LOW CARB KETO DIET – Debunking 7 Misleading Statements


Let’s face it the ketogenic diet is arguably the most popular dietary trend in our world today, especially for those living with diabetes. It is likely that you’ve been tempted to follow a ketogenic diet to lose weight, drop your A1c and flatline your blood glucose. Even though it may seem tempting to enter the metabolic state of ketosis it’s important to understand the caveats of ketosis, so that you fully understand your risks for developing long-term complications. What exactly is ketosis, and why is ketosis a popular recommendation for those living with diabetes? A ketogenic diet is a very low carbohydrate diet by design containing a maximum of 30 grams of dietary carbohydrate per day. At the base of the ketogenic food pyramid are eggs, dairy, meat, oil, and fish, which make up the bulk of calories eaten. Starchy vegetables contain too much carbohydrate energy and are avoided while non starchy vegetables or green vegetables are included along with nuts, seeds, and a very limited amount of fruit, mainly berries. Now, the ketogenic diet explicitly prohibits the consumption of grain products, even whole grains as well as pasta, refined sugar, milk, corn, legumes, including lentils beans and peas, as well as rice. When you eat a ketogenic diet your muscles and liver switch from oxidizing glucose as their primary fuel to fatty acids as their primary fuel, and in order to withstand a very low carbohydrate intake your liver manufacturers ketone bodies as an emergency backup fuel for your brain when in the state of ketosis. If you’re living with diabetes this may sound like a great idea, because your pancreas is provided with an opportunity to reduce insulin production insulin due to low carbohydrate intake. Now, millions of people around the world who eat a ketogenic diet achieve a flatline blood glucose profile and greatly reduce or eliminate their need for oral medication and insulin. If You’ve experienced this yourself you may be thinking “Great! I solved the problem eating! A ketogenic diet is keeping my blood glucose in control and therefore my diabetes health is going up!” In addition, the state of ketosis induces a number of short-term benefits, including rapid weight loss, reduced fasting glucose, reduced post-meal blood glucose, reduced A1c, reduced total cholesterol, reduced LDL cholesterol, and flatlined blood glucose. The problem is that eating a ketogenic diet significantly increases your risk for chronic disease and premature death in the long term. After researching the advice from the top ketosis gurus we made a list of the seven biggest and most dangerous misconceptions about ketogenic diets in this video. We’ll go into detail about the truth underlying ketosis, and refute many common statements backed by misleading science, incorrect biochemistry, and a fundamental lack of understanding of human biology. Ketosis misconception number one: Insulin is your fat storage hormone. Now, you may have heard people in the ketogenic community refer to insulin as your fat storage hormone, and that by adopting a very low carbohydrate diet you prevent your blood glucose from spiking after a meal. Now, hold on a second, open any biology textbook and you’ll find that the primary function of insulin is to help glucose exit your blood and enter tissues. But that insulin also helps fatty acids and amino acids out of your blood and into tissues. It is absolutely critical to understand that the primary function of insulin is to help transport glucose out of your blood and into tissues and a secondary effect of insulin is to help transport fatty acids and amino acids out of your blood and into tissues Simply because insulin has the ability to transport fat into tissues does not mean that it’s factually correct to label insulin as your fat storage hormone. This is a gross exaggeration of the actual role of insulin and it is meant to scare people into believing that any amount of insulin in circulation will make you fat. Insulin triggers macro nutrient uptake in this order: Priority number one: Insulin transports glucose into the tissues to either be burned for energy or to be stored as glycogen for later use. Priority number two: Insulin transports fatty acids into tissues to be immediately burned for energy or to be stored as triglycerides for later use. Priority number three: Insulin transports amino acids into tissues to be synthesized into new protein to be burned for energy or to be converted into other compounds. Understanding this insulin priority hierarchy is very important, because it reinforces the concept that insulin’s primary role is to handle all things related to glucose metabolism BEFORE it begins directing fatty acids and amino acids into tissues. Insulin is the most powerful anabolic hormone in your body, meaning that it promotes more growth and more fuel storage than any other hormone in your body. Ketogenic dieters exaggerate this fact, condemning insulin entirely claiming that even small amounts of insulin will make you fat. Fact: Insulin is the most anabolic hormone in your body, responsible for more fuel storage and cell growth than any other hormone in your body. Fact: Insulin promotes more growth than testosterone. Fact: Insulin promotes more growth than estrogen. Fact: Insulin promotes more growth than growth hormone. Fact: Insulin promotes more growth than IGF-1. The truth is that all mammals secrete insulin because insulin is absolutely required for life. Your dog secretes insulin, your pet hamster secretes insulin, your neighbor’s cat secretes insulin, monkeys secrete insulin, raccoons secrete insulin, your non-diabetic co-worker secretes insulin. In fact insulin is so important that if your body stops manufacturing it, you’ll die. Without insulin your dog would die, your pet hamster would die, your neighbor’s cat would die, your non-diabetic co-worker would die. In truth a physiologically normal amount of insulin is absolutely required to stay alive. But secreting or injecting excess insulin is what substantially increases your risk for coronary artery disease, atherosclerosis and cardiovascular disease as a whole. Ketosis misconception number two: eating carbohydrates spikes your blood glucose. Proponents of the ketogenic diet often argue that eating any food containing carbohydrate energy will spike your blood glucose and that the only way to avoid dangerous glucose spikes is to avoid carbohydrate-rich foods. Technically speaking, when you eat carbohydrate rich food your blood glucose will rise. Furthermore, reducing your carbohydrate intake will keep your blood glucose more stable. For these reasons ketogenic dieters maintain a total carbohydrate intake less than 30 grams per day, representing less than 10% of total calories on average. What those in ketosis don’t understand is that the amount of glucose in your blood is not only determined by the amount of carbohydrate that you eat, but instead a reflection of both your dietary carbohydrate and your dietary fat intake. We have written extensively about the detrimental