How to Reverse Type 2 Diabetes – The Quick Start Guide


It’s possible to simply reverse type 2 diabetes. There are only two things you need to do.

By reading this brief post you’ll know what they are, and how to get started. Or skip ahead to the two steps right away >

Quick start

Twenty years ago, when you bought a brand sparkly new VCR machine, you would also get a thick instruction manual. Read this thoroughly before you start, the manufacturer would implore. There would be detailed setup procedures and troubleshooting guides.


Most of us ignored the manual, just plugged it in and tried to figure out the rest. That’s why we all had the blinking 12:00 on. Today, most new electronics now come with a quick start guide which has the most basic 4 or 5 steps to get your machine working and then anything else you needed, you could reference the detailed instruction manual. Instruction manuals are just so much more useful this way.

Well, I don’t know much about VCRs, but I do know about type 2 diabetes. I can write an entire book about obesity (oh, wait, I did that already), or fasting (oh, wait, coming up) or type 2 diabetes (next up for 2018). But many of you will not want to go through the entire instruction manual. So this is the quick start guide for reversing your type 2 diabetes.

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. This is great news for the more than 50% of American adults who have been diagnosed with pre-diabetes or diabetes. Recognizing this truth is the crucial first step in reversing your diabetes or pre-diabetes. Actually, it something that most people already instinctively recognized to be true.

peterSuppose your friend is diagnosed as diabetic, then works hard to lose 50 pounds. He takes himself off all his medications and his blood sugars are now normal. What would you say to him? Probably something like “Great job. You’re really taking care of yourself. Keep it up!”

What you wouldn’t say is something like “You’re such a dirty, filthy liar. My doctor says this is a chronic and progressive disease so you must be lying to me.” It seems perfectly obvious that diabetes reversed because your friend lost all that weight. And that’s the point. The disease is reversible.

We’ve known this all along. But only diet and lifestyle changes will reverse it. NOT medications. The most important thing, of course, is to lose weight. But the diabetes medications don’t do this. Quite the contrary. Insulin, for example is notorious for causing weight gain. Patients intuitively sense that they are heading down the wrong path.

They would often say to me, “Doctor. You’ve always said that weight loss is the key to reversing diabetes. Yet you prescribed me a drug that made me gain 25 pounds. How is that good?” I never had a good answer, because none existed. It was not good. The key was weight loss, whereupon the diabetes often goes away or at least gets significantly better. So, logically, insulin does not help reverse the disease, but actually worsens it.

Other medications such as metformin or the DPP4 drug class are weight neutral. While this won’t make things worse, they won’t make things better either. Since weight loss is the key to reversing type 2 diabetes, medications won’t make things better. Medications make blood sugars better, but not the diabetes. We can pretend the disease is better, but that doesn’t make it true.

That’s the reason most doctors think type 2 diabetes a chronic and progressive disease. We’ve been using the wrong treatment. We’ve been prescribing drugs for a dietary disease. No wonder it doesn’t work.

So, how can you reverse your diabetes?

The sugar bowl

The essential feature of type 2 diabetes and pre-diabetes is that our bodies are completely filled with sugar. It’s not just too much sugar in the blood. That’s only part of the problem. There’s too much sugar in our entire body.

Imagine our bodies to be a sugar bowl. A bowl of sugar. When we are young, our sugar bowl is empty. Over decades, we eat too much of the wrong things – sugary cereals, desserts and white bread. The sugar bowl gradually fills up with sugar until completely full. The next time you eat, sugar comes into the body, but the bowl is full, so it spills out into the blood.

pouring_sugarInsulin is a normal hormone produced when we eat and its job is to allow glucose into the cells. When it is no longer able to do it, glucose piles up outside the cell in the blood, and it is called insulin resistance.

But why does this happen? The cells are already over-filled with glucose (see previous post – A New Paradigm, and Insulin Resistance is Good?). Like trying to blow air into an over-inflated balloon, it simply takes more force. The cell resists the glucose because it’s completely full. Insulin resistance is an overflow phenomenon.

It’s like packing your clothes into a suitcase. At first, the clothes go without any trouble. After a certain point, though, it is just impossible to jam in those last 2 T-shirts. You can’t close the suitcase. The luggage is now ‘resistant’ to the clothes. It’s waaayyy harder to put those last 2 T-shirts than the first 2. It’s the same overflow phenomenon. The cell is filled to bursting with glucose, so trying to force more in is difficult and requires much higher doses of insulin.

Full-suitcaseWhen the insulin levels are unable to keep up with the increasing resistance, blood sugars rise and your doctor diagnoses you with type 2 diabetes and starts you on a pill, such as metformin. But metformin does not get rid of the sugar. Instead, it simply takes the sugar from the blood and rams it back into the liver. The liver doesn’t want it either, so it ships it out to all the other organs – the kidneys, the nerves, the eyes, the heart. Much of this extra sugar will also just get turned into fat.

