“Today I’m cured of diabetes”


Before and after

Is diabetes type 2 an incurable disease? That’s what Bernard Bollen’s doctor told him, and that’s what conventional wisdom says.

Then Bernard found what has worked so well for so many people, and his life was transformed. Here’s his story:

The Email

Hello Andreas,
I am more than happy to offer a few paragraphs and a before and after picture. (Unfortunately I do not have before & after pics of my full body so a couple of facial shots is all that I can provide). I do hope that it may inspire others.

One year ago I weighed 125 kg (275 lbs). I took medications for diabetes, cholesterol and high blood pressure. I am 59 years old and have eaten a nutrition-sparse diet most of my life, high in sugars and refined carbohydrates. When I was first diagnosed with diabetes 6 years ago, my doctor told me that diabetes was a progressive disease that would require management, but that it was ultimately incurable. My feet were beginning to go numb, a sure sign of nerve damage in the extremities. A happy and healthy entry into my senior years seemed a distant possibility. I was resigned to what I saw as the inevitable, a limb amputation, blindness, a stroke or a heart attack.

Thus, one year ago I was not a happy camper. I decided to have bariatric surgery as I was led to believe that this could be a cure for diabetes. At this time I became increasingly aware of the relation between diet and health through numerous web searches. I was already aware of the Atkins diet (the 1st diet revolution), with its emphasis on a very low carbohydrate intake. I then became aware of the Paleo diet. Its underlying nutritional philosophy just made sense to me. I was sold; I cancelled my planned bariatric surgery and threw myself into the Paleo program. Over the next few months I certainly began to lose weight, but more, my whole relation to food and nutrition changed in ways that I could never predict.

The first thing I noticed was that eating three Paleo meals a day never left me hungry. In fact, I couldn’t eat three full Paleo meals a day, I was just too satiated. So I cut it down to two meals a day and was still never hungry. I always kept olives and macadamia nuts in the house in case I needed a top up. Now I eat one Paleo meal a day and am never hungry. I don’t know if this is a common experience but it certainly is mine. I have come to believe that one meal a day is OK when on a nutrition dense diet. Hunger is your body’s was of saying ‘I need some more nutrition’. If you are not hungry then you don’t need to eat. So why do people eat when they are not hungry? There are a number of reasons for this:

• The first reason is our dietary habits, we are brought up to practice and believe that we need three meals a day. So we eat three times a day irrespective of whether we are hungry or not. (It seems unlikely that our Paleo ancestors regularly ate three meals a day.)
• The second reason is that eating is a pleasurable experience, until satiation occurs, of course.
• The third reason relates to the idea that people are drawn to food when they are anxious, under stress or just plain bored, food seems to help.
• Fourth, it’s really hard to maintain a Paleo diet unless you regularly cook at home. For many, this will require a lifestyle change away from take away food and other forms of processed food consumption.

So the Paleo diet is more than sticking to a set of foods that we should or should not eat. My own personal experience is that the Paleo diet requires a confrontation with our whole relation to food, not just what we eat, but why we eat. For me this is an important point, I see it as a significant step in the identification of those who are at high risk of failing on the Paleo diet and return to their old eating habits.

One month ago I saw my doctor. Robert is a young, intelligent and open minded doctor who one year ago appeared to be sceptical of the benefits of the Paleo diet (so was I for that matter). Today he calls me his ‘poster boy patient’. Nearly all of the medications that I took a year ago have been dispatched to the bin. My life has been transformed in many ways.

After six months on the Paleo diet I had already lost 15 kg (33 lbs) and felt that I had made a health breakthrough. I was positive, I could do it. So I enrolled in a gym and regularly engaged in aerobic and resistance exercises. Now, 12 months later I have lost 30 kg (66 lbs) and I look and feel so much better. I now have some definition in my upper body muscles and have rediscovered my hips.

Today I am cured of diabetes. One other issue that occurred after 6 months into the program was the incredible rise in my libido. Really, I spend so much time now walking around like a bull in springtime. Maybe the universe will one day reward my efforts with a trim and terrific cavewomen to whom I can focus my attention.

Today, obesity and diabetes are the number one public health issues (yes, even more important than cigarettes, alcohol and drugs). Teenagers are getting type 2 diabetes. The evidence that sugars, refined carbohydrates and processed foods are responsible for this nutrition related epidemic is compelling. I am no longer on the Paleo program, I would prefer to call it a Paleo lifestyle since I see it as a lifelong commitment. I don’t believe that the Paleo diet is going to be the final word on health and nutrition. Critics of the Paleo diet deserve to be heard and respected (well many of them anyway). But the science behind the Paleo diet is sound and most importantly, it really works!!