role that excess dietary fat plays in the development of insulin resistance, leading to high blood glucose, increased insulin requirements, high cholesterol, beta cell death, and increased risk for many chronic diseases. It’s important to understand that only paying attention to how much carbohydrate you eat will mislead you into thinking that this single macronutrient controls your entire blood glucose profile, when in reality your blood glucose is determined primarily by how much fat you eat and, secondarily, by the amount of carbohydrate that you eat. To understand how your blood glucose responds to different macro nutrient profiles, let’s explore how a ketogenic diet a standard American diet and a low-fat plant-based whole food diet affect your blood glucose. When operating in a high fat ecosystem on a ketogenic diet the primary reason why your blood glucose remains flat is because of the near absence of carbohydrate rich foods. In this way eating a high-fat diet is very effective at flat-lining your blood glucose because carbohydrates are kept below 30 grams per day. As long as you avoid carbohydrate-rich foods your blood glucose is likely to stay very stable. But the minute you choose to eat carbohydrate-rich foods such as a banana, a potato, a bowl a quinoa, your blood glucose is likely to increase significantly due to a hidden state of fatty acid-induced insulin resistance. The standard American diet is a perfect example of a diet that is high in both carbohydrate and high in fat which increases your risk for high blood glucose, insulin resistance and diabetes. Because both fat and carbohydrate are president in large quantities controlling your blood glucose becomes increasingly difficult over time. Because a low-fat plant-based whole food diet is low in dietary fat your carbohydrate tolerance or your ability to eat carbohydrate-rich food increases substantially resulting in maximum insulin sensitivity and the opportunity to completely reverse insulin resistance altogether. When operating in a low-fat eco system on a plant-based diet it is quite easy to maintain flatline blood glucose as long as your total fat intake is maintained below approximately 30 grams per day and your carbohydrate intake comes from whole foods like fruits, vegetables, legumes and whole grains, and not from products containing refined sugars. Ketosis misconception number 3: Diabetes is carbohydrate toxicity and insulin resistance is a state of carbohydrate intolerance. Those in the ketogenic community often labeling diabetes as a problem of carbohydrate toxicity, suggesting that dietary carbohydrate is the primary cause of the disease process. In addition ketogenic dieters believe that insulin resistance is caused by insulin itself, triggered by an excess consumption of dietary carbohydrate. I cannot tell you how many people tell me: Cyrus, insulin resistance is not caused by fat. It’s caused by insulin. This my friend could not be farther from the truth. In order to make these statements factually correct it’s necessary to go back to basic biochemistry principles and understand that the vast majority of people who develop insulin resistance do so by eating a diet containing large amounts of dietary fat as we discussed earlier. The research world has known this for more than 85 years. This was first established in the 1930s by the pioneering work of doctors Rabinowitch and Hemsworth, then further proven by Dr. Kempner in the 1950s and by Dr. Anderson in the 1970s. Despite this the cause of insulin resistance and carbohydrate intolerance remains one of the most debated subjects in the world of diabetes even today. Think of insulin resistance as a series of metabolic dominoes. The dominoes are arranged in this order: number one – you eat a diet containing dietary fat greater than about 15 percent of total calories; number two: you go and eat a banana, a potato or a bowl of rice, and check your blood glucose two hours later to find that your blood glucose meter reads a high number like two hundred and forty six. You point your finger and say Hey, bad banana, bad potato! I guess these foods are bad for me because clearly when I eat them they increase my blood glucose. The reason this happened is not because bananas and potatoes and rice are bad foods but because insulin receptors in your muscle and in your liver have become dysfunctional due to too much dietary fat. That’s right under normal circumstances the glucose from these carbohydrate-rich foods are accompanied by insulin, and insulin job is to say Knock-knock, I have some glucose. Would you like to take it up? Normally cells in your liver and muscle would say Sure bring it in! but when you’ve eaten your way into insulin resistance, insulin receptors say You got to be kidding me! Do you see how much energy I already have inside? I gotta burn this stuff first! And then and only then will I allow glucose in. For now you stay in the blood. So when glucose becomes trapped in your blood due to these dysfunctional insulin receptors you have a choice: either you avoid carbohydrates like the plague and continue to remain in ketosis, or you drop your fat intake and gain the ability to eat carbohydrate-rich foods. So if diabetes is not a problem of carbohydrate toxicity but a problem of fat toxicity then the correct statement is this: Insulin resistance is a state of carbohydrate intolerance first created by the consumption of excess dietary fat Ketosis misconception number four: Carbohydrate is not an essential nutrient. The ketogenic world is quick to point out that there is no such thing as an essential carbohydrate in contrast to required nutrients like essential fatty acids and essential amino acids. While this statement is technically true, labelling glucose as a non-essential carbohydrate implies that there is no use for glucose in the human body. Once again, we have to return to basic human physiology in order to understand the truth. Your liver, your muscle and other peripheral tissues are capable of oxidising glucose amino acids and fatty acids for energy. Your brain, however, cannot oxidise either amino acids or fatty acids for energy your brain can only run off of glucose for energy and does not possess the biological machinery to store glucose. As a result your brain must oxidise glucose on demand importing glucose from your blood 24 hours a day. Since glucose is your brain’s principal on-demand fuel, carbohydrate-rich foods are your brains primary fuel source. When you consume a low carbohydrate diet you force your liver to synthesize an emergency backup fuel known as ketone bodies to prevent against brain starvation, and you enter the state of ketosis in which ketone bodies become your brains primary fuel. Ketogenic diets were originally invented for people with epilepsy and are effective at reducing seizure incidents. However ample evidence shows the ketogenic diets come with a laundry list of unwanted side-effects that simply cannot be overlooked, including, but not limited to, diarrhea, nausea, constipation, vomiting, acid reflux, hair loss, kidney