6 Keto Myths that Need to Die

[@petertownsend252]

With respect to myths #1 (exercise) and #2 (long term sustainability), I am 60 and now thru-hiking the Appalachian Trail carnivore and OMAD (no snacks) from Georgia to Maine (2,200 trail miles). I hike in a fasted state and eat after I am done hiking for the day. I hike about 8 to 10 hours a day, covering about 12 to 15 miles wearing a 30 lb pack over steep mountainous terrain. For me, carnivore and OMAD is highly sustainable while long distance thru-hiking, as it is in my daily life. I never feel metabolically fatigued or bonk while hiking. Always feel good at the end of the day with plenty of gas left in the tank. Also, no NSAIDs, joint problems, or soreness. Always feel good in the morning and eager to start the day. I did a 4 month 1,000 mile proof of concept section hike last year, at which time I lost 14 pounds in the first 2 weeks as I was adapting to trail life and getting my trail legs, then lost only 1 more pound over the next 3.5 months. So far this year, I have been on-trail for 6 weeks and have lost only 4 pounds. No "hiker hunger", no "post-hike depression", no post-trail weight gain, no post-trail anything (other than feeling good). Most long distance thru-hikers follow the "recommended" thru-hiker diet consisting of 4,000 to 6,000 calories per day of 75% carbs, 15% protein, 15% fat (75-15-15) and tend to experience "hiker hunger", binge eating while in town, and progressive weight loss while on-trail. This is followed by post-trail depression, continued hunger, and significant weight gain after they go off-trail. Most long distance thru-hikers are sold on and indocrinated into the myth that you need a massive amount of carbs to keep your energy level up and perform. Typical thru-hikers continually snack on candy and high carb, highly processed junk food (e.g., honey buns) from morning to night. Meals are also a massive carbfest (pasta, rice, beans, tortillas, etc.). For purposes of personal interest and N=1 thru-hiking science, I am wearing a CGM to monitor blood sugar, a "Charge 6" model Fitbit monitor, and also brought my KetoMojo meter for finger stick monitoring of glucose and ketones levels. Resting heart rate is in the high 40s. Diet on trail consists of pemmican, salami, powdered eggs, and cheese. Last year, I had comprehensive blood work done after 3 months on-trail thru "Own Your Labs" and LabCorp. NMR lipid profile and Insulin Resistance score parameters were mostly all off-scale pegged to the green (low risk). Fasting insulin level was 1.2. For those interested in cancer, KetoMojo glucose/ketone index (GKI) cancer score developed by Dr Thomas Seyfried, PhD is fanstastic. GKI is typically, less than 2.0, sometimes less than 1.0. Lowest score was 0.7.

[@patricklachance6880]

Thank you for sharing your diet and hiking journey and this makes sense for our life carb community reading through this. Curious what your heart rate range is while you're hiking. I would guess zones 1 and 2 depending on your pace and topology of the terrain.

[@williambelmont9601]

Absolutely this, energy never runs out when carnivore/0 carb.

[@BeefNEggs057]

Wow, pemmican - without the dried fruit I assume. I’ve been toying with the idea of hiking again being a carnivore and there are some keto freeze dried meals out there but definitely need to steer clear of the spinach and other depression causers like nuts too. Powdered eggs, cheese, homemade jerky is what I came up with. Canned “meat” if I can deal with the weight. The beef and salt pemmican would bring in the fat to make ketones. Maybe some MCT Oil also. Crazy I’m even thinking of hiking. Sadly I’d given up on that due to feeling old. Not anymore!

I'm also 65 and in December I went Full carnivore and in 3 weeks I lost 22 lbs so I switched to a Keto and I lost a total of 37lbs and I am now at the weight I was when I was in the Military! I'm off all my blood pressure meds and feel great also.

[@jobrown8146]

That's great. I'm now 66 and have been low carb for 2.5 years. I was surprised at how quickly I started to feel improvements when I changed to low carb to remit my diabetes (which I did within 3 months). The first thing that I noticed after only about 1 week was that I was getting a better quality sleep. Even though I sometimes have difficulties sleeping due to back and knee issues which can disturb my sleep, I found that I wasn't as tired the next day. After about 3 months I had to reduce my BP drug by half, then later I had to do that again, and these days I am off completely. I am now back to my ideal weight which I haven't been since mid 1980s before children, without even trying. And amazingly my hair is not as grey as it was; when I started noticing this I had had no idea that this was possible but I have since found others online who have had the same thing happen. I wish you all the best.

