100 thoughts on “Dr. Stephen Phinney – ‘Recent Developments in LCHF and Nutritional Ketosis’ (Part 1)

  1. I wish I could ask Dr.Steven Phinney one question.
    Great video, I always enjoy them, thanks for uploading it.

  2. amazing! The reason's I love this LCHF "Movement" have grown! After maintaining 40 or more lbs then was healthy, a few years back trying to loose weight as a vegetarian I came across "paleo" information, Robb Wolf. I immediately tried increasing my healthy fat, eliminated processed carbs at first, learned more along the way and eventually hearing about "keto" methods… I finally for what seemed like overnight lost 35 lbs. and feel human.

    In the world of business the bad companies are winning so I'm sooooo thrilled about hearing a profit making company based on healthy science blossom and succeed. The reality is you'll be profitable and helping much needed diabetics and prediabetics out there…. People seem to be okay with Coke in our schools but when a company tries to be profitable and truly help others folks (only a minority for sure) think it suspicious…. Good Luck!!! We can't wait to hear of your seccesses… I went to the website and I'll be watching for the time you get on facebook to follow…

  3. How long before this becomes mainstream? millions of people are sick and getting sick,who should not be. how long before giving children a drink containing sugar is considered child abuse? Good parents would not give children a cigarette ! And yet a toxic diet is common place. Our governments are asleep ,i find it difficult to understand why. The cost benefits to our health services alone would be Billions! what happened to the online petition many of us signed over the sugar tax, Jamie Oliver we need you to keep shouting about this. The Government response is to introduce a sugar tax in 2018 or some time in the future. We need action now! Why wait? WHY?

  4. wow! Great stuff…and only half way into it.

    This is why I left vegetarianism. At around 31 minutes into it he calmly points out that for yet unknown reasons some people in ketosis can "flirt" with higher (although still in normal range) blood sugar levels which is opposite to what not only what they usually find but also opposite to what they would anticipate. He and others have indicated these anomoliies too. Leaders in other eating energy sourcing "diets" especially the vegetarian community would nearly never discuss possible weakness in their approach… not to mention do actual research studies …. There is still so much to learn and asking questions, pointing out weak spots or unknowns is what I'd consider a more science approach … thank you again….

  5. Can't wait for part 2! I really liked that last question about how if you're adapted and mess up it's not the end of the world. Just do your best not to continually mess up and fall back into old habits. But if you do you'll find your way back with greater appreciation for what keto is. 😀 Unfortunate that we didn't get to hear his views on intermittent fasting though. I know him and Jason Fung disagree on some points.

  6. This stuff is like gold. I'll just add my voice to those clamouring for part 2. I have to say a huge thank you to LCDU for publishing all these videos (& arranging the conferences?) because 'up top' here in Scotland we are nowhere near as far forward in our thinking about low carb & our health problems associated with heart disease & diabetes are among the worst in the world. Personally speaking, every single member of my family on my father's side (including him) have died from an illness associated with these conditions. I'm doing my best to break that trend…

  7. if you've done keto for over a year is it not true that you utilize them better to where you might not be in a state of NK (no blood ketone levels)?

  8. Dr. Stephen Phinney is a total mensch and I am immensely grateful for his work and continued willingness to teach and learn about ways to heal our metabolic derangements. Easy to listen to him for hours. Looks like we will have that chance!

  9. While I love Phinney my mind screams that we are still going about this all wrong.The world must re-engineer the foods that are easy to produce and most of the world would love to be able to eat without ill effects.This food is carbohydrate based food.If we altered a large part of present day carb foods in a bad way we should now start altering them into more healthful options.

  10. As he talks about things being science based. Can he quote a study that a diet high in fat and low in carbs reversing heart disease? As I can quote a study showing that a low fat whole plant food diet reversing cardiovascular disease. Dr Dean Ornish published a randomised clinical study showing it possible to reverse heart disease on a plant base diet, low fat. And type 2 diabetes is caused by fat not sugar, I am not surprised this guy never became a professor.

  11. Yes, Yes, Yes, around the 32 minute point Dr. Phinney tells the story of people purposely eating a starvation diet being given insulin to lower their blood glucose to the point that they should go into a coma. But they don't. Thus, the brain can work well with nearly no glucose in the brain.

