Because the drugs listed above act in different ways to lower blood glucose levels, they may be used together. For example, a biguanide and a sulfonylurea may be used together. Many combinations can be used. Though taking more than one drug can be more costly and can increase the risk of side effects, combining oral medications can improve blood glucose control when taking only a single pill does not have the desired effects. Switching from one single pill to another is not as effective as adding another type of diabetes medicine.
"Yes, it's a frustrating case," Darkes told Live Science in an email. "But the doctors have to be as accurate as they can be with what's happened, so they've given a 2-year time scale for completed type 1 reversal." Darkes explained that if he can go without insulin injections for two years, his doctors will be 100 percent sure his diabetes is gone.
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.
Scientists are trying to figure out how to transplant islet cells and then protect them from the patient’s immune system so that long-term immunosuppressive medications aren’t required. Micro encapsulation is an approach scientists are testing to find out if a special coating to the transplanted islets can help the patient avoid rejection of those islets. These coatings let in nutrients to nourish the cells but prevent your body’s immune system from attacking them.
You should have no more than three of these “feeding times” per day. The reason limiting the number and duration of your meal times is so important has to do with staying out of the vicious cycle of increasing insulin resistance. To get smart on insulin resistance — the cause of both type 2 diabetes and obesity — read Dr. Jason Fung’s book, The Obesity Code: Unlocking the Secrets of Weight Loss, or watch his free lecture on YouTube.
