Conventional medicine still has Type 2 diabetes pegged as a blood sugar problem. In reality, it's a disease rooted in insulin resistance1 and faulty leptin signaling, caused by chronically elevated insulin and leptin levels. In other words, it's a diet-derived condition.
Unfortunately, as noted by Dr. Abhinav Diwan, associate professor of medicine, cell biology and physiology at the Washington University School of Medicine in St. Louis,2 "In general, the concept of reversing or curing diabetes ... is not well-accepted in the medical field. It is not even a therapeutic goal when people start to treat diabetics."
This is why the medical community's approach to diabetes treatment, which typically involves the administration of insulin, is not getting anywhere. Treating Type 2 diabetes with insulin is actually one of the worst things you can do, and can even lead to the development of Type 1 (insulin-dependent) diabetes in some cases.
Conventionally trained doctors also continue to pass along seriously flawed nutritional information (such as recommending a high-carb diet and use of artificial sweeteners), which is yet another reason why Type 2 diabetes has ballooned to such epidemic proportions.
Most People Are on the Verge of Becoming Diabetic
An estimated 30.3 million Americans, nearly 1 in 10, have Type 2 diabetes.3 Another 84 million American adults — about 1 in 3 — are prediabetic. Prediabetes4 is defined as an elevation in blood glucose over 100 milligrams per deciliter (mg/dl) but lower than 125 mg/dl, at which point it formally becomes Type 2 diabetes.
However, any fasting blood sugar regularly over 90 mg/dl really suggests insulin resistance, and seminal work by the late Dr. Joseph Kraft suggests 80 percent — 8 in 10 — Americans are in fact insulin resistant,5 which means they're already well on their way toward developing diabetes.
That's the bad news. The good news is Type 2 diabetes is reversible, and the treatment doesn't cost you anything. In fact, it actually saves you loads of time and money. I'm talking about fasting. Both intermittent fasting and longer water-only fasting have been shown to reverse Type 2 diabetes.
Fasting — A Therapeutic Alternative to Insulin
A recent case series paper6,7 published in BMJ Case Reports by a friend, Dr. Jason Fung, details how fasting can be used as a therapeutic alternative for Type 2 diabetes. This exciting report actually made the front page of CNN online.8 As noted by the authors, their paper:
"… [D]emonstrates the effectiveness of therapeutic fasting to reverse insulin resistance, resulting in cessation of insulin therapy while maintaining control of blood sugars. In addition, these patients were able to lose significant amounts of body weight, reduce their waist circumference and also reduce their glycated hemoglobin levels."
A case series paper is not a controlled study; rather, it simply presents the case history of one or more patients and may propose a hypothesis for why a treatment did or did not work. In this case, three diabetic patients between the ages of 40 and 67 participated in a supervised fasting regimen to evaluate the effects on their insulin requirements. The patients had been diagnosed with Type 2 diabetes for 10, 20 and 25 years respectively, and were taking insulin daily.
Of the three patients, two did alternating-day 24-hour fasts, while one fasted for 24 hours three times a week over a period of several months. On fasting days, they were allowed to drink unlimited amounts of low-calorie fluids such as water, coffee, tea and bone broth, and to eat a low-calorie, low-carb dinner.
On nonfasting days, they were allowed both lunch and dinner, but all meals were low in sugar and refined carbohydrates throughout. The complete manual of the fasting regimen used is described in Fung's book, "The Complete Guide to Fasting."9
Two of the patients were able to discontinue all of their diabetes medications while the third was able to discontinue three of his four drugs. All three also lost between 10 and 18 percent of their body weight. As reported by the authors:
"In our study all three patients eliminated the need for insulin by initiating a therapeutic fasting regimen. All three patients succeeded within a month and one in as little as five days. Further, all patients improved in multiple other clinically significant health outcome measures, such as HbA1C, body mass index and waist circumference …
As such, patients with T2D can reverse their diseases without the worry of side effects and financial burden of many pharmaceuticals, as well as the unknown long-term risks and uncertainty of surgery, all by means of therapeutic fasting."
In another similar trial,10 Type 2 diabetics were placed on a severely restricted calorie diet where they ate just 600 calories a day for eight weeks. By the end of their fast, all were disease-free, and three months later, having returned to their regular diet, seven of the 11 participants remained free of diabetes.