    That proves what I've been saying for some time. One of the main reasons for insulin dependent diabetics to eat low carb or a keto diet is that very low blood sugars would affect their mental and motor capacity only marginally and would prevent most comas. (Of course, I must point out that driving while having your mental and motor skills marginally impaired is very dangerous and should be avoided.)

    As a T1D for 51 years, I've been eating a low carb diet since 2004. Since then I've had way to many blood sugars below the 50 mg/dl and a few times below 40. During those times I functioned well enough to test, find food and eat it. I've even conducted a meeting and tested my sugar afterwards and it was like 47.

  12. I've had four heart attacks, the first 22 1/2 years ago at the age of 39 and my dad died of a heart attack at 33.  He was a fit fighter pilot who had just passed a physical to fly for United Airlines and I've always been active and fit.  I have FH type IIa (TC 325, HDL 24, TG 175 while on a high carb diet).  That TG / HDL ratio over 7 is a serious problem.  Dr. Phinney is the first person I've seen, to diagnose that correctly as metabolic syndrome.  I decided about six years ago that my problem was really a form of diabetes and not CVD/heart disease.  The only times I've had my sugar tested it came in at 5.5 HBa1c and that was after I'd already been on a relatively low carb diet.  And now on a very low carb diet, I generally test at about 112 on a blood glucose meter, which I believe would still be about 5.5 HBa1c.  Most Physicians would say that is OK, but according to Dr.Richard K. Bernstein, he's seen diabetic complications with HBa1c of 5.7 and he thinks 4.6 is optimum.  Dr. Phinney mentions getting down to 5.7 or 5.9 in this video.  That may be OK for some, but certainly for me, and others who have high TC and TG/HDL ratios above 2, that would be high enough to cause arterial damage.  Since going nearly Zero Carb, I seem to be getting better and the arteries seem to be healing.  I say that because my angina is decreasing and I've been able to resume exercising again.  I've been dealing with angina for the last thirteen years or so and had stopped exercising completely for over three years because just about any exertion at all would bring on angina.  I might mention that on a very low carb, high fat diet my TC is about 400, HDL 69 and TG 58.  I like that HDL number and ratio of under 1 to 1.

  13. @ 41:10 Dr. Phinney believes in the old "Calories IN, Calories OUT" theory ?… Weird.
    I'm a believer in LCHF but why bother with a LCHF diet if it's all about calories ? 😉
    I'm very surprised at Steven saying this because many experts & Doctors in the LCHF world agree that calories mean nothing.

  14. Check out the work of Dr. Jason Fung from Toronto, Canada: "Aeteology of Obesity" and also "Intermittent fasting".

  15. +David Lomm

    He's not referring to the calories in/out paradigm as the necessary precondition for being weight stable (which states that quantity is the most important factor, irrespective of what the different "diets" in the market consist of), but rather to the notion that, once you're ketoadapted and weight-stable, your body can perfectly rely on external sources of fat/protein without undergoing changes in its composition, even if you're a high performance athlete. That's mostly the point: keto works for high performance sports.

    He's not saying that if they had eaten more calories they would have gotten fatter, but rather that the body could rely on that source of calories, given that they ate what they burned, without wasting muscle and losing lean body mass, which is a major concern for sportsmen.

    And the calories in/out thing is redundant, because LCHF proponents state that the body regains the ability to regulate how much it needs from an external source. Nobody said that calories "mean nothing", but rather that counting calories is useless for weight loss, because different metabolic types react differently to different types of food, which leads to inconsistent results.

  16. I watched Dr. Stephen on Low Carb Down Under (Sept 2014/15?), and thought: "Eat tons of FAT and get SKINNY? Like ingesting 24 beers in a night was a bad idea, well I've put worse in this body, so why not!"
    I was 250 pounds, and then in 6 -8 weeks, the scale reads 220? The look of confusion on my face was priceless. WTH! How is this possible? By 4 months sub 200! At 6 foot tall this is an awesome weight, a few more pounds and BINGO 6 pack, because I can start to see them !!!!!

  17. It takes a while to wrap your brain around this because of all the faulty programming received, and that's still being pushed. I just finished 3 months and compared bloodwork from LCHF versus what was essentially a low fat diet chopped full of lentils, brown rice, salads, chicken, fish…
    Well, my results were shocking even though I've seen enough videos to convince me it would work. However, I encourage skeptics to test their blood, and open your mind. My risks decreased (they were never high) on a diet full of healthy, while fats. I eat so many things I used to avoid. I'm satiated and here's the real news. I lost 14 pounds, and exercise less. I did not lose one pound while on a low fat, high carb (but still "good" carb diet…like sweet potatoes, brown rice, lentils, et cetera) diet. Again, test yourself. I'm convinced. Thinking of a tattoo HF for life!