Well this is my story of nutritional redemption; yours will almost certainly differ in some ways if you choose to go the path of Paleo.

I certainly do hope that it may inspire others.

Very Best,
Bernard Bollen


Congratulations on your impressive health improvements Bernard! And the best of luck in your search for a compatible cavewoman, that shouldn’t be too hard these days.

    Well done. I'm going to stop reading success stories, they make me despair. Low carb doesn't work for everyone. And even if my thyroid is dodgy my GP doesn't want to know and will not check it. Wish I had the money to go private.

    Well, high carb doesnt work for everybody either!

    And if its about the thyroids.. its not that much about diet.. except that everybody need to eat a healty diet!

    Im not sure if it can help you, but I give you a link anyhow.

    That's a dangerous and irresponsible headline. There's no cure for diabetes. You can manage it well without medication, you cannot "cure diabetes".

    NOTE: Referring to Type II DM only, Type I is, as of this time, incurable.

    I rather goes for Dr Fungs definition.. if you get a new lifestyle and you dont need any medication for your diabetes anymore.. then you are cured!

    The word "cure" is a little vague. If I have a condition that never returns, have I been "cured" -- even though the condition might possibly reassert itself under certain conditions? My severe allergies were also deemed incurable by the doctors. However, they went away entirely after embarking on a LCHF diet. The allergies would probably return if I went back on a high-carb diet. Am I cured? Does it really matter if we use this word or not? It is simply a matter of semantics. The fact remains: the disease, with its symptoms, is gone. That is what is of significance to me.

    Merriam-Webster defines cure as "a complete or permanent solution or remedy" and "recovery or relief from a disease."

    I consider my GERD to be cured. If I went back to eating very much fruit, grains and beans, I'm sure it would return. My allergies, aches and pains, wonky energy levels--same thing. The remedy has been to avoid things that make me ill. This is no different from being cured of an infection even if re-exposure to the bacteria or virus would make you sick again.

    "There's no cure for diabetes"


    As Dr. Fung explains it, the insulin dysfunction in type two diabetes is a side effect of the accumulation of fat in the liver and pancreas in response to elevated insulin from insulin resistance. The excess fat in the pancreas diminishes the functionality of pancreas beta cells. As Dr. Unger explains, the pancreas fails to generate a sufficiently strong local insulin pulse from the beta cells to shut down glucagon production in the pancreas alpha cells and then the liver creates sugar despite high blood sugar and high insulin. Then there is a self-reinforcing downward cycle until organs start failing. The typical treatment is to administer insulin, but elevated insulin is the root cause of the disease and so follwing the standard treatment of more calories from carbs than from fat and insulin injection is indeed a one-way street.

    This is why fasting can be so effective: successive episodes reduce and can eventually eliminate the fat accumulation in the pancreas and liver and, in many if not most cases, over time (on an LCHF diet) allows normal functionality to return slowly as beta cells replenish, thus ending type two diabetes. LCHF alone typically alleviates symptoms of type two diabetes (by reducing the insulin load needed to handle the reduced sugar and protein to a level within the range of remaining pancreas beta cell functionality) but LCHF alone might not be sufficient to eliminate liver and pancreas fat and achieve full restoration of beta cell functionality. LCHF would not be a cure in that case.

    This does not mean everyone will still have the regenerative capacity for beta cell functionality to restore after burning off pancreas fat, and other factors may complicate the process for many. The headline did not purport to claim that absolutely everyone can be cured of type two diabetes. Nonetheless, clinical experience shows that it is possible to cure type two diabetes.

    Hi all,
    I spent most of the weekend watching Dr. R. Bernstein's Diabetes University videos. He is managing diabetics (and type 1) with low carbohydrate diets. Of course type 1 diabetes is tricky and needs basal insulin as well as some fast acting insulin with meals. However, he keeps his patients on very low insulin and this reduces their long-term complications. Why do I not see his face among the LCHF experts? This guy is THE pioneer of the low carb diet. He is 80 years young.

    Well done. Great hearing your story. Very encouraging. It is not easy giving up sugar and carbs. I am early on in my efforts to stop eating sugar and carbs. I have systemic candida which i am taking medication for that kills it. It creates the Herxheimer effect, and terrible cravings for sugar. So reading your story, even though its different, is encouraging me to stay with the program! Well done!

    According to this study 90% of patients from bariatric surgery cure their type 2 diabetes.

    This article in Diabetologia journal explains how diabetes can also be reverted with a dietary intervention: "Reversal of type 2 diabetes: normalisation of beta cell function in association with decreased pancreas and liver triacylglycerol".

  13. Kaiser
    Very proud of you Bernie. You've done so well, and even though we both have the most diametrically opposed food paths, it's worked for you and made you well.

