Depending on the severity of diabetes, an individual can keep control on his/her disease using diet alone, diet & oral hypoglycemic drugs, and diet & insulin. While a mild diabetic can practice disease control with diet alone, a severe diabetic might need to practice diet control along with insulin administration. Whatever the method of controlling diabetes, routine and reliability should be strictly pursued. A person suffering from diabetes should have limited amount of carbohydrates and fats along with moderate amount of protein in the diet. High-fiber diet like vegetables, whole wheat products, oats, whole legumes prove to be more beneficial. Let us have a look at what all should be had and what all should be avoided.

Others have also changed their lives through the diet. Carlos Cervantes, 53 and from the US, was at death's door when he tried it. He weighed 120kg, suffered a heart attack in spring 2011, his eyesight and kidneys were failing and he faced having an infected toe amputated. He even had fungus growing out of his ears, feeding on his ultra-high blood sugar levels. But after seeing a TV report on the Newcastle research, he started eating only 600 calories a day, replacing the supplements with not just vegetables but fruit, lean chicken, turkey, occasional bread and a daily milkshake. Two months later he had lost 40kg and 18 months later he is still free of his type  2 diabetes.
Milk thistle is an herb that has been used since ancient times for many different ailments and is considered a tonic for the liver. The most studied extract from milk thistle is called silymarin, which is a compound that has antioxidant and anti-inflammatory properties. It is these properties that may make milk thistle a great herb for people with diabetes.
There are numerous studies of botanical medicines and herbs for diabetes that speak to the effectiveness of natural and home remedies for diabetes. I have listed the most useful herbs with the most documented benefits. A patient does not need to take one hundred bottles a day of everything out on the market, but rather it is important to focus on a few botanicals backed by the most impressive studies and the best clinical evidence. The botanicals listed below are safe and effective.

Whole-body insulin resistance is the earliest predictor of type 2 diabetes onset, and this mainly reflects muscle insulin resistance (26). However, careful separation of the contributions of muscle and liver have shown that early improvement in control of fasting plasma glucose level is associated only with improvement in liver insulin sensitivity (20,21). It is clear that the resumption of normal or near-normal diurnal blood glucose control does not require improvement in muscle insulin sensitivity. Although this finding may at first appear surprising, it is supported by a wide range of earlier observations. Mice totally lacking in skeletal muscle insulin receptors do not develop diabetes (27). Humans who have the PPP1R3A genetic variant of muscle glycogen synthase cannot store glycogen in muscle after meals but are not necessarily hyperglycemic (28). Many normoglycemic individuals maintain normal blood glucose levels with a degree of muscle insulin resistance identical to those with type 2 diabetes (29).
The way you take insulin may depend on your lifestyle, insurance plan, and preferences. You may decide that needles are not for you and prefer a different method. Talk with your doctor about the options and which is best for you. Most people with diabetes use a needle and syringe, pen, or insulin pump. Inhalers, injection ports, and jet injectors are less common.
About Diabetes, Type 2:  Type 2 diabetes is characterized by "insulin resistance" as body cells do not respond appropriately when insulin is present. This is a more complex problem than type 1, but is sometimes easier to treat, since insulin is still produced, especially in the initial years. Type 2 may go unnoticed for years in a patient before diagnosis, since the symptoms are typically milder (no ketoacidosis) and can be sporadic. However, severe complications can result from unnoticed type 2 diabetes, including renal failure, and coronary artery disease. Type 2 diabetes was formerly known by a variety of partially misleading names, including "adult-onset diabetes", "obesity-related diabetes", "insulin-resistant diabetes", or "non-insulin-dependent diabetes" (NIDDM). It may be caused by a number of diseases, such as hemochromatosis and polycystic ovary syndrome, and can also be caused by certain types of medications (e.g. long-term steroid use). About 90-95% of all North American cases of diabetes are type 2, and about 20% of the population over the age of 65 is a type 2 diabetic. The fraction of type 2 diabetics in other parts of the world varies substantially, almost certainly for environmental and lifestyle reasons. There is also a strong inheritable genetic connection in type 2 diabetes: having relatives (especially first degree) with type 2 is a considerable risk factor for developing type 2 diabetes. The majority of patients with type 2 diabetes mellitus are obese - chronic obesity leads to increased insulin resistance that can develop into diabetes, most likely because adipose tissue is a (recently identified) source of chemical signals (hormones and cytokines).
Researchers are discovering more about the causes of type 2 diabetes but as yet there are no clear avenues for a cure. With this said, there has been success in reversing the development of type 2 diabetes. Methods which result in a significant loss of weight have been successful in helping people to control blood glucose levels and have allowed some people to come off their diabetic medication. Methods such as bariatric surgery and very low calorie diets have been successful in allowing patients to reduce dependency on medication.
"You only need 10 percent of your beta cells to supply sufficient insulin," Roep said. He said there have been a couple of rare cases where a patient had typical type 1 diabetes but could go through long periods without insulin injections. "Insulin needs can be a moving target, and if you have a lifestyle change it's very plausible that you have a lesser need for insulin, and you can deal with [diabetes] with the beta cells you have," Roep said.
In 2003, ephedrine -- also known as ma huang -- became the first herbal stimulant ever banned by the FDA. It was a popular component of over-the-counter weight loss drugs. Ephedrine had some benefits, but it could cause far more harm, especially in high doses: insomnia (difficulty falling and staying asleep), high blood pressure, glaucoma, and urinary retention. This herbal supplement has also been associated with numerous cases of stroke.
Trick (most important): Go for longer periods of time without eating (yes, yes, fasting). Consume water only for days or weeks at a time. Your fat will literally dissolve away, and with it your type 2 diabetes and other ailments. The definitive book here is Dr. Joel Fuhrman’s book, Fasting and Eating for Health: A Medical Doctor’s Program for Conquering Disease. I highly recommend it; if you’re skeptical, read the 200+ testimonial comments on Amazon. I and at least 20 of my friends have tried fasts lasting days to weeks. It works, and it is amazing.
