@@lennonpaiva7058 Same here, great analogies indeed. Problem is when someone can't even understand simple analogies. (I've had it happen many times sadly)
i applaud you sir for raising awareness of this on your channel consistently. its an extremely important issue , keto approach is being used very widely in the UK currently and is endorsed by the NHS Royal college of GPs

The problem is this simply isnt true. Greger is confounding temporary phenomenon with the underlying pathology. 'fasting' for a week results in exactly the same temporary response to glucose. The question is what happens to *actual insulin resistance* on a low carb diet or fasting? It improves. Greger doesnt address this. A recent study by the US military found that a three month Ketogenic diet found that *Insulin resistance was improved by 48%* compared to controls. I wonder why Dr Greger doesnt mention that?
My mother definitely lost 25kg and reversed her type 2 diabetes. She has done the hard work, and enjoys high carbs here and there but has found Keto food to be way more fulfilling. Yes her blood sugar level rockets because she was sensitive, but that was only at the start of reintroducing carbs - people would rather tare it down than believe a human will adapt to it's conditions. High BGL should not be the aim, and using it as the argument is far from Keto and just stupid.
Look up all the 2012 + articles in the citation list you provided. The most recent articles provide evidence in favor of a ketogenic diet. In particular Hussain et al. (2012) shows better outcomes of the ketogenic diet for patients with type II diabetes than calorie restriction. Hallberg et al's (2018) study is the same. All the blood assays show very strong response to a ketogenic diet and improved outcomes. Both these studies have decent sample sizes +300 patients with good control populations on which to compare research outcomes, The video rests much of its thesis on the results of Perry et al. 2017. That study shows that binging on a high fat food generates negative impacts on glucose sensitivity. The methods of this paper are limited - only 15 participants - all of whom are healthy and do not have type II diabetes. However, if the paper is read critically there is also a major flaw in how this video interprets the Perry et al study. Simply click on their Table 1 data to see the composition of the so called "high fat: diet fed to patients as the treatment. Indeed, it has a lot of fat (440 g worth and nearly 6000 cal). It also had an incredible amount of carbs - 192 g. That is 4 x the daily carb allowance of a low carb diet and 8 x the allowance of a keto genic diet. Obviously the outcome of the study could be just as readily (and mechanistically more likely) ascribed to the massive carb intake with the treatment as it could to the fat in the diet. So the thesis espoused in this video has problems. Regarding the esteemed MD and star of the show, nobody should listen to what Greger has to say.
When he started using cars as an analogy instead of talking more about the science, I felt like there was something hugely missing, like he was just talking about his own hypotheis and not what data shows. Thanks for doing the research
@@AndyThomasStaff I found this comment hidden, somewhere here, as a reply to someone else and copied it here because I didn't want people not to come across it. But thanks!
It is about insulin sensitivity. Fasting and low carb increase insulin sensitivity dramatically. These studies look at the very short-term effects of eating fat. They are almost useless. The game is about adaptation over several months. The body adapts to low carb healthy fat diets. You don't really see the full spectrum of benefits before a person's body has fully fat adapted. This video is a prime example of simplistic thinking and ignoring nuance.
I can say that when I first started to add carbs back, I would notice diabetes symptoms immediately via dry mouth and excessive urination. It would go away if I worked out that day. A few weeks in and the symptoms are mostly gone even when not working out
You eased you system back slowly, using exercise. Good work! I'm going back to a whole foods diet, but this time trying to be more careful about not taking in too many carbs. Both fat and carbs are easy to over do.
it's called the Randle Cycle. it protects your cells from glycative damage, at the cost of red blood cells (and eventually atherosclerosis, as there's only so much damage the red blood cells can absorb). the Randle Cycle activates whenever you mix fat and carbs in high amounts. fat is essential, carbs are not. the choice is simple.
@@uberneanderthal from wiki I gather both carbs and fatty acids try to out trigger each other so I can imagine that a meal with lots of fat and carbs might be a bad idea if one of the two will circulate in the blood while the other is being used.
@@Rene-uz3eb correct. but note that only fat is stored inside the cells, while blood is stored exclusively in the blood until it can be quickly used. the entire purpose of the Randle Cycle is to protect the cells from glycative damage. remove glucose (i.e. all carbs) from the diet, problem solved. also it doesn't matter if the fats and carbs are in the same meal, as they can take up to 72 hours to fully metabolize.
@@uberneanderthal the Randle cycle is stil being researched, my interpretation is that it's simply about the body choosing to process primarily one fuel at a time rather than allowing both at the same time, which would require say additional balancing methods because you can't just double the energy supply if you have both fatty acids and glucose available. So if you eat a 1000 calories meal, whether those come primarily from fat or half carbs and half fat shouldn't really matter, the body will absorb one or the other first from the blood and then switch to the other. Technically if the first was fatty acids, then you might think the extra time the glucose stays in the blood is detrimental, but at a fixed absorbtion rate it turns out to be the same if you had 1000 carb calories or 500 fat + 500 carbs. So I think the importance of the RC is overrated.
I agree with this 100%. I followed Dr. Barnard's approach after being told I was prediabetic and was able to reverse it. I decided to follow keto a few years later and became prediabetic again. I also had high cholesterol. Currently working on fixing both problems.
I just typed the same story as a reply to the comment above. Low BP my whole life, I went keto and it kept going up across the years on it. recent;y reverted to a Macro diet, and boom. BP dropping back to normal.
I think this happened to my neighbor... She went on the Atkins diet for a while. Soon after she was a diabetic and put on 2 insulins. I always felt that it had something to do with it.
Oh my goodness! I thought that things like that could happen but I had never heard a story of it happening before! I hope she is doing better on some other diet now.
@Danny J. I understand what an anecdote is ;) Based on the science in this video, me thinking that it seemed connected to her stretch on Atkins, seems possible.
Your neighbor must have been overweight if she attempted the Atkins diet. BEING OVERWEIGHT CAUSED the type 2 diabetes. It's due to fat blocking the cells that otherwise would absorb the carbs/glucose that the body typically uses as fuel. The glucose remains in the blood stream, and becomes SYMPTOMATIC for diabetes but does not CAUSE diabetes. The fat does. So keto is the worst case scenario for a diabetic patient. Also, it takes YEARS trio develop type 2 diabetes......
@@myggggeneration She was maybe 15-20lbs overweight. Went to the drs regularly. Walks with a walker due to MS. Went on Atkins. Lost some weight. Went off Atkins... Not sure exactly how much later, but I know it was less than 4 months, at her next appt she was put on 2 insulins. She's also not doing well on the insulin. She doesn't eat sugary foods often either. I personally don't think the Dr should've went right to insulin, etc... but that's a whole other subject.
4:50 I get your point, but it's important to define what is a "normal diet", because the argument is said that said normal diet was what caused it in the first place. But I'm with Greger on this, I've helped my grandfather with diabetes simply by reducing his fat intake, so I know it works.
@@heartdragon2386 However, I think that is what Dr. Greager means by a normal diet. It is the most common diet in America and by that standard it would make it "normal" for American's.
High fat isn't really keto. Keto done correctly like Dr.Berg recommends is eating 7-10cups of veggies and after being on cleam healthy balanced keto not too much protein either he says moderate amount from only grass fed animals you can cut down on fat. Ppl think it needs to be extremely high but it doesn't need to be
One of the factors of insuline resistence is something called intramyo cellular lipid, which means fat inside the muscle cells. The bodies preferred fuel for the muscles are carbs. Insuline is used to "unlock" the muscle cells and let the carbs get stored in there (as glycogen). A high fat diet makes fat get into the muscle cells, which prevents the insuline from working, sort of like gums in a lock. When carbs can't enter the muscle cells, it stays in the blood, which results in high blood sugar, but the reason for it was not the carbs, but the excess fat. Removing the fat, makes the insuline work properly and lessens the need for it.
