“Keto” has been the most-searched keyword on NutritionFacts.org for months, and I didn’t have much specific to offer…until now. Be sure to subscribe to the channel to be notified of the remaining 6 videos.
Please look into Keto diet as a treatment for Chronic Fatigue Syndrome / Myalgic Encefalomyelitis . Some doctors are treating CFS/ME that way, and it would be really interesting to know if there's at least anectodal evidence that it helps.
I appreciate hearing your survey of the sum total of existing evidence regarding the ketogenic diet. I just want to arrive at the truth, no matter what it is. The work of Warburg, Seyfried, and now many others, in the application of the ketogenic diet for cancer is very exciting and potentially ground-breaking and life-saving, if true. What is the truth? Do ketones also fuel some forms of cancer?
Hitler breathes oxygen. So avoid oxygen. Cancer eats glucose. So avoid glucose. So does healthy cells do to need glucose. It was only the 1900s that we eat more sugar that every food product contains. Veggies aren't plain glucose. Ketones can't feed Hitler and Cancer though. At least not all Cancer.
My brother was diagnosed with stage 4 metastatic prostate cancer last January and within six months of being in ketosis the prostate cancer came up blank on an MRI.
@@tamcon72 hearsay is not taking a 5 mm piece of cancer and shrinking it to nothing in your prostate. Also taking a 20 mm piece of cancer in your hip bone and it reducing Down to 11 mm in 6 months. This is not antidotal these are facts. In fact the bone cancer has been shrinking every single MRI he's taken and soon he will be cancer-free. Checking your ketones two or three times a week and checking your glucose levels is very important while fighting cancer.
Scott Gabelman -- anecdotal doesn't mean non-factual. It just means that it's a single case without control for other confounding factors. People do go into remission spontaneously. Maybe it was the ketogenic diet, maybe it was coincidence. Studies typically require at least 50 people, and if the effects are subtle, sometimes hundreds or even thousands. One, ten, 20 reports like yours are interesting, and perhaps an indication that a controlled study is warranted. But they don't qualify as scientific evidence.
@@broddr honestly, I think it's only a matter of time before it's widely accepted that clean keto along with intermittent fasting is very helpful in fighting cancer (among other things)
Brian Parsons -- it may turn out that a ketogenic diet can help fight some cancers. But both my parents died of cancer, and in the process I met many other cancer patients. I have also had a dog die of liver cancer. In almost all cases in late stage cancer people (and dogs) lose their appetite and become ketogenic. You can smell the ketones on their breath. But it does nothing to slow down the cancer. Perhaps it's too late by that point, but if ketosis had any impact, I would expect that impact to be fairly consistent, regardless of what stage the cancer was at.
That was probably the worst line in the video... hey instead of changing your diet just nuke your body and kill off healthy cells, this is Dr Gregor showing his vegan bias quite strongly
Hmm. Always liked tour work but there is a lot of good research that keto helps cancer. Very good doctors who use this with amazing results on their patients.
Exactly. I truly don't understand why people keep pushing the standard American diet. It's absolutely ass-backward. The ONLY they get right is to not eat processed foods and sugar. But then tell people that 50% of their daily caloric intake should come from carbs, even thought they KNOW that carbs cause a huge spike in glucose every time it's eaten. And then we wonder why Americans are so fat and sick.
There is grey area on this subject. I am Vegan/Vegetarian and so I understand how you may be biased towards not supporting ketosis. Progressive cancer is not a normal life sustaining function. It uses normal life sustaining functions to spread and proliferate, that is why it is a tough disease. We can look at ketosis as a temporary/intermittent state to be in to reduce cancer. The majority of cancers use glucose, This is the first step to address. Next we would have to look at ketone usage and glutamine metabolism, but these are the more rare cancers. Obviously we haven't figured out how to combat it all or else we would have the cure for cancer. Diet can and is used as an adjunct. The targetting and elimination of the cancer should be part of the therapy. Apoptosis can go only so far and as we age it's ability appears to wane. Fasting has been shown to increase autophagy and apoptosis. What it boils down to is that maybe we will have to cut all normal food consumption and proceed with synthetic supply of energy that is counter to what the current cancer needs. Of course it would be difficult in cases of cancers that use multiple types of fuel but maybe manual removal of those is the way to go. Overall, there is room for ketosis within Veganism. In the far future perhaps all we will need is synthetic forms of energy and no longer consume potentially contaminated fuel sources.
I see most comments here rejoicing on the useful information, however this is conflicting with the information put out by Dr. Seyfried that cancer cells cannot use ketones as fuel, yet both this Channel and Dr. Thomas Seyfried are all legitimate peak western academic and medicine sources. Also when you fast you use Ketones, so this video goes against another video from this very site. So I get the feeling still we know absolutely nothing about what to do with Cancer. Everyone still has an agenda to preach whatever they are already preaching.
@@megavegan5791 Haha, it's all the same though. Keto, low-carb, atkins, paleo, carnivore, etc. All about running on ketones and thinking high cholesterol and saturated fat is healthy. They also all love to exploit and kill animals.
4:20 Hold on, time out, doesn't the metabolic theory of cancer treatment say that malfunctioning cancerous mitiochondria cannot use ketones as fuel but our healthy cells can? Therefore cutting off the two fuel sources to those cancerous mitochondira helps to retard their growth?
It's debatable whether any cancer can in fact use ketones as a source of fuel; but if they can, there is no question and no debate that cancer cells don't crave ketones like they do glucose. Likewise the video is disingenuous in insinuating that it's no big deal that cancer cells need to metabolize glucose because all cells need to metabolize glucose. Whoever scripted this obviously knows nothing about The Warburg Effect (bottom line is that cancer cells have an insane craving for glucose that's wildly disproportionate to what normal cells require).
I did keto and the chronic inflammation I had went away. I also dropped my body fat % to 12%. I now do keto 3 months a year. I dont claim to be 100% sure that it's all due to the keto diet. Maybe being more aware in what I eat and counting macros. I do a very clean keto, with no junk food (bacon etc) and exercise 5 days a week. After my body adjusted to keto, I actually feel a tonne better in ketosis than when I'm not. Don't knock it before you try it! If doctors were always right, we'd not be still dying from viruses, heart disease and cancer! Keto also helped my friend who was pre-diabetic as carbs spikes his blood sugar levels.