stones, muscle cramps, muscle weakness, hypoglycemia, low platelet count, impaired cognition, inability to concentrate, impaired mood, disordered mineral metabolism, stunted growth in children, increased risk for bone fractures, osteopenia, osteoporosis, increased bruising, acute pancreatitis, hyperlipidemia, high cholesterol, insulin resistance, elevated cortisol, heart arrhythmia, myocardial infarction or heart attacks menstrual irregularities, amenorrhea or loss of periods in women, and an increased risk for all-cause mortality or premature death from any cause Yes, that’s right, people who eat low carbohydrate diets die sooner and suffer for more disease in the long term If that’s not enough to dissuade you from eating a low carbohydrate diet, I’m not sure what is. Therefore, labelling carbohydrates as non-essential is not only factually inaccurate, it results in a wide variety of chronic health conditions that may ultimately shorten your lifespan decrease your quality of life and accelerate your risk for chronic disease. Ketosis misconception number five: low fasting insulin means high insulin sensitivity. People in the ketogenic community often measure their fasting insulin levels as an indicator of their insulin sensitivity. A fasting insulin test measures the amount of insulin your pancreas must secrete in order to control your blood glucose. The lower the number the less work your pancreas is performing. This is a good thing. Ketogenic dieters often report very low fasting insulin levels and then draw the conclusion that their insulin sensitivity has increased. This could not be farther from the truth. The only way to actually measure your insulin sensitivity is to utilize a glucose challenge in which you either drink a solution containing glucose dissolved in water, or you eat a food containing carbohydrate energy in the clinic. Your doctor may order a glucose tolerance test to measure your insulin sensitivity. The way that you measure insulin sensitivity using an oral glucose tolerance test is straightforward: Step 1: you drink a solution containing 75 to 100 grams of glucose dissolved in water. Step 2: a medical professional samples your blood at 0, 60, 120 and 180 minutes. Step 3: your blood samples are analyzed for glucose and insulin. Step 4: your performance is measured against a standard to determine your insulin sensitivity. The higher your glucose and insulin area under the curve the worse you perform on the test and the higher your level of insulin resistance The lower your glucose and insulin areas under the curves the lower your level of insulin resistance. The reason why this test is so valuable for measuring insulin sensitivity is because it measures the ability of your muscle and liver to uptake glucose from your blood when challenged by a food or drink containing glucose. Simply measuring your fasting insulin or fasting blood glucose independent of a glucose challenge is insufficient information to conclude anything about your level of insulin sensitivity. However, many ketogenic dieters and medical professionals fail to understand this concept entirely. If you never challenged your glucose metabolism with carbohydrate rich foods, or with a glucose solution, it is simply impossible to measure insulin resistance. Despite this, those in ketosis often claim that their insulin sensitivity has increased, even though they avoid eating carbohydrate-rich foods at all costs. Ketosis misconception number 6: low carbohydrate diets are not high-protein diets. Let’s go into detail to understand the caveats of this statement. The first question to ask is this: What proportion of total calories constitutes a high-protein diet according to the scientific evidence? Now, according to the evidence, diets containing more than 10 to 15% of total calories of protein increase your risk for cardiovascular and diabetes mortality especially if the majority of your protein originates from animal foods. Now, many studies have shown that protein intakes in excess of 15% of total calories increase your risk for heart disease, for high cholesterol, for atherosclerosis, for diabetes and various forms of cancer. As a result any diet containing in excess of 10 to 15% calories from protein is considered a high protein. It turns out that it is practically impossible for a ketogenic diet to be low in protein Why? It’s actually quite simple – because cheese, eggs, meat, butter, poultry, fish, nuts, seeds, vegetable oil, coconuts and avocados make up the bulk of calories in a ketogenic diet. With the exception of vegetable or coconut oil, which is 100% fat every food that I just listed is not only high in fat, but also higher in protein. Ketosis misconception number 7 Evidence-based research shows that low carbohydrate diets are effective. Low carbohydrate diet advocates are masters of documenting the efficacy of their philosophy, using studies with small population sizes, conducted over short time periods, often over either weeks or months While these studies are helpful at assessing the short-term benefits of ketosis, they fail to document the long-term effects of a ketogenic diet. A classic example of this is a paper that was published in 2017, documenting the results of 10 weeks of a ketogenic diet on 262 patients following a diet containing less than 30 grams of carbohydrate per day and an average of a175 grams of protein per day. Now, the researchers document how ten weeks of ketosis resulted in an average A1c decrease of 1%, an average weight loss of 7.2%, and how more than 56% of participants reduce their need for oral medication. These are all great outcomes. The problem is that the study was conducted in a small cohort over a very relatively short period of time. Now, in order to determine the true effectiveness of any diet you have to do two things: number one – study your diet in large numbers of people, which is tens or hundreds of thousands of people; and number two – study the outcomes of people following your diet over long periods of time – greater than approximately five years. Studies conducted in tens or hundreds of thousands of people over five plus years indicate that low carbohydrate diets promote the following disastrous outcomes: number one – increased risk for cardiovascular disease; number two – increased risk for hemorrhagic stroke; number three – increased risk for hypertension; number four – increased risk for atherosclerosis; number five – increased risk for diabetes; mortality number six; increased risk for obesity; number seven – increased risk for cancer; number eight – increased risk for all cause mortality, which is premature death from any cause. No matter how you slice it, low carbohydrate diets trick patients and doctors into believing that ketosis is an excellent long-term dietary strategy, when in reality the long-term consequences are often worse than the initial condition they were designed to reverse. Now the next time you consider adopting a ketogenic diet ask yourself a simple question: Are the long-term consequences worth the short-term benefits? Plant based news (PBN)

