In medical world, diabetes is known more commonly by the name of diabetes mellitus. In simpler and day-to-day language, it is referred as diabetes. It is a group of metabolic diseases in which a person has high blood sugar, either because cells do not respond to the insulin that is produced, or the body does not produce enough insulin. In both the conditions, the body is not able to get enough amount of insulin to function properly.
This makes Darkes' story seem less plausible, said Dr. Matthias von Herrath, a professor of developmental immunology at La Jolla Institute in California, and an expert in type 1 diabetes. This type of claim is "earth-shattering," he said. "If it's not well corroborated, it's like your grandmother's rumor kitchen" — there's nothing backing the story. If there is a clinical record and the data are clear, the doctors should publish a case report, Von Herrath told Live Science. 
With all of the nutrition information available today about improving blood sugar, it can be a bit daunting to know which information is correct and which is not. It is so important to look to what science-based evidence and research says about the subject. But even more, we need this science to be translated into easy to understand advice so that we can actually incorporate it into our lives and benefit from it. This is the most important factor.
Is a prediabetes diagnosis serious? There has been significant debate around the term ‘prediabetes,’ and whether it should be considered cause for alarm. On the one hand, it serves as a risk factor for type 2 diabetes and a host of other complications, including heart disease, and ultimately prediabetes implies that a degree of metabolic problems have started to occur in the body. On the other hand, it places a diagnosis on many people who may never develop type 2 diabetes. Again, according to the CDC, 15-30% of those with prediabetes will develop type 2 diabetes within five years. However, a 2012 Lancet article cites 5-10% of those with prediabetes each year will also revert back to healthy blood sugars.
TCM does not offer a cure for diabetes, but instead aims to optimize the body’s ability to function normally. There is still a great need for more and better research on the efficacy and safety of both Chinese herbals, which are being used along with or in lieu of Western pharmaceuticals, and acupuncture in the care of diabetic patients. Patients, TCM practitioners, and physicians who choose to integrate the two forms of care must all recognize the importance of careful monitoring of blood glucose levels, as well as monitoring for potential side effects such as drug-herb interactions.
Known as gurmar, or “sugar destroyer,” in Aryuvedic medicine, Gymnema has consistently shown benefits in patients with diabetes. The most active part of Gymnema seems to be gymnemic acids, and many products list the percentage each capsule contains. Analyses of the herb for diabetes have shown it may be helpful in lowering high blood sugar levels. It can delay glucose absorption from the intestine. It was shown to regenerate pancreatic tissues, allowing more insulin to be produced, and help regulate insulin secretion. It also increases the utilization of glucose by the cell, reducing insulin resistance and decreasing appetite, especially for sweets. I usually use it in capsules, or in liquid form in some patients. Due to Gymnema having a very similar shape to glucose, it can fit into the taste bud receptors for sugar; it thus has unbelievable power to actually prevent the taste of sweets in the mouth for up to 1.5 hours. When I have a patient who is still struggling to not eat cake and cookies and so forth at parties or celebrations (or just in general), I will give her a tincture of Gymnema sylvestre. This is one of my favorite herbs for diabetes. In capsule form doses of 400 to 2,400 mg a day are recommended.

The above two rules are the only dietary rules you need to maintain ideal weight for the rest of your life, assuming you apply common sense and avoid extremes. The diet works by building in regular periods of insulin relief, keeping your body from becoming resistant to insulin. Following these two rules, you will maintain your weight and health by never entering the vicious cycle of increasing insulin resistance.