@@Nice-sm5hr Everything is all about belief. He believed that Keto would be good for him and he wanted to try it, but gave up because he believed that he couldn't afford it. He also believes that he is broke and appears to be plant-based not because he believes that it is better, but a last resort economically.
I am a lay person with an interest in this topic . Statement made here is 'all cells feed on glucose HOWEVER cancer cells are far more hungry for glucose due to over expression of HIF1 factor . Secondly switching to ketones through fasting is in line with our origins as food gatherers who lived through feast and famine . Glucose was more regulated and stable in hunter gatherers . Thirdly there have been groups of folks where no cancer is known and the diet is really an ancient food gatherer diet as well as physical activity They live to well into the 90's . Also fasting is like computer reboot to safe mode . The immune system is activated .. dodgy cells are killed off .. autophagy whereas Chemo is like using a shotgun to shoot flies and the immune system is switched off which is exactly the wrong thing to do . The only thing that allows us to live is our immune system . Its also the reason that we die .. its not cancer which kills us which is always in us somewhere anyway ( I'm convinced of that ) ... its the immune system slowly switching off and unable to make daily repairs and kill suspect cancer cells. The 'guards' must be fit and active not asleep in the fort . Isn't that why cancer is called the 'disease of the elderly ' because the 'guards are not fit and often asleep in old age ? So to live a long life do the things which boost the immune system .. exercise to boost circulation , fasting , control glucose levels, boost vitamin D with food like salmon leafy greens etc etc .. thats my view .
Flaky Amanda Fae I am doing a higher plant consumption/ plant based approach to keto, have been for 4 years. Total 120 cholesterol, perfectly healthy in blood markers, and I reversed my hereditary liver disease. Have been skinny all my life and until now gained a lot of lean mass. This is how I will eat for as long as I’m alive. I don’t consume dairy or butter
You're nuts! Ketocon speakers have walked the walk. Doctors who treat their patients with keto, and researchers who do real unbiased science. Dr. Greger would be humiliated.

@@twn5858 Government to ban what you eat? Government artificially makes animal products cheaper via subsidies and is in bed with the meat industry. Cool story bro, enjoy your heart disease, cancer, obesity, ect etc.
Exactly! Who cares if you lost weight, reversed diabetes or cured cancer by eating keto? Are you going to listen to your own insignificant anecdotal experience or the official vegan science??
Yes, let the science speak and be put out there. No issues there. Let the scientist have a ball doing their thing with the numbers, but when one person puts a certain lifestyle such as keto (Which is a whole food diet that includes lots of veggies contrary to what people believe about keto) "to the test" on their body and sees real solid results (As verified through testing with their primary care physician) on weight loss, type 2 diabetes reversal (See Sarah Hallberg clinical trial), reduction in inflammation, etc. etc. that they haven't been able to achieve with anything else, then don't rain on their success and throw the term "anecdote" out there at them. They are having real success, and it works for them. It may not work for everybody, but works for them. Cheers!
As a plant-based eater I've never been particularly "triggered" by people with different beliefs about the health of my (or their) diet. In fact, because their views are based on shakier logic, I've always suspected the keto people would be more defensive, not less. So I guess it's time to...um...put that to the test?
@@twn5858 There are different levels of "logic" and I could have been more clear, but Nutritionfacts viewers will know that I meant scientific research, not "stories". No shade - we all like things that make intuitive sense - but a story is just a hypothesis. I don't think keto as a long-term diet is going to prove out to be healthy. Short-term for weight loss maybe, but it's not looking good as a way of life.
@@twn5858 That's awesome. I know it's used for seizures too. I think the video acknowledged that there are some known medical benefits to a keto diet, but that doesn't mean it's necessarily "healthy" or optimum. As this seems to be the first in a series, I'm guessing future videos will expand on that.
@@andrewclancy2511 science vs stories. "A friend of mine drinks everyday. She has been drinking and driving most days for the last 30 years. And you know what, she has never been in an accident or been pulled over or died. So drinking and driving has worked great for her and I'm going to keep on doing it too!"
Thomas Seyfried says cancer only feeds on glucose and glutamine, not ketones. So he says you need to both go into deep ketosis and press-pulse glutamine to starve cancer.
Several relevant facts related to endocrinology and glucose metabolism have been omitted: 1. Carbohydrates are the strongest nutritional stimulator of insulin release. 2. Insulin has powerful anabolic (growth stimulating effects) and triggers other downstream effects of growth factors (e.g. IGF-1 release and m-TOR complex). This is why athletes caught in the BALCO doping scandal were using insulin. 3. Excess glucose (blood sugar) is stored in the liver as signaled by insulin, which released in response to dietary carbohydrates. That is why carbohydrates, especially high glycemic index carbs, causes non-alcoholic fatty liver disease. 4. Obese men are 60% more likely to die from prostate cancer compared to men of “normal weight.” Obesity is a direct result of errant carbohydrate metabolism called “insulin insensitivity.” It seems disingenuous to suggest ketone metabolism by the liver as a reason breast cancer tend to metastasize to the liver, while ignoring the profound liver inflammation and dysfunction caused by excess glucose. Respectfully, Joseph J. Harris
I'm 74 y.o. now and still on Keto. Lost 74lbs, the ladies can't believe I'm in my 70's. Blood work normal, I Door Dash for a living. Keto is a no brainer for old sick people.
brilliant love ye buddy im informed thanks to you much appreciated and you really have had a profound positive effect on my health i was 4 stone overweight and very unhealthy diet when i first started watching/listening to you ive now lost the 4 stone and along with it my ashma keep up the good work and THANKS FROM THE BOTTOM OF MY HEART!
My position is that we don’t quite know the long term effects of keto, so we should avoid the diet, especially long term. It could have negative effects on brain health. If you want to lose weight, eat nutrient dense, fibrous foods and excercise
Thank you, Dr. Gregger, for this information! When I first started researching plant based nutrition, I wanted to know if it would work for my daughter with epilepsy, since we had already tried and failed the modified Atkins diet (with daily ketone urine testing). Almost two years later, I am happy to say a whole-foods, plant based diet has been a blessing for all in our family, especially for me, aging and aching everywhere, now healthy and happy!! My daughter still has a few seizures a month, but is doing better and loves the food.