But my TSH was a .5 ie hyperthyroidism (supposedly ) but I feel great I got tons of energy with none of the other accompanying symptoms so my endocrinologist just said let’s just watch it.

[@jobrown8146]

When I first started low carb I wasn't worrying about the seed oils because at that time I didn't know how bad they are. Over the last 2.5 years I've learned a lot and about 6-8 months ago I have been steering clear of them as much as possible; sometimes I will buy things like sausages which generally have them in but whereas before I was eating them regularly I now keep that sort of thing as my pseudo takeaway food (ie if I feel like something different I pick up a pack of sausages and bring them home to cook). When I've eaten something with seed oils I seem to notice a difference in how I feel. Steve of Serious Keto has mentioned that his knees stopped hurting after he changed his WOE but when he eats seed oils his knees started hurting. I wish you all the best. I've had great results too and it is well worth sticking to low carb.

Thanks, Dr. Norwitz, for doing this fair debunking of keto myths. The diet has been popular for so many years now, you would think that these myths would have been put to rest. There is so much conspiring against the keto diet - from special interest groups, like vegans and the processed food industry who garner immense revenue from high carb junk food, to those who want to harbor some outdated ideas about the supposed damaging effects of saturated fats - that we have to keep addressing these issues over and over again.

About point 2; I would add that it doesn't need to be sustainable to have very positive long lasting health affects. I have been able to prevent diabetes by going keto for months at a time every few years. My grandmother and sister both died from the direct affects of diabetes and my mother died from indirect. I have no signs of diabetes since cycling off and on keto which always astonishes my doctors. I'm convinced that simply letting my pancreas rest and resetting my insulin levels has been the key. I also believe it may help with preventing cancer, improving heart health, and preventing a myriad of other health ailments. Also, I've been studying keto and nutrition in general since I read Atkin's book in the early 90's. Your last point on using the term "keto diet" is the first time I've seen it described by someone other than me. LOL I've argued this point with many people over the years so I'm glad I have a video I can point people to now. 🙂

[@RC-qf3mp]

Ketosis can be an effect of a combination of diet and exercise, but it’s not any particular diet. A particular diet that tends to induce ketosis in an individual is a ketogenic diet with respect to that individual. That’s how I describe it.

[@jobrown8146]

I went low carb to remit my diabetes, successfully. I'm now sticking with it because I feel a lot better on it and my arthritis doesn't hurt like it used to. I'm hoping that by keeping the inflammation as low as possible that I will slow the progression and be able to keep as mobile as possible for a lot longer. Dennis Pollock of Beat Diabetes! says that his arthritis doesn't seem to be getting any worse.

[@RC-qf3mp]

@@jobrown8146 if you want to keep down inflammation, be sure to eat ‘clean’ keto and lots of fatty fish (salmon, sardines, cod liver); throw in garlic, turmeric and ginger.

I went on vacation recently and ate carbohydrates (including sugary foods). Weight gain ensued, but my LDL went from 301mg/dL to 196mg/dL. I am not lean. I now have 75 lbs to lose. From December 2022 until February 2024, I ate less than 50 grams of carbs a day and am on Mounjaro (lowest dose). Getting back off of the sugar after vacation was hard (even on Mounjaro- I am a sugar addict), and gaining 25 lbs of the 80lbs I had lost up to vacation was demoralizing, but I’m slowly decreasing my carbs and am now cold turkey on the candies, cakes, cookies, ice cream, and bread. Two bucks says my next LDL will be back up to 300mg/dL.

@@dangallagher6176 they aren't levels taken right after heart attack deaths, as the studies discuss all cause mortality, including cancer and diabetes, so this is what factored in. Having worked in hospital medical records for years, I see ENTIRE charts- just as many people have heart attacks with normal regular bloodwork (annual physicals) with LDL under 100, but interestingly the lower "regular" LDL die more frequently- and we are a big and busy hospital with a top-notch cardiology center- so it's not because we only have a few cases a year

Hi Nick Thank you so much for all your contributions and content they are so appreciated!! I think as you said the biggest (ongoing) myth of a ketogenic diet is that it is a diet high in meat and saturated fat, obviously it often can be but people have this ongoing belief that keto = meat and high levels of saturated fat.