  18. Under what circumstances in nature would humans have had ketogenic diets? The closest I can think of is eskimos, and their health is crap.

    A priori, known science excluded, one could argue that a ketogenic diet might work. But given what we know about the consequences of fats on the arteries, ketogenic diets make no sense. Switch from sugars to produce, so you avoid the deadly side effects of keto diets.

  19. Here's the source of your problems as described by Dr Phinney in the part 2 of this video: "Our guidelines in the United States are based on ideology not science and its sad that we can't penetrate that titanium shield of certainty."

  20. I had to check into the ER with a racing heart beat, palpitations and weakness in my legs about 3 weeks into my ketogenic diet, I thought I was having a heart attack but after ECG, blood tests and chest x-rays I was given the all clear. The nurse said my blood sugar had plummeted, I hadn't been exercising or anything and I got hypoglycemia symptoms on and off for the first 3-5 weeks. I'm approaching my tenth week now and don't get the symptoms anymore, I had a blood panel done and my Triglycerides dropped from 1.1mmol to 0.8mmol, my Erythrocyte Sedimentation Rate dropped from 18 (it's been high every blood test I've had for over 5 years, I've battled with inflammation for a long time) down to 5 which is pretty incredible. My fasting blood glucose is 5.0, used to be elevated prior to the diet. LDL has increased although HDL also increased, total cholesterol went from 5.1 to 5.4mmol so I'm working on increasing unsaturated fat intake and exercise.

  21. Did his diet combined with Intermittent Fasting. Was doing great, lost a lot of weight. No longer needed to take insulin (I'm type 2), but then after a couple months my ketones were in the purple and my uric acid levels went up really high. I had a hard time urinating — felt like I had to go all the time but only a few drops came out. Also, I got gout joint pains all over my body, for the first time, all at once.. again just after 2 months on this diet plus intermittent fasting. So I had to abort and I haven't lost weight since and blood sugars are back up. Very depressing. I suppose I should see a bariatric physician and have them monitor me and my uric acid, if I attempt this agian.

  22. at around 34:00 you talk about salt dropping in body… I went on a low carb high fat diet for about 4 months and lost 30 lbs. some where around month 3 I notice I was adding salt to everything I was eating… I thought it was due to not getting the sodium from processed foods but it makes… my doctor didn't have answer… my point is that when you need the sodium your body will let you know through taste at least that's my experience…I just began back on this diet and am going through day 2 and have headache from what I think is lack or the with draw from sugar

  23. I have fibromyalgia so this should be a good experiment for me. I have been on the Keto diet for 3 weeks so far and down 13 lbs. This has not been a hard diet for me. I feel I'm in control of my life now.

  24. Really appreciate the subtitles for the questions people were asking. Thanks a lot for taking the effort to do that for us.

  25. even if there is an app, will people stick to it? how expensive will it be to take blood sugar and ketone measurements?

  26. I still don't understand how keto is better when it is not our default setting?
    We see that people in extremely cold climates would naturally have a high-fat diet, but man originated in tropical zones; forests were probably our first and primary habitat and carbs would have been our primary source of energy.

  27. at minutes 53
    they ask about fibromyalgia and being ketogenic
    I myself was diagnosed three years ago with fibromyalgia and I have managed to be under 20 grams of carbs for the past 5 weeks
    I stopped hurting in my third week
    I've not had any pain in my joints or skin or muscles sense week three
    I believe it is inflammation and the ketogenic diet is non inflammoratoy​
    I love the fact that I now experience life without discomfort due to inflammation
    this will be my diet for the rest of my life
    I'm so blessed to have stumbled onto the info

  28. 1. Loren Cordain is fat and sick
    2. Atkins died 40 lbs over weight and with advanced atheroclerosis
    3. Coffee and other drugs has a strong effect on the illusion of energy
    4. No one following this diet has GOOD bloodwork

    I did paleo and ate tons of meat and fat years ago and also did ok. However, my bloodwork was shit. Many other biomarkers were terrible as well. Up the plant foods people: save your health, the animals, and the environment in the process.