  1. WIN THE OPPORTUNITY TO STUDY PLANT BASED NUTRITION COURSE WORTH OVER $1200 WITH ECORNELL – www.plantbasednews.org/competitions/win-with-pbn

  2. There are far more people turning from vegan diets back to meat eating than there are keto proponents turning to veganism or vegetarians. Also there are more people experiencing weight loss, reversal of diabetes, Alzheimer's and some cancer related symptoms, than there are by people on vegan or vegetarian diets. Where are all the testimonies of people who's diabetes is being reversed by a plant based diet?

    As for the "science" behind the claims that LCHF, ketogenic or carnivore diets are unhealthy, it wouldn't be the first time that previous "science" has been proven wrong by new findings.

  3. Was hoping that this would provide some insightful knowledge, alas just the classic vegan mantra that Meat is Bad, unfortunately for the vegans have already lost 20kg cutting out the processed junk and eating yummy natural food.

  4. Here is my two cents on the issue:
    Some populations such as my own (arabs and amazigh who have been nomads aka hunter gatheres until very recently) have been consuming something similar to the ketogenic diet. We don't really produce many of the grains and the legumes you are talkig about, and they are not part of our diet. Actually, our cuisine uses a very limited amount of them.
    Yes our main dish couscous is made up of wheat, but that's all the "grains" we consume.

  5. Carbs are "the stuff of life"
    That said, this guy needs to ask Frank Tufano for some eyebrow implants. He reminds me of a Gooback from that South Park episode.

  6. These opinions are just that, opinions, without any citations whatsoever to his claims that a keto diet, in the long-term, can lead to chronic illness and death. This kind of fearmongering in a video that Plant Based News has put out is highly irresponsible at worst and was published as a clickbait tactic to scare people who follow this kind of eating protocol. When there's only one side of the conversation, it doesn't allow both sides to have an open and honest debate, which is biased, hyperbole and outright dangerous to have someone espouse such misinformation to your followers.

    Again, at worst this kind of video is irresponsible. Instead of listening to these fallacious claims against a keto diet, a diet that has helped tens of thousands of people in the long term, it would be best to stick to the science and listen to trained medical doctors who understand the facts about keto diets, and not listen to a person, as in this video, that doesn't have the full understanding of what the positive long-term effects are with this kind of diet.

    This doctor, Cyrus khambatta, clearly doesn't understand the basics of a ketogenic diet.

    Google Scholar links to the 39,900 scientific results which show all the benefits of a ketogenic diet: https://scholar.google.com/scholar?hl=en&as_sdt=0%2C10&q=ketogenic+diet&btnG=&oq=ketoge

  7. I ear whole food nothing processed keto diet and it has changed my life for the better down 80lbs and when I “cheat” I suffer the consequences #nsng

  8. Not only is the information in this video misleading at best , it's also dangerous advice. The whole video should be taken down

  9. Another plant diet freak. Tell my diabetic body that keto is bad. No more insulin injections, off statin drugs, bmi 15. Uh nope call bs on this clown.

  10. You say "The brain can only run off of glucose for energy". Then you say "(with keto) you force your brain into a state of ketosis, in which ketone bodies become the brain's primary fuel" This is just one of several inconsistencies in your lecture.

  11. Blood sugar level too high is a symtom of an underlying cause. In case of type 2 diabetes, the underlying cause is insulin resistance for the treatment therefore should be focused on, not the blood sugar level. In most cases, IR is due to too much fat inside the cells. The treatment is exercise (burning fat) and remove or reduce fat from your diet, in particular, animal fat and refined oil.

  12. The hilarious thing about many of these comments is that a lot of the keto supporters are saying different things regarding what the diet actually is. I think many keto supporters are so blinded by the weight loss benefits that they forget that the keto diet is extremely bad for your health. DO NOT try to tell me that a keto diet is healthy because it just isn't. Weight loss and helath are two different things. To all the people saying that there are many mistakes in this video; YOU ARE WRONG. Just because you think you think you are an expert about a diet that deprives the body of its preffered fuel doesn't mean youre right. This is a very reliable source for the facts about keto diets. I encourage you to stop taking the advice off chiropractors and the dr. Oz's of the world about how you should be eating, and do the research yourself. Do good research though, not something you read out of this weeks edition of fad diet monthly.

  13. Word up everything he said is 100% correct I've been studying weight loss diabetes and nutrition for the past 20 years I noticed there's quite a few thumbs down but obviously this knowledge is way beyond them and their understanding of the body and how fat in carbohydrates actually effect the functions of the body at the molecule level good video extremely informative

  14. So many people saying 'I went keto and I feel fine, so I'm gonna stick with it'… did you even watch the video? No one was denying that you will see short term improvements, and the video covers that in detail. Furthermore, you have no idea what you would feel like on a WFPB diet if you haven't actually bothered to try. Don't claim to be 'scientific' if your standard of evidence is nothing more than 'I stuck with the first diet that cleared up my condition.' Anyone can see improvements if they drop the standard American diet, and many diets, including vegan, will 'cure' or eliminate the symptoms of diabetes and a host of other ailments. The difference is that vegan diet will do so without subjecting you to the risk of long term adverse health consequences or premature death, and apparently, in the case of diabetes, will do so by actually rebuilding your insulin sensitivity i.e. actually curing diabetes rather than mitigating its symptoms, which is all that the keto diet is doing.

  15. Lol. Lecture from a vegan that looks like he could drop dead at any moment. I'm fairly open-minded, but have yet to see a vegan or any vegetarian baded dieter that looks healthy, looks lively, has a glint in his eyes or a bounce in his steps.

  16. I went to clinic today and the doctor told me I have high cholesterol and the number one thing I have to avoid to lower that high cholesterol is… Wait for it…. FAT! Yes FAT! I told him I already knew this and this should be common sense. We brought up the keto diet and both agreed it's bs. Yes my DOCTOR said the keto diet doesn't work. Again it should be common sense. He also said he had a keto patient and their blood cholesterol was at 12 he said he never seen anyone with high cholesterol like that until he saw this person's blood cholesterol.

  17. Dr. Khambatta – I have seen many videos on diabetes, insulin, ketogenic diet and related topics; however nothing comes anywhere as close to explaining the basics of insulin, its sensitivity, and its role in diabetes to a non-medical person like me than this video of yours. This video is as close any good medical textbook in it’s format including busting many myths sold by Ketogenic diet advocates and listing innumerable downsides of such diets. I have therefore, bookmarked this video and see it time to time to re-learn the basics, and why whole food plant based diet is the only appropriate diets for herbivores like humans.