A few seizures a month is far from normal... Put her on carnivore for a month and she'll be healed completely. At least try if you care for her in instead of forcing your ideology on her
turns out rice only has arsenic content when grown in watered rice fields. they do this to maximise profit. if rice is grown in dry fields, and watered just like regular veggies (watered only when needed and not too much), rice tends to have ZERO arsenic.
Been low carb for a year now. Keto for about a month at the start. Lost 15 kg, have loads more energy and now all my markers for metabolic health are good. LDL increased but so did HDl and and triglycerides reduced. A1C great. I hope I never eat processed food, sugar or straight carbs again.

Marcelo Ribeiro Simões “dr Berg” lmao. He’s a chiropractor you dummy. Everything he says is complete nonsense. He’s selling you something and you like it because he says eggs bacon and grass fed meat are health foods no doubt.
Justin setting I’m 100% vegan and I have to say our species never ate just plants. We must’ve eaten s little fish eggs bugs occasional meat in most populations as well. So for credibility we must admit that. Look at apes- they almost al eat insects and some eat a little meat. Still, these were a tiny part of our dietary heritage and nothing like the eggs and bacon. Real fast chicken for lunch and steak for dinner of the SAD. Thunder gatherer thing is quite overrated- mostly gathering, and if one thinks the males were bringing back the kill for the females and sharing equally, well, that’s patently false. So half our genetic contributors probably ate 1/10 what the other half ate. I’ve never heard this argument against exaggerated hunter gatherer conclusions but must assume it’s been made many times before.
@@kbkesq Hehehehe... ...you're on plants alone and I am the dummy... ...ok, ok... Blood tests and my doctor with a wide smile asking me what am I doing to get those so beautiful results. Sadly, you plant alone eaters are following a messy New Era Movement ideology...

Sure, but that's not all it turns to. According to one of the earlier videos on this channel avocados has naturally occurring substances that kills cancer cells also. As Dr. Greger would say look at the whole food as it is a package deal. More to food than just calories and macros. Your sources matter too.
Started a semi theraputic level ketogenic diet with weekly 48 hour fasts and daily gym sessions 4 years ago alongside meds for an unsuccessful prostatectomy op. Was supposed to restart treatment after 18 months. Now 4 years and no treatment required as growth has slowed. Not a cure as i am expected to start meds again in 3 months..... Been saying that and cancelling my appointments for 4 years now, and have passed the point of expected survival. Don't know what it is, low insulin, controlled blood sugar, enhanced immune system or what, but i am a damn site healthier and fitter at 76 than the extended family members in their 50's who suffer from arthritis, type 2 diabetes, lupus etc. A Ketogenic diet for me works, and no weight problems either.
@@KarlosOrbe hi. Yes, sometimes I run it to 60 hours. It took a couple of years training, but now my body operates easily on a feast or famine basis, after 36 hours when my ketones are at max, eating becomes almost irrelevant and hunger is reduced to a "I fancy that" level. Breaking the convention of must eat continually is the trick. I would never have believed people could go for days without eating till I did my first 5 day fast. You just burn your fat for energy, pounds of it as needed.
I thought that the body was able to break down protein into glucose specifically for the brain, a process called gluconeogenesis that happens in the liver. So the brain would still be getting the glucose it requires
True, vegans have scientific evidence, ketogenic fans just have dogma. (Except for proven short-term weight loss. But a whole food plant based diet also promotes weight loss.)
YEAH KETO CREW IS BAD! VEGANS ARE GOOD! VEGANS HAVE EVIDENCE! WE'RE BETTER! THEM BAD, US GOOD! LET'S GET OUR IDENTITY WRAPPED UP IN OUR DIETARY CHOICES! Bunch of egoic idiots in these comments.
@@broddr ketogenic dogma? im curious then why was ketogenics used to treat patients with epilepsy? why is the US military using keto esthers for their navy seals? why is keto the MOST searched diet in google? why do most people who research and follow it properly lose more weight then eating a vegan diet, have a better quality of life due to being able to do more then having to feed every couple hours like most vegans, but last do you even understand what a keto diet is? cuz a lot of people have this impression of what it is and they are 100% wrong.
D Scholtz -- a ketogenic diet for epilepsy has a 40% drop out rate. That's for people (mostly children) for whom this diet can literally be lifesaving. For the average person, the dropout rate is much higher. And after they go back to their previous eating habits, they gain all that weight back. And scientific studies, both controlled feeding and observational, show that the ketogenic diet and a vegan diet have essentially identical weight loss results. And you do realize that anyone eating three meals per day and a snack or two is "eating every few hours." That's not unique to a whole food plant based diet. And the Navy is using keto esters to combat oxygen toxicity from extended deep dives. Not as a diet, or even as a regular supplement. Nice try at over generalizing. A plant based diet has hundreds of scientific studies that show many significant health benefits. Other than "bro science" the only positive scientific results for a ketogenic diet are fewer seizures for epileptics (are you an epileptic?) and short term weight loss. No doubt _some_ people who try a ketogenic diet keep the weight off. But that's true of any diet that moves people away from the high fat, high sugar standard American diet.
Every person I’ve seen on keto looks and feels fantastic, including myself vs carbs/soy/and all other horrible ingredients that people eat who call out from work, are over weight and function like a sloth. I personally have never felt better in my life and I’m 38. All my ailments have disappeared. Something good must be happening. Check your “scientific study’s” again... I bet these studies will change over time as we learn even more about keto and the human body.