MindVersusMisery that’s why you don’t mix fat with fructose. The extra channels that open up in the presence of fructose and insulin will draw in protein or fat as well. Those channels are generally resistant to fat when insulin isn’t being spiked.
This video seems to be the "missing link" in the rabid discussions on LF vs HF diets in relation to diabetes. This should not be a 4 year old video. It should be front and center.
Rubbish. I’ve been on Keto for just a few months, reversed my type two diabetes and I am no longer taking insulin or medication, my A1C went from 9 to 5.7 and my blood sugar is always between 70-85. Funny how all of the critical comments of this video are hidden under the “newest” filter while all the bot comments are the first shown hahaha.
I was a Vegan for several years, through time I found myself constantly hungry, I was eating all day long chasing my hunger, gaining weight, getting depressed, I began to realize that all the fruit smoothies, pastas, rice, oatmeal, breads, cereals, potatoes and the vegan processed "meats" which were the mainstay of my diet (coupled with the veggies) were making my insulin go through the roof, and causing havoc on my system metabolically. When I switched to a keto diet which is high fat, medium protein meats, eggs and seafoods coupled with the veggies, and lower carb fruit-like the berries my whole world changed, my hunger ended, I lost 25 pnds in six weeks, I feel amazing, and would not go back to high carb grains, starches and fruit for anything.
I am vegan, and my hunger goes away in the middle of my meal that i fail to finnish, and i have to force myself eating a little bit more, fiber stops you from hunger, so personally, i dont believe that you ate veggies(or too few), only full proceesed food, like white rice, smoothies, pasta, and vegan junk food, i eat a whole salad plate, legumes with brown rice for dinner, whole oatmeal with banana and berries, with avocado and toast in breakfast, launch the same as dinner in less quantities, i eat a ton of fiber in the diet, which makes so that sugar never spikes; i think that your problem is never eating enough fiber and too much preceess and refined food, even if its vegan, it is bad and not recommended, french fries are vegan and still incredibly bad for health.
@@Voltaje_YT What you are saying about 'fiber' isnt true, my dad has diabetes 2 and it doesnt matter how much 'fiber' he eats there is zero difference between brown and white rice, whole wheat or white bread when it comes to blood sugar spikes, and all of these foods push blood sugar through the roof, I know this b/c weve done many comparisons with my dads glucose tests one hour later when he tests his blood sugar, also, being on a STRICT hardcore diet like you are outlining is not sustainable long term, I know b/c I started out great and ended not great at all, I got to the point of being constantly hungry and grazing all day, I was hurting myself and in denial..
Have a friend who has been doing keto for a year and has lost a lot of weight but she has new issues like low iron and the inability to handle taking vitamin C that she didn't have before keto. Then there is the issue of increased cholesterol levels from all the high fat animal products that folks who do keto seem to not want to think about. On a side note Type 2 diabetes is highly preventable. Our son was born Type 1 and on insulin beginning as a baby. His pediatrician was SDA (Seventh Day Adventist) and we had just become vegetarian in the 70's (which was vegan/plant based is called today) and she noted abstaining from animal products was best for diabetics and non diabetics.
low iron means your friend isn't eating enough red meat. and yes, you need very little vit C on a keto diet, precisely because carbs and vit C compete for the same GLUT receptors. the fact that keto requires less vit C is one of its many benefits, as vit C produces oxalates that are damaging to the body. and cholesterol is not an issue, unless it's too low.
T2D here. Doing Keto and IF. Took my cinnamon and Berberine at bedtime because my sugars just haven't been falling, not even after eating nothing since 4pm the previous day. The Dawn Phenomenon they call it. Finally, my blood sugar came down 40 points. I went ahead and has my coffee with just cream, holding off until breakfast for 3 more hours. Checked my blood sugar before breaking my fast. Clear up 50 points. I went on my walk. Still ugly high. I'm here to for report that the Keto diet, even with IF doesn't always work. What it does prove for myself is that fat is the culprit. Time to try something else.

@@debramccawley1714 Huh? So your reply to my sharing how my experience is different, is to tell me that everyone is different? Not sure what that adds to the convo. But ok.
@@debramccawley1714 You are one of the "If it worked for me, it means it HAS to work for everyone" people. And, "If it doesn't, it means they did something wrong." Okay, enjoy your world.
Still 6 years after, and I as a T1D disagree, but with a plant based keto diet. I even made it through the police academy in my country and aced every physical test without suffering any complications in the process or even a year after.
Type 1 and type 2 are so completely different though. My type 2 is disappearing with one meal a day fasting. Doesn’t seem to matter how much I eat as long as I don’t snack continuously, keeping my body in insulin production mode.
Also, I'm sure the plant based diet has less saturated fats than a regular diet, which it's the key factor here. The ketogenesis diet promotes the comsumption of FATs, which in animal products tend to be saturated, different from let's say avoicado fat. Glad to read you're doing well.
Keto lowered my HBa1c from 6.2 to 4.5. Raised my HDL and lowered my triglycerides. Lost weight effortlessly. It’s been five years and I would never go back to being bloated and hungry all,the time. Plus the low carb doctors in general appear to be in much better health than the vegan docs who age quickly and look very frail after 30-40 years on a strict HCLF Whole Foods diet.
Every word you said is absolutely false. Literally the exact opposite is true. There are no old keto docs. They’re ALL dead younger than vegan docs. ALL!
@@thedigitalemotionyes he is. I know a lot of people who don’t have diabetes anymore. No one eats sugar when they’re doing keto. This guy doesn’t make sense. If you never have carbs again your blood sugar won’t go up. People don’t need carbs. Dr Ken Berry proves this dr doesn’t know what he’s talking about. Dr Shawn Baker looks healthier than this frail looking so called Doctor. He doesn’t look healthy at all.
@@omadjourneyWatch the videos by Dr Nadir Ali (Cardiac Surgeon). He explains the metabolic processes in Diabetes that need to be fixed, you may be able to come off Metmorfin within 12 weeks with a mix of dietary changes and exercise. Obviously you should talk this through with your Doctor first so that he can ensure your blood sugar and insulin levels have stabilised!
from your name i assume you are an anthlete, so you burn as much as you consume, so yes, for you a lot of carbs is not as bad as for many other people that spend most of their days not moving much. i've been eating a lot of crap food in the past (all that crap food, like nachos, icecreams, cakes, etc are very rich in carbs usually), and it made me pre-diabetic. i stopped for few mnths, sticked to healthy food - meat, fish and veggies, and said no to pizzas, pastasm sugar and bread, and i can feel much healther now and my weight has been on decline. this video is BS. it shows verys short-term reaction adn we can't rely on that. in the long run, excessive carbs are the killer. see american diet and obesity there
@@XAE_A_Xii I wasn’t very physically active until I got over my condition. It was the diet rich in “whole food” carbohydrate rich foods like whole grains, sweet potatoes, fruits, and vegetables that actually allowed me to lose the weight and get to a place where I could be quite active. As for the foods you listed as carbohydrate rich, most of them contain just as much if not more calories from fat than carbohydrates. however I should emphasize, the name of the game is not fat vs carbs, but more so Whole Foods vs non Whole Foods. The civilizations that have the longest life expectancies and greatest health quotient eat a diet that is rich in whole food carbohydrate rich foods as well and diabetics who follow in their footsteps massively decrease their need for insulin, and many times even stop it entirely. I know that I could never change any one’s mind with a RU-vid comment so I don’t expect anyone to whole heartedly accept what I say. I just want to point to the scientific consensus and show that “carbs” in and of themselves, are not the problem. It very much depends on the source. I know this felt like an essay trying to show you how wrong you are, but that’s not the intention at all. Just want to bring a broader perspective to another fellow brother/sister on planet earth. Have a great day my friend and God bless! 😊🙏🏼
I did the Keto diet for 7 months. I lost 50 lbs. I thought it was incredible at first! I felt lean and the compliments kept me going. Trouble in paradise started when I had a minor operation. My blood had trouble clotting! I small procedure turned into a very painful hematoma because I was Vitamin K deficient for the past 7 months despite supplementing! I started having chest pains and knew my heart was getting to its limit with all the animal protein and fat. Months of fearing bananas but embracing butter in my coffee was taking its toll. Then I noticed that as I tried to transition off, I would get severe headaches when I ate a more carb heavy diet. I knew I had done something to my body that was not healthy. My body was able to start processing carbs normally after a transition period of a couple months. I am glad I stopped when I did (better sooner). I hope others stop this unhealthy diet and move to a healthier alternative before it’s too late.
