Glucose acts as fuel in the body. It is the main source of energy for cells, and the ability of cells to function normally is largely determined by their ability to absorb glucose.. It enters the body with food. Food is broken down in the gastrointestinal tract into molecules, after which glucose and some other breakdown products are absorbed, and undigested residues (slags) are excreted through the excretory system..

In order for glucose to be absorbed in the body, some cells need a hormone from the pancreas called insulin.. Insulin is usually compared to the key that opens the door to the cell for glucose, and without which it will not be able to penetrate there.. If there is no insulin, most of the glucose remains in the blood in an unassimilated form, while the cells starve and weaken, and then die of hunger.. This condition is called diabetes..

Some body cells are non-insulin dependent. This means that they absorb glucose directly, without insulin.. Brain tissues, red blood cells and muscles are made up of insulin-independent cells - this is why, with insufficient intake of glucose into the body (that is, during hunger), a person quite soon begins to experience difficulties with mental activity, becomes anemic and weak.

However, much more often modern people are faced not with a lack, but with an excess intake of glucose into the body as a result of overeating.. Excess glucose is converted into glycogen, a kind of " Most glycogen is stored in the liver, a smaller part is stored in skeletal muscles. If a person does not take food for a long time, the process of splitting glycogen in the liver and muscles starts, and the tissues receive the necessary glucose..

If there is so much glucose in the body that it can no longer be used either for tissue needs or utilized in glycogen depots, fat is formed.. Adipose tissue is also a “warehouse”, but it is much more difficult for the body to extract glucose from fat than from glycogen, this process itself requires energy, which is why losing weight is so difficult. If you need to break down fat, then the presence of... right, glucose is desirable, to ensure energy consumption.

This explains the fact that diets for weight loss should include carbohydrates, but not any, but hard to digest.. They break down slowly, and glucose enters the body in small amounts, which are immediately used to meet the needs of cells.. Easily digestible carbohydrates throw an excessive amount of glucose into the blood at once, there is so much of it that it must immediately be disposed of in fat depots.. Thus, glucose in the body is essential, but it is necessary to provide the body with glucose wisely..