The problem, of course, has not been solved – the sugar bowl is still overflowing. You’ve only moved sugar from the blood (where you could see it) into the body (where you couldn’t see it). So, the very next time you eat, the exact same thing happens. Sugar comes in, spills out into the blood and you take metformin to cram the sugar back into the body. This works for a while, but eventually, the body fills up with sugar, too. Now, that same dose of metformin cannot force any more sugar into the body.

So you go to your doctor. What does he do? Instead of getting rid of the toxic sugar load, he doubles the dose of the medication. If the luggage doesn’t close, the solution is to empty it out, not use more force to . The higher dose of medication helps, for a time. Blood sugars go down as you force your body to gag down even more sugar. But eventually, this dose fails as well. So then your doctor gives you a second medication, then a third one and then eventually insulin injections.

Over a period of years, you went from pre-diabetes, to diabetes, to taking one medication, then two then three and then finally large doses of insulin. Here’s the thing. If you are taking more and more medications to keep your blood sugars at the same level, your diabetes is getting worse! Even if your blood sugars get better, your diabetes is getting worse. This is unfortunately what happens to virtually every patient. The body is already overflowing with sugar.

The medications only hide the blood sugar by cramming it into the engorged body. The diabetes looks better, since you can only see the blood sugars. Doctors can congratulate themselves on a illusion of a job well done, even as the patient gets continually sicker. Patients require ever increasing doses of medications and yet still suffer with heart attacks, congestive heart failure, strokes, kidney failure, amputations and blindness. “Oh well” the doctor tells himself, “It’s a chronic, progressive disease”.


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.

You needed to throw out the garbage, not hide it away. If we understand that too much sugar in the blood is toxic, why can’t we understand that too much sugar in the body is toxic too?

The end game

GangrenousFootWhat happens over time – 10, 20 years?

Every single part of the body just starts to rot. This is precisely why type 2 diabetes, unlike virtually any other disease, affects every part of our body. Every organ suffers the long term effects of the excessive sugar load. Your eyes rot – and you go blind. Your kidneys rot – and you need dialysis. You heart rots – and you get heart attacks and heart failure. Your brain rots – and you get Alzheimers disease. Your liver rots – and you get fatty liver disease. Your legs rot – and you get diabetic foot ulcers. Your nerves rot – and you get diabetic neuropathy. No part of your body is spared.

Medications and insulin do nothing to slow down the progression of this organ damage, because they do not eliminate the toxic sugar load from our body. We’ve known this inconvenient fact since 2008. No less than 7 multinational, multi-centre, randomized controlled trials of tight blood glucose control with medications (ACCORD, ADVANCE, VADT, ORIGIN, TECOS, ELIXA, SAVOR) failed to demonstrate reductions in heart disease, the major killer of diabetic patients. We pretended that using medications to lower blood sugar makes people healthier. But it’s only been a lie. You can’t use drugs to cure a dietary disease.

How to reverse diabetes

Once we understand type 2 diabetes, then the solution becomes pretty bloody obvious. If we have too much sugar in the body, then get rid of it. Don’t simply hide it away so we can’t see it. There are really only two ways to get rid of the excessive sugar in the body.

  1. Don’t put sugar in
  2. Burn it off

That’s it. That’s all we need to do. The best part? It’s all natural and completely free. No drugs. No surgery. No cost.

Step 1 – don’t put sugar in

The first step is to eliminate all sugar and refined starches from your diet. Sugar has no nutritional value and can therefore be eliminated. Starches are simply long chains of sugars. Highly refined starches such as flour or white rice are quickly broken down by digestion into glucose. This is quickly absorbed into the blood and raises blood sugar. For example, eating white bread increases blood sugars very quickly.

Doesn’t it seem self-evident that we should avoid foods that raise blood sugars because they will eventually be absorbed into the body? The optimum strategy is to eat little or no refined carbohydrates.

Too much dietary protein is also converted into glucose by the body. Therefore, you should avoid eating too much protein as this, too will only add sugar to the body. Protein shakes, protein bars, and protein powders should all be avoided. Instead focus on eating lots of vegetables and natural healthy fats.

Dietary fat, long shunned for its purported effect of causing heart disease, is back. Natural fats, such as found in avocado, nuts and olive oil are well known to have healthy effects on both heart disease and diabetes. The Mediterranean diet, high in natural fats, is well accepted to be a healthy diet.


Dietary cholesterol has also been shown to have no harmful effect on the human body. Eggs and butter are back. Most importantly, stick to eating whole, natural, unprocessed foods.

Step 2 – burn it off

Fasting is the simplest and fastest method to force your body to burn sugar for energy. Glucose in the blood is the most easily accessible source of energy for the body. Fasting is merely the flip side of eating – if you are not eating you are fasting. When you eat, your body stores food energy. When you fast, your body burns food energy. If you simply lengthen out your periods of fasting, you can burn off the stored sugar.

