The first step is to eliminate all sugar and refined starches from your diet. Sugar has no nutritional value and can therefore be eliminated. Starches are simply long chains of sugars. Highly refined starches such as flour or white rice are quickly broken down by digestion into glucose. This is quickly absorbed into the blood and raises blood sugar. For example, eating white bread increases blood sugars very quickly.
This section deals only with approaches for curing the underlying condition of diabetes type 1, by enabling the body to endogenously, in vivo, produce insulin in response to the level of blood glucose. It does not cover other approaches, such as, for instance, closed-loop integrated glucometer/insulin pump products, which could potentially increase the quality-of-life for some who have diabetes type 1, and may by some be termed "artificial pancreas".
Type 2 diabetes is a condition that is characterised by chronically elevated blood sugar levels. However, the main cause as well as the driver for this condition is something called Insulin Resistance. When you eat certain foods, particularly refined carbohydrates, that food is converted to sugar inside your body. Your body’s way of dealing with this sugar is to produce a hormone called insulin. Insulin moves the sugar inside your cells so that it can be used for energy. Sounds great, right?
Sugars raise insulin levels, and over extended periods of time, damage the pancreas and cause insulin resistance, a precursor for diabetes. Fructose is the top offender in the sugar world, as it is recognized as a toxin the body and has no proven benefit to the body. Fructose is immediately taken to the liver, where it must be processed, and some doctors now suggest that this may be a large factor in development of fatty liver disease. Excess sugar in the bloodstream also increases the release of cortisol and adrenaline (more on those in a minute), slows the immune response, decreases necessary Leptin levels and promotes fat storage. There are various types of sugar and sweeteners, and while all should be limited, some are worse than others:
The diabetes market is expected to reach a massively big €86Bn by 2025 combining both type 1 (€32Bn) and type 2 (€54Bn) treatments, and we can expect all sort of revolutionary technologies to come forward and claim their market share. Researchers are already speculating about microchips that can diagnose diabetes type 1 before the symptoms appear or nanorobots traveling in the bloodstream while they measure glucose and deliver insulin.

Patients with type 1 diabetes mellitus require direct injection of insulin as their bodies cannot produce enough (or even any) insulin. As of 2010, there is no other clinically available form of insulin administration other than injection for patients with type 1: injection can be done by insulin pump, by jet injector, or any of several forms of hypodermic needle. Non-injective methods of insulin administration have been unattainable as the insulin protein breaks down in the digestive tract. There are several insulin application mechanisms under experimental development as of 2004, including a capsule that passes to the liver and delivers insulin into the bloodstream.[39] There have also been proposed vaccines for type I using glutamic acid decarboxylase (GAD), but these are currently not being tested by the pharmaceutical companies that have sublicensed the patents to them.
If you are interested in trying a natural treatment in addition to standard treatment, be sure do so only under the close supervision of your physician. If diabetes is not properly controlled, the consequences can be life-threatening. Also, inform your physician about any herbs, supplements, or natural treatments you are using, because some may interact with the medications you are taking and result in hypoglycemia unless properly coordinated. 
Also called weight-loss surgery or metabolic surgery, bariatric surgery may help some people with obesity and type 2 diabetes lose a large amount of weight and regain normal blood glucose levels. Some people with diabetes may no longer need their diabetes medicine after bariatric surgery. Whether and for how long blood glucose levels improve seems to vary by the patient, type of weight-loss surgery, and amount of weight the person loses. Other factors include how long someone has had diabetes and whether or not the person uses insulin.1
8. Get your protein from vegetable sources, fish, and dairy: Plant-based proteins have a balanced nutritional profile (providing fiber, fat, and protein) and are low in saturated fats. Some saturated fats, like those that are heavily processed or from unhealthy animals, can be dangerous, as they raise cholesterol levels and contribute to heart disease. Dairy from pastured animals (such as yogurt) that is low in sugar provides protein, carbohydrates, and beneficial probiotics, and non-mercury contaminated, wild caught fish is a great source of protein that is low in saturated fat and high in amino acids and fatty acids like Omega-3.
Eating right and exercising more often is good for everyone. But it's especially important for people with type 2 diabetes. When people put on too much body fat, it's because they're eating more calories than they use each day. The body stores that extra energy in fat cells. Over time, gaining pounds of extra fat can lead to obesity and diseases related to obesity, like type 2 diabetes.
Try to keep carbohydrate amounts stable across the day (some choose lower carbohydrate targets), stand more and sit less and include activities that increase the heart rate and also strength based activities most days across the week. Think about the amount of stress you experience to see how it is increasing your blood glucose levels. If you smoke – stop because it is speeding up the damage to your blood vessels. If you drink alcohol, limit how much you drink.
Conventional: A dietary pattern that includes carbohydrates from fruits, vegetables, whole grains, legumes, and low-fat milk is encouraged for good health. Carbohydrate intake should be monitored using carbohydrate counting or experienced-based estimation. The Recommended Dietary Allowance for digestible carbohydrates is 130 g/day, which will provide a sufficient amount of glucose needed to fuel the central nervous system without reliance on glucose production from protein or fat. Using foods with a low glycemic index that are rich in fiber and other important nutrients is encouraged.

“Whether it be the patient saying for the fifth time ‘I will start watching my diet and start exercising,’ or a physician saying ‘the A1c is close to goal and I don’t really want to add yet another medication and copay, we will wait and see what happens in another 3 months,’ the end result is lack of intensification and A1c goal attainment,” Pantalone said.
When this happens for a period of time, the cells start to become resistant to the presence of insulin, causing a vicious cycle. The body then releases even more insulin, trying desperately to get the cells to uptake the toxic glucose. The presence of excess insulin in the bloodstream is also toxic and further damages the receptors on these cells. Eventually, the insulin allows the glucose access to your fat cells to get it out of the bloodstream. In other words- Fat isn’t stored as fat in the body- Sugar (from carbohydrates) is stored as fat!

If the rapid changes in metabolism following bariatric surgery are a consequence of the sudden change in calorie balance, the defects in both insulin secretion and hepatic insulin sensitivity of type 2 diabetes should be correctable by change in diet alone. To test this hypothesis, a group of people with type 2 diabetes were studied before and during a 600 kcal/day diet (21). Within 7 days, liver fat decreased by 30%, becoming similar to that of the control group, and hepatic insulin sensitivity normalized (Fig. 2). The close association between liver fat content and hepatic glucose production had previously been established (20,22,23). Plasma glucose normalized by day 7 of the diet.
Like the sulfonylureas, meglitinides is a class of drugs that work by promoting insulin secretion from the pancreas. Unlike the sulfonylureas, which last longer in the body, repaglinide (Prandin) and nateglinide (Starlix) are very short acting, with peak effects within one hour. For this reason, they are given up to three times a day just before meals.