I wish more people would accept criticism about keto. Long term, its bad to deprive your body of anything for that long. Sugar, salt even. Most people who don't accept criticism about keto say stuff like "oh well its better than being overweight!" Yeah, sure! You could say that about bulimia too...still doesn't mean the way you're losing weight is healthy for your body. Id like to learn more about how it affects mental health. I've seen countless antidotes online from people with anything from mild depression, to bipolar disorder say they've had their moods improve since they started keto
Jess I will say that I did avoid blood sugar spikes and crashes so I pretty much didn’t have “Hangry” episodes while on Keto. But I found a simple fix when i ate more complex carbs and avoided eating too much at a time. The crash would be much harder if I had a large meal. Just my experience from a “mood” perspective.
@@brocklee2458 I also did the keto diet, even longer than you did. Luckily for me I didn't have any life threatening events. However, I have a lot of damage to heal from. I've been vegan for a little while but I only started a true HCLF diet very recently. At first I was getting heart burn, gas and bloating with everything I ate. Now, since only a few days, I can eat a whole meal of bean and rice burritos with no heart burn, gas or bloating. If feels like a miracle. I'm healing! The weight is stubborn, but it's coming off slowly. I finally feel good enough to start being more active. I was ok before keto, no health complaints. I was maybe at most 15 pounds over weight. After keto I gained 60 pounds, had aches and pains, difficulty breathing, fevers and light headedness. It was awful. During keto, I got taken aside at work one day, and told that a customer complained of my breath. After that I had to go to the office and swish with listerine and they were watching me. Treated me like I was nasty and gross. I'm so glad that chapter in my life is over.
This is now the first video I send to any keto proponent on the internet who claims keto can revert diabetes! Thanks for a funny and entertaining video!
Literally just finishing up my six egg scrambled eggs with mushrooms and about a 1/4lbs. of bacon. and laughing. laughing. I don't need a doctor spouting faux arguments about how this "may" or that "might" be something when reviewing studies and then hawking it as some kind of factual finding. I know it works because I changed my diet and quite literally every aspect of my health improved with bloodwork and diagnostic metrics to prove it.
When u decide to add back carbs after doing keto for a while, there will be a spike in blood sugar.. its jus common sense.. jus like how blood sugar reduces quickly on keto, it may spike up too when sugar gets added.. thats why keto is a lifestyle change , not just a fad diet.. your body learns to regularise hormone insulin so that the next high carb meal gets sorted out as how nature intended it to be.. insulin resistance, high cortisol level, stress, sleep everything has to be in sync for keto or low carb to workout.. give it sometime.. a few hit jackpot in months , others years
Come on, how good is eating a third of Cream on a pint of Cheese with Sour Cream with a slab of Bacon, your Arteries and Heart, are screaming for Help,!! help us please ....
I eat whole food plant based and love Dr Greger, but I would to understand how organisations like American Diabetes association say low carb is OK. Is it all about symptom management?
MegaVegan is right, the standard american diet is so terrible that most people that switch to keto actually change for the better! If keto is making people eat less refined sugars and processed food, then great.
Does the American Diabetes Association say that low carb diets like Atkins or keto are okay? If they do, that shows they are even more corrupt than I even thought. From what I can tell, they are only corrupt to the extent the other disease advocacy groups like the American Cancer Society, American Heart Association, etc. Which is pretty damn corrupt, but pushing Atkins or keto would put the ADA over the top!
Indeed it does. I was Pre-diabetic and given 6 months before going on metformin when my GP suggested keto. 6 years and healthiest I have ever been. Finally, I realised being constantly drowsy DIDN'T HAVE TO BE THE NORM!!!
surprised any GP would recommend Keto lol. Usually they tell you - eat less fat and less sugar. but they forget, it's a receipt for a disaster, such diet will keep you constantly hungry and unhappy. fat food (avocados, not ptocessed s..t) keepsyou satiated foe longer, so you end up eating less calories
After a year of Keto way of eating my primary care physician said on 9-9-19, "You have cured your Diabetes." Type 2 Diabetes. This is after doing full panel blood tests every 3 months.
@@allencrider I do have chocolate cake, without Sugar or Wheat flour. Coconut flour, almond flour, Stevia, and unsweetened cocoa powder. One can have treats without spiking insulin.
@@Auntyalias2014 Why would your insulin spike if your diabetes is cured? Have you taken a glucose tolerance test to scientifically prove that your diabetes is cured?
@@allencrider Insulin spikes when ever you eat anything. That's why Intermittent Fasting is a good thing when combating insulin resistance. Even when you think of eating something sweet insulin spikes. It's a matter of just how much of a spike you want to deal with. As for being "scientifically tested" I've had full blood panel work done every three months for the last year tracking being on Keto. The prior decade I was pre-diabetic and then diabetic before giving up all Sugar, Grain, seed oils, etc. I think before asking me what hoops I've jumped through I'd recommend you do some homework on Keto here on RU-vid.
I don't understand what you are speaking about. I am on Keto for 2 years. i do not just believe my blood sugar level. My mind ability, asthma, body energy are all much better than before. i also eat some rice but not like others. But if the amount of the carb goes too much, my all condition goes bad. So I keep the amount of rice low and no wheat at all. Wheat makea my body muc worse. I lost 44 pounds and I am happy now.
Eric Berg really bugs me. I’m sure he has read a lot about nutrition but he calls himself doctor and everything about his channel indicates that he is a doctor giving advice on how to prevent and treat disease and improve health with food, but he isn’t a doctor. He’s a chiropractor who’s never been to medical school.
oskar tang Yeah they don’t teach enough nutrition, but the conversion of ingested matter into different processes and chemical reactions in the body is insanely complex and we still struggle to understand a lot of it. A medical degree gives you deep knowledge of the body and how it works and a good foundation for understanding nutrition when you study it further. Laying someone on a table and cracking their back won’t do that. You can tell that about Eric Berg. He’s read about a lot of things and has superficial knowledge in subjects, but he doesn’t have that deep understanding of the body. When he tries to go deep he usually gets something wrong .
Amazes me how each person in each camp firmly believes he/she is 110% right and other camp is completely crazy. Reality is there are successes in both camps. Most people can't debate meaningfully.
Both camps insist you lose weight and take you off highly processed foods, so both are better than the standard American diet, I think wfpb will turn out better long term results.
I was told by my dr I needed to go on insulin as I had type 2 diabetes (6 years) I said no and started a low carb diet. Within a month by blood glucose was down to normal levels. After 3 months my HBA1C was below the diabetic threshold. I’m off my statins & off my blood pressure tablets (ramilpil) and lost 3 stones. I recommended a low carb high fat diet. My bloods have also improved HDL up ad Triglycerides down.