[@newunderthesun7353]

Nicholas - you need to review Noakes' latest research about burning carbs during exercise. They tested multiple distances and levels of intensity through a full range of track type events. In no case was the amount of carbs ingested important to the performance of the athlete. They also proved that ingesting about 5 grams of carbs before an event helps the brain to cope with the anticipated load - the carbs are not consumed for energy to execute the event, they are used in the feedback loop for the brain to sort out what the muscles are doing and what they need. In all cases, and in all events, fatty acids were burned for fuel, not carbs. Carbs are not necessary for any athletic event. Once fat adapted.

PLEASE do a video about Keto and sleep 🙏🙏🙏 Why is it that some people report much better sleep on Keto (or while fasting), whereas others - like me - can't sleep at all??

I don't know if the girl in the video hit on the right answer, but it made me aware that so many people out there are struggling with the same issues...

[@BeefNEggs057]

So just fast with a stick of butter to help you sleep. Problem solved. Fat fasting is still fasting for most reasons people fast. Good Sleep is so important I think that takes priority if the sleep thing doesn’t adjust itself over time. Usually just a transition thing.

[@chrisjackson1266]

That last segment really shifted my thinking. That the sum of carb intake, activity level, and physiology determine whether one is in ketosis or not. So with that in mind, people set out to do a keto diet by cutting carbs, and it works because it brings that state of ketosis closer. Moving one variable... and probably the easiest one to move right out of the gate. Similarly, someone who doesn't change diet, but starts walking 45 minutes per day is moving the physical activity variable in a way the pushes them toward ketosis, provided they don't immediately slam 80g of carbs in the form of a Mountain Dew or something similar the moment they finish their walk. The physiology will change the slowest - but bodybuilders are working toward it because one of their core premises is the way increased muscle mass leads to a higher BMR. Bearing in mind, I've never thought about it this way until Nick touched on Ketosis being a metabolic state and not necessarily a function of some heuristic.

[@jobrown8146]

Nick explained it very well. It took me some time when I first started low carb 2.5 years ago to understand that ketosis is a metabolic state. I have an egg coffee for breakfast and think that I get into ketosis mid morning if I only drink water. However I realise that if I have a coffee with milk or a hot chocolate, then that will most likely kick me out of ketosis. These days I can mow the yard after only having an egg coffee and then water up until lunch time simply because I am fat adapted and enter ketosis. I do feel hungry a bit earlier than usual, but it's not the "I have to eat now" hunger that I used to have and I can wait until the same time for my lunch. Wishing you all the best.

[@ScienceAppliedForGood]

The 6th point was good. Indeed, to be sure that you are in ketosis you need to confirm it by measuring ketones level in breath, blood or urine. Blood measurement is the most precise one. Ketones Breath measurement is the easiest one to do, which I do personally.

[@nicknorwitzPhD]

Blood definitely most precise... according to breath meters I'm always >9mM ... lol (which I am definitely not!)

Some say carnivore is not a ketogenic diet. It seems we need clarity on what ketosis actually is. Bart kay says we are " kicked out of ketosis for a couple hours when we eat sufficient meat due to a slight rise in insulin. " but this does not make sense to say " kicked out of ketosis" i would say we may notice a slight decrease in ketone production momentarily but definitely not Kicked out of ketosis. If one is " kicked out" i assume they are entirety running on glucose. May be semantics but the terminologies seem to confuse people into thinking carnivore is nt keto. . . carnivore is definitely keto. And maybe a slight bump in insulin from eating sufficient meat due to gluconeogenisis would bring a slight decrease in ketogenisis but i refuse to use the term " kicked out of ketosis" when we eat sufficient meat.

