TCM views the human body and its functioning in a holistic way. From this perspective, no single body part or symptom can be understood apart from its relation to the whole. Unlike Western medicine, which seeks to uncover a distinct entity or causative factor for a particular illness, TCM looks at patterns of disharmony, which include all presenting signs and symptoms as well as patients’ emotional and psychological responses. Humans are viewed both as a reflection of and as an integral part of nature, and health results from maintaining harmony and balance within the body and between the body and nature.3
The prevalence of prediabetes is also on the rise, as it’s estimated that almost 34 million U.S. adults were prediabetic in 2015. People with prediabetes have blood glucose levels that are above normal but below the defined threshold of diabetes. Without proper intervention, people with prediabetes are very likely to become type 2 diabetics within a decade.
Many people have heard about type 2 diabetes, but its common precursor, prediabetes, doesn’t get as much attention. Prediabetes is estimated by CDC to affect 86 million Americans (51% of whom are 65 years and older), and an estimated 90% of people with prediabetes don’t even know it. According to the CDC, 15-30% of these individuals will develop type 2 diabetes within five years. In other words, as many as 26 million people that currently have prediabetes could develop type 2 diabetes by 2020, effectively doubling the number of people with type 2 diabetes in the US.

Metformin: The DPP study found that metformin, the safest first-line therapy for type 2 diabetes, may help delay the onset of type 2 diabetes in people with prediabetes. Participants who took the low-cost generic drug had a 31% reduced risk of developing type 2 diabetes compared to the control group (those not on metformin or intensive lifestyle intervention). Again, 15-year follow up data showed that 17% of those on metformin continued to have a significant reduction in type 2 progression. At this time, metformin (or any other medication, for that matter) is not currently FDA approved for prediabetes, and it is sometimes prescribed “off-label” by a healthcare provider. Your healthcare provider can give you more information and determine whether metformin is a good option for you.

Chronic exposure of β-cells to triacylglycerol or fatty acids either in vitro or in vivo decreases β-cell capacity to respond to an acute increase in glucose levels (57,58). This concept is far from new (59,60), but the observations of what happens during reversal of diabetes provide a new perspective. β-Cells avidly import fatty acids through the CD36 transporter (24,61) and respond to increased fatty acid supply by storing the excess as triacylglycerol (62). The cellular process of insulin secretion in response to an increase in glucose supply depends on ATP generation by glucose oxidation. However, in the context of an oversupply of fatty acids, such chronic nutrient surfeit prevents further increases in ATP production. Increased fatty acid availability inhibits both pyruvate cycling, which is normally increased during an acute increase in glucose availability, and pyruvate dehydrogenase activity, the major rate-limiting enzyme of glucose oxidation (63). Fatty acids have been shown to inhibit β-cell proliferation in vitro by induction of the cell cycle inhibitors p16 and p18, and this effect is magnified by increased glucose concentration (64). This antiproliferative effect is specifically prevented by small interfering RNA knockdown of the inhibitors. In the Zucker diabetic fatty rat, a genetic model of spontaneous type 2 diabetes, the onset of hyperglycemia is preceded by a rapid increase in pancreatic fat (58). It is particularly noteworthy that the onset of diabetes in this genetic model is completely preventable by restriction of food intake (65), illustrating the interaction between genetic susceptibility and environmental factors.

Dr Beverley Shields, at the University of Exeter Medical School, who led the research, said: "This finding is really exciting. It suggests that a person with Type 1 diabetes will keep any working beta-cells they still have seven years after diagnosis. We are not sure why this is; it may well be that there is a small group of "resilient" beta-cells resistant to immune attack and these are left after all the "susceptible" beta-cells are destroyed. Understanding what is special about these "resilient" beta-cells may open new pathways to treatment for Type 1 diabetes."

One can't, in spite of the initial reported success of following a 600 kcal vegetarian diet for 8 weeks cured all 11 participants of their diabetes, resulting in an enormous very beneficial weight loss of 15 kg and reversal of pancreatic fat infiltration that many think is the underlying defect causing type 2 diabetes, see this 2011 paper Reversal of type 2 diabetes: normalisation of beta cell function in association with decreased pancreas and liver triacylglycerol only just 3 months afterwards diabetes had recurred in 5 out of the 11 see Diet reverses Type 2 Diabetes
This seems hard to do, but really it’s not if you know one secret: Replace snacking with something far more satisfying — fat. That’s right, the government is wrong to recommend a low fat diet. Fat is what makes you feel full until your next meal. Take away the fat, take away the full. Don’t go to an extreme, but do lean strongly toward a high-fat low-carb diet.