@@krism6260 I am 7 months in from an A1C 13.1, with numbness on one foot. Pain in my chest when my sugar would spike to 400+ at certain times. I could tell the location of my kidneys most mornings because they hurt. I have been a diabetic for 15 years. I was a strict vegetarian for the last 3 years. It got my 14.7 A1C down to 13.1 with medication but my condition like every diabetic progressed. I was not on the eat more fat camp. I am from the era of that “Stop the insanity”. I believe everything that woman said and if there was fat in it, I did not want it. So keto and low carb high fat was not something I jumped in with open arms. But I was tired of being sick cause I started getting infections, UTI, tooth infections, yeast infections and all I got was a prescription of antibiotics. When I wanted to do keto the doctor was against it, he did not want to work with me with adjusting my insulin while on keto. He was willing to drop me. I took my health into my hand and stop my meds and went full keto. I measure my blood sugar before a meal, a half-hour later, and an hour after. Sometimes I would do it again 2 hours after. It took me three weeks to see a fasting blood sugar in 120 and another week to see it in the ’90s to 100. 3 months later I went from an A1C of 13.1 to 6.1 no meds. The nurse couldn't believe it. Three months after that my A1C is at 5.2. You don't know how sick you were until you are healthy. I lost 50lbs, I don't need a constant supply of coffee, to function. I sleep like a baby. No more pain in my chest, the numbness on foot is about 90 percent gone. My skin tags have disappeared at 55 my energy is that of when I was in my 20s. No more infections so far. I had UTIs that did not want to go away. To answer your question. No I did not the gtt, yet. But do you think that after living in misery that if I don't see the results I want, I'm simply going to say this doesn't work? The way I see it you can have a peanut, egg, mango allergy. My body is allergic to certain carbs.
@@krism6260 I have met diabetics that have been 5 and 7 years low carb or keto and they are healthy and loving life. Everyone has to do what worked for them. We have to learn to accept that what works for one person does not work for the other and that ok.
Thank you so much for making this video. People really need to know this! I get genuinely scared for people's health when they try to follow a keto diet because of all the studies that say that it is bad. Please people don't do it until you have done true research.
What about the studies that say its good? You can't flat out sit there and say a diet is good OR bad and assume it'll apply for everyone, and especially refer to studies when in reality, most people don't understand them and/or aren't going to pay to read the full study, and will just read the abstract. I'm not a keto freak, I've been following from afar for a few years now because ill get extremely bad stomach cramps when eating certain things and wanted to narrow it down (I wasn't paying attention to what I'd eat at all)... I just think its wrong to say its completely unhealthy and assume people will come to that conclusion just from "research". "Do your research" is what anti vaxxer nut jobs throw around thinking they know more than educated professionals and doctors.
@@orangeradishneo You are right that there are some studies that say that it is good in specific cases, or that it's not harmful for certain things. Such as a study that looked at endurance athletes and found that being on the keto diet did not actually impair their performance, however, the standard meat, cheese and butter keto diet is not healthy. Many studies are showing that saturated fat causes multiple health issues and that animal products cause health issues too. I have a whole video on heart disease and why eating meat, regardless of the fat content, maybe causing heart disease. If a person eats a diet high in animals foods keto or otherwise those health issues can and will occur.
@@orangeradishneo most of the studies I have seen where a ketogenic diet does appear to be beneficial are only referencing it's use in treating epilepsy, something that doesn't apply to the broader public.
Greger is simply wrong here. Ketogenic diets, in clinical trials, imorove insulin resistance. Greger is using a temporary response to glucose to extrapolate out to IR. When IR is studied directly, it improves after a low carb diet.
@@B.H.1987 Yes. I realised that Greger was producing promo videos in his 'fish and diabetes' video. Pulls up titles of Six meta-analyses (which concluded no association) , and Greger pulls *one study* out of *one meta-analysis* and flashes up the content. That's not how you convey the accurate state of science to your viewers.
I had prediabetes 6 years ago, I went to keto state accidentally because it turns out that I am allergic to fruits and plant based foods. 2 years ago I cheated and experimented by eating 14 big bananas in one meal and guess what? After 4 hour later I tested blood sugars and it was 90 which it tells me that my prediabetes was gone, but i regretted later because I knew that I'm allergic to fruits. Oh and my triglycerides used to be too way high and now they are in the normal level.
The fallacy in this video (series) is the assumption that a high carb diet is “normal “. What if the default human diet is high fat? In that case it would be non-sensical to expect “cured” T2 diabetics to ever quit the keto diet.
What? For most of hominim history we were not hunters nor effective scavengers of animal fats. This is why a high fat diet causes disease long-term but a high fiber, plant-based diet is disease-preventing and curative. Are you joking?
tamcon72 Do you have a source for your assertion about our history as a species? Cave paintings are a hoax by the meat industry, I guess, as are 200.000+ years old tools for cutting meat. Lol.
@@MikeEnRegalia Hominims didn't originate in the Paleolithic era--their anatomy and biology was already determined--and to base your ideas about our diet on this is "cherry picking," and that you must accept cherry picking by Neolithic era fanbois and gurls, likewise. Which means endless arguments about how civilization is beneficial and we are supposed to eat farmed grains, pulses, vegetables, and fruits, which I'm sure would not like. No one is denying that stone and other tools in the fossil record indicates a practice of animal butchering. You people assert that this was common and regular and that animals were the common, regular, and _preferred_ food source for early Man, for which there is no evidence. As I have explained to another usernames issuing exactly the same talking points as you--are you all getting instructions from a central location? The Max Planck Institute? Shawn "I barely passed the medical boards" Baker?--there is abundant new evidence of the more comprehensive diet eaten even in early Paleolithic times. Because plant foods biodegrade more readily than animal skeletons, and require less processing to consume, the evidence for their consumption has been obscured until recently. We are not carnivores biologically and neither were our antecedents--we developed the ability to manufacture enzymes necessary to digest primary animal protein fairly late in our evolution--and we would have gone extinct long ago if eating a biologically inappropriate diet. "Cave paintings, tho' " The reason Paleolithic cave dwellers painted those hunting scenes was as a totemic ritual action taken to achieve successful hunts, presumably because hunting was very difficult and frequently unsuccessful; they would not have had to do "affirmations" otherwise. It took a very long time for the large mammals encountered by humans to be driven to extinction, and humans weren't solely responsible. This is the consensus among actual paleontologists, anthropologists, and archeologists, though they demur that it is the best hypothesis until more is learned, as further discoveries arise. I am not providing you with evidence of what the rest of us learned in college, and which anyone holding forth on this subject should already know.
tamcon72 our digestive system is adapted to a meat-based (omnivorous) diet. You’re welcome to write another couple of thousand words in response, containing a multitude of fallacies and factual errors. I am muting you, so good-bye and good luck.
@@MikeEnRegalia I know you didn't read what I wrote, or didn't comprehend it. I was super specific to prevent further dispute from someone lacking my knowledge base and too lazy/biased to rise to it. Mutual bye.
Idk.. I do healthy Keto.. never felt better... lost tons of body fat... my insulin levels are healthy.. my cholesterols and triglycerides are optimal...
@@AdventureElliot Did you watch the video at all? Intramyocellular lipids (fats) in the cell's insulin receptors cause insulin resistance, not carbs. A high sugar level in your blood is a symptom of diabetes, not the cause. Introducing more fats and no carbs isn't fixing the problem, it's just delaying it and making it worse as your cells insulin receptors get clogged up by this high fat diet.
Special thanks to you(r team) and especially your German translator Markus Tschögl! I need to show this to my mother in law asap! She might finally be motivated to make a change drastic enough to change her health drastically :)
I know it’s your MIL, so you have your motivations, but unless she’s extremely naive and stupid, she’s not going to go back to the horrible SAD diet. So, good luck getting her diabetes to come back, by actually listening to the quack in this video.
If methylglyoxal were such a problem, are you saying the Eskimos are on the brink of death using that logic? You also highlight a bunch of articles and use correlation instead of causation to push your points.
The ketogenic diet worsening diabetes makes sense if it involves being on a high fat diet and reversing diabetes involves clearing fat or intramyocellular lipids out of the cells. Too much fat getting in the way of insulin working properly. Now let's examine why in this video.