Nick, I loved this video. I'm a 69 yr old male who ate a bad diet the first 65 years of my life producing a calcium score or 380, high BP and severe osteo arthritis. Now on mostly carnivore the last few years and numerous issues resolved except the coronary artery issue. Arthritis still not good. My concern is I am a LMHR and my cardiologist put me on Repatha which I agreed to with reservations. I don't feel as good since on it but it's hard to describe how. I'm waiting on any shread of information to know if the repatha is necessary for someone like me. I don't have forever to find the answers. I hear there is evidence older people live longer if LDL is higher. Now that my diet is radically different than the awful version I ate in my 1st 65 years maybe I don't need the drug. I wish I could know.

To highlight the first myth, there was a German study that showed that elite athletes didn't live as long as the general population and that the more dominant they were, the more their life expectancy was negatively impacted. So, when asking whether you need carbs for elite performance, it's very possible that the answer is yes but if you're looking to extend your life expectancy as much as possible, maybe not.

Take it with a pinch of salt when you see a paper being negative about Keto. They all do the same as he says they never actually do a Keto diet 20-50g net carbs. They have them on a "low carb" or "keto like" diet with like 100g of carbs then give them a load of fat to eat. If you are eating fat not in ketosis then obviously this is mimicking the standard american diet and links to poor health.

Ya it’s not Keto - they used a SAD light diet. Basically they put people on more restricted SAD diet. Low carb needs to be defined. They used “lower carb” and not “low carb” or “lowest carb” - superlatives and comparatives matter much in scientific research. They also need to define high fat - not just simply use higher fat.

Adding butter and animal fat doesn’t hurt anyones health and helps satiate everyone’s hunger. The low fat laughing stock (not a diet) is why we have obesity and diabetes everywhere. The sugar, vegetables and carbs hurt your health. Not the fat. For instance my wife started losing weight eating dinner with me. I also made her a high fat chicken salad with bacon and bacon grease (delicious). She lost a lot. Very satisfying food when it has fat. Eat less. Lose weight. Eating lean just makes you always hungry and we know that’s not sustainable.

I went on Keto and lost a bunch of weight. However, my cholesterol basically went through the ceiling. All in a matter of months. Then I decided to cut all the added saturated fats totally and I cut way back on meat. I went heavy on seafood. While HDL-C went from 75 to 65, TG went down a few more points to 45.

Don’t forget other sports benefits of keto - not bonking in endurance sports and more stable energy levels. And Phinney/Volek research and the top keto endurance athletes in ultramarathons, cycling, triathlons. There’s a different ‘carb loading’ protocol for some keto athletes in some sports. So it’s sport-specific and individual differences - but even for those athletes, the carbs they take in are drastically fewer and nothing like the conventional wisdom.

[@ebrahimshahidarshad1763]

how ?if it was so good for athlete why dont everyone go keto? Carbs will always be a better fuel for energy.

[@RC-qf3mp]

@@ebrahimshahidarshad1763 that’s a fallacy. Because everybody does X, doing not-X (Y) must be inferior. By that logic, there’d never be any progress in anything. To answer you anyway, despite having identified the fallacy, it is a matter of fact that many records in various races and trails for ultra endurance athletes have been set by keto athletes. Look it up. I gave you the names of the scientists doing the research (for decades) in my original post. Show that their research is wrong - they’ve proven that keto-adapted pro athletes oxidize fat higher than anything ever recorded in human history by carb-loading professional endurance athletes. By a mile. See Zach Bitter and Timothy Olson, Miranda Carfrae. Most athletes don’t do this because they are too indoctrinated by orthodoxy and are accustomed to carb-loading. It would take a very long time to make the switch to keto - at least six months, probably longer. It’s also well studied that keto athletes recover MUCH faster after big endurance races. And there are the countless health benefits/risks of keto vs stuffing yourself with high fructose corn syrup and other junk - like pooping your pants while racing or vomiting which is common among carb-loaders. This isn’t a debate. The science is in. Keto is better on a number of objective measures for performance and health for endurance athletes. If a particular individual does well with carb-loading, fine. It’s possible. But with risks, and the question remains whether those athletes would perform better on keto and have faster recovery times and fewer risks to overall health. Since people are carrying body fat anyway, why not use it? And using it efficiently requires adaption. And that adaption requires time. And people need to learn a whole new way of preparing food and eating it, which most don’t bother doing. The “if everybody is doing it argument” is something I’d expect from a child, you’re obviously not a scientist. In any case, many keto endurance athletes kept their diet a secret b/c it gave them an edge they don’t want others to know about. But watch videos of endurance athletes vomiting, bonking and pooping their pants - those are almost all carb-loaders. Many develop GI issues from carb loading that is only successfully treated by keto. Look it up. Facts.

