During this 8-week study, β-cell function was tested by a gold standard method that used a stepped glucose infusion with subsequent arginine bolus (21). In type 2 diabetes, the glucose-induced initial rapid peak of insulin secretion (the first phase insulin response) typically is absent. This was confirmed at baseline in the study, but the first phase response increased gradually over 8 weeks of a very-low-calorie diet to become indistinguishable from that of age- and weight-matched nondiabetic control subjects. The maximum insulin response, as elicited by arginine bolus during hyperglycemia, also normalized. Pancreas fat content decreased gradually during the study period to become the same as that in the control group, a time course matching that of the increase in both first phase and total insulin secretion (Fig. 3). Fat content in the islets was not directly measured, although it is known that islets take up fat avidly (24) and that islet fat content closely reflects total pancreatic fat content in animal models (25). Although a cause-and-effect relationship between raised intraorgan fat levels and metabolic effect has not yet been proven, the time course data following the dietary intervention study are highly suggestive of a causal link (21).
Treatment plans are designed around the pattern of insulin normally supplied by the pancreas throughout the day in someone without diabetes. In general, this involves providing a fairly steady "background" level of insulin to control blood sugar levels between meals and overnight, along with doses of rapid- or short-acting insulin to handle the fast rises in blood sugar that occur with meals.
According to the World Health Organization (WHO), global diabetes cases have increased from 108 million in 1980 to 422 million in 2014. Those numbers are expected to reach 642 million by 2040. According to data from the U.S. Centers for Disease Control and Prevention (CDC) reports, type 2 diabetes accounts for around 90 to 95 percent of cases in adults.
The above two rules are the only dietary rules you need to maintain ideal weight for the rest of your life, assuming you apply common sense and avoid extremes. The diet works by building in regular periods of insulin relief, keeping your body from becoming resistant to insulin. Following these two rules, you will maintain your weight and health by never entering the vicious cycle of increasing insulin resistance.