More scietific sleight of hand by Greger, and his followers lap it up. Why not use actual studies on Keto diets and insulin resistance? Because they don't show the results he wants.
I’m a newbie to Keto which frankly hasn’t worked for me yet as I lost weight that I didn’t need to lose but was never in ketosis. I have been intermittent fasting for a few months now. Recent bloodwork shows pre-diabetic, A1C borderline and high LDLs. I’m an avid runner and BMI is 18.5. So confused on what to do next…
Well, for starters, you’re in the right place. Dr. Greger’s videos are an excellent resource if you’re looking to find ways to eat healthier. In that regard, the most important rule to remember is to simply eat more unprocessed plant foods and less animal foods - meat, dairy and eggs. All plant-based “reversal diets” preach that one tenet - Pritikin, Ornish and Esselstyn. If you’re willing to give any of those 3 diets a try, that will help you to get your numbers back on track. All of them are quite restrictive, but that’s also why they work wonders if followed closely. Pritikin’s will at least allow you 1 serving of meat per day. If you’ve got the will to go full vegetarian or vegan - talking Ornish or Esselstyn - be sure to take some quality Vit. B12 and omega-3 fatty acid supplements. If you’re not sure you can handle any of those diets, all is not lost. Just start reading all you can about how to eat a Mediterranean diet. That will get you eating healthy in general without having to cut out a ton of animal protein. And, if you haven’t already, be sure to check out Dr. Greger’s website. There you can use the search function to look up tons of different foods and health conditions - like diabetes’ link to saturated fat intake. Best of luck!
Ignore the poster above, and instead read Dr. Phinney and Dr. Volek’s two books, one on The Science of Low Carb Living and the other Endurance (the Science of Low Carbohydrate for Performance), which shows their groundbreaking research on keto for regular life and endurance athletes (runners such as yourself) .
It literally doesnt. There are multiple studies that look directly at this issue. Greger doesn't use them, but chooses to show a completely different phenomenon. Its scientific sleight of hand, and his audience laps it up
Keto is really bad for even more health areas. For me, it destroyed my heart arrhythmia. After a few years now on a plant based diet with low fat, the heart got back to normal.
The people that are saying that keto diet has cured their diabetes is like someone saying they used to get anxiety when talking to girls but now they don't get anxiety because they completely stopped talking to girls.
We have followed broken diet advice for generations, I believe we can afford to give keto a try before rejecting it outright. There are really too much factors at play to say anything so definitely and at a risk of being biased.
Dr Greger, can you please distinguish between omnivore keto and whole food vegan keto. In your earlier writings you've suggested vegan keto might be beneficial or safe. Yet many whole food vegan options are high in saturated fat, beyond just coconut and palm. I'm under the impression, not just a low saturated fat vegan diet is more health promoting, but a low fat diet in general, with the exception of adequate omega 3 intake, in terms of optimal cholesterol, heart and vascular health. If you could please discuss in detail, the optimal choices for overall fat and saturated fat intake, for those already adhering to a diverse whole food vegan diet, this would be so helpful.
@@happygimp0 If I'm not mistaken, the original Ketogenic diet was 100% macadamia nuts. Brazil nuts and pine nuts are similar ratios... not that anyone should consume a significant quantity of Brazil nuts, as this could lead to selenium poisoning.
Sorry, but I have been high fat low carb for 3 years, all my biomarkers are better. And never felt better in my 61 years of life. For me, and the 100 of thousands of others, it corrected blood sugar. For me, you’re wrong.
Congrats on making your life better. Yeah this series on "keto" (I put that in quotes because half of the studies he relies on in his smear campaign are not even keto, they are atkins) is nothing more than a smear campaign. If all markers are looking much better and continue to look good, I'd say carry on :).
i have been waiting for this video for 2 years. finally . i must applaud the channel red pill vegan who has been raising awareness consistently. the nhs has rolled ahead low carb diabetes programmes literally training gps in prescribing low carb to diabetics and a gp called david unwin who takes the keto approach and calls himself the ‘low carb gp ‘ has won awards . more awareness of the reality of this fake ‘reversal’ of t2d is urgently needed in the uk
There are some really important key factors that are completely misrepresented in this argument (and these studies). Carb reactivity does get worse after going on a keto diet. There is an "adaptation period", both for adopting a high-fat diet and for reintroducing carbs. None of these studies seem to account for this adaptation period, immediately assuming that the carb reactivity during the adaptation period is a sign that keto is making things worse. I think the keto diet is extreme, but I personally have experienced great results. I used it as a tool to reduce my carb reactivity. Potatoes used to knock me out, any sort of bread would make me exhausted. I can eat carbs and react much less to them. But at first, when I was re-adapting to carbs it was a lot worse. I certainly am not the first with this experience. I generally prefer to follow the science, but given that studies are conducted by humans with biases, there will always be flaws in the methodology. In fact, I've seen equally as many papers that suggest that its a better way of eating as those that suggest that it'll make things worse. It is easy to cherry-pick. I now eat something that resembles more of a mediterranean diet. Societies that eat a mediterranean diet historically have had people who lived the longest. These diets had a moderately high level of fat, as well (think olive oil).
Mediterranean diet is successful because it's good carbs and good fat mainly, with no processed crap. So you eat high quality cheese once in a while, fish in moderation, extra virgin olive oil but no other processed fats, little meat and a lot of beans, whole grains, seeds, vegetables and some fruit. I personally think that it is indeed the best way to eat but as I can't support fishing due to overfishing happening in all countries and can't support dairy industry because of its abuse of female reproductive system and horrendous environmental impact, I've replaced them with Japanese food (sushi or ramen with algae and pickled vegetables) and nuts (often in a form of cheese like products) respectively.
@@GregVidua I agree with your analysis of why the Mediterranean diet is successful. But I still return every once in a while to a low-carb diet. I think it is a mistake to think that nothing can be learned from the proponents of a low carb diet, in fact, a lot of what I've been reading suggests that the body is meant to do both. Go through periods of time in a slightly-ketogenic state (due to food/crops being out of season with hunting/fishing being the main staple) and then when food is in season, return to eating a moderate amount of grains and legumes which raises insulin, signaling to the body to store some of the energy in form of fat. This would be similar to the regular feeding pattern of most omnivorous mammals as well.
@@simonhawkenson675 what are you talking about? Grains and legumes are harvested right now (end of summer, beginning Fall) and stored for fall, winter, early spring. Most peasants in Europe had No right to hunt. They would have been persecuted as poachers. They relied on one or two pigs that were slaughtered in late fall for optimal storage. That meat was consumed in small portions as an addition to grains and legumes. It was not a substitute and only on some high holidays became a roast the main course of the meal.
@@ludicrousone8706 I wasn't referring to the peasants (or any one group of people), aside from those who eat a Mediterranean diet. It would be stupid to say that we should model our diet off of what the poor peasants ate. Because they certainly ate terribly. That being said, some of them were definitely in a ketogenic state for a while, because they were starving. There was a whole French revolution over this. "Let them eat cake"
@@simonhawkenson675 I responded to your argument that the Winter ist traditionally reserved for fishing and hunting. And this ist simply not true. Peasants in Europe found themselves often starving, for fall failed crops, failed enforced Management and exploitive taxation. The French Revolution was just more successfull then all the other rebellions driven by food shortage
dj121 fat is essential.. ever heard of essential fatty acids?? Our cells need them, just like they need essential amino acids. Is there such thing as essential carbs?? Nope!
@@AdventureElliot Yes, carbs are essential! Not essential to stay alive, but essential to be healthy! There is also no essential saturated fat or animal fat. Leafy greens and fruits alone can give you all the essential fatty acids
dj121 ketones are necessary and preferred energy source evolutionarily speaking. We didn’t have an abundance of fruits and vegetables in the higher latitudes. We had animal products and our own bodyfat that we relied on from the growing season.
