There is no doubt that the human body is capable of self-repair and that residual islet function still exists in most patients with any type of diabetes. This is because most diabetes, especially type 2 diabetes, has improved islet function after the relief of hyperglycemia with insulin, for example. At the same time, such a situation can be seen with exercise, liposuction and gastric reversal surgery, and many other methods that reduce body fat and its total metabolism. This is because the process of fat metabolism prevents blood glucose from entering the cells, reduces the efficiency of insulin work, and leads to initial hyperfunction of the pancreas, followed by fatigue failure. Thus, it is both the main cause of type 2 diabetes and a superimposed factor for various other causes. For example, diabetes is not only high after obesity and hyperlipidemia, but also in people with other bad habits that lead to increased frequency of fat metabolism, such as skipping breakfast and drinking a lot of alcohol. At the same time, the 30-year high incidence of diabetes in China coincides with the country’s economic development and the improvement of people’s living conditions, and the map and its development lines have always been highly consistent with the high incidence of diabetes. The most important factor associated with the occurrence of diabetes is the large increase of meat, eggs, milk and fried oil in the diet and the large decrease of cereals or food sugars. At the same time, with the advent of computers and television, the work environment has become increasingly mechanized, while the intensity of labor or exercise has been significantly reduced. That is: one side of the energy intake is greatly increased, the other side of the energy expenditure is greatly reduced, and the energy savings in the body can only synthesize fat. Because, meat, eggs and milk not only only high protein, while there are calories far more than protein and sugar more than double the variety of saturated fat, and milk and many parts of lean meat protein without more fat. Frying oil although more unsaturated fatty acids. That is: in the process of human energy metabolism is relatively saturated fat is not easy to store, but calorie generation is exactly the same as its. That is: after being converted into energy by the body, can not be consumed will also synthesize saturated fat, and direct intake of fatty meat is no different. In addition, since fat is almost the only way to store energy in the body that cannot be consumed, it is also synthesized as fat, regardless of whether the energy comes from sugar or excess protein. Therefore, there are also a significant number of patients who come from a sweet tooth and sugary ingredients, and there are also patients whose dietary energy does not change at all, but only develops due to exercise, i.e.: reduced energy expenditure and its output. Therefore, although some people advocate the increase of coarse grains, but it does not solve the problem. Therefore, the guidelines for the prevention and treatment of diabetes around the world are based on the principle of dietary energy to meet the ideal body weight, reducing the total amount of fat and its saturated fat energy ratio. At the same time, to protect the basic needs of protein sugar. Because, sugars and proteins have their own functions, only in the conversion of energy can not be consumed conditions, will be synthesized or turned into saturated fat. However, since the diet is in a state of loss of control. Therefore, although the treatment method has long been insulin to break down blood sugar directly, α-glucosidase inhibitor to inhibit sugar absorption, metformin and other methods to promote metabolism around blood sugar to reduce the burden on the pancreas, and also exercise, liposuction and gastric flip surgery to reduce fat storage and its total metabolism, but the effect cannot survive. Because, there is no technology to replace the patient to eat, so it can only be used passively and its help metabolism. That is: under the condition of uncontrolled diet, insulin helps to lower sugar effectively, but cannot stop its excessive inability to consume synthetic fat; exercise, liposuction and gastric reversal surgery are effective for weight loss, but cannot resist the destruction of continued dietary energy and excessive fat interference easily; α-glucosidase inhibitors inhibit sugar absorption, and biguanide hypoglycemic drugs promote blood sugar metabolism in peripheral tissues to alleviate pancreatic negative, but cannot control its cause of sugar energy absolute and relative Insufficient, causing fat to replace sugar to maintain life into the blood, fat glycerol base involved in allogenic blood glucose, the process of releasing low density and free fat to the blood. Thus, it can aggravate both insulin insensitivity and its reduction of its efficiency etiology, but also lead to more fat passing through the blood, process accelerating complications. That is, although excessive dietary energy and fat intake and obesity are only some of the causes of type 2 diabetes, they can lead to the total incurability of any type of diabetes. Therefore, helping patients to actually achieve their diabetic treatment diet management goals can naturally reduce the burden on the pancreas, promote the body’s natural repair, and substantially reduce the need for medication. This not only provides a new approach to diabetes treatment, but also offers the possibility of overcoming incurability for those with surviving islet function, and maximizes the protection of residual islet function.