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.

If you don’t eat, will your blood sugars come down? Of course.

If you don’t eat, will you lose weight? Of course.

So, what’s the problem? None that I can see.

We can reverse type 2 diabetes and pre-diabetes today, right now, immediately. All without cost, without drugs, without surgery, with an all natural, time-tested healing method. We only need to lead our bodies down the healing pathway and have the courage to apply our hard-won knowledge.

    Dr Fung-
    Respectfully, it is not 'of course'. I have not touched a processed carb, gram of sugar, processed oil or refined carb since January. I fast 16/8 and keep my carbs to <25 net, my protein is between 70-80g per my doctor. I take 120 units of lantus & am down to 30 units of novalog, along with metformin. My sugars are still in the 200's and I fight to get them below that. My Dr has said it will take time & I am progressing, but it is simply not as easy as 2 steps & poof! it all works like magic. I have come to understand that small improvements are milestones for me, but I find it misleading to give the impression that it will work immediately for everyone. Recently, I have added high intensity muscle failure exercises & that is helping bring my sugars down far more than cutting carbs & protein.

    Electromagnetic radiation, wi-fi, smart meters, I suspect they raise blood sugars. Mine got worse
    when the smart meters came to my high density neighborhood. I've heard it called Diabetes 3.

    I don't understand your comments here about Metformin, which don't jibe with some previous from you. In addition, a cursory search on Google Scholar, for 2016, reveals:

    Metformin is not just an antihyperglycaemic drug but also has protective effects on the vascular endothelium http://onlinelibrary.wiley.com/doi/10.1111/apha.12644/abstract

    "The vascular protective actions of metformin are thought to be secondary to the antihyperglycaemic effects of metformin that are mediated via activation of AMP kinase and subsequent inhibition of hepatic gluconeogenesis, fatty acid oxidation as well as an insulin sensitizing action in striated muscle and adipose tissue. As reflected by a number of clinical studies, patients treated with metformin also have improvement in endothelial function as measured by the use of plethysmography and measurement of flow-mediated vasodilatation. These data as well as data from animal studies are supportive that metformin has a direct protective action on the vascular endothelium."

    There are different types of diabetes, that is; subtypes of 1 and 2. Recently more was discovered about the insulin producing cells. Plus, like any cells, they are affected by toxins, epigenetics, antibiotics and lack of nutrients.

    It would be great to hear you explain why all but ONE of The Biggest Losers gained back all the weight and more, and when tested for metabolism at that point, were found to be burning up to 800 calories less than a person their body size and age. Any calories over and they gained massively. Please explain how your diet would be different, and what you would have your dieters do to battle metabolism.

    I would also like to know HOW long have some of your dieters kept the weight off, the fat off, and their measured blood sugar down?

    Unless the Swedish doctor answers, I won't go further in my consideration to become a member here.

    My dad has type 2 diabetes and his legs were amputated six years ago. He is one of the slimmest people I know and has been all his life. My aunt from my mother side is 400 pounds 5 feet tall and does not have diabetes. She has been obese most of her life.

    To say that diabetes and being fat goes hand is hand has not proven to be correct, at least to me. Lifestyle choices? Absolutely but I think gene predisposition have a lot to do with it as well.

    I agree with the writer that diabetes can be reversed with the proper nutrition and exercise and unfortunately in our culture (hispanic) grains is a huge part of our diet along with fried foods.

    Both my mom and dad have diabetes. My mother is starting to develop neuropathy symptoms however she won't change her diet. I am worried about her but she gets defensive and lies about her diet even though I know the truth.
    In light of all of this I have decided to take care of myself and have changed my diet dramatically. I feel 100% better and while weight loss may become an added bonus it's not my end all goal; my health is.

    Speak to your doctor - you possibly have type 1 diabetes or LADA (can be checked with blood test for auto-antibodies), rather than type 2 diabetes. This approach only works for type 2 diabetes without end stage pancreas failure

    Metformin and other diabetic drugs slows down the entire body metabolism which slows down glucose processing so the crippled pancreas islet of Langerhan cells can keep up. The metabolism slowdown makes physical exercise more difficult for those taking Metformin. One way to slowdown the metabolism naturally is to cut the caloric level in the diet (glycemic load) another way is to eat only foods that are digest at a slower rate (glycemic index). The damage to pancreatic islet aka islet of langerhan cells is similar to that in brain tissue for Alzheimer's patients - the research I have read suggest the damage to the pancreas is due to animal fats/choloestrol plus hi levels of glucose in the blood stream. While some fish based Omega 3 fatty acids might have protective value - most animal based fats appear to correlate to damage not just the heart but other important organs in the body... so switching to a near vegan diet and fasting while not a quick fix will likely stabilize further internal organ damage for most early stage Type 2 diabetics who is still able to produce some insulin. This will not help a late stage Type 2 diabetic or a Type 1 diabetic who cannot produce insulin, their organ damage is so severe that they will still need insulin--- but a diet lifestyle change may help them manage their glucose levels better and keep the insulin injections down to only what is necessary. Fasting can be dangerous for some - in the UK there is entire movement based on periodic sustained fasting - caloric reduction diet that is done every month or every two weeks. I'm not sure why it is not cross the pond to the Americas....

