Together with evidence of normalization of insulin secretion after bariatric surgery (84), insights into the behavior of the liver and pancreas during hypocaloric dieting lead to a hypothesis of the etiology and pathogenesis of type 2 diabetes (Fig. 6): The accumulation of fat in liver and secondarily in the pancreas will lead to self-reinforcing cycles that interact to bring about type 2 diabetes. Fatty liver leads to impaired fasting glucose metabolism and increases export of VLDL triacylglycerol (85), which increases fat delivery to all tissues, including the islets. The liver and pancreas cycles drive onward after diagnosis with steadily decreasing β-cell function. However, of note, observations of the reversal of type 2 diabetes confirm that if the primary influence of positive calorie balance is removed, then the processes are reversible (21).
You also might hear about alternative treatments for diabetes, such as herbal remedies and vitamin or mineral supplements. These practices can be risky, especially when people stop following the treatment plan their doctor has given them. So get the facts by talking to your diabetes health care team. They keep track of the latest research developments, and will introduce new products as they become available.
Physical activity is an important part of controlling diabetes and preventing complications such as heart disease and high blood pressure. "We know that exercise is a very effective way to help bring blood sugars under control for someone with type 2 diabetes," says Kenneth Snow, M.D., Acting Chief, Adult Diabetes, Joslin Clinic. Try for 30 minutes of moderate exercise, like brisk walking, on most days. Joslin's Why WAIT? and Easy Start exercise programs are great resources for developing a safe weight loss program.
Imagine that you hide your kitchen garbage under the rug instead throwing it outside in the trash. You can’t see it, so you can pretend your house is clean. When there’s no more room underneath the rug, you throw the garbage into your bedroom, and bathroom, too. Anywhere where you don’t have to see it. Eventually, it begins to smell. Really, really bad.
The earliest predictor of the development of type 2 diabetes is low insulin sensitivity in skeletal muscle, but it is important to recognize that this is not a distinct abnormality but rather part of the wide range expressed in the population. Those people in whom diabetes will develop simply have insulin sensitivity, mainly in the lowest population quartile (29). In prediabetic individuals, raised plasma insulin levels compensate and allow normal plasma glucose control. However, because the process of de novo lipogenesis is stimulated by higher insulin levels (38), the scene is set for hepatic fat accumulation. Excess fat deposition in the liver is present before the onset of classical type 2 diabetes (43,74–76), and in established type 2 diabetes, liver fat is supranormal (20). When ultrasound rather than magnetic resonance imaging is used, only more-severe degrees of steatosis are detected, and the prevalence of fatty liver is underestimated, with estimates of 70% of people with type 2 diabetes as having a fatty liver (76). Nonetheless, the prognostic power of merely the presence of a fatty liver is impressive of predicting the onset of type 2 diabetes. A large study of individuals with normal glucose tolerance at baseline showed a very low 8-year incidence of type 2 diabetes if fatty liver had been excluded at baseline, whereas if present, the hazard ratio for diabetes was 5.5 (range 3.6–8.5) (74). In support of this finding, a temporal progression from weight gain to raised liver enzyme levels and onward to hypertriglyceridemia and then glucose intolerance has been demonstrated (77).

Blood sugar level is measured by means of a glucose meter, with the result either in mg/dL (milligrams per deciliter in the US) or mmol/L (millimoles per litre in Canada and Eastern Europe) of blood. The average normal person has an average fasting glucose level of 4.5 mmol/L (81 mg/dL), with a lows of down to 2.5 and up to 5.4 mmol/L (65 to 98 mg/dL).
Could restricting your diet for a couple of days a week put type 2 diabetes in remission? That’s the controversial claim scientists of a small new study are making as they fan the fire around a diet fad known as intermittent fasting. But many health professionals, including those at the American Diabetes Association, argue that the approach can be dangerous for people with diabetes, whose bodies cannot control their blood sugar without careful diet, medication, and sometimes insulin management.
There is no prescribed diet plan for diabetes and no single “diabetes diet”. Eating plans are tailored to fit each individual's needs, schedules, and eating habits. Each diabetes diet plan must be balanced with the intake of insulin and other diabetes medications. In general, the principles of a healthy diabetes diet are the same for everyone. Consumption of various foods in a healthy diet includes whole grains, fruits, non-fat dairy products, beans, lean meats, vegetarian substitutes, poultry, or fish.