I have had a nearly identical effect and came about it by accident. Around my last birthday I finally went for a checkup which I dreaded because so many aspects of my health were just plummeting. I got the lecture about diet and exercise from my doctor and a whole list of issues coming back from my blood panels and other metrics. High BP, high heart rate, peripheral neuropathy, sleep apnea, severe allergies, massive weight gain, and so on. That very day I sat down and started taking notes about myself and how my health has changed over the years. I focused on being more sedentary, drinking too much beer, and always feeling hungry despite being able to chow down on a full 1lbs. box of pasta whenever I felt like it. It came to me and without any research on dieting or nutrition that one particular food that I enjoyed eating and made semi-regularly was chili. It is something I can eat on repeat, keeps me full, and I love spicy food. At that point I focused on maintaining a calorie deficit (again, I didn't think of diets or nutrition but purely the physical reality of eating less than I am expending.) Chili also worked out great because I could make big pots of it and just measure out a consistent portion that I would have each day. (Chili w/o beans btw.) Almost immediately I started noticing changes. I didn't have a scale. I didn't check my BP or pulse. I didn't take notes about myself. I felt that just keeping up with my own personal chili diet will let me know based on how I feel. I can literally write pages of little things that I had already started to notice: more energy, better sleep, no vertigo, reduced allergies, not feeling cold and clamy when hungry, ... the list goes on. I *needed* to know why and started doing the very things that I originally felt I didn't need to do: research on dieting and nutrition. I immediately learned that I had inadvertently put my body in a state of ketosis. That was eight months ago and from that point and through today (which is why I even found this channel) I have been researching non-stop. I am 46 and have been on a rather strict keto/whole food diet (around 10-15g/day of carbs or less.) I feel *amazing*. During the holidays I saw friends and family that I hadn't seen in awhile and nearly everyone at some point told me that I look healthier, happier, stronger, etc. and not just because I looked like I had lost some (a lot) of weight. It was around this time too that I even had cashiers at some of the local markets comment or ask me about what I was doing differently. That really started to motivate me so I said screw it and bought a scale, fitness watch, some basic exercise equipment, etc. I haven't felt this healthy and energetic since I was a teenager and feeling that way literally eating all of the foods I've been told my whole life are bad for me or only good in small quantities. A typical day for me foodwise is: Breakfast: black coffee Lunch: 4-6 eggs (different styles,) 2-3oz cheese, and 1/4lbs of bacon, "bullet" coffee Dinner: 10oz NY strip, a cup each of sauteed mushrooms and vegetables, and a bottle of dry red wine Even with all of that I still haven't stabilized and am still losing weight. %90+ of my medical issues are just gone and the rest are much milder. If this is "unhealthy," I am *fine with that*. I don't believe that though... the unhealthy part.
@@Sybaris_Rex It's great that you're feeling better. But a whole bottle of wine every day? That pauses ketosis while your liver filters out the alcohol content. Also, what kind of chili do you eat? I'd imagine you make it yourself, because even chili with no beans from the supermarket has loads of carbs and a lot of them even have trans fats, which we need to stay FAR away from.
This was tremendously disappointing. I wanted a realistic discussion of keto to balance the rah-rah Bro science that seems to be all you hear on RU-vid. This was not it. Worse, this doesn't fit the reality of the improvements I see in my health (and honestly never expected). Eating keto is *not* the same as chemo, and it's disappointing that you needed to link the two, even as a joke. I switched to keto from a flexitarian whole plant-food diet, and yes I've lost a little bit of weight (18 pounds), but more importantly my back pain has disappeared. So, too has the tendonitis pain in my feet (plantar fasciitis). I'm calmer, my thinking is clearer, and last winter was the first time in over forty years that I haven't struggled with Seasonal Affective Disorder (SAD). BTW, the idea that keto involves nothing more than bacon and butter is not based in real world knowledge. My keto diet is heavy in nuts, seeds, avocados, green leafy vegetables, cruciferous vegetables, fish and seafood, and eggs. Yes, I eat beef and chicken, but not in large amounts. Keto is not a high protein diet and I get plenty of protein from nuts, seeds, and fish. No, I don't eat bacon or processed meats. And I don't eat fake sugar desserts. I choose not to eat butter, because I can't afford good quality, organic, grass fed butter. Instead, I use extra virgin olive oil and extra virgin coconut oil for cooking and baking. I eat keto, but you could just as easily (and as accurately) describe my eating as whole food and mediterranean-style as you could keto. There are people out there doing vegan keto. I chose not to, because it means depending on protein supplements and I'd rather eat whole food. Dr. Gregor I hope you take the opportunity to learn about keto, not just in order to mock it, but to find out what is really going on and why so many people are seeing improvements in their health. By taking such a biased, glib approach to this topic you are doing all of your subscribers a disservice.
To be clear, those improvement don't necessarily indicate improved health. Those are improvements in medical conditions. Like how effective cancer treatment doesn't necessarily mean it is "healthy". Note that it could still be the case that your health has improved. However, it is simply not implied by what you have said. Greger has discussed vegan keto briefly in the past. He is aware that there are multiple ways to eat keto. I think you misinterpreted what he was saying in this particular instance. I too hope he does a video about the medical benefits of keto. That would be very interesting. It looks like he has many other videos in this series. Perhaps he may still discuss plausible benefits and the various ways of doing keto. The "Are Keto Diets Safe" video should cover the types of keto food. Video series goes as such: 20. Is Keto an Effective Cancer-Fighting Diet? 21. Keto Diet Theory Put to the Test 22. Keto Diet Results for Weight Loss 23. Is Weight Loss on Ketosis Sustainable? 24. Are Keto Diets Safe? 25. Keto Diets: Muscle Growth and Bone Density 26. Does a Ketogenic Diet Help Diabetes or Make It Worse? Source: drgreger.org/collections/dvds/products/latest-in-clinical-nutrition-volume-47
You're not doing a standard ketogenic diet. You are doing more of a plant-based version, which is less pro-inflammatory. I would assume that there was something in your plant based diet--grains, perhaps?--which was pro-inflammatory to you specifically, and merely eliminating it did the larger share of work in your improvement.
