There was a clinical trial conducted at Department of Biochemistry, Postgraduate Institute of Basic Medical Sciences Madras, India that studied 22 patients with type 2 diabetes. It reported that supplementing the body with 400 mg of Gymnema Sylvestre extract daily resulted in remarkable reductions in blood glucose levels, hemoglobin A1c and glycosylated plasma protein levels. What’s even more remarkable is that by the end of this 18 month study, participants were able to reduce the dosage of their prescription diabetes medication. Five were even completely off medication and attaining stable blood sugar levels with Gymnema Sylvestre supplementation alone.
For over a decade, Cummings and others have tried to reframe the very concept of bariatric surgery (they prefer “metabolic surgery”). Their work has shown these procedures just don’t change how much food the stomach can fit; they trigger a cascade of metabolic and bodily changes, many of which help people with type 2 diabetes naturally get their blood sugar under control. Some changes even start happening before a patient loses weight, such as higher levels of peptide production in the gut that seem to restore a patient’s sensitivity to insulin.
Want to learn more about diabetes drugs? Read the “Diabetes Medicines” series from certified diabetes educator Amy Campbell, covering metformin, sulfonylureas, meglitinides, thiazolidinediones, DPP-4 inhibitors, SGLT2 inhibitors, alpha-glucosidase inhibitors, bile acid sequestrants and dopamine receptor agonists, and non-insulin injectable diabetes medications.

I tried the above hydration / dehydration cycle with my father in June 2014. At that time he was 80 year old. He suffered from Sepsis, Multiple organ failure, Chronic Kidney Disease Stage 5, High Blood Pressure, Severe Constipation, Prostate issues, Epilepsy and Gangrene. The doctors had opined that it is impossible that he can survive even if taken to the best of hospitals in the world.
Some of the above drugs are available in compound form, and there are many patients taking three to four of them to control their blood sugar. But again, "the most common duo is metformin and a sulfonylurea,” says Arti Bhan, MD, division head of endocrinology at Henry Ford Health System in Detroit. “Metformin makes the body utilize insulin more effectively, and the sulfonylurea works on the pancreas to make more insulin in response to food consumption. Another common combination is metformin and insulin.”
A wide scatter of absolute levels of pancreas triacylglycerol has been reported, with a tendency for higher levels in people with diabetes (57). This large population study showed overlap between diabetic and weight-matched control groups. These findings were also observed in a more recent smaller study that used a more precise method (21). Why would one person have normal β-cell function with a pancreas fat level of, for example, 8%, whereas another has type 2 diabetes with a pancreas fat level of 5%? There must be varying degrees of liposusceptibility of the metabolic organs, and this has been demonstrated in relation to ethnic differences (72). If the fat is simply not available to the body, then the susceptibility of the pancreas will not be tested, whereas if the individual acquires excess fat stores, then β-cell failure may or may not develop depending on degree of liposusceptibility. In any group of people with type 2 diabetes, simple inspection reveals that diabetes develops in some with a body mass index (BMI) in the normal or overweight range, whereas others have a very high BMI. The pathophysiologic changes in insulin secretion and insulin sensitivity are not different in obese and normal weight people (73), and the upswing in population rates of type 2 diabetes relates to a right shift in the whole BMI distribution. Hence, the person with a BMI of 24 and type 2 diabetes would in a previous era have had a BMI of 21 and no diabetes. It is clear that individual susceptibility factors determine the onset of the condition, and both genetic and epigenetic factors may contribute. Given that diabetes cannot occur without loss of acute insulin response to food, it can be postulated that this failure of acute insulin secretion could relate to both accumulation of fat and susceptibility to the adverse effect of excess fat in the pancreas.

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.