  18. I was born with a pre-diabetic condition (hypoglycemia) and yes I tried the high carb whole foods vegan diet that he recommends with horrific results, I stuck it out for 30 days being told by an idiot with a PhD like him that I would adapt, needless to say that never happened.
    Where to begin debunking his BS, first of all that is NOT our food pyramid, not even close. The bulk of my diet by weight is dark leafy greens followed by non-starchy vegetables and then high fat foods such as nuts, seeds, and avocados. I eat a maximum of 1 small serving of meat a day. No keto expert that I have ever seen recommends such an insane food pyramid leading me to believe that this guy either has no clue what he is talking about or is choosing to be outright dishonest trying to pander to a primarily vegan audience.
    Insulin does promote cell growth, but the part that he is not telling you is that much of that growth is fat, hence people in ketosis have a reduction in Intramyocellular lipids that are one of the causes of insulin resistance. He is correct on one thing though excess insulin is VERY bad for you and in ketosis we have no such excess.
    High cholesterol? Then why do most people on a clean keto diet LOWER cholesterol? What planet does this guy live on? Even other vegan doctors admit that the keto diet often lowers LDL cholesterol and body fat.
    Fat triggers insulin too, that much is true, but it averages only about 2% of what an equal amount (by calorie not by weight) of carbohydrates do. My insulin resistance improves on my keto cycles, I was not sure what he was talking about until he mixed in the SAD (Standard American Diet) Yes clearly that part of his point is correct which is why we don't mix large amounts of simple carbs and fats, but adding a grain of truth does not make the rest of that lie true.
    Insulin resistance is a combination of factors, including carbohydrate consumption (especially refined simple carbohydrates) and intramyocellular lipids, that is why in ketosis we restrict the carbohydrate consumption and burn off the Intramyocellular lipids through exercise, thus improving insulin resistance, yes that really does work.
    I have been doing this for years and I never once heard any expert in the field of keto say that there was no use for glucose in the human body, he is clearly playing to a strawman argument here which is of course a well known logical fallacy, I expect no less from a vegan activist.
    OK on the brain argument that is mostly untrue, most of the brain can in fact run extremely well entirety on ketones, even better then glucose for most, and the small portion that cannot can get all of the glucose it needs through the process of gluconeogenesis, the fact that he fails to point this out is proof of his intellectual dishonesty or ignorance you take your pick.
    On those side effects that he listed, sure if you eat a piss poor keto diet you can have all of those issues, but the same can be said for any diet, I have none of the above in fact I feel great in ketosis, in fact my acid reflux went away entirely as did my symptoms of hypoglycemia, so it cures or treats some of the conditions that he is accusing it of causing which is laughable to say the least.
    OK here is the kicker, people in ketosis have more disease, yes there is a study that points to that, but they did not take into account that many people who use the ketogenic diet are using it to treat a disease they already have like myself. Which is equivalent of saying people that take medicine are more likely to be sick, it should go without saying that this is a stupid argument at best.
    OK that is enough of his stupidity and dishonesty for one day. If you believe this guy my God have mercy on your poor soul, he is clearly dishonest or stupid as I have clearly pointed out here, my results on keto have been superb and I am not any kind of activist nor am I trying to sell you anything, believe whoever you like.

  19. So you're telling me that eating leafy green vegetables, avocados & healthy fats, and wild caught salmon everyday is going to destroy my health? First learn what the healthy keto diet is then talk about it. Your twisting the information to fit your agenda.

  20. If low carb diets kill you Doctor
    Why would we eat veg probably the lowest carb foods you can find apart from meats ?

  21. Keto has saved my life. Every single aspect of my health and vitality has improved. I’ve also lost 50lbs in 90 days. 3x shirts to xl shirts. Psoriasis gone, migraines gone (used to have 3 per month), feet tingling gone, blood pressure improving, blood sugar normal, brain function that startles me, sleeping 2 hrs more per night, and on and on……..how is this a bad thing.

    Order biggie fries and onion rings with lunch and no one bats an eye. Say your eating Keto and everyone tells you your going to be dead in six months.

  22. Sorry dude – you look like you are half way to the grave. My business partner is vegan, overweight and looks 10 years older than he really is. I am experiencing the best health of my life by eating a Keto diet. Best wishes.

  23. You sir are wrong, FACT. Now because I used the word fact I must be correct. Mind you , you do look like the picture of health.

  24. I call BS. I have to go to work now but I will dismantle your argument. I can't believe the amount of lies here. You didn't even mention gluconeogenesis. You don't need carbs for glucose. The body can convert proteins into glucose. Why did you leave that out? By not fully putting the info out there, it's just as bad as lying. Neways I will be back to break down all your points.

  25. So I just watched this video (to be polite) and here’s what I say:

    1) there is no mention at all of glucagon, which work as insulin’s opposing force, which is catabolic (versus insulin’s anabolism). So there is no mention of how one can control weight, which is why many people adopt a ketogenic diet and achieve weight loss.

    2) the amount of carbohydrate restriction varies from person to person though 20-30g daily is a generally advised target (some are more or less sensitive to carbohydrates).

    3) the insulinogenic effect of protein does not get mentioned at all, especially how much insulin is produced when one eats protein with carbohydrate (versus with fat). See the work of insulin researcher Benjamin Bikman for more about this effect.

    4) if it is true that fat spikes insulin INSTEAD of carbohydrates, then that needs to be proven, and not merely told to us. This facet is one that really needs to be biochemically true if it is to be touted as fact, otherwise the ketogenic paradigm or the promoted plant-based paradigm falls completely flat. So I would need to see data that shows that discrete ingestion of each macronutrient in a healthy person affects insulin secretion in the way suggested. If the video is incorrect, this is the most egregious example of twisting the science I’ve heard.

    5) If the presenter is a PhD, I would assume he should understand what “essential” means in a nutritional context. This is where he gets funny with language. Carbohydrates cannot be synthesized in the human body, that’s why they are not essential.

    5a) he does not ever mention the body’s capability to create glucose from fat/protein, gluconeogenesis. This further underscores the concept that carbohydrates are not essential as a dietary source for human health, but VERY much is useful for SOME biological function, primarily erythrocytes. This brings me to…

    6) the oft-touted notion that the brain NEEDS glucose to function properly. While it is true that the brain cannot use fatty acids, the ketones produced by fatty acid metabolism, however, CAN be used as a fuel source. There has even been one recent study where dementia patients regained some cognitive function when given MCT oil (the working theory of the study being that the demented brain can no longer effectively use glucose as a fuel but can still readily use ketones, thereby feeding an otherwise starved brain, leading to the positive findings).

    7) the list of possible side effects, which can always be associative versus causal, which was not mentioned.

