If you don't eat foods rich in carbohydrates, it may cause insufficient supply of carbohydrates in your body. In the long run, hypoglycemia will come uninvited. Hypoglycemia is very harmful to human body, especially to nervous system.

Carbohydrate is the most important energy provider during exercise, and the intensity of exercise also depends on the participation of carbohydrate. Carbohydrates can't be stored in the body as much as protein and fat. Once you don't get enough supplements, you will be lacking, especially in the process of a lot of exercise and strong physical labor. If you lack carbohydrates during exercise, your muscles will show fatigue, weakness and other discomfort.

In addition, glucose is the most important nutrient in the brain, but all the glucose needed by the brain comes from blood. If carbohydrates are not supplemented in time, it will lead to insufficient glucose supply and seriously affect brain activity. Slow response, memory loss and cognitive impairment are all the consequences of glucose deficiency in the brain.
