This 2013 paper on page 5 reported that after the 8 weeks on that 600 kcal diet 10 out of the 11 participants, so not all, of the Counterpoint study, as the study is now known, regained normal glucose metabolism, 3 months after resuming a normal diet 4 out of the 10 still had a normal glucose metabolism, 3 had an impaired glucose tolerance, 3 had better controlled diabetes, no more recent figures published in spite of the first publication had been published in Octobre 2011, which doesn't bode well for the long term outcome I'd say, I'd have expected them would to have reported the longer term results by now were they positive.
It was the same endorsement the first Diabetes Surgery Summit, also organized by Cummings in 2007, had made, but the landscape had changed since then. In addition to more accumulated research, this time, their stance was backed by over 50 international professional organizations, including the American Diabetes Association. And while other medical societies and organizations had long backed surgery as an option for diabetes, the DSS-II guidelines are the first meant to guide clinical practice.
Panax ginseng (Korean ginseng), which has a long history of use as a hypoglycemic agent. At least five constituents of this herb have been shown to exert hypoglycemic effects. In one study, treatment with ginseng lowered blood glucose levels and improved mood and psychological performance as compared with placebo. Recommended dosage is 100–200 mg/day.14
What’s critical is not necessarily the cutoff itself, but where someone falls within the ranges listed above. The level of risk of developing type 2 diabetes is closely related to A1c or FPG at diagnosis. Those in the higher ranges (A1c closer to 6.4%, FPG closer to 125 mg/dl) are much more likely to progress to type 2 diabetes, whereas those at lower ranges (A1c closer to 5.7%, FPG closer to 100 mg/dl) are relatively more likely to revert back to normal glucose levels or stay within the prediabetes range. Age of diagnosis and the level of insulin production still occurring at diagnosis also impact the chances of reverting to normoglycemia (normal blood sugar levels).
What is prediabetes? Prediabetes is a condition where blood sugar levels are higher than normal, but not high enough to be diagnosed as type 2 diabetes. This occurs when the body has problems in processing glucose properly, and sugar starts to build up in the bloodstream instead of fueling cells in muscles and tissues. Insulin is the hormone that tells cells to take up glucose, and in prediabetes, people typically initially develop insulin resistance (where the body’s cells can’t respond to insulin as well), and over time (if no actions are taken to reverse the situation) the ability to produce sufficient insulin is reduced. People with prediabetes also commonly have high blood pressure as well as abnormal blood lipids (e.g. cholesterol). These often occur prior to the rise of blood glucose levels.

A major feature of the disease is a condition known as insulin resistance.  Insulin is a hormone that moves glucose (sugar), from the bloodstream into the body’s cells where it is used for energy.  For a variety of reasons that are not fully understood, the body’s tissues don’t respond adequately to insulin and glucose then becomes elevated in the bloodstream.

Use any combination of the tricks below to accelerate your weight loss and return to good health. If you use all five wisely, you can get to your ideal weight in 6–12 months or less — even if that means losing 100 pounds or more. Yes, think about your weight 10, 20, 30 years ago. Another friend of mine started on this journey last year weighing 270 pounds. He’s in his mid-thirties and about to reach his college wrestling weight class of 197 pounds and just ran his fastest 2 miles ever. He got to this point by following the two rules above and just 3 of the 5 tricks below.