    Other than high sugar and fat diet , the pancreas can be damaged by hypoxia (temporary loss of oxygen in the blood), medication ( pentamidine, SSRI antidepressants), Rat poison Vacor, polychlorinate hydrocarbons (PCB), H1N1 influenza, Coxsackie virus, entroviruses, and cancer (pancreatic cancer)...

    I was diagnosed with type 2 diabetes two months ago. I was told three years ago that I am pre-diabetic and ignored the doctor's advise to get retested. Since becoming a diabetic, I have stopped eating refined sugars and carbs but still eat cheese, proteins, cook with olive oil, eat nuts, some fruits in the morning and tons of veggies. I exercise at least 30 minutes a day. I was not obese when I was diagnosed but slightly overweight. Since then I have dropped 12 pounds cutting the sugars and carbs. The doctor retested my blood count and was happy with the improvement. He is giving me another month to lost more weight and decrease my blood sugar count. If I get it closer to normal limits he said I don't have to go on any meds. I am really trying and I have to say the first 45 days was very hard. I am now getting used to not eating "junk", and feel great. I have never felt better. Every time I see a donut I think of losing my sight or losing a toe. Guess what, donuts don't look so good to me anymore. I choose to live!!!

I have lost 28lb!! I am still on the diet and do a brisk 30 minute walk every day and longer at the weekends. I've got my first fasting blood test booked on 9th January , this alone will prevent me from breaking my diet just because it's Christmas!!

    I'm with you buddy !I thought I had diabeties ten years before my doctor put me on metformin and glimiperide. I tried to diet but I'd get all cold and clammy and dizzy, so I stopped taking those meds and decided to do things the old fashioned way. I've lost one hundred pounds doing all the programs and videos and switching it up. Now I use " Simply fit Board ", and eat fruit, vegetables, beans, and lowfat popcorn for snacks. I eat all the time but not after four p.m. I'll go back to my doctor when I've reached my goal weight. Goodbye, heel spur, hello bikini !

    Hello all, Registered Dietitian over here with my input.

    I've reluctantly followed Dr Fung's work for over a year now because of the inherrent danger that his insane theories and unoriginal ideas pose to the diabetes populations, weight loss populations as well as the medical community. First and foremost let's understand his background is in nephrology (kidney disease) so listening to a nephrologist talk about weight loss and nutrition is like getting your plumber to install a new muffler or exhaust system in your car based on the fact that plumbing and the exhaust system have pipes so it's 'basically the same thing.' This is the approach Dr Fung has taken in these outlandish claims. He seems to pride himself on being a medical doctor but offers no evidence to support his claims that type 2 diabetes can be reversed of which is a absolute requirement in the medical community otherwise you might as well be a witch doctor and say 'trust me.'

    Secondly, let's understand his qualifications in discussing nutrition, which is absolutely none. As a Dietitian, I have 4 years of undergraduate studies with 1 year of an applied internship, have to write a standardized entrance exam to confirm my competency and requirements from my regulated college to update my skills each year. This is to recognize that nutrition is a complex interaction of social, emotional, mental, physical and financial health. This took 5 years minimum for me and all other dietitians to study before we were considered entry level dietitians. What type of training do you have Dr Fung? did you enthusiastically take 1 semester of nutrition and think you've figured it all out because that's exactly what it seems like. You have no respect for the limitations of your own scope of practice or knowledge for that matter (based on your poor understanding of diabetes, it's medications and your incredibly stupid and misleading metaphors) along or respect for other medical practitioners.

    Thirdly, this man is actively manipulating the public by making promises he can't keep in order to sell his book he has no intention on helping anyone (which is a crock of BS, how do you write an entire book on fasting? Step 1: don't eat... where the hell is step 2?).

    Fourthly, the advice given in this article alone is DANGEROUS. You're telling people about the dangers of insulin and medication and telling them it's the cause of their weight gain and that you can reverse diabetes by losing weight? Well guess what? All you've done is communicate to diabetics that NEED their medications to not take them anymore to cure themselves resulting in uncontrolled blood sugars causing the EXACT damage that you describe in the section that you entitle 'The End game' and you can't make this connection. You can't make the connection that telling people not to take their medications will cause uncontrolled blood sugars which in time to cause nerve damage which can cause irreversible damage to all the organ systems that you discuss and most notably the kidneys! YOU'RE A NEPHROLOGIST? HOW CAN YOU NOT MAKE THIS CONNECTION?????