  29. This guy is my hero and the guy who uploaded all those fantastic videos deserves a medal too! Thank you!

  30. I have wondered every since I started LCHF/Keto why others don't back it up for just the Health affects .. Yes grains are where the money is only those are the cheapest foods too . Well I should also say easiest to prepare and eat . Being 3 years on my Keto journey what I hear the most is I can't afford those foods or I don't have time to cook them from scratch . Toss a sandwich or frozen pizza at the family and call it a meal — Very Sad 🙁 Not sure if I would of been able price wise or willing to do it for my family of 4 either . If I hadn't been single I may of never tried …. Sure am Happy I did !!!

  31. Thanks Dr. Phinney, a fan of yours and Dr. Volek … and evidence is building up – since many simply now know refined carbs are "Zero Nutrition" …
    www.70GoingOn100.com the Centenarian Diet, or maybe 128, the Hayflick limit, … or if a Ray Kurzweil fan then this is a Moot Point …
    Ref, the Obesogenic Diet – https://www.70goingon100.com/the-obesogenic-diet.html#addiction
    Interesting Dr. Phinney, will see where Virta Health goes – http://blog.virtahealth.com, but of course there is the DietDoctors.com – and Dr. Westman's clinics, and the CharlieFoundation.com

  32. 5 months on Keto down 100 pounds and I no longer have IBS, brain fog, joint pain, or any other issue. The way I eat makes you feel like Superman. That and Vitamin D3 & Vitamin B12 😉

  33. I'd love to see a debate with Dr. Stephen Phinney and Dr. Garth Davis (Vegan Advocate that says Diabetes is not caused by Sugar & Carbs but by Animal Proteins and Fats lol Ikr?)

  34. The Maasai eat a lot of fat, but they do get carbohydrates from milk. Eight ounces of whole milk has ten grams of carbohydrates. They also drink blood. In addition, they occasionally eat fruit and starch. Animals are only slaughtered and eaten on special occasions, where they eat a lot of meat in one sitting.

  35. Dr. Stephen Phinney is my guy. Thanks for this, even though I'm a year late.
    I ate too much protein while on keto doing a bodybuilder program and the excess = glucose from gluconeogenisis.
    It wasn't until listening to Dr Fung that I realized the protein raised insulin too, and how bad that was. My LDL-P shot up!

  36. Thank You so much Dr. Phinney! Indeed we are dealing with "the religion of nutrition", among other pernicious if not virtually criminal mainstream "medical" fallacies….. Thanks Again and Please do continue your stellar work! 🙂

  37. hello I am type two diabetic I do the interment fasting and have no problem with control of sugar levels I know type one that eats 24 banana a day and that was once though unthinkable

  38. I reversed my T2DM and NAFLD in 3 months, cutting out most starch and sugar, on the LCHF approach, I am a family doctor.

  39. Tutti Bravo! Thank you for being another voice on Utube on the subject of Keto. Excellent addition to the mix.

  40. For anyone who is reasonably medically awake with ketosis being just one part of the puzzle I'm sure your ears pricked up when at 17:15 he mentioned ketoacidosis being the result of an autoimmune disease of the pancreas.
    We all know that autoimmune disease is one of the obfuscated medical terms for vaccine induced injury.
    Aluminum adjuvants when injected into the body do not only exacerbate the immune response for the injected pathogen (inert or attenuated) but can and do also cause the immune system to react to the body's own DNA and cellular matter.

  41. I have be following Dr  Phinney LCHF dietary advice for just over 1 year now and I recently had my blood work done and was happy to find that all my bio markers have improved especially my lipid profile my HDL was 2.1 which is better than the average . The fact that I have bee consuming a lot more cholesterol foods while on LCHF my lipids  have vastly improved from the prior years of not being on LCHF. I have lost over 30lbs of body fat and my athletic performance as a swimmer and cyclist has improved ,I am swimming events that for years I could not achieve on a high carb lifestyle.

  42. On 'intermittent fasting', in another video, Dr. Phinney states that in his view, fasting up to 16 hours a day is no problem- referring to a water-only fast. He expressed concern about people getting enough sodium, magnesium, and potassium – which people generally get from leafy greens and meats. Longer fasts with bone broth (ideally homemade from 100% grassfed meats or pastured poultry) avoid the mineral issues, as the minerals are available in the broth.

    Dr. Fung and his partner in Intensive Dietary Interventions, Ms Ramos, have presented research at conferences in 2018 and 2019 that show that the 'lean mass' loss in those following their fasting protocols is primarily excess connective tissue, skin, etc that the body no longer needs as it looses weight – and that little or no muscle mass is lost. Those interested in this approach should look up those presentations.

