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).
Chong points to previous research in Circulation that describes the underlying mechanisms of sleep apnea. In people with sleep apnea, activation of the sympathetic nervous system — including increased heart rate, increased blood pressure, and constriction of blood vessels — all led to a higher risk of heart attack and stroke, which can be compounded in people who have type 2 diabetes (and thus already have a higher risk of heart disease).
The first hint that type 2 diabetes is a fully reversible syndrome came from bariatric surgery. Almost a quarter century ago, Pories et al. (12) demonstrated that blood glucose levels normalized in obese people with type 2 diabetes undergoing bariatric surgery and that 10 years later, almost 90% remained free of diabetes. The phenomenon was more recently tested in a randomized prospective study comparing gastric banding with intensive medical therapy for type 2 diabetes (13). This least invasive type of surgery was most suitable for the randomized study, although it was associated with lower rates of diabetes reversal than other procedures. Mean fasting plasma glucose fell to normal levels in the surgically treated group but declined only modestly in the intensive medical treatment group despite oral agents and insulin (Fig. 1) (13). Remission of diabetes was related to the degree of weight loss rather than to group allocation and was achieved in 73% of the surgical group and 13% of the intensive medical treatment group because surgery was more effective in achieving weight loss as previously described (14). Type 2 diabetes can be reversed by applying a surgical procedure that diminishes fat mass.
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.
In addition to walking and stretching exercises, try interval training cardio, like burst training, or weight training three to five days a week for 20–40 minutes. Burst training can help you burn up to three times more body fat than traditional cardio and can naturally increase insulin sensitivity. You can do this on a spin bike with intervals, or you can try burst training at home.
Cinnamonium cassia and its relative C. burmanii are the types of cinnamon that have the best effect on diabetes symptoms. There have been numerous studies on cinnamon and, overall, they have shown cinnamon can slow stomach emptying and lower postprandial glucose levels. It also reduces glucose levels in Type 2 Diabetes Mellitus patients who have had poor diabetic control. It may also be helpful in lowering insulin levels, blood pressure, and A1C, and reduce AGE formation. This is a safe herb for diabetics. A good dose is 1 to 2 g a day or 200 mg or more of a concentrated extract.
Implementing integrative and functional medical nutrition therapy, I helped the patient understand that she could reverse the trajectory she was on by making lifestyle changes—and that’s what she did. We engaged in shared decision making in our ongoing nutrition consultations. Over the course of one year, her physiology and health status changed for the better. Her A1c dropped from 7.2% to 5.6%, and she no longer required medications. She continues to adhere to her new lifestyle program and is confident she’ll remain free of a diabetes diagnosis.

Diabetes has grown to “epidemic” proportions, and the latest statistics revealed by the U.S. Centers for Disease Control and Prevention state that 30.3 million Americans have diabetes, including the 7.2 million people who weren’t even aware of it. Diabetes is affecting people of all ages, including 132,000 children and adolescents younger than 18 years old. (2)
Benefits of control and reduced hospital admission have been reported. However, patients on oral medication who do not self-adjust their drug dosage will miss many of the benefits of self-testing, and so it is questionable in this group. This is particularly so for patients taking monotherapy with metformin who are not at risk of hypoglycaemia. Regular 6 monthly laboratory testing of HbA1c (glycated haemoglobin) provides some assurance of long-term effective control and allows the adjustment of the patient's routine medication dosages in such cases. High frequency of self-testing in type 2 diabetes has not been shown to be associated with improved control. The argument is made, though, that type 2 patients with poor long term control despite home blood glucose monitoring, either have not had this integrated into their overall management, or are long overdue for tighter control by a switch from oral medication to injected insulin.
Even if you don’t have any underlying glucose issues, testing your blood sugar occasionally will help you pin point which carbohydrates you tolerate well and which you don’t. It can help you have a better understanding of your body’s reaction to foods and take control of your health. It is also an accurate alternative to the pregnancy test for gestational diabetes, so talk to your doctor if you’d prefer to test yourself, though you may have to explain your reasons!
The more intense the exercise, the better. According to the British diabetes association diabetes.co.uk, high-intensity interval training (HIIT) may be better for weight loss and glucose control than continuous aerobic activity like jogging. HIIT involves alternating between short bursts of increased intensity exercise and rest — for instance, running and then walking on and off throughout the workout.
Since type 2 diabetes is merely excessive glucose in the body, burning it off will reverse the disease. While it may sound severe, fasting has been practiced for at least 2000 years. It is the oldest dietary therapy known. Literally millions of people throughout human history have fasted without problems. If you are taking prescription medications, you should seek the advice of a physician. But the bottom line comes to this.
“Whether it be the patient saying for the fifth time ‘I will start watching my diet and start exercising,’ or a physician saying ‘the A1c is close to goal and I don’t really want to add yet another medication and copay, we will wait and see what happens in another 3 months,’ the end result is lack of intensification and A1c goal attainment,” Pantalone said.
FEED YOUR GUT BUGS, not just yourself. There are trillions of bugs that live in your gut – their health is critical in determining your health. Many studiesshow links between the state of your gut bugs (your microbiota) and type 2 diabetes. Start improving the health of your gut immediately by eating five servings of different coloured vegetables each day. The non digestible fibre in vegetables is the preferred food for your gut bacteria and when your gut bugs are happy, you will be happy. The wider the variety of colours, the more phytonutrients you will be getting.
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.
“I have many ways to help patients manage diabetes, but it’s very hard to reverse,” says Dr. Rita Louard, director of the Clinical Diabetes Program at Montefiore Health System in Bronx, New York. Still, some diabetes experts will use the word “reverse” when talking about this topic, Louard says, acknowledging the controversy that exists when discussing diabetes reversal.
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.