    Best of luck finding that cavewoman!

    There's at least one type I diabetic who is no longer diabetic after being treated with a paleo, ketogenic diet. His type I diabetes was autoimmune in nature and was caught early enough that his beta cells were able to recover.

    "Introduction: Type 1 diabetes mellitus (T1DM) patients are usually instructed to follow a low fat/high carbohydrate diet. A few studies in literature, however, reported metabolic benefits and sustainability of carbohydrate restricted diets.

    Case Report: Herein, we present a case of a 19-year-old male with newly diagnosed T1DM. The patient was first put on an insulin regime. Twenty days later, he shifted towards the paleolithic ketogenic diet and was able to discontinue insulin. Strict adherence to the diet resulted in normal glucose levels and a more than three-fold elevation of C-peptide level indicating restored insulin production. Currently, the patient is on the paleolithic ketogenic diet for 6.5 months. He is free of complaints, and no side effects emerged.

    Conclusion: We conclude that the paleolithic ketogenic diet was effective and safe in the management of this case of newly diagnosed T1DM. Marked increase in C peptide level within two months indicates that the paleolithic ketogenic diet may halt or reverse autoimmune processes destructing pancreatic beta cell function in T1DM. "

    This is a really inspiring story. It took courage and character to take responsibility for your health and I hope that it inspires other to do the same. Whatever you do, stay on the wagon, and continue to do what makes you well.

    Servicing all of the heifers hey!!! Hmm!! I guess worse things could happen to a man!! And you don't get much more Paleo then a GOOD HARD F(well you know what I mean).

    Murray, that is one of the best and most succinct explanations I've seen for intermittent fasting and LCHF.

    Personally, I think Dr. Fung should win an award (the Nobel prize for medicine?) because of his views and information. I have begun intermittent fasting mainly because of him, and it's helped me tremendously.

    Hello, everybody!! I was healed of Diabetes after praying to God to cleanse my soul. I was so convinced I was healed that I stopped entirely taking my meds, and haven't looked back ever since. Amen to that!!!!
    Thanks for sharing your story, Bill! Very exciting and encouraging to those who can appreciate the Lord and His healing ways….

    Cured? No. Controlled? Yes!
    A CURE sound tantalizing, doesn't it. Yet if this gentleman went back to eating a high carb diet, do you suppose he might "catch" diabetes once again?
    To answer my own question, no, because he isn't "cured" of diabetes, he IS in control of it, as many of us have done with a law carb lifestyle.
    I highly disagree with the Diet Doctor in this instance of putting this claim on his site. It's misleading and causes people to think they can use keto, or paleo, or lchf as a short term answer, and that's untrue and unkind as it can get people into a lot of trouble down the road.
    Keto Truth: this can give you non-diabetic numbers as long as you follow it but diabetes is like an angry bear hibernating in a cave - if you wake him, he will attack.
    I was diagnosed with a typerson 1 Diabetes a month ago. I am 19 years old The moment they gave me insulin I put myself on a lchf diet and reduced my insulin from 3x6units novo rapid and 10 units levemir at night to ONLY TWO UNITS LEVEMIR AT NIGHT! Now my sugar doesnt raise more than 6, everything is perfect. I am not a robot and I eat sweet from time to time but my sugar is still normal. Now I get 2 units every 2 days! Soon I will be off insulin and cured od diabetes 1. Even when I don't put insulin and eat carbs, sugar raises and falls by itself to normal after 2 hours which happens to every normal healthy person. Even if I eat sweet's it's okay and comes back to normal. Is it possible for my pancreas to starting to work again ??

    Dear friends in the world this my tetimoney Dr Oloh david Heall me from my Diabetes ,Then we cry out to God to work a miracle.

    That's what happened to me.

    I was around 42 when my lab values started to show signs of prediabetes. I worked a full-time job in an office setting, never getting up to move except to go to the cafeteria or snack bar. I also was the mother of five and the wife of a pastor.

    My husband was Type 2 diabetic, overweight and noncompliant with his medications. So I knew how serious diabetes was. When my doctor Oloh David mentioned it to me, the first thing I said was, "I'm not claiming that!"

    However, saying "I'm not claiming it" but not doing anything about it is the same as "claiming it"!

    My doctor Oloh David assured me that since this was caught early, He would allow me to work with a nutritionist to establish a diet plan and exercise schedule before putting me on medications.He would revisit this plan in six months.Glory be to God Dr Oloh David heal my daibetes and i am passing this to those that have daibetes that my Dr Oloh David is special in all this issues here is Dr Oloh email sharperodavid1@gmail.com you can contact him on email or call his number +2347014190267 your problem will be free he cure so many types of disease in the body testify yours and share it to the world to be safe ....