I am not persuaded by the argument here... On the other hand, Robert Lustig's argument about the culpability of sugar, particularly fructose, in metabolic syndrome (including diabetes) is thoroughly convincing, Greger argues that if people on a low carb diet start to consume carbs they get a massive insulin spike because they are not carb-adapted. But that is like saying that if a non-alcoholic has a couple of drinks it will have a much larger effect than on an alcoholic who has a couple of drinks. Carb adaptation is not necessarily a good thing...
@@joaogomes850 - what about saturated fat??? What does that have to do with anything! Diabetes is caused by GLUCOSE and not fat. Do you understand that the body stores glucose AS FAT?????? Do you understand that dietary fat is digested? We are not an empty bag that people throw things inside one's mouth and all the food just floats in our blood the same way they came in. They are digested and broken down. So the fat you eat will be processed and used for many things, whereas the carbohydrates you eat will be broken down and used for energy ONLY and if you fail to use it, the body will store it, as FAT.
@@montycorawe have known for over a hundred years that diabetes is caused by intramyocellular lipids aka fat. You are just demonstrably wrong. Fat inhibits the functioning of insulin. So then when you eat carbs & fat (or are fat) your body can’t process the carbohydrates and your blood sugar rises. Don’t take my word for it, look it up.
Could the high reaction to sugar after being on low carbohydrate diet be temporary? Is the keto mania because it helps to reverse the effects from going the opposite direction before? Can keto be an effective reset, followed by moderation in carbs. No one can deny that a low sugar diet is a lifetime goal. For me, keto is good for now. It’s applied effectively for my health concerns NOW, maybe not for a lifetime. Lots of people review supplements negatively because they never needed them in the first place, or they have an inherent problem that makes them react to the product. Others do wonderfully, for a time. Everyone is different at different times. Also, there’s troubling lack of completeness to the analyzed data here. It’s very specific, yet not specific. The whole picture needs to be looked at. Was the meat cooked healthily? Was it quality meat? Did they separate out the natural sugar from the processed sugar? Did they mix carbs and fats? Also, sometimes you’re forced to chose the lesser of two evils.Bariatric surgery or temporary keto diet. Obesity can come from not just over indulgence, but the root can a multitude of things outside of a persons control. Notice he always says things “can” or “may” be such and such. Very safe indeed. The proof is in the application to your own situation, making adjustments and making educated choices. The education is not helped with “Mays” or “Cans”.
I have T1 diabetes and eat about 400-450 gm of carbohydrates per day and use about 31 units of insulin and with an HBA1c about 6.3. I also have greater resistance to the host of diabetic side effects caused by hyperglycemia (which certainly I still have) by elevating my antioxidant levels rather dramatically. I first heard about the Atkins/keto diet just a few years after developing diabetes at age 21. Many diabetics find they have the condition by going into diabetic ketoacidosis. It occured to me that inducing the state that, were I to stop taking insulin, would kill me I would have to be considered suicidal.
@@stewartedgington8164 - Of course! Ketoacidosis is a medical condition in which your ketone level is above 14 mmol/l - It happens as a complication of diabetes, it is involuntary and it makes your body turns really acidic and that is why it is very dangerous. Ketosis is when you purposefully decide to cut carbohydrates from your diet, or if you fast for more than a day, then you will reach ketosis, which means your body will burn fat as fuel and no longer glucose. When you are in nutritional ketosis, the max you are gonna reach is 7mmol and that is pretty rare and hard, most people will stay at around 0.5 to 4 mmol. It is hard to keep your ketones as high as 7, and not really necessary, unless you have epilepsy or other neurological conditions that are treated with the ketogenic diet, but for weight and blood glucose maintenance, 1mmol is already great, for neurological, more than 3mmol is required.
I still think that a debate would be more interesting than this series. I have the feeling that dr greger and his staff are picking studies that most fit their view point rather than being open about the keto diet
debate ? on what ? you mean evidences should be debated upon ? Aren't they enough on their own? We have mountains of evidence that saturated fat is bad. What needs to be debated here ?
Well, all lf these videos are ok, nothing bad about them, but it would be nice to see a defense of the keto diet, you know, just to see what the other side may say. I personally find it funny that the atkins diet is even mentioned in these videos, for example, and often what is called low carb in these studies is actually high protein, not keto at all.
"I have the feeling . . . " This is your bias talking. There is a paucity of hard data on ketogenic diets long-term. There is no equivalent with all the data on other diets from which to make comparison.
I would also like some dialogue. The keto guys will claim that everything is cherry picked anyways. But without Dr Greger or someone qualified being able to respond directly many people will still not be sure what to believe.
You have a video where you define the ketogenic diet you are speaking of ? You keep on mentioning Atkins, Atkins is similar but not the same. Responsible ketogenic diet educators always emphasize the importance of vegetables and moderate protein. Pls look up Dr Fung and Dr. Westerman’s work one is a nephrologist and one heads obesity clinic at duke university for past 20 years.
5:25 I found this part with a significant higher complexity. Please like if you would like Greger to go deeper into this topic for us 'debaters' to have a better informed stronger arguments.
The problem is this simply isnt true. Greger is confounding temporary phenomenon with the underlying pathology. 'fasting' for a week results in exactly the same temporary response to glucose. The question is what happens to *actual insulin resistance* on a low carb diet or fasting? It improves. Greger doesnt address this. A recent study by the US military found that after a three month Ketogenic diet *Insulin resistance was improved by 48%* compared to controls. This is repeated in multiple study findings I wonder why Dr Greger doesnt mention these, but merely mentions the results if an immediate glucose test?
So indeed there is a form of insulin resistance when taking in a high carb meal while having been on a ketogenic diet, but this 'physiological' insulin resistance then disappears after a few days of higher carb intake. Would that statement be correct? By the way, is it not also important to see blood levels of insulin. A resistance would mean that insulin is present but not doing its job effectively, but what if there is just an inadequate response to the glucose intake? I think it would also be interesting to see the opposite tested. The response of a keto dieter and a (high carb/'normal'diet) control taking in a high fat meal. Then test for things like triglycerides and whatnot.
@@sam11443 this is an excellent response. Yes. There is a temporary 'insulin resistance-type response' but it's not pathological, I.e it reverses itself within days. That's not pathological insulin resistance. The triglycerides comment is interesting. It's not just fat that causes high triglycerides - lots of simple carbs and fructose can push high trigs in the blood. It's not uncommon to see people that are really happy with their low ldl, and who fail to recognise their very high triglycerides (which are also fats in the blood) and their very low hdl. Fully raw Kristina and Dr Garth bloodtest is a great example of this. A high trigs/hdl ratio is a reasonable proxy for insulin resistance. Over 2-3 is worth investigating for IR and metabolic disorder. The other high risk factor for IR is high visceral fat. Weird for keto to reduce visceral fat, lower trigs, raise hdl and (supposedly according to Dr Greger) cause Insulin resistance.
Except it's a short-term study--3 months with 15 people on keto, and of course insulin resistance improves some when you lose weight. But if you can't do well on a blood glucose test when eating carbs, you still have one of the defining features of diabetes. Also, the long-term effects of keto--as shown in studies of kids with epilepsy--are very alarming.
@@karlwheatley1244 Greger is (intentionally) confusing two different phenomenon. Hepatic (or pathological) insulin resistance with temporary glucose sparing. The affect he is discussing is known as the 'second meal effect' and it disappears after a second meal (or third meal). Does anyone really want to claim that insulin resistance can be cured after two meals. That's absurd. Your body has downregulated glucose metabolism and up-regulated Lipid metabolism, so isn't prepared for a glucose bolus. Again, this is a transient effect and has *zero* to do with the pathological state. It's a silly and trite example, but it's the equivalent of suggesting that being in a dark room for an hour will lead to blindness.... because it reduces your ability to deal with bright lights when you immediately encounter them. AFAIK, weightloss, specifically visceral fat loss is the only mechanism shown to improve insulin sensitivity. If you have studies to the contrary, I'd love to see them.
