After all, rice, noodles, steamed bread and so on. , is the staple food we eat every day, belonging to carbohydrates. The purpose of eating them is to make yourself full of energy and provide a feeling of fullness. One gram of carbohydrate has 4000 calories, which is the most convenient energy source. In a word, carbohydrates are the main energy to maintain the normal operation of the brain, especially glucose, which is an essential nutrient to maintain the normal function of the brain. This is why eating some sweets will make you feel happy, and sometimes if you don't eat enough carbohydrates, it's easy to feel uneasy. When carbohydrate intake is insufficient, the human body will use other nutrients for energy supply, such as: protein; The process of decomposing protein's "sugar making" and protein is called gluconeogenesis. Protein is an important part of muscle, which is why when you choose to go on a diet to lose weight, you consume muscle instead of fat. The lack of protein is harmful to human health, and the most obvious is the decline of immunity.
Therefore, a certain amount of carbohydrates can prevent the decomposition of protein and save the utilization of protein. Basic nutrition knowledge of fitness-carbohydrates, correctly understand carbohydrates and other nutrients. In addition, if your carbohydrate intake is in a little state for a long time, your body will not only use protein as the energy source, but also use fat as the energy source, and the fat will be decomposed into ketone bodies for energy supply, which is the ketogenic diet. In addition, the insulin in the body will be at a very low level, which is very unfavorable for diabetic patients. Human cells also contain carbohydrates with a content of 2%~ 10%.
Carbohydrate is also a part of cell tissue. The basic nutrition knowledge of fitness-carbohydrates, correctly understand the classification of carbohydrates and other nutrients and carbohydrates. According to the digestibility and glycemic index, carbohydrates are divided into complex carbohydrates and simple carbohydrates. Complex carbohydrates: slow digestion and absorption, slow glycemic index, strong satiety and lasting energy. Simple carbohydrates: fast digestion and absorption, fast glycemic index and short-term lasting energy.
Generally speaking, the carbohydrates we choose to lose weight should be foods with relatively low GI value, which will slow down the speed of blood sugar increase after intake and be more conducive to weight loss. But the GI value is not only the food itself, but also the way you cook. Therefore, when choosing food, we should not only look at the GI value of the food itself, but also pay attention to cooking skills, side dishes and so on.