    For someone claiming to 'cure' diabetes you sure don't seem to understand the disease and have proudly manipulated the public by using the word 'cured' as opposed to the accurate word of 'controlled.' using the word 'cured' implies that someone no longer needs to engage in the lifestyle and dietary factors that brought them to their success, something Dr Fung would know if he had any education in behavioural change theories, models and human behaviour.

    Finally, Dr Jason Fung has a well documented history of fat shaming and harassment. This year's obesity conference has 2 overweight keynote speakers and Dr Fung tweeted out to question the validity and qualifications of the experts because they were overweight themselves. He has deleted the tweet like a coward but prior to that responding to people call him out on this type of unacceptable behaviour like a coward acting like he didn't know exactly what he was doing and likely deleted the tweet after being advised by a PR consultant to do so, not out of genuine apology. If you don't believe me go ahead and re-read this poorly written article and notice that he thinks the only thing that causes diabetes is weight. Obviously he's never encountered a thin person with poorly controlled blood sugars, likely because he thinks they're cured.

    Dr Jason Fung is a hack and a fraud. He offers nothing to the advancement of medicine and is an unethical practitioner that should have his credentials and education reviewed. I have personally worked with the people that have come out of his weight loss program that have put the weight back on and people that have read his book. My colleagues have all had clients that have been terribly misled from Dr Fung's insane and poorly thought out theories supported by cherry picked data, if at all.

    "What do you call a person that barely passes medical school? Doctor" Please think about this quote if you've read anything by Dr Jason Fung.

    Dear Ben Sit,

    Your attack on Dr Jason Fung is unfounded. To me, his advise on fasting is really fine tuning towards an overall regimen of high fat (healthy fats, not seed oils), low carb (fibre bound carbs are best) & moderate protein adherence. I have been closely following the LCHF diet since Oct 2011 and have permanently kept off 55 lbs of excess weight. Most all of my biomarkers, such as inflamation, blood pressure, brain fog, blood sugar etc are improved. Mainstream medical advise is very much out of touch with the latest research, and I suggest that you would do well to learn more about the subject of LCHF.

  28. Ben Sit
    Dear Terry,

    My attack on Dr Fung is both valid and warranted. I'm glad you were able to lose weight as sustain it however the attack on Dr Fung is based on his unethical, immoral and unprofessional behaviours. Clearly a lot of my critique went above your head so I would invite you to reread it and interpret it from the perspective of potential harm to the population, lack of professional training in nutrition, appealing to manipulative and misleading promises and claims. Furthermore you must understand that this is an opinion of Dr Fung that is shared widely throughout the medical community, not just me.

    I'd like to inform you that my knowledge of the LCHF diet is well versed, as it is with every diet in existence as that is a requirement of being a qualified dietitian. I'm not disagreeing that it works but I'm arguing it's sustainability and effectiveness for the general population. It clearly has worked for you and you deserve congratulations for it however Dr Fung presenting it as an 'innovative' new way to combat obesity is far from the truth. It is neither innovative nor is it new. It is simply a variation of diets that have existed in the past, such as atkins, the Keto diet etc. All of which have been well studied and are adaptions to starvation. That's right, this isn't medically assisted weight loss this is medically assisted starvation . What a LCHF diet is attempting to do is stimulate ketosis in order to utilize fat as the primary energy source which is not appropriate for every population (I'd explain all the contraindications and issues but I simply don't have the time to write that much). The issue is that when you go off of it you gain all the weight back, which is why I end up seeing a lot of the people that come off his program 'cured.' I'm glad this diet worked for you but can you honestly tell me that you're 100% happy on it? that you don't miss certain foods from your childhood? that you don't feel socially isolated when you have to have a special meal at social gatherings? I'd go on and on but I hope you get the idea.

    You provide the insight that mainstream medical advice is out of touch from the latest research and I assure you that there is good cause for this and it has to do with the ethics of quality of research and the amount of research done. You can always find research to back up your claim (eg the fallacy of the heavily misguided anti vaccine movement) but it takes experienced practitioners to interpret the overall body of literature in order to make sound and responsible judgement. Having 1 paper that goes against the main body of literature warrants more research in that area before responsible medical practitioners can safely make judgements on the efficacy of treatment and this is my issue with Dr Fung's approach, it lacks responsibility, ethics and evidence.

    You condescendingly invited me to learn more about LCHF; do the countless papers, research, meta analysis, textbooks, books, conferences and lectures that I've attended on the topic matter count? That's what I thought.

    Heh, your whole argument consists of an appeal to authority that's cause a worldwide epidemic of metabolic disease.

    And I can say I'm perfectly happy eating whole, unprocessed, food. Now, that processed stuff tastes like crap.

    I think you're main problem with LCHF is you'd be out of a job.

    Hi Tim,

    Would you mind rewriting and proof reading your reply to my comment? I was barely able to understand it with the grammatical and typographic errors.