Lysander... your argument is that even if a "medical condition" goes away, that my health isn't necessarily better? That's... wow. How in the world do you define good health? A complete lack of pain is one of the most compelling things I've ever experienced. Just to clarify, I lost about 18 pounds on keto over eight months. Not a trivial amount of weight, but not earth shattering either. The improvements in my health are more significant than I would expect from the amount of weight I've lost. As the saying goes, I've been heavy and I've been thin... Right now, on keto I'm still overweight. I'm in the minority in that I don't think that keto is necessarily the best way to lose weight. But, I don't care because the improvement in my health is so fantastic that I'm sticking with it anyways. BTW, 17 years as a vegetarian (2 of which were vegan) and another 10 years eating flexitarian have done absolutely nothing to resolve my plantar fasciitis, which I've had to manage with years of physiotherapy. And it's never affected (that I can tell) one way or another my struggle with Seasonal Affective Disorder, which I've had since I was a teenager.
I agree! Humor is good but no reason to be so derisive against keto. Of course there are charalatan trying to make quick bucks but there are charalatan's in plant based community too. I believe the major benefit of keto is indirectly cutting out most of unprocessed foods giving immediate improvements. Most of communities who have lived past 100 years or had long healthy life are largely plant based diets with minimal meat. Like Okinawa people, Seventh day Adventist, Ikaria, Sardina etc... No community has followed a keto diet in the entire history of human existence. Keto is a grand experiment but there are plenty of communities that survived on a largely plant based diet.
@@tamcon72 This is what frustrates the hell out of me. I *am* doing a standard ketogenic diet. A ketogenic diet is defined as a low carb, moderate protein, and high fat. That's exactly how I eat. Far too many people conflate a crappy diet with keto, because they've never bothered to figure out how real people (who are not 22 year old male RU-vid stars looking for likes) eat in the real world. No one I know eats this way in real life. And, I have two good friends who are also doing keto with me. A good quality keto diet has a lot of vegetables. For example, 5 cups of shredded kale has 4 grams of net carbs, and can and should be part of every diet. If you are doing strict keto (20 grams of carbs a day) you still have room for kale. BTW, I make one hell of a fantastic shredded-kale ceasar salad. This *IS* real world keto.
Any diet high in fat and protein Will stress out the heart, arteries, brain and kidney. I would never go on a keto diet, I have one kidney. And the kidney will have a difficult time processing all that protein, leading possibly to its own self destruction,!,!💔 Not to mention clogging of the arteries with fat leading to a very quick heart attack.💔
@@StillTrustNo1 Yes for a short period while you shift to ketone burning but it doesnt happen to everyone and its not as prolonged and doesnt damage other parts of your system. It may poison the cancer but chemo is poison.
@@clintrichardsonclintfromny203 Wrong. If you have a variation in your LPL, CETP, APOC3 or APOE SNP(Snip) then you can have REALLY dire outcomes from a fat based diet.

Consider starting a free audible account and get the book "dirty genes" to get you started with the wonderful science of SNP's - then maybe after that consider an education. Best of luck

I mean, long ago you posted about the “eco-atkins diet”, essentially a vegan keto diet, saying it had no negative effect on mortality. Now every time you talk about keto, it is all animal-based. We know the damage animal products can cause for sure. But why avoid the vegan keto topic?
In case you didn't know, Dr Greger is doing a series of videos (4 if i can remember correctly) on the keto diet, be on the lookout for those because it's impossible to do a thorough analysis in one video.
Miguel Mora probably because the majority of people aren’t vegan and aren’t keto, and the majority of the people who are vegan, are also not keto. But the people who are keto consume lots of animal products, which is why when discussing keto the focus is on the regular animal based keto diet.
Well it did say that cancers feed on ketones, a vegan ketosis is making ketones all the same, as energy, which feeds cancer all the same I would assume. However you aren't consuming carcinogenic substances that would cause the molecular damage that leads to cancers.
I don't know what to think. Keto. Not keto. Saturated fat. No saturated fat. Eliminate grains. Don't eliminate them. There never has been such a divide in the complementary health community as there is today. The problem is that many older individuals ( 50 +) don't have time to play around with their health.
But... the video pointed out that keto is not good at starving cancer cells, and some cancers spread faster during ketosis. I wouldn't have chemo either. Those are not the only 2 options, thankfully.
@@spartanshred I haven't done raw myself, but have known people who do juice fasts for a while to lose weight and they generally feel good from that. I think cooked starches are important for health/energy, but if people feel great on raw, and their bloods are good, then all power to them.
@@therebalancer7445 And there are articles suggesting that Keto may help to slow down cancer. Whoever thinks they know the answer to whether keto works for answer is fooling themselves. There isn't enough evidence to confidently suggest anything yet
@@twn5858 Here is one example of thousands. You just have to look and you will see it everywhere. www.foodandwaterwatch.org/news/taking-big-agribusiness-court-how-we%E2%80%99re-fighting-back Amazon rain forest being slashed and burned to raise livestock is a big one.
@@twn5858 I care about my friends and family that have recently got hooked on this deadly diet. I also care about really everyone. I also care about other earthlings like the animals that are force bred into existence only to be tortured and slaughter. And I care about the environment that is grossly destroyed at unbelievable rates by the unsustainable practice of animal agriculture. You mention monocrops, over 80 percent of cropland is used for animal agriculture for housing and feeding. Those are the monocrops. My whole food plant based diet consists of a large variety of beans, greens, grains, fruits, veggies, nuts, seeds, spices, herbs, and teas. If you look at the land usage chart by the intergovernmental panel on climate change you'll see how land use is divided. It's astounding how much land is used for animal agriculture. The waste alone is 2 gigatons and humans only consume 1.54 GT's of food. We already mostly eat plant based worldwide. We're running out of viable, rainfed cropland. And now the Amazon is being burnt down for cattle. Yet, if we transition to a plant based diet globally we could easily feed 118 billion more people, over 20 fold more on the same amount of land. And that's not even factoring in more advance plant agricultural practices. So, yes I care about human health, health care cost, the animals, and the world.
@@s7r49 My comment was not blasting the people doing the keto diet. My excitement is because I am studying for my masters in nutrition and I respect Dr. Greger's opinion greatly. I have been waiting for his keto videos for a long time to hear and contemplate his opinion to further my knowledge in my field of expertise. Thanks for sharing your story, depression and Crohns are two very serious afflictions and I am happy that you have turned your life around. No matter what dietary pattern we follow, we can respect each other and wish each other well. Good luck on your proposal! My finacee and I are getting married next month. :)
Can you talk about non alcoholic beer? I have been drinking NA beer for health and weight control reasons and wondering if I am still harming my body. Thanks!
