My story is about the type 2 insulin-independent diabetes! If you are insulin-dependent (especially type 1), don't do Intermittent Fasting without permission and supervision of a doctor who has the expertise in both diabetes and fasting!
I was diagnosed with type 2 diabetes 9 years before starting Intermittent Fasting (IF). All these years, I was on metformin.
I stopped taking metformin and eating fast carbs (sugar, bread, potatos, rice, corn etc.) in the day I started IF. The experiment was not dangerous: if I had feel tired and sleepy (as it used to be when I forgot to take metformin for a couple of days), then I would immediately resume taking it. But that did not happen. My insulin was kept low in the natural way, and not through medication.
1.5 month after starting IF: a regular blood glucose test revealed 4.4 mmol/L (80 mg/dl). A blood sugar level below 6.0 mmol/L (106 mg/dl) is considered normal.
4 months after starting IF: I did a glycated hemoglobin test (Hb A1c) which shows the average level of blood sugar over the past 3 months. When glucose builds up in your blood, it binds to the hemoglobin in your red blood cells. The A1c test measures how much glucose is bound. Red blood cells live for about 3 months, so the test shows the average level of glucose in your blood for the past 3 months (source). Therefore, Hb A1c is more precise in discovering the real situation than the regular blood glucose test. The last one reflects the recent time only: sugar level can be low because of effective measures taken in the last couple of days, but that doesn't necesserely proves that diabetes doesn't exist. How to interpret the results of the Hb A1c test? For people without diabetes, the normal range for the hemoglobin A1c level is between 4% and 5.6%. Hemoglobin A1c levels between 5.7% and 6.4% mean you have a higher change of getting of diabetes. Levels of 6.5% or higher mean you have diabetes (source). My glycated hemoglobin test has revealed 4.5%:
What does it mean "IF reversed type 2 diabetes"?
Please read a fragment from the book The Time Machine Diet: Travel Back to Your Naturally Healthy Energetic Self I highly recommend (its author has won type 2 diabetes using IF as well):
The definition I used for "reverse" has been given by Ann Albright, PhD, RD, the director of Division of Diabetes Translation at the Centers for Disease Control and Prevention: "The term 'reversal' is used when people can go off medication but still must engage in a lifestyle program in order to stay off." The concept of "lifestyle change" sat just fine with me since it was obvious that my previous way of life was headed toward a dead end – pun intended.
You may find the concept somewhat debatable, as indeed many in the medical profession do. Such a definition, for instance, doesn’t outline the time needed to confirm the reversal; some insist on six months, some prefer one year, or other arbitrarily picked period. Its permanency is in your hands, however, as you are likely to remain in "at risk" group. If down the road for whatever reason you veer off course and fall "off the wagon" again, triggering the return of diabetes – that’s your own negligence which by no means diminishes the effectiveness of the method that brought you to remission. Nor can such improvement of your condition be a bad thing, so don’t let those doubts stop you. If the word "reversal" makes you uncomfortable, let’s call it "getting your test results in a healthy range." To sum it up, the view I subscribe to is: If your numbers indicate non-diabetic range and you can maintain this state without medications and unsustainable restrictions to your diet, the goal has been achieved, whether you call it reversal, remission or (stretching it a bit) cure.
You could ask: but why all those multipage brochures in medical centres, which give detailed advice how to deal with diabetes, don't contain even one mention of the magic combination "Intermittent Fasting + fast carbs avoidance" which simply dissolves the problem in full (rather than reduces its symptoms as diabetes drugs do)? Why smart, well educated and experienced doctors don't tell their patients, suffering from diabetes for decades, that it's possible to reverse diabetes quickly and easily? Type 2 diabetes is all about high level of insulin, so why all these doctors tell the patients to eat 5-6 times a day to keep insulin constantly high, instead of suggesting Intermittent Fasting which keeps insulin low most time of the day in the natural way? Come on! Who will bring billions of $ to those doctors (for periodic visits) and the pharmaceutical industry (producing endless tons of anti-diabetes pills)?
A fully reversible disease:
Most doctors, dietitians and diabetes specialists claim that type 2 diabetes is a chronic and progressive disease. The American Diabetes Association, for example, almost proudly proclaims this on its website. Once you get the diagnosis, it’s a life sentence. But, it’s actually a great big lie. Type 2 diabetes is almost always reversible and this is almost ridiculously easy to prove.