    I'm glad you're perfectly happy eating whole, unprocessed foods. This is fantastic for you. However there are many complicated factors that prevent people from being able to do this. A good example would be basic economics combined with food science. Whole, unprocessed foods cost more than processed foods and waste faster than processed foods. Now imagine yourself living below the poverty line with 2 jobs. Food choices become much more difficult due to financial restrictions and time restrictions for preparation. Additionally you may not even have the necessary cooking tools and equipment to cook a healthy food and all that's available to you is a microwave and a sink. This forces you to go to food banks where the majority of the food donated is processed to maintain food safety and to prevent spoilage for liability reasons and food safety reasons. So recognize that while you have the privilege, means and ability to be able to afford whole and unprocessed foods that the majority of the world doesn't, which is a major factor contributing to the obesity epidemic. Was this ever considered in your solution to worldwide obesity? Furthermore have you considered the increasing rise of eating disorders and disordered eating associated with compliance to restrictive diets? Would you call that healthy?

    As for your opinion on why you assume that I'm against LCHF diets (of which I never actually indicated, you just assumed) that's not the case at all. I've put clients on LCHF diets because it was the right treatment option for them and it's worked successfully for them. However the LCHF diet isn't for everyone and that's the point I'm trying to make; that there are multiple ways to achieve a goal. No one diet or lifestyle modification is above any other. Furthermore the LCHF diet has potential risks associated, increased colorectal cancer risk due to low fibre intake associated with carbohydrate restricted diets is just a small example but did anyone ever tell you that or did they just rave about how much weight they've lost? You think I'd be out of a job? Well it's people like Dr Fung, Dr Bernstein, Dr Oz, Instagram nutritionists, and general misinformation out there that actually give me job security.

    Another major issue is that health is poorly understood by the general population. There are many factors that contribute to health. Some examples are; social health, economic health, sexual health, physical health, spiritual health, emotional health, mental health etc etc etc. What Dr Fung doesn't seem to comprehend is that full commitment to one's physical health through diet comes at the cost of other avenues of health, the most common being social, emotional and mental health. You may be at a 'healthy' weight, (which is subjectively defined) but if it causes an eating disorder in the process would you say that person is healthy?

    Quite wordy...baffle 'em with bullsh!t. You obviously know nothing about LCHF or you would know it's high in fiber. Leafy vegetable are a main portion, and full of insoluble fiber.

    More appeal to the authority which has caused a worldwide epidemic of metabolic disease.

    If you people knew what you were doing, this wouldn't be happening...


    Or this...

    Yup, it's wordy because I'm an academic and that's just the tip of the ice berg in it's complexity but apparently the work of thousands of obesity, nutrition, public health etc researchers is bullshit just because you can't seem to grasp the abridged version of what I've written.

    Ok let's take your example of meeting fibre requirements in a LCHF diet. Now using Kale as an example (due to it's popularity as a health food), it's nutritional profile states that it has 1g of fibre per 1 cup serving size accompanied by 6g of carbohydrate. In order to meet the daily requirement of 25g of fibre per day for women and 38g of fibre per day for men, you'd have to eat 25-38 cups of kale depending on your biological sex for optimal health which would provide approximately 150-228g of Carbohydrate per day. Now eating 25-38 cups of kale per day is ridiculous so let's be more modest and take the average fibre intake of Americans of 15g/day, giving us a total carbohydrate intake of 90g per day. Why is this important? because ketosis (the alternative energy pathway that's used in states of starvation) is initiated in daily carbohydrate intakes below 20-100g of carbohydrate depending on which research paper you read on ketosis/ physiological adaptations to LCHF diets. It is also the primary mechanism to utilize fat as an energy source which is what the LCHF aims to do. So in your ludicrous example of meeting your fibre requirements through 15-38 cups of green leafy vegetables per day, the very physiological mechanism by which the LCHF diet aims to use fat as the primary fuel source is most likely deactivated, good example. Also, how much does 15-38 cups of kale cost? Is it affordable to anyone below the poverty line? will you be donating kale to a food drive? I'm not even going to go into the difference between soluble and insoluble fibre or the different vitamins and minerals found in green leafy vegetables vs red or yellow vegetables or the many cases of heavy metal toxicity from excessive Kale consumption.

    "More appeal to the authority which has caused a worldwide epidemic of metabolic disease"

    I'm sorry but do you fully understand what that actually means in this scenario? Capitalism and the industrial revolution are big factors to blame for these health issues. They're not the only factors, but major ones. Do you see me actually writing in support of those factors? No. I haven't given my opinion on anything other than the fact that Dr Fung is clearly abusing his title as an MD and making outlandish and irresponsible claims to sell books. Again you fail to acknowledge or comprehend the aspect of finance or economics when offering your own opinion into this multifaceted issue. How do you propose modern agriculture be rapidly overhauled to support the world's population to address the obesity epidemic? What you're saying also has political elements that would appear that you're against democratic capitalistic societies because if we were to ignore finance as you have to provide healthy food for everyone in your opinions and comments then it could be seen as support for a socialistic or communistic government but I'm sure that's not what you mean is it?