@@twn5858 Your intestinal peristalsis or movement would still allow the passage of a small rock or piece of plastic, and eating a rotten apple would raise your blood sugar as well so I'm not sure why those things you stated are relevant. All foods are certainly not rotting. Especially as is the case with live foods - fruits and veggies - their enymatic activity keeps going long after they're picked from the soil. Contrarily, when an animal's body becomes a corpse or carcass, the decomposition process begins quite quickly. Ask any police officer, coroner or anyone in animal control and they'll back that up. Putrescine and cadaverine are organic endproducts of this amino acid breakdown, and their names are quite telling as to what animal flesh is - putrefying cadaver.
@@twn5858 Wrong! Fruits and vegetables are certainly alive if eaten fresh. Many in my fridge continue to try to grow, such as carrots, onions, garlic, sprouts, etc. Top food researchers observed white blood cell-like activity from the phytonutrients in vegetables attacking fungus/bacteria. Most fruits/veggies stay fine when left at room temperature for days. Try that with meat.
@@twn5858 Also keep in mind today's meat and most other food is full of toxins. Even our pets get sick eating the garbage the pet food industry is putting out now. Our planet is polluted pole to pole. Best to grow your own as much as possible.
Im no expert at anything but as someone with Diagnosed Early onset Parkinson's at the age of 38 and taking Sinemet every 5 hours going. Vegan has made me feel better walk better talk better and has made my medicine work better I'm not full blown vegan I still have Salmon once in a while but hey no one is perfect Thanks Dr Greger for making my life better and it didn't cost me a dime 😆
Then try a plant-based Keto. It does exist. These people have no idea what they're talking about. It's NOT all about eating tons of animal fats. Can you? Absolutely. Is that what most people on Keto do? Yup. But, you can still stay within the macros of a Ketogenic diet while being plant-based. Just stay away from processed garbage, sugar, and eat all low-carb veggies. If you make a big salad, put plenty of cut up avocado in it and then use plenty of olive oil as a dressing. And yeah, there is NOTHING wrong with having meat if you're feeling up for it. Some argue that you need fatty meats, but I think there needs to be a balance. SOME fatty meats but also some lean meats where you control the fat by adding your own healthy sources such as avocado, coconut, MCT, Macadamia Nut, or EV Olive oil. Certain fish like salmon, trout, sardines, etc., actually have a lot of omega 3s which are very heart healthy and exactly the kinds of fats that you want in your diet. So, if anybody ever tries to tell you that Keto is all about eating tons of protein and fatty meat like beef, bacon, cheese, etc., they are either lying to you or just don't know what they're talking about. You CAN, but the optimal way of doing Keto is NOT that.
My mother has metastatic breast cancer and her oncology doctor suggested a keto diet. As a student studying nutrition, this has been frustrating. I questioned the exact same thing pretty much when she brought it up, "but...all cells feed on sugar." Thank you for doing this research and posting!
CeliaXx99 my dad’s wife had aggressive breast cancer and had both breasts removed and went through chemotherapy. Her doctors told her that she needed to be on a very low fat diet like what Dr. Greger cited and she has carefully stuck with that. My mom on the other hand continues to do a Keto diet after breast cancer because she wasn’t given any nutritional advice and she’s just following a popular diet. The medical community really needs to be in the same page about this.
Did you ask for citations to research? You are within your rights to ask for verification. I can't imagine my mother's oncologist years ago recommending that. This was before the latest keto/carnivore insanity, mind you.
tamcon72 the low fat diet recommended for my dad’s wife is the same one cited by Dr. Greger in this video from the American Cancer Society and Oncology. My mom didn’t have any diet recommended to her; she is following the Keto diet of her own accord because she thinks it will help her lose weight. She lost weight but then gained it back, lost weight then gained it back...
I've only watched two videos so far, but it looks like this channel is primarily promoting the vegetarian lifestyle, am I right? I was wondering what you think of keto that mostly relies on plant fats, or vegan keto - which is entirely animal free? The villain here appears to be the carnivorous aspect of this diet. I have seen a lot of positive studies on the use of a ketogenic diet to help cancer. You seem to cherry pick the ones that are negative. Also, seem to be speaking on ketogenic diets in terms of a long term dietary method, but oftentimes people need to do a temporary diet change - such as, when they have cancer - so the issues that could come from years of following this wouldn't even come into play. I think chemo is great for cancer, but it's really hard on the body long term and most people don't do it for the rest of their lives.
Great informativ video as always! I have a very serious concern regarding a family member and wanted to ask for advice: Μy sister, who went plant-based vegan with me nearly 6 years ago, recently (a few months ago) decided that, because of her acne and digestive issues, going full on animal-based keto with no fruits and very limited vegetables was the best decision for her. Since then, her cravings and issues went away, her acne cleared up and she reportedly feels better and lighter than ever. Me, a curious and skeptical med student, also noticed extrem halitosis, her seemingly lethargic temper and her first ever shingles 3 months ago which accompanied a viral infection, that made her feel sick and stop exercising for several weeks. Whenever we try to talk about diet, she gets very aggressively defensive and brings up books like “Lies my doctor taught me” and how illnesses associated with western diet come from the vast amount of refined and unrefined carbohydrates consumed and not from grass fed organic meat, coconut oil (her holy grail) and other foods rich in saturated fats. She also reports studies she read about cholesterol actually being quite the opposite from harmful for the body, but rather necessary and atherosclerosis etc. being the result of inflammation correlated to high-“sugar” (=carbohydrates) consumption. All she sees in plant foods are harmful anti nutrients and insulin spiking carbs. She has spent a lot of time researching the ketogenic diet, the AIP and all their benefits for the treatment of various diseases. But the lacking evidence in actual studies really makes me question her sources. I am deeply worried about her long-term health and wanted to ask if anyone has ever faced a similar situation and how he/she dealt with it? Your fellow plant-based nutrition interested med student from Vienna.