    8 ) if there are no long-term studies of the health benefits of a ketogenic diet, then there cannot be any clinically exhibited demonstration of any long-term ill benefits either.

    8a) the one 10-month study used to suggest there are no long-term studies actually is ongoing and has been published as a 2-year study. Conversely, are there many studies suggesting the long-term benefits of plant-based diets?

    9) there’s no easy way to test fasting insulin at home, so I’ve not heard of any keto person suggesting that they do at all, let alone often.

    10) while the normal oral glucose tolerance test would be a good way to determine diabetes risk generally, it doesn’t go far enough, as demonstrated by Joseph Kraft, who tested using the oral glucose tolerance on over 10,000 people and expanded the test time to 5 hours, showing that lots of people who had normal blood sugars still had very high levels of insulin.

    11) the etiology of insulin resistance wasn’t mentioned (as widely understood as the body’s exposure to chronically elevated insulin levels, primarily through poor diet), I’m guessing this was due to the presenter’s statement that fat raises insulin even more than carbohydrates (again this notion is odd since insulin’s primary role is to control blood sugar, not blood lipid).

    12) the specific biomarkers that are typically associated with cardiovascular disease were not mentioned (HDL, triglycerides, CAC score; or even the antiquated ones like cholesterol or LDL). All he said was that one can increase risk of these things on a keto diet. But again, are these causal or associative? How strong or weak if associative?

    I’m sure there are scientifically sound arguments against a ketogenic diet out there, but this video wasn’t one of them. This came off as scare-mongering propaganda, with about 80% fact and 20% dubious information.

  26. 1.We are all born in ketosis.
    Mothers milk is only about 5% protein and the rest fat.
    2 When we go to sleep and get hungry we go into ketosis or we would die.
    3. The ketogenic diet for non epileptic people is simply a method to help adjust your body to lower high amounts of insulin and start burning fat for fuel.
    4.The ketogenic diet is simply a tool to ultimately reduce hunger naturally to fast in a limited fashion.
    5.Ketosis is just as important as insulin and both must be kept in balance.
    6.The brain can get all its glucose from the liver.

  27. KETO works, prove me wrong, this guy cherry picked his points. He has also been in some garbage documentaries as well. YAWN…

  28. I think keto can work in the long term for some people it depends on your genetic make for fat burning. I tried keto on and off for 2 years without success. I didn't get the abundance of energy that everyone talks about. I was strict 30g carbs or less everyday and would feel great for around 2 weeks and then go downhill from there. Only thing that brought me back was eating carbs. Tried everything – electrolytes bone broth nothing would work. I figured it was low blood sugar causing this. I also noticed some of the symptoms he described in this video, constipation, weakness and inability to focus and concentrate. I've just move over to a whole food plant based diet and feel alot better, i've gone back to doing things i'm passionate about again and i think this is a better long term strategy for me. But some people do thrive on keto if you eat clean, don't eat bacon and cheese everyday just eat good veg/berries fish nuts eggs dark chocolate etc and you'll be fine if your body likes it. If you feel fine stick with it we're all different!

  29. So Dr Bernstein, type 1 diabetic since the age of 12, pioneer of home BG monitoring and the basal bolus insulin regimen , and has been eating high protein and less than 30g of carbs per day for decades, still treats diabetics at his practice while over 80 years of age……..How long term do you mean?

  30. This is fake plant-based news.
    This clown looks the camera in the eye and just lies.
    What a bunch of bullshit!

  31. Went from 400 to 260 used to have alot of heart issues and depression and anxiety and low self esteem, used to want to eat every 2 hours and felt like i was starving when i went plant based to all the supplements i needed ate and ate and shot up to 400 pounds. Heard about keto and gave it a shot with fasting drop from 400 pounds to 260, its something i really love as a diet and i am a big believer in it my cholestrol ratios and numbers are great have no heart issues anynore and no hunger and its something i been doing for close to 3 years also haven't been sick or anythibg like that for 3 years to and dont take any meds. Everyone is a different and there are different ways to get healthy in the long run. I say what ever diet you choose just make sure your insulin isnt really high make sure you keep it lower and dont eat junk food you will lose weight and improve your health. We all are doing different paths and things to get health but we all are striving for the same thing, keep doing what works for you its your body its your life.

  32. Let's bear in mind one fact. Your liver already makes all the glucose your body needs. There is no reason whatsoever to eat any carbohydrates. Period. There are NO essential carbohydrates. So, why are you eating them – because you were told to eat them, you grew up eating them, the ADA, AMA, FDA, told you to eat them, the vegan gurus told you to eat them, your religion told you to eat them and since Ansel Keys/Senator McGovern, your doctor told you to eat them. It is 'just a coincidence' that during this after Ansel period diabetes, obesity and heart disease have skyrocketed, right? Every farmer can tell you, if you want to make a mammal fat, feed it carbohydrates. People have been keto for millennia with no ill effects. These facts should inform your debate and yet, we get this rubbish from someone who should know better but doesn't.

  33. Insulin is a fat storage hormone see Lipohypertrophy

    Insulin injection sites are rotated for a good reason, FAT WILL BE STORED AT THE INJECTION SITE

    Here we go again!

    No one diet is best for everybody, but he is promoting a plant only diet. This may work for some… But KETO/palio is much more sustainable as a life style, NO it is not a fad diet! Until about 150 years ago, low carb high fat was the human normal diet.

    The explosion in obesity, diabetes and heart disease is likely a result of low fat, processed food, and a 1000 percent increase in sugar consumption in the last 120 years. Low fat/high carb is killing us!!!!!!

    Eating starchy plants is a recipe for INCREASING insulin production and for continued hyper-insulin diseases.

    Intermittent fasting (1-2 meals a day within an 8 hour or less time) has demonstrated insulin lowering benefits.

    His data is dated and flawed. Most advice from vegans is from based on consensus data, not on science based studies.

    IE: “We agree that earth is flat, so it must be!”

  34. There are quite a few fallacies in this video. Coming from a background of being Vegan/plant-based for 2 years, I know the argument of both sides. The first issue I have is the statement that you believe the Keto advocates are against insulin and that insulin makes you fat. The truth is, we are concerned with the Insulin Resistance due to the prolonged years of eating a combination of fats, carbs/sugars, and proteins.