    Given that you haven't produced a coherent or well thought out rebuttal to any of my arguments, given provided a poorly thought out example of how to meet fibre requirements through a LCHF, 1 link that only establishes what we already know to be true which is America's obesity problem is rising and the other article which is a purposefully misleading as obesity is better measured with out statistics such as per capita vs by numerical count alone (Population of America is currently 316.5 million and the population of China which is currently at 1.357 billion, which is 4 times that of America. Did you really think the the numerical count means more than a per capita or percentage of population as a statistic? or that the two populations were good as points of comparison?) this will be my last response as I'm clearly wasting my time and could have written a dissertation.

    I didn't say LCHF doesn't work I just said it's unrealistic and unsustainable for the majority of the population and that there are other ways to address the same issue in other people. At the end of the day, you do what you think is best but just know that it may not work for everyone. Claiming that it works for everyone is my primary issue. Best of luck to you

    Heh, one cup of avocado has 40 grams of fiber all by itself...

    You can blame shift all you like, the fact is if you people knew what you were doing, the below wouldn't be happening. Your recommendations produce sickness and death. An epidemic that can be proven to have begun since the 'wisdom' of the pharmaceutical and food processor funded 'nutritionist' took over.


    Or this...

    Edit...Heh, one cup of avocado has 10 grams of fiber all by itself...anyway, a lack of fiber has never been proven to be a problem. Correlation doesn't prove causation, which is what almost all nutrition studies do. The Eskimos ate almost pure fat...don't think they were troubled by a lack of fiber.

    Sorry, I had to come back for more and I'm glad I did because your responses are getting hilarious now. Aside from: your obvious lack of any formal training, over inflated sense of ego and false sense of education to try to appropriately debate someone that is clearly more versed in this topic than you can possibly understand, your biases have become completely clear now. You're a post-truth, irrational and uneducated advocate of the LCHF diet because. Perhaps it's gotten you to lose a bit of weight and that's all you need as evidence and proof that it works for the rest of the world's population, but I speculate and digress. I only wonder which fad diet you're going to jump to next (I hear the military diet is getting quite popular now a days). Tell me; since you believe I, along with all the other educated and well trained Dietitians and healthcare providers, give "recommendations produce sickness and death" (Tim, 2017) how would you tackle obesity? Please provide your insight into how we can solve this growing problem for the world because all I see from your responses is half-baked, poor comprehension and over simplified thoughts that are unoriginal, privileged and completely void of empathy. You're not offering any suggestions are you? You're just arguing for the sake of arguing because clearly I've hurt your feelings and your ego and your sense of pride and ego outweighs your need for education. I suggest you get one outside of Netflix Documentaries, articles written by unqualified individuals and books written by people that have no interest in actually helping to solve the issue (just make some quick cash out of it) and go to an accredited university program to even start to make a small contribution to this greater conversation.

    'a lack of fiber has never been proven to be a problem' oh so we're just going to ignore all the literature that supports fibre in the reduction of colorectal risk? You're absolutely right, correlation doesn't prove causation but I'm sure the nuances of the difficulty and complexities in nutrition research will be lost on you. Now let's take your off handedly offensive example into consideration. The Inuit and First nations peoples (Eskimo is a racist term by the way) that have a diet high in fat and protein because that's all the nutrition that was available to them given the climate that they live in. Over many generations the inuit and first nations people have been able to evolve to deal with that diet. Furthermore, has it been proven that they have lower rates of colorectal cancer? When time period are you basing your statement? Do you know what medical imaging equipment is used in those extreme conditions? What was the average age of the study (that you're not actually referring to, you're just making an assumption) participants? Was longer life expectancy from modern medicine taken into account? No. You didn't incorporate ANY of these important variables in your outlandishly simplified statement. Furthermore, if you actually want to make a statement on the limitations of Nutritional research I suggest you actually look at nutritional research yourself instead of rehashing someone else's biased opinion and interpretation of data and research. I also have to point out the irony of you providing surprisingly good insight into how correlation not meaning causation but at the same time point out a correlational association of health and modern medicine and the rise of modern agricultural practices combined with the rapid rise in capitalism. You say it's proven? Then give me some evidence that's not the exact same 2 non-scientific articles you reference. That was probably the most laughable thing in your entire attempt to engage me in conversation/ debate. I also love your statement of how your assumption of my clinical practice is causing harm when I'm the one cleaning up Dr Fung's mess. The amount of clients I've had to deal with because their Basal Metabolic Rate, Healthcare markers (eg BP, Blood sugar, Cholesterol, Triglycerides, Liver Enzymes etc) have been thrown out of whack because they thought that Dr Fung or a LCHF could 'save' them and reverse their diabetes is frightening.