That's tough, but she may need to bottom out before listening to reason. Some people are just too biased to look at evidence or even what's happening to their own body. FWIW, I had acne and poor digestion for most of my life and although going vegan helped, it didn't completely clear the problem, until I went Starch Solution (by Dr McDougall). Within 24 hours my acne cleared up and my digestion is so much better. Maybe she's clinging to keto because she doesn't think there's a better alternative and if she knew there was, she might listen? It makes no sense that keto would be good for digestion -- you're literally starving the good bacteria in your gut by depriving them of fiber. The halitosis is probably from all the bad bacteria proliferating. High fat is really hard on your gall bladder and animal protein is hard on your kidneys. Neither will show symptoms for years.
My mom has been doing Atkins and now Keto for many years trying to lose weight but her weight goes down then just goes back up again. Breast cancer and now a hip replacement for arthritis, and this diet is exactly what she should not be doing. It’s really sad because I love her terribly and I’ve talked with her about this being a fad diet not backed by science but I think that a lot of people believe that popularity = credibility. It’s really too bad that it’s legal for people to promote these snake oil diets.
This is classic cognitive dissonance and happened to all of us. When you invested so much energy, money and time to a particular matter (in this case a diet), it is very difficult and painful to admit that your diet is wrong even if the facts (e.g. the evidence presented here by Dr Greger) are in front of you and you will seek out keto advocates who will reinforce your belief.
Honestly I really didnt find this funny. I am plant based and an athlete I used to eat high carb I became so sick becames intollerant to all grains and beans and was bloated and tired with dark circles constantly under my eyes despite multiple supplements. I went high fat still plant based and was CURED i will never eat a "healthy whole grain" again in my life My performance is better im never bloated my dark circles are gone my anxiety is gone i feel amazing on higher fat plant based! You can do a HFLC or plant based "ketotarian" approach with cyclical healthy carbs such as sweet potatoes, plantains, squashes and seasonal fruits and do VERY WELL. My partner also has Stage 4 brain cancer - he has been on chemo and since doing a higher fat diet he has had amazing results. so the answer is NOT why keto when you can chemo because for some maybe do BOTH and DO LARGELY PLANT BASED not bacon and cheese for best results (cheese and bacon just shouldn't be consumed ever).
To be fair... Dr greger said its a treatment for the sick, not a diet for the general public. Your case truly falls into the former. also, you should continue to educate yourself. It sounds like you avoid symptoms but ignore the underlying cause. This will bite you sooner or later. Look up gojiman - a channel on gut health from a guy who could only eat like 2 foods because his gut was basically destroyed from antibiotics. There might be something you can learn for your problems.
Interesting! I had a very similar experience when I went vegan for a few months. The grains spikes my arthritis so bad to the point to where I could barely walk (And I run half marathons quite frequently). I couldn't tolerate the legumes either. So I switched to keto, and was able to achieve things that I couldn't achieve with any other diet. Cheers!
Why do so many people assume a WFPB diet _requires_ grains and beans? Sure, that route is easy and inexpensive, but all plants have _some_ protein, even cabbage. And the protein needed by an adult is relatively low. And if you need more protein, eat seeds. There are a lot of "pseudo-grain" seeds: quinoa, wild rice, buckwheat, millet, etc. And hemp seeds are high in protein, as is nutritional yeast.
Hmm. This is the first time I ever heard that cancer cells thrive off of ketones. Call me skeptical. I watched a program on the power of fasting (which puts you in ketosis by the way). In the program, a woman with breast cancer went through Chemo therapy and did much better with it while fasting as opposed to increasing her caloric intake which is the AMA recommendation. Of course, this is an anecdote and not a study. The fact remains that there is much more money to be made in new medical treatments than dietary changes such as Keto. Doctors do practice medicine after all.
Han Boetes I searched for the title and cannot find it any longer. Sorry. It was a fascinating show that discussed the religious origins of fasting, then visited a Russian clinic that treated patients with various diseases with fasting, then visited a German clinic that did the same thing and finally interviewed someone in California that did an experiment subjecting mice to chemo with half the mice on a normal diet and the other half fasting. Of the mice on a normal diet almost all died as a result of the chemo therapy. The mice which were fasting all survived and acted as if nothing happened. The woman with breast cancer knew of this experiment and wanted to try fasting during her chemo therapy and did much better while fasting.
@@joem5639 That's interesting. From what I recall radiation damages cells that are reproducing and cells need energy to reproduce. It could be that fasting simply reduces the number of cells that will be vulnerable to radiation damage. It certainly seems plausible to me.
odizzido yes, that is another way to look at it. The hypothesis reached at the end of the program is that during fasting the cells go into a protective/defensive state while the cancer cells not being able to thrive in a low glucose environment are more vulnerable to chemo radiation.
Nicecore , I’m not sure about most people but Keto to me means about 70% vegetables and low sugar fruits and 30% fats and proteins. The Atkins diet is what you’re describing.
Sorry Doc, let's agree to disagree on this one, at least to a degree. This is because there is, I believe, some confusion as to what a keto diet can be. The type of keto diet expounded on here is not the same as that promoted by some others such as the plant-based high healthy fat component keto diet promoted by Dr Jockers, which have a greater efficacy than keto diets based on 'bad' saturated fats.
@Lysander Dusseljee Nutritionfacts claims that there is no evidence showing that keto is good for people with cancer. David Turner says he disagrees and that some forms of the keto diet are good for cancer patients, so i want to see evidence for that.
Just had a friend die from breast cancer. She went keto a few years prior to her diagnosis and stuck to it during her treatments. She did holistic treatments with Hope4Cancer and when that didn’t work she did low dose chemo! So sad! Makes me angry! My little town is full of keto and a local retired chiropractor has been leading the charge!! He has her death on his hands as far as I’m concerned.
With all due respect Dr. Greger, that blurb you highlighted at 1:47, where Jesus said "this kind only comes out by prayer and fasting", was not about epilepsy, but demon possession. You wouldn't diagnose someone sight unseen; why presume to diagnose the boy in that passage from that line of text? The text doesn't support the idea that the boy had epilepsy. Is fasting known to completely drive out epilepsy such that it leaves a person? And observe that Jesus himself did not fast, nor did the boy fast, yet he cast out the thing causing the boy's condition. That might suggest that this is not actually epilepsy, but a case of a boy with a demon who got exorcised by Jesus.
