very unrealistic in the process of losing weight. The human body is a precise instrument, and the relationship between various systems is by no means a relationship that can be realized without this. For most people who lose weight, carbohydrates are an enemy. However, without carbohydrates, it is difficult to lose weight, which is also the truth of the sentence "How to lose weight if you don't have enough to eat".
We usually eat rice, bread, pasta and so on. As the staple food in our daily life. Matsuda Zaomiao, an associate professor in the Nutrition Research Office of Japanese Women's Nutrition University, pointed out: "People who lose weight are not advised to completely isolate carbohydrates, because carbohydrates are an important fire of fat metabolism. Without this fire, fat can't be completely burned and weight loss can't be successful. " In other words, glucose is needed as a catalyst for fat metabolism. If glucose is lacking, the decomposition reaction of fat will be greatly hindered, which is not conducive to weight loss.
In addition, if the human body lacks carbohydrate intake for a long time, the human body will automatically decompose protein to supply glucose as an energy source. Protein is an important part of the body, and it also constitutes the existence of biological enzymes. The loss of protein may cause muscle loss, further reduce the metabolic level, which is not conducive to weight loss, and may even be harmful to health. Therefore, normal intake of carbohydrates, and strengthening exercise, so that glucose can fully participate in the process of fat metabolism, in order to effectively lose weight.
Eating carbohydrates also requires skill.
Although carbohydrate is an indispensable and important substance, it has been known from the attitude of limiting carbohydrate intake in the weight loss community that the harm caused by excessive carbohydrate intake is far greater than that caused by insufficient carbohydrate intake. Excessive intake of carbohydrates may lead to the accumulation of visceral and subcutaneous fat, especially refined carbohydrates are more likely to cause a sharp rise in blood sugar, and insulin is secreted in large quantities, which further stimulates excess energy to accumulate into fat, which is particularly unfavorable for weight loss.
Therefore, the intake of carbohydrates should match the thickness, and coarse grains such as brown rice and black rice should be eaten as much as possible, or mixed with flour and rice, not just refined carbohydrates.
In addition, many people like to use dessert or bread instead of rice, but it is easy to cause excessive intake of refined carbohydrates, while protein, dietary fiber, vitamins and minerals are easy to lack. Therefore, people who lose weight should fully keep the habit of regularly eating three meals, and each meal has carbohydrates, but don't indulge themselves to eat more carbohydrates, consciously increase the intake of nutrients such as protein, minerals, vitamins and dietary fiber, and at the same time increase exercise and strengthen fat consumption.