    Finally you should probably take a look at this article about your false god; Dr Fung:


    Sorry I can't continue this conversation but I've got to go ahead and run my empire now. Again, I wish you all the best and hope that you take your passion for nutrition and give it the structured unbiased learning environment that it deserves. There are many fantastic university and college programs and if you're lucky you might end up in one of my classes!

    I was diagnosed of diabtes 3 years ago. I used food to manage it but didn't see much of a results. If you find yourself in such a situation, please reduce your regular intake of food to say 50%. Support it with an hour a day exercise and the results will surprise you. My type 2 diabetes is completely reversed. I feel very healthy and strong

    Been LCHF and 20/4 fasting for 3 months. I have lost 70 lbs. Scoring mid 80's blood glucose fast and have a 5.3 A1c. I have a ways to go but my doctor halved my doses of Metformin and my blood pressure medicine and I suspect I will be off metformin completely at my next office visit. I've done a couple of 24 hour fasts and 1 48 hour fast. The worst thing is the mind games your brain plays. Funny thing... My older daughters come home from college and complain there is no "food" even though the refrigerator is full. This has really changed my lifestyle. I gave up beer, but not the bourbon or tequila although I do these very moderately. I've come to like salads with this mustard/vinaigrette dressing the wife makes up. Chicken, beef, salmon and eggs are the mainstays along with green vegetables and cauliflower. I like tuna fish with almond mayonnaise too! I figure I have 8 more months to get to where I want to be physically. I will never touch sugar again and will continue the IF for the rest of my life. I am not missing anything.

    How high is your sugar when u are diagnosed?
  42. One
    Well i am not a Dr....you doctors can fight all you want. My experience is that i was on medication (metformin) which made me feel sick most of the time. Then put on insulin injection and my blood sugars kept going high and sometimes very low. I started with fasting (for religious reasons) before i read all these researches, and my blood sugar got lower than usual, then i decided on the diet after fasting and i have been feeling great!! i keep checking my blood sugar and so far so good. I have not been taking insulin for 2 months now and my blood sugar level has been good.

    Gotta love the info from said 'Dietician'. What are your thoughts on 7 year olds with Type 2? This was unheard of in the past few decades, and now figures are through the roof. Perhaps something is wrong when the sugar industry can dictate that a high carb low fat diet is correct, and then the pharma industry mop up with Metformin and Insulin in what they describe as a 'degenerative disease' by owning government bodies meant to protect people. Diabetes is controllable certainly, and cureable in a lesser %. In the UK people are now being removed from the diabetic register after X amount of positive HB1AC tests. Diet & exercise is all it takes. Treat the cause, not the symptoms!!
  46. SJ
    Btw, 'Dietician' tell me what part of any insight you have heard here is incorrect. The following is being promoted as a cure/control for type 2:

    -Weight Loss
    -Sensible lower carb intake

    Your argument back
    -Fat shaming

    Maybe the world needs more fat shaming, because being told that a bottle of metformin is the solution doesn't work. But, as you state...you have an 'empire' to run and we should attend more of your classes....except that you are a mouthpiece of the generations of rinse and repeat doctors that came before you with no critical analytic skills. Also, we ARE/WERE the ones with diabetes. We managed it/cured it and didn't accept what our doctors told us. So yeah, keep telling us just how stupid we are!

    Ben Sit,
    Your statements to Tim, "Would you mind rewriting and proof reading your reply to my comment? I was barely able to understand it with the grammatical and typographic errors.", and, "Yup, it's wordy because I'm an academic", show that you are a legend in your own mind! Anyone with an ounce of intelligence can understand a comment whether it has grammatical and typographic errors or not. Your statements show what a pathetic person you are. Wow, you are an academic, how impressive, that means you must be right and everyone else is wrong! I am also an academic, but would never use that in a statement to back up my argument, or insult someone by saying their comment contains grammatical and typographic errors. People don't need an English degree to have a legitimate opinion.

    Ben Sit,
    (Removed text here /Moderator)... You have no "true" understanding of nutrition and how it applies to metabolic syndrome. You consider yourself an "academic" yet are unwilling to learn and apply new research. You choose to reference antiquated data to support your "education." Let's look at the real world. I was diagnosed with diabetes two years ago with an A1C of 11.5 After following Dr. Fung's advice, I now have an A1C of 5.7..... Diabetes reversed! With your advice people would continue to remain sick and get worse. Thanks to "true pioneers" like Dr. Fung people are reversing their disease and improving their lives for the fist time in history! Thank you Dr. Fung!
    All great leaders and teachers are criticized for their brilliance.

    How fooliah i was to listen to Dr Berg and go on a Keto diet. That's when my glucose went from 5.1 to 7 and all broke loose.
    LCHF is a lie and will destroy your cholesterol and sugars and it will ruin your life.
    Instead go on a mediteranean or Rina diet.