This man is so intelligent!!! I wish there were more doctors like him... I fallow the not to die diet for 5 years now, and never felt better my entire life!!!
Thank you so much for making this video! More people need to know about the issues surrounding this diet. I can't wait until other videos about this come out! Thank you!
There's an equal number of PubMed journals that still support this diet for Cancer patients. The journals that Dr. Gregor has presented are not all there is about keto.
I love the comments from half-wit "keto" trolls who don't understand that atherosclerosis takes years to build up - so a calcium score a few months after they start eating grease isn't a sign that grease is healthy.
People forget that you can still be plant based and keto. This would mean lots of nuts, seeds, olives, tofu, avocado etc and leafy green vegetables and berries. Other keto diets focus on meat and processed foods. There is a fundamental difference here.
I think its unfair when people make the absolute worst assumptions concerning a diet they don't prefer while assuming the best scenario of a diet that they do choose. the anti-keto people assume that this is all about meat, cheese fried foods, etc etc etc. I eat keto and my daily diet is FULL of veggies. Its devoid of sugar processed anything, wheat flour and potatoes but massively full of zucchini, eggplant, onions, peppers, garlic, broccoli, brussel sprouts cauliflower, among others, and all sorts of green leafys, tree nuts. I don't drink milk or eat milk products I make my own sauerkraut and fermented onions and garlic I also make my own natto I get my protein from pea protein, from eggs and fish lots of avocado and olives and olive oil based dressings. The results from switching from my vegan diet of 3 years to keto as described above....i reversed my pre-diabetes, and my HDL increased by about 6 points, my LDL dropped by 43 points. so the cholesterol and pre-diabetes improved when switching from a vegan diet (with admittedly too much sugar in retrospect) to a "clean keto" diet I'm also eating in a time restricted manner (eat during a 6 hour window) The point is....if you define keto as meat meat meat meat meat then you're not being completely honest when discussing the topic
High PSA led to some prostate cancer 5 years ago ,I have always been a pretty good eater ,never processed or fast food always made my own ,I work out ,have a high metabolism ,I consider myself in good shape ,so for 5 years I never use sugar ,went from 3 beers a day to glass or 2 of wine a week,, no dairy cept a little in my morning coffee ,got off meat ,ate more fish ,veggies ,{not as much as you } also make my own S K , and the last 4 years my blood work sucks ,cholesterol is up ,glucose why up ,triglycerides up ,,,frustrating ,,meantime my brother started keto and his numbers all came down ,wtf
Keto has nothing of significant importance to do with fasting and the big picture of it’s benefits. I love Dr greger but he took fasting out of context. Starvation is not fasting. Starvation drives you to a ketogenic state...
This episode is great but not consistant with your theme of the benefits of a plant based diet. You did not stress well enough that one is less likely to get cancer if one eats unprocessed plant-based foods. You didn't refer to prior talks about huge negative effects of meat consumption such as cancer, diabetes, oxidative stress, inflammatory response, etc, etc, etc. AN ONCE OF PREVENTION IS WORTH A POUND OF CURE.
Cutting down on eating processed sugar can only be a good thing whether you have cancer or not. Here's an interesting speculation - cancer cells tend to close down or expel their mitochondria to prevent the mitochondria from detecting that the cell is cancerous and therefore suiciding the cell, cancer cells ferment their sugars as a method of digestion to fuel themselves instead of the mitochondria doing the job, processed sugar is both fructose and glucose and I think the fructose acts as a catalyst which accelerates the fermentation of the glucose component of the processed sugar molecule and therefore providing a superior fuel source to sustain cancers higher than normal growth rate, so eating less processed sugar must make less sugar available to cancer to ferment causing cancer to grow less.
Or just eat whole plant foods. Why make everything so extreme? That is what people hate about diets, they are so extreme and not sustainable. WFPB, that's it.
_Everyone_ should be fasting 10 hours every day. That's just normal behavior. You sleep for 8, so unless you are Ambien sleepwalking to your refrigerator, that's the bulk of it. And you should not be eating for at least two to three hours prior to sleep, so that's the remainder. Your brain gets through the night thanks to ketogenesis. Or did you mean extending that 10 hours with an additional 10 hours? And vegan keto is not likely to be healthy. Even mostly unsaturated olive oil causes the same blood thickening and impairment of artery dilation as animal fats. And Type 2 diabetes is caused by excess lipids in muscle and liver cells. I haven't seen any research that indicates vegetable sourced lipids are less hazardous in Type 2 diabetes than animal lipids. So my guess is that vegan keto is only a little better than standard keto, because of less _saturated_ fat. And keep in mind that coconut oil is the highest in saturated fat of any vegetable source.
Alyssa Stevens -- work off carbs? Gram for gram fat has twice the calories as carbs. If you have time to work off the fat (even counting the faster satiation keto people report) then you would need considerably less time to work off the carbs.
I do Keto along with intermittent fasting for weight loss and to reverse my insulin resistance. Once thats done im back on a very manageable intake. I have to say its working more than anything else ive tried in the past. Whats more i crave carbs and sugar WAY less once my body adapted about 3 days into it. I dont crave night snacking, or snacking in general, no sweets here, and i can pass the bread and chips now. That along w/ your body change is very exciting!
Yup! Keto really allows for going long periods in between meals. It's why that diet *truly* goes hand and hand with intermittent fasting (At this point I think all sides of the diet wars so-to-speak agree that there are definitely health benefits to intermittent fasting). It gets you out of the glucose / insulin cycling where you get hyopglycemic and have to keep eating frequently. Vegan diet is great and all, but it's not *near* as good as keto for allowing for intermittent fasting. It's proven to reverse insulin resistance and even type 2 diabetes (look up the clinical trial by Sarah Hallberg)
Same here and I switched to a whole food plant-based diet (not low carb) and intermittent fasting (1 meal per day) 4 months ago. I have finally broken my addiction to food and sugar. I have lost a lot of weight and I do not feel like I am on a diet.
The tone of your voice is really off putting.. there's a snark to it that seems completely unnecessary.. if you want to share information that's great.. but what is up with your voice dripping in attitude?