    It’s not insulin itself. It’s the insulin resistance because the muscle cells are no longer communicating. Also the fact that you say that Keto only limits to 30 grams of carbs per day. This is not true. With Keto, we recommend to stay below 50 grams of carbs, but you failed to say if these are total or net carbs.

    With the Keto, you are tracking your NET carbs. So your total carbs can be around 70 grams, but your net carbs could be under 50 due to the higher fiber content. Keto recommends good sources of carbohydrates from 7-10 cups of salads, cauliflower, broccoli, bell peppers, as wells as fruits from berries and olives.

    So then you talk about how Keto advocates label the “carbs are not essential nutrients” as if we are saying we don’t need glucose. That is not true. The reason why we say that carbs are not an essential nutrient is because our bodies can make glucose from a non-carbohydrate source. This is called Gluconeogenesis. Essential nutrients only means that a nutrient that cannot be made by the body.

    The top Keto experts understands that your body needs glucose and it knows how to make just enough to keep your body operating. Most vegan advocates keep saying that it’s a high protein. NO! this is not true and the mathematical don’t add up. A 3 oz protein for 1 or 2 meals a day is not a high protein diet and you’re not sitting around eating loads of cheese either. Lastly you show no reports or evidence of any keto long term effects. Sorry, but the fear tactics won’t work if you’re know what you’re doing. Research on a low carb study is not the same as a keto study.

  35. Ok. This guy tell that glucose is the only fuel for brain. Actually my experience is quite opposite. After having keto diet. My brain is much clear and sharp than it was. Keto diet has been used for dealing with nerosystem dysfunction since 1970s. And it was proven to be useful as a treating diet. Where your knowledge comes from?
    Let me use your way to speak.
    FACT: Brain likes to burn Keton. And the first benefit from Keto diet is clear brain.

  36. Ketogenic, Atkins, fasting, been around since 2000 BC & Moses times, & 400 BC Greek physicians knew about it. Conflict comes from govts, economics, pharmaceutical companies, doctors media all marketing their products.
    Large companies pushing cereals and foods full of sugar, conflict of interest from food & medical industry. Same with Seventh-day Adventists they're pushing their Sanatarium stuff as well… it's all about the money folks, bc you don't make money & gather tax from people not eating.
    Alternatively you could use self control and reduce your dietary intake by 30% and live longer.

  37. Wow! How can someone say so much bullsh*t so confidently?! Humankind has been consuming animal products for millions of years – how can anyone think they are 'bad' for us?!

  38. This is typical of YouTube. He’s on a plant based diet so he’s going to push a plant based diet and try to sway the keto diet people towards his channel. All people please listen. Regardless of plant based, keto, paleo or carnivores. Not every diet will work for everyone. Everyone is different. But whatever you try listen to your body and your labs. If you feel great and your labs are improving that’s the diet for you.

  39. Problem with most keto Nazis is that they think it's perfectly fine to load up on crap like bacon and sausage. The diet is designed that you get your fats from healthy sources like avocados, olive oil, coconut, nuts, etc. Also, you don't need that much fat in order to be healthy.

  40. Eat healthy foods and you will be healthy. It doesn’t have to be complicated. Fruits, vegetables, protein, and fats in moderation. Balance diet with adequate exercise/physical activity and you’ll be good. Somehow an extremist moron will find some way to disagree with this statement.

  41. I am confused as hell!! I am not defending ketogenic diet but for now I think that problems start when you combine high fats with high carbs foods ……. I am still looking for the truth

  42. Stayed in ketosis for 9 months, worst mistake I ever made …
    Gave me psoriasis, provoked autoimmune response, damaged my stomach, gave me food intolerances…
    I was totally bought buy the keto gurus blaming carbs for all evil…
    How wrong I was…
    The more I studied trying to work out the more I realised how completed illogical it is…
    Keto is a short term survival technique when your body goes into a stress mode waiting for its main fuel source to come back…it's a starvation back up mechanism which can have short term benefits when ketosis is provoked through REAL fasting with water or intermittently…
    But long term ketosis is biologically unsound and deprives you of all the essential vitamins mineral phytochemicals antioxidants and even unfound nutrients found in carbohydrate sources…which are the most abundant in nature…
    We have taste receptors for starch and sugars…we were not meant to eat pounds of butter and pots of coconut oil and flesh for the majority of our diet…
    All the blue zones in the world live off a high carbohydrate diet, they live the longest, are leanest and are the healthiest…
    Keto is a short term fix for epilepsy or other serious conditions with the cost of long term unhealthy side effects

  43. a few questions. what is the normal range for non type two diabetics on glucose tolerance test and, what is it for diabetics? second, have you ever seen or has your program ever changed the range of a type 2 diabetics glucose tolerance test from the diabetic range to the non diabetic range? please be specific. thank you in advance for your answer

  44. ketogenic diet goes hand in hand with intermittent fasting , because fat burns slow , you feel full for long period of time. and fasting has been found beneficial for generations and hundereds of years, people who eat carb rich foods cannot do fasting , carbs makes you eat more carbs and you can never escape the vicious circle of eating and eating and eating carbs until you die

  45. I love this guy. He and Drs. Klaber. Barnard. Greger. Esselstyn. Mcdougal. Colin Campbell. They’re the ones I trust most. Vegan baby! New to it and blood sugar dropping. Meds can’t compete with this diet. I eat about 200+ grams of carbs a day. Some avocado a few nuts all Whole Foods otherwise. I’m eating a ton and never feel heavy or slowed down. I still crave meat but I’ll give this 90 days I’ve done 35 before and lost almost 20 pounds. For some reason I didn’t think it was enough and quit. And partly because vegan is difficult.

  46. I am truly sadden by the fact that even though most people have a general understanding of what ketosis is …… here comes a plant based advocate who spins the keto diet into a negative light. …… People if you listen closely to what he said, hr is simply giving to ways of resolving your issues, keto vs plant base in which he laid out some facts and then he sprinkle some lies in your mind about keto to make you doubt your positive results with keto…….. this is an example of how someone who has an agenda work on putting doubt in the mind of the people!

