Type-two diabetes is preceded by pre diabetes, often for a period of ten years but sometimes for only three years. During this time, the pancreas produces abnormally high levels of insulin in an attempt to contend with blood glucose levels that are too high. If overeating continues long enough, the pancreas becomes fatty and clogged. Thereafter it fails to produce sufficient amounts of insulin.
During pre diabetes, insulin resistance may also occur. It is a condition in which cells fail to respond normally to insulin. Cells resistant to the insulin and are unable to use it effectively. Exercise is very important in addressing insulin insensitivity as an abstract describes here
The link below reports research done by Professor Roy Taylor of Newcastle University and presented at an American Diabetes Association conference. It shows that an extremely low-calorie diet prompts the body to remove the fat clogging the pancreas, and that it is this clogging that prevents the pancreas from delivering insulin. A 600 calorie diet for three months was used to remove fat from the pancreas.
Low-calorie diet offers hope of cure for type 2 diabetes
Here is a link to some of his continuing research:

A 600 calorie diet for three months will often cure recently diagnosed patients, but this is a brutal regimen that is designed for the timely proof that medical researchers desire. A permanent and sustainable diet of the right kind can be just as effective, and is less likely to yield only temporary results.
I cured myself of type-two diabetes through vigorous exercise and an effective diet. I lost 115 pounds. I made use of regular blood tests to discover the effects of various foods, and also decided to eat only the food that was widely available prior to 10,000 years ago. This was when the domestication of plants and animals began.
First to be excluded from my diet was refined-sugar products such as candy, cake, cookies, pastry, ice cream, sherbet, jello, pudding, fruit pies, doughnuts, fruit juices, milk shakes, soda, and alcohol. If you never eat sugar at all, you will soon stop wanting it.
The day that I was diagnosed with type-two diabetes, I had a blood clot removed. Because of that, I was prescribed a blood thinner that required a weekly blood test to regulate the amount of blood thinner I would take. This gave me an opportunity to experiment. I became suspicious of cheese. It was certainly a modern food. I ate a slice or two of cheese every day for a week between blood tests. Then, I would have no cheese for a week until the next blood test. I would alternate cheese weeks with non-cheese weeks for at least two months. I found that cheese seemed to make me need more blood thinner. I would like to see a better controlled experiment conducted, but, in any case, I quit eating cheese.
I eventually quit all dairy products and eggs. They had little usage among adults before the domestication of animals. Butter and margarine are, of course, too modern.
In Roman times, government farms produced a lot of wheat for their armies, but centuries before, grains were not produced in gardens, much less produced or found in large quantities. There were no fields of single-grain crops.
Grains are such a dense store of fuel that only people who work as hard as coal miners can stay thin while using them as a major source of sustenance. I excluded wheat, rye, corn, rice, and all grains, along with bread, toast, pasta, breakfast cereals, snack chips, crackers, and popcorn. For the same reason, I also excluded all high-carbohydrate vegetables such as potatoes and lentils. By the way, the potato was discovered by Europeans only by the 1500's.
I stopped consuming beef, pork, lamb, and processed meats such as bologna, pepperoni, salami, hot dogs, and sausage. For the last 10,000 years, beef, pork, and lamb have been traded on the basis of weight. The selection and breeding of the live stock caused the meat to become marbled with fat. After loosing 70 pounds, I still had high cholesterol and took medications for it. I was able to quit these medications only after excluding from my diet beef, pork, lamb, and the products made from them. Of course, I have excluded bacon which is a particularly fatty cut of pork.
This might seem like it doesn't leave much to eat, but it does.
I drink mostly distilled water. Besides water, my diet currently consists of nuts, chicken, turkey, mushrooms, tomatoes, tomato juice, tomato paste, spaghetti sauce (without pasta), carrots, green beans, beets, artichokes, green peppers, cucumbers, zucchini, turnips, lettuce, asparagus, cauliflower, onions, Italian salad dressing, pickles, olives,
mustard, cinnamon, salt, basil, thyme, oregano, mint, garlic, canola oil, green tea, and black coffee. I feel no deprivation.
The only fruit I eat routinely is tomato. The seeds of high-sugar fruits were spread by birds all over the world. This had very little to do with humanity until modern times. If you are convinced that there is a health benefit in some component of high-sugar fruit, I would recommend that you buy the extract and leave the sugar in the store.
When hunger strikes between meals, it just takes a few unsalted mixed nuts to stops my hunger. This does not add much to my weight. Peanut butter and almond butter worked less well for this purpose.
Weight monitoring and blood tests seem essential. The foregoing diet has been described only qualitatively. Activity level, age, and health constraints need to be taken into account in order to decide on the balance of food items that is best for you. Chicken, turkey, mushrooms, nuts, tomatoes, beets, green peppers, lettuce, artichokes, olives, and onions outweigh the remainder of what I eat. I exclude all seafood because it contains cadmium. The bottom of the food chain in the ocean has come to depend upon cadmium. See this article.
Your blood sugar is under control if your long term A1C blood test is between 6.1 and 6.9. Lower numbers are better. My A1C is 4.8. Soon after my diagnosis, I was taking 90 units of insulin per day. Now I need none.
The hardest part of the diet is dealing with people. We have about one holiday a month. Cookies, cupcakes, candy, apple pie, pastry, ice cream, and many other forms of sugar are brought out as an obligation of some sort. The trick is to keep your friends without eating their food.