@@scrapbus9681 Thanks for your reply. "Again, this is a transient effect and has zero to do with the pathological state." Links? Also, the methyglyoxal production found in studies cited in the video is itself a pathological effect, as are the long-term effects of keto diets found in kids with epilepsy or the higher mortality found in people eating garden variety low-carb diets. "AFAIK, weightloss, specifically visceral fat loss is the only mechanism shown to improve insulin sensitivity." Insulin sensitivity improves dramatically when eating diets with very high carb to fat ratios and when intramyocullular lipids are reduced, both of which happen on very low fat whole food plant-based diets. Regarding the latter, for example, see www.ncbi.nlm.nih.gov/pmc/articles/PMC4762133/
Your presentation is very misleading: I have T2D and following a LCHF diet helped me reduce my HBa1c from 8.2 to 6.2 in 4 months, my TG from 108 mg/dl to 91, my Ch-T from 140 mg/dl to 124, my CH-LDL from 0.74 mg/dl to 0.47 , increased my CH-HDL from 0.50 to 0.59. The bonus: I lost 11 kgs (from 74 to 63). I haven't taken any form of medication. Note: if an individual is on a LCHF diet, it is very normal that they have blood glucose spikes after a high carb meal, that is known as the second meal effect. The second meal phenomenon is due to fact that the metabolism has re-adapted itself to fat (healthy fats) ingestion while on a LCHF which necessitates more bile and less insulin. The same phenomenon would happen to an individual on a high carb diet having fatty meals (not enough bile to help digest). I feel more comfortable with high bile than insulin , would you? By the way, thanks to regular exercise (walking for not less than an hour daily) I noticed an increase in my body lean mass and less fatigue, contrary to what you have quoted and presented as fact. Actually, it is fiction, my case is fact. P.S. my sexual performance? My wife is so happy: rigid and sustained erection ...
@@RiDankulous Thanks for sharing your personal experience about metabolic syndrome. In fact, I went on a low carb diet since Jan. 2019; I was diagnosed with T2D (HBa1c = 8.2). You can check my labs in my first comment, my blood pressure was OK, 120/80, and my lipid profile wasn't that bad. I refused to take any medication and did lots of research basically on RU-vid. I went low carb with much reliance on veggies; I had lots of problems: flatulence, constipation...Two or three months into the new health program, I "converted" to LCHF and things took a very promising turn. My last score in blood glucose is 5.8 (September 2019). I lost around 11 kgs in less than 6 months (from 74 to 63) my BMI is stable and I am on a weight maintenance diet. My blood pressure is generally around 100/60 and my heart beat is 67, at rest. I am 55 years old. I did all this by my own and lots of RU-vid research. I am no authority to prove that LCHF is the best diet scientifically; but I am a case study, it worked with me and I had very laudable results. I didn't do any IF or Keto, just a form of LCHF. Still, I have to confess that I laid much focus on avoiding processed food and refined carbs. Absolutely no sugar except for what is available in fruit (basically with lunch) and other macro-nutrients with lots of attention to low-index and green leafy veggies. I have been on a diet low in glucose and a reasonable ratio of healthy fats (animal sourced: butter, tallow, olive oil, cheese...). I take around 3 table spoon of ground flax seed (home-made) daily; I give much care to macro-nutrients rich in Omega-3 to help improve their ration with Omega-6. Besides all of this and other things I walk for no less than 90 min daily and have good quality sleep. I did a personal log where I keep track of all my bio-data (labs, blood pressure, BMI, the food I ingest....) I heartily congratulate you on your good results and wish you life-long excellent health. My motto is "Reach death-time with a healthy body"; longevity doesn't mean much to me, good health does.
@@RiDankulous What I didn't appreciate is the zealot way the presentation took: Dr Greger was referring to LCHF without specifying the type of diet. LCHF comprises a good number of diets and Greger seemed to be cherry picking data and sometimes distorting them to suit his approach. I was following his channel and other channels, this gave a me priceless opportunity to compare points of view. You can check the channel "LOW CARB DOWN UNDER", for example. Here are some links: ru-vid.com/show-UCcTTiHZtNpiqD2EubIO5HFw - ru-vid.com/show-UCPn4FsiQP15nudug9FDhluA
Good work Doc! I was intrigued by keto, but like the robot in Lost in Space, I kept getting background thoughts of "warning, warning!" It just didn't make sense. Your recent series about keto is exactly what I needed. This particular vid was a home run. I eat mostly vegan, but do skip when my gal comes around... one thing I noticed is that meat has a similar "sweet" flavor as refined carbs... and that got me thinking about the diabetics I know, who all eat a combo of meats and sweets... then rethink about the diabetes and eat more meat... which as you mention in this vid, makes future carbs even more toxic... fascinating. Thank you.
Well, I followed the 'links to scientific resources' and it leads to the same list of videos by the channel owner. Tried to look at channel owner's credentials apart from the letters he puts behind his name and found no description of his training, medical specialty or science based training. This would seem like another hach channel pretending to be speaking for science. Touting evidence based philosophy while not providing evidence. The concepts behind this video are completely off base.
@@user-fy7ri8gu8l Thank you for providing the sources. I honestly looked on the link in video description and it just took me to a page that showed links to the other videos in the series. I did look up all the 2012 + articles in the citation list you provided. The most recent articles provide evidence in favor of a ketogenic diet. In particular Hussain et al. (2012) shows better outcomes of the ketogenic diet for patients with type II diabetes than calorie restriction. Hallberg et al's (2018) study is the same. All the blood assays show very strong response to a ketogenic diet and improved outcomes. Both these studies have decent sample sizes +300 patients with good control populations on which to compare research outcomes, The video rests much of its thesis on the results of Perry et al. 2017. That study shows that binging on a high fat food generates negative impacts on glucose sensitivity. The methods of this paper are limited - only 15 participants - all of whom are healthy and do not have type II diabetes. However, if the paper is read critically there is also a major flaw in how this video interprets the Perry et al study. Simply click on their Table 1 data to see the composition of the so called "high fat: diet fed to patients as the treatment. Indeed, it has a lot of fat (440 g worth and nearly 6000 cal). It also had an incredible amount of carbs - 192 g. That is 4 x the daily carb allowance of a low carb diet and 8 x the allowance of a keto genic diet. Obviously the outcome of the study could be just as readily (and mechanistically more likely) ascribed to the massive carb intake with the treatment as it could to the fat in the diet. So the thesis espoused in this video has problems. Regarding the esteemed MD and star of the show. I did a search on Scopus to find some papers he might of have published. Indeed, his name came up blank on any research related to medicine or nutritional research apart from his online content. This isn't to say he cannot interpret peer review papers, but he is certainly not participating in the creation of science.
@@RiDankulous Joe I've had similar results on a low carb diet. Off the BP meds, lost weight, stronger athletic performance in endurance sports. I'm sure if we sat over a coffee and talked we'd find a lot of commonalities in our approaches to diet that might be lost in the keto vs vegan youtube wars. Among those commonalities: focus on whole foods, keep daily calories within a range that is right for you and your activity, keep a diversity of diet items, consider micro as well as macro nutrients, find a sustainable meal plan that you can stick to. My reaction to the video was really to do with citing a paper that was a very poor representation of keto and its implications. The paper in question was a classic case of misrepresentation. The paper was in reference to the effect of a binge meal on glucose sensitivity. The authors used 'high fat' to describe their binge meal, but it was really high carb, high fat, high calorie meal that was provided. The paper was cited as evidence of why a high fat meal leads to glucose insensitivity. Everyone agrees that putting refined carbs with high fat is bad. The issue is conflating a high fat + refined carb meal with a low carb/high fat alternative endorsed by keto.