  43. Some stevia extracts are excellent sweeteners WITHOUT the funny aftertaste. Nutri Medix brand tastes good to us – or grow stevia and leave out the stems, as most of the bitter aftertaste comes from the stems.

    Small servings of low-sugar fruits like blueberries and blackberries are usually tolerated without spiking blood sugar or insulin release.

    For many, eating any sweets prolongs the addiction. The sweet flavor may also trigger insulin production, which will negate much of the benefit of a low-carb diet, may block ketosis, and may block weight loss… among other negative effects.

    The consumption of synthetic chemical sweeteners should, obviously, be avoided. Dr. Mercola's website has loads of info on the topic, with references.

  44. Dr.Phinney deeply appreciate this video and the others very good speaker want buy your book i have a slow metabolism & don't want to lose muscle can you help me to improve my metabolism. Thanks so very very much.

  45. I have suffered with joint pain in my knees and ankles for ten years now, having to take anti inflammatory tablets all this time.

    I went on to a low carb diet and two months later I am pain free for the first time in ten years!

    I have also lost 5kg in the process and feel great 😎

  46. This has kind of diet has been around forever. My grandma was still wearing a bikini at 62 years old. She'd tell me to eat meat to lose pounds and veggies to lose inches. And she'd always tell me to stay away from carbs and sugars. 😀

  47. I had PCOS diagnosed as an obese teen and was told I’d never get pregnant. Within 3 months of giving up sugar (before I knew about lchf – just eliminated sugar after learning about Dr. Lustigs research), I was pregnant with my first son. He’s now a healthy 2 year old.
    No signs of PCOS after though I kept eating bread and carbs. Ran miles everyday to maintain any weight loss and put a lot of stress on myself.
    My second pregnancy lead to extreme weight gain (antidepressants were a leading factor), and I gave into sugar cravings which made it worse. Once I failed the first glucose screening, I decided to try the lchf diet (with my doctors approval) and passed the second diabetes test within perfect range. I immediately stopped gaining weight and my baby is still growing, active, and the doctors are happy with the progress.
    I’m hopeful after his birth (in just a few days!!) that I will continue to lose weight and find a healthy range for my body that doesn’t require hours of painful exercise every day.
    I also discovered a wheat allergy. I’ve been taking antihistamines to combat unexplained rash (diagnosed as urticaria which is a fancy word for hives) that were associated with heat, pressure, and stress. Once I eliminated the wheat, the near constant itchy rash was gone. I still take the meds for stress sometimes but I’m no longer taking them four times a day.
    My family has changed along with me and besides the initial sadness over the loss of favorite snacks, everyone enjoys the richer foods and my toddler has finally opened up to trying new varieties which is a big shift from only eating whole wheat waffles and sandwiches.
    If only I could convince the rest of my metabolically ill family that insulin and statins aren’t the way to health when you are morbidly obese and you aren’t going to exercise your way thin… I know this not only from experience but from the hours of lectures I’ve seen (almost 10 months pregnant at home with a toddler – I needed an intellectual fix and I’m grateful for the knowledge) from doctors explaining over 150 years of data driven science that has been neglected while the masses follow recommendations given by the Agricultural industry.

  48. No one answers me!! Does the ketogenic diet (in a fully adapted after a period like 6 months of training and very carefully to the quality of foods) will improve the performance of distance runners below the marathon like (5km-10km)?
    Nobody respons I need the answer!!
    1- Virta team
    2- Dr Berg
    3- Thomas Delaware
    No one have read my inquiry did answer me.

  49. 6 months in Keto, 1 month into it no more Fibromyalgia, Fibro fog, IBS, contanstly tired, PMS, headaches. I’m trying to educate doctors that said everything was in my head… I’m full of energy, doing exercise I’m excited by life again. My immense gratitude to the researches who still fighting against main stream stupid believes, and that allow me to fix my health.
    To everyone looking for an answer to their inexplicable health problems this may be your solution as was mine.❤️

  50. I am a type 2 diabetic on insulin long-term and short-term. Is there any curriculum anywhere that I can find to help me on my journey to a healthy keto diet? I have purchased your book but have not yet received it so I don't know what's in it. I keep hearing over and over that this is almost impossible for me because I'm diabetic? Can you help, help, help, please