  47. Oh my goodness, you guys never stop with your errors about ketosis and more importantly healthy fats found in nature which Man has eaten since God create him!
    No, Ketosis doesn’t demand the total avoidance of any of those foods if you’re don’t need to for health.
    No, eating mostly healthy fats long term doesn’t and can’t harm your health but causes health!
    No, true and healthy Keto doesn’t state insulin is bad but rather, as you yourself say, excessive insulin is!

  48. The keto commenters crushing this video. No eyebrows, bulging eyes and lines. How old are you? Not exactly a role model for vegans.

  49. Who are you and what are your credentials. Keto works for me. In addition to controlling diabetes, I have very little amount of inflammation. No one is saying insulin is bad, but excessive insulin is not good. Give us the specific research so we can read it.

  50. Your agenda is preaching pure vegan. You are delusional. See other people how look and feel after few years on frutarian and pure vegan diet. I am on keto on last two years and all my blood test are great. I fell great. I have lots of stamina/energy. I was on keto many years back and at that time I was at my peak of my health. Pure vegan is not the ideal diet. A balanced keto (lots of vegetable, quality fats and moderate protein is the key). Depending on age and goals it can be adjusted but pure vegan is non-sense.
    The moment I switch to high carbs from fruits I am like a vegetable, with no energy and hungry all the time.
    You mention studies, lots of studies are just manipulation of $$$$ and you failed to mention named of the studies or who funded them.

  51. Can you give me the links to those long term studies you mentioned, but didn't actually cite. I can't help but notice your description doesn't provide links to your "research"… mostly just links to your veggie boy merch.

    I'm on keto. I've lost 45 lbs, lowered my A1c from 6.6 to 5.4. …and I feel pretty good.

    As a type 2 diabetic, I keep a close eye on my glucose when I have a cheat day. As far as I can tell, my insulin sensitivity has improved quite a bit. I pretty much have to eat a bucket of Halloween candy to break 200 these days.

    It did get worse after I fell "off the wagon" for a bit. I feel like you might be unintentionally misleading your viewers in that particular area. Still… If there are studies that show long term problems with this fairly new health approach, is love to take a look at them for myself.😉

    I'd love to just take your word for it, but frankly, sir, you look… umm… how do I say this?… unwell.

  52. Very well said! The ONLY diet which leads to great health and longevity is whole Foods plant based diet!

  53. Yes he should have cited specific studies related to his statements. If you disagree with what he says because you agree with the Keto
    diet and promises about it, thats' your choice. Please however act like an adult and refrain from commenting about his looks, that is
    juvenile and unnecessary. For people who believe consuming 70-80% fat is healthy, or consuming 70-80% carbohydrates is healthy
    (as I do) wait to see the long term (over a year) results. Studies do show that a lot of fat in the diet does increase insulin problems as well
    as raise hormone levels. There needs to be many studies showing long-term positive studies regarding any benefits of Keto. The video from Mic
    the vegan does cite many studies regarding the problems with Keto. I believe, as many people do, that we are designed to thrive on high healthy plant carbohydrates. Keto believers think that they should thrive on "healthy" high amounts of fat. Noone wants to hear or read any information that criticizes their choices, especially with proven data, and people get very defensive when its' done. namaste', rachel

  54. Keto doesn’t disallow anything. You have a macro target in addition to calorie surplus or restriction your goal is to pick foods that fit those macros while getting all your micronutrients.

  55. This guy breaks out of Area 51 and now wants to condemn keto. Anybody fact check the studies he’s getting this info from?

  56. Good video! But you wanne tell me as a prediabetic my glucose meter won't spike to 140+ when I eat grapefruit, cashews, oats??🤔 (I list these carbs as they are lower carbs than the bad ones). If so I will switch NOW from my HF diet

  57. This isn't hate but genuine curiosity since I'm sceptical about going vegan. When I eat carbs I cramp and bloat but when I eat animal based I feel perfectly fine, good even. I've noticed that every long term vegan gets matte grey skin and these lifeless sunken eyes, meanwhile meat eaters' eyes look bright and their skin looks glowy and plump, so why is that? Shouldn't your health reflect on the outside? Again, I'm just going off what I've seen, this isnt hate and an answer would be greatly appreciated.

  58. Please provide your references.

    I find a lot of “low carb” studies with 40% carbs are used to summarize Keto diets with under 10% carbs. Low carb and Keto are not the same things. A low carb diet with 40% with fat is just dangerous.

    Seed oils are not healthy. Seed oils are not part of a typical Keto diet.

  59. So many people in the low carb community have disinfo with no proof, especially regarding human anatomy and physiology. Looking at every body system and how they work together it is clear that high carb, low fat, whole food plant based is the species specific diet that actually works with our body. Don’t ignore body systems like the lymphatic system, nervous system and digestive tract. It is clear that we have almost uncanny similarities to frugivors like apes and monkeys and herbivores like horses. Not carnivores like lions or omnivores like bears. Diseases like atherosclerosis and Alzheimer’s caused from high cholesterol/ saturated fat cannot be seen in natural carnivores and omnivores but they will show up in frugivore’s and herbivores as soon as saturated fat/ cholesterol is ingested into their diets. That alone proves we are plant eaters only! Just because we can eat dirt doesn’t mean it is a food biologically created for us to eat. Same goes for animals bodies and by-products. Just because media says low carb is the best diet and you have now created an identity around it doesn’t mean you have to feel personally attacked when someone has better findings for a better diet. That’s called cognitive dissonance

  60. No sincere advocate of the ketogenic diet would ever assert that "any amounts of insulin are bad". Fact 1/7

  61. Claim 4: "While this is technically true…" – yes, it's true. The brain never runs off ketones on a ketogenic diet! Glucose is essential, but it does not necessarily have to come in form of an exogenous molecule, but the body can synthesize Glucose from proteins through a process called "Gluconeogenesis". That way, the brain can get its share of glucose and remain healthy.

  62. wow!!!!!!!! I was almost believing in the long term benefits of keto diet!!!!!! Thank you so much for this video!!!!