Correct. Greger uses studies on a temporary response to glucose, which is irrelevant. The question is what happens to *insulin resistance* after a ketogenic diet? A recentnt *US military clinical trial* found a *48% Improvment* in insulin resistance after a 3 month Ketogenic diet. That's massive, and in line with other studies I wonder why Greger doesn't use these direct studies, but chooses to use oblique ways of 'proving' his thesis?
I'm supposed to avoid glycotoxins by eating more glucose, and go through at least one hour of nerve damage due to high blood glucose levels while waiting for the insulin to finally kick in, so I can control my diabetes? AGE's are mainly formed in cooked meats and high carb meals. Why can't I avoid both? Were this keto dieters using animal fats or vegetable fats? I know for a fact animal fats increase insulin resistance and make my diabetes worse, but I haven't experienced the same with plant sources of fat (raw, not roasted or with added sugars, because those add glycotoxins too).
You can see a large sampling of AGEs here: www.ncbi.nlm.nih.gov/pmc/articles/PMC3704564/ Bacon is one of the worst! But if you compare tofu, broiled versus boiled, the effects are dramatic. Dr. Greger talks about AGEs more here: nutritionfacts.org/2017/10/24/foods-to-avoid-to-help-prevent-diabetes/ and here: nutritionfacts.org/topics/advanced-glycation-end-products/
@@SittingKittyColorado I knew this, and if you look at the seeds, raw, they are way less toxic than any of the carbs, oils or meats. That's why I don't agree on how he exposes this. Not all fats have the same effect, and high carb doesn't work for everybody. If I do High carb, even WFPB, my glucose levels go nuts, I can't exercise, sleep quality is decreased, I feel without energy all day, get my vision blurried (retinopathy), get kidney stones, nerves start to hurt, get fat, and hypertension kicks in. Excess insulin creates too many complications, can lead to cancer and decrease lifespan.
@@mora2k -- Sounds like a job for TrueNorth Health in California with Dr. Goldhammer. You need someone to reset your immune system and your gut and then get on track. But that's just my opinion. www.healthpromoting.com/
Nice video! It feels like people want some of the benefits of fasting (ketosis), without actually having to fast, and thus the fast-mimicking "keto diet" fad was born. But if you really want to go into ketosis in a healthy way, then just practice fasting, which has only positive side-effects and none of the negative side-effects that the "keto diet" has.
I lost 90 lb on a keto diet which was called an Atkins diet back when I did it and immediately after doing this diet I was diagnosed with type 1 diabetes now I've gone completely plant-based and my insulin levels have decreased while I eat more carbs proving exactly what Dr Gregor was saying
i also have type1 diabetes, and my insulin sensitivity did not change a bit since i went high fat low carb diet. 1:10 insulin to carb ratio, which is higher than average, with multiple years of t1d.
You mean atkins series right? That's what I fair amount of the studies he highlights in the videos are about. There's quite a difference between keto and atkins
This is misleading. I agree that keto makes you more intolerant to carbs because of the increased fat intake, but on the other side of the spectrum, a high carb low fat fat makes you just as intolerant to fat. So why not eat a HCLF diet? High carb low fat diets cannot be healthy because they require you to lower a macronutrient (fat) that is crucial for good health
Reverend Al sure. It’s called intromycelullar insulin resistance. The more fat you eat, it gums up the cells making it hard for your body to uptake carbs. This is the reason why all major WFPB doctors recommend a diet that’s more or less “low fat” at 10% or so of calories. When you start upping the fat, the combination of fat and carbs don’t work well, which is why the SAD diet is a recipe for disaster. The same mechanism applies to low carb keto diets; if fat intake is high, then it follows that carbs must be heavily limited. It’s how the body works
Reverend Al I used to believe high carb diets and low carb diets were both different ways to “skin a cat.” Disease reversal happens in both diets. The caveat is that low fat diets require you to lower an essentially macronutrient (fat), which without it, is impossible for the body to be healthy
You’re full of it. Glucose intolerance is quickly reversible if need be (in 1 week) on a ketogenic diet. This has little to do insulin resistance, which takes months or years to reverse, and more to do with your body becoming more adapted to using ketones for energy instead of glucose. You can observe analogous things happening when you first start doing keto, except everything then has to do with your body's unadaptive utilization of ketones and fatty acids.
Spends more time on analogies than facts...2 days on keto, 1 week on keto, few weeks on atkins (not keto btw)....it takes longer than that to get into ketosis. Lots of flowery talk, little facts and no long term study results.
From London Brixton UK. The best bit about the keto diet is making almond low carb bread recipe & no rice or pasta. I am a black Caribbean woman, n we love 🍞. But I want a tiny slim waist. So this is the only bit of keto that works for me. I am vegan.
When you get pats of information and don't relate... I fixed my carbs intolerance not only whith the keto diet and fasting but also recovering the good bacteria on my gut! Yeah, now I can do all those thinks and also eat ice cream whitout any blood spike. Thank you ketogenic diet!
I had suspected this for some time. (If it sounds to good to be true....) I am very interested in what you might have to say about fasting and Diabetes. Thanks for all the hard work you and your team do for us!
@@ashleytaylor994 it does. It reversed my pre diabetes then my husband died and I ate like crazy, was diagnosed type 2. Now I’m back to one meal a day and have normal blood sugars every day. If it weren’t for Dr Fung, I’d still be listening to advice to “eat 6 small meals per day to avoid type 2”. Honestly wonder if food and medicine are sending this message for profit. What’s more, I’m 58 and don’t have any joint pain now!
@@aliciaali8299 Yes, but the long-term health problems caused by being on keto long-term should warn professional organizations from recommending it for anyone unless they were already suffering from something like frequent seizures--something that might make the health trade-offs worthwhile
@@karlwheatley1244 Average diabetic already loosing 10 years from high blood sugars, thats not good enough trade-off in your opinion to justify low carb diet?
@@magyararon6918 Thanks for your reply. "Average diabetic already loosing 10 years from high blood sugars, thats not good enough trade-off in your opinion to justify low carb diet?" Low-carb diets don't inherently reduce all-cause mortality, and you can cure diabetes on diets high in carbs too, so NO, that doesn't justify them. The key is to eat mostly whole plants foods with lots of fiber, and that discourages overeating (and thus diabetes), and promotes the best overall long-term health outcomes. If people DO go low-carb, they should eat mostly plant protein, mostly plant/unsaturated fats, and the few carbs they eat should be high-quality carbs--that combination lowers mortality compared to the average western diet. However, if people go low carb and eat lots of saturated animal fat, animal protein, and low-quality carbs, that increases mortality over and above the already-dismal mortality rates for western diets. Having studied the issue for more than a decade, low-carb gurus simply can't be trusted to tell you the whole truth. Take care.
That reaction on sugar after high fat diet is maybe because you are just fat adapted? Probably turns around after a few days, so that graph doesn’t say anything. Give more data please before making jokes for the rest of the video
I had to do a ton of research on this for one of my nutrition courses. There are dozens of studies that back this up. I would post links, but many of them are pay to read.
@@heartdragon2386 Use SciHub to access paid research for free. Simply enter studies name or pmid or doi into their search bar. Dr. G's got a vid on it.
Coe Hart one of the evidence against Keto that there is no long study on it. But still there is studies that against it? Send the links and don’t worry.
In terms of insulin sensitivity, yes. He actually presented a study showing the improvement in insulin sensitivity even without weightloss on a high carb high fiber diet (not necessarily vegan).
Check out Dr Barnard's diabetic program or Mastering Diabetes, both on FB . I did MD (membership group) for a year and saw improvements over a self directed whole food plant based diet of 2 years prior. It is never too late to reverse type 2 diabetes. Your gut will need a little more time than average to adjust to the new foods, so take it slow. It will need to change a lot of its micro-biome - for the good :-)