You need it for the new cells as building blocks. When your body starts to heal itself, it needs high amounts of cholesterol. If you´ve got insuline resistance or t2d, you need cholesterol to heal your liver. I was diagnosed of hypothyrodism after 12 months of keto. But keto wasn´t the reason for that. My mom has it too so i had bad genes for it and the symtoms started 5 years earlier. I just didn´t know that those symptoms came with hypothyroidsm. Now i have medication for it. Yes! If you are and stay on ketosis, you are on ketogenic diet. I try to limit carbs as low as possible, but i know that i wont drop from ketosis if i would eat 50 grams of carbs a day.

What is clear; is that a few more benchmarks are needed to make sense of the data. A ketone threshold of 0.5 does not seem to have useful interpretive value.

Have any of the keto gurus looked into the fact that ketone and fatty acid oxidation produces much less CO2 than carbohydrate metabolism? According to Ray Peat this can be problematic as CO2 serves as the primary vasodilator in our bodies (nitric oxide being an emergency backup vasodilator that can cause damage in excess) and proper CO2 levels are needed to oxygenate tissues via the Bohr effect (which is the reason hyperventilation also causes mild hypoxia despite there potentially being a higher concentration of oxygen in the blood). Some of this isn’t widely recognized in mainstream medicine but neither is keto considered to be as great in the same circles. If true though, wouldn’t keto be bad for those who already have issues with producing enough CO2 and/or have excess NO?

Here's a ChatGPT summary: - The speaker created a sequel to a prior video on myths and false equivalencies, which was surprisingly well-received. - Myth 1: Athletes need carbs. The speaker clarifies that while top athletes in certain sports may benefit from carbs, the average recreational athlete does not need them to perform well once fat-adapted. - Myth 2: Keto is unsustainable. The speaker argues that many people have sustained ketogenic diets for years, and the term "unsustainable" is misleading and promotes failure. - Myth 3: Keto and longevity. The speaker states that data on diet and longevity in humans is poor, and sensational headlines about keto shortening lifespan are misleading. The focus should be on optimizing metabolic health and quality of life. - Myth 4: Lean mass hyperresponders. These are individuals who see massive increases in LDL, HDL, and low triglycerides on low-carb diets. The speaker argues that their physiology is different from those with high LDL due to genetic conditions, and LDL should be considered in the broader clinical context. - Myth 5: Keto screws up the thyroid. While keto lowers T3 levels, it does not necessarily indicate hypothyroidism. The speaker explains that low T3 in a low-carb context can be due to better thyroid sensitivity and decreased demand for thyroid hormone. - Myth 6: There is the ketogenic diet. The speaker emphasizes that ketosis is a metabolic state, not defined by a specific diet or carbohydrate threshold. Different individuals may achieve ketosis with varying carb intakes and dietary compositions. - Main message: The speaker debunks common keto myths by providing nuanced explanations and emphasizing the importance of context and individual variability.

I would argue, personally, that we don't NEED science to prove keto improves longevity--or rather, to be more accurate, the science that proves it lies in other fields, like human physiology. It's been theorized that the two best dietary markers for longevity will be high total cholesterol and low fasting insulin, both of which make sense when considering what this would mean in the context of a human body (cholesterol is one of the main components of the brain, cell membranes, and is a big precursor to hormone creation; while high fasting insulin is a symptom of chronically high blood glucose levels, which damages bodily tissue and deprives the cells of their ability to obtain energy). As someone who dabbles in the field of longevity mainly as a hobby, I would fully agree with you on longevity science being total crap. Heck, there's a strong possibility it'll never be good at all since we're trying to study things that simply cannot be proven, bare minimum, until another few decades pass. Especially if we continue focusing on calorie intake and whether a diet's predominantly animal-based or plant-based, instead of looking at stuff like chronic Randle cycle activation as well as the difference between lifespan vs healthspan and how things like nutrient bioavailability and fat adaptation factor into this, etc.
