Hi Doc! Really enjoy your videos for their content! I was a 23yr smoker...quit in '92. After that, replaced with lots of sugar and carbs...baked goods etc. I put on a lot of weight, became T2D, and at one point was told by my primary that I had a fatty liver. I started keto/carnivore March 2019, lost 40lbs and got my diabetes under control! I had a CAC done last February and got a score of ZERO: took myself off my diabetes meds and am awaiting results of lab tests done 2 days ago! I can't tell you how much I have taken away from your videos! You put it out there with no BS! Please continue what you are doing...I am a Patreon subscriber and really enjoy your videos! Thanks again!

GOOD one, Doc! I smoked from when I was about 12 until I was about 30. SO thankful I broke free! I've kicked alcohol, too, and now I'm on a journey to kick-the-carbs-to-the-curb FOREVER!

I looked up the article you mentioned, PMID: 25979079, and it is as scary as you suggested. In early 1961, my maternal grandfather had a CABG and was told by his surgeon that his routine bacon and eggs breakfast and cream in his coffee were directly responsible for the plaque. He, and I, then switched to cereal and blue milk and tossed out the salt shakers. Funny, his smoking was never mentioned. And I became a diabetic.

I smoked for 30+ years along with bad diet and paid the price 3 yrs ago when I was 98% blocked in my widow maker at age 51 😞 Been smoke free for 3 yrs and this year starting learning about Keto .. gone strict Ketovore / carnivore almost 3 months in .. best thing I did! Thank you for all you, Neisha Berry, Nurse Cindy and Dr Ken Berry do for me! 😁

I LOVE your calm, intelligent delivery!! I also love that you're speaking the truth to counteract all the media hype of products that are REALLY BAD for us!!!! Keep it up please-----what a delightful service. :-)

I have never heard the process described this way before, and in a way that I can understand. Thank you, Dr. Cywes!

Oh dear Doc. Very interesting today - thank you🙏 I was a smoker for 42 years(since high school), And now, I am a happy non-smoker since 4 years. I was also a carb addict (never obese) and as you say, I will always be but now, I am enjoying real food with high fat, no carb, no starch nor grains. More over I turned to be your #1 fan and carnivore friendly (also on Patrion). Hearing you today, made me wonder (actually scared), about the damage might been left in blood vessels.. Please tell us more about the life after; what/how can be done..if anything at all.

Vaping is it just as dangerous u r a gem to have in our lives I have never smoked but a carb addict thanks to u and keto I am changing my life .. U were born to teach.

Quit dipping Copenhagen last winter. Don't regret it. Trying to quit carbs.

Another great video! I love how you are stern and don’t mince words but your care and compassion for people and their health shines through.

Beautifully explained! I have changed my carb addiction but not my nicotine dependency. Dysfunctional emotional management, just as it is with carbohydrates, is what I take away from this video. Now maybe I can address the real issue and have optimal health. Thank you 🙏

Thank you for this. This is the last unhealthy crutch that I have, using vaping to quite smoking cigarettes. I've been on the ketogenic lifestyle for about 10 months now, which has helped me lose my last 30lbs and substantially improved my health and how i feel on a daily basis. I will now start weaning myself off of this toxic habit. Thank you so much for this information and helping me understand how nicotine affects us.

Thank you ❤. Your passion speaks to my heart and helps drive home how important what your saying is and how you just want people to listen and be healthy ❤❤. I used to be a smoker. Started at about age 16 in 1999 quit in January 2019 at age 35 when I had a spontaneous pneumothorax. Haven't looked back. My kids are teens and I would bang their heads together if they vaped. I can not express my gratitude enough for your help in quitting my carb addiction also. It's not perfect. But, im 90% better than I was 4 months ago. My blood work is improving. My non alcoholic fatty liver is improving, my diabetes is improving. You have been instrumental in my success ❤

Your content is so on point. I appreciate your work so very much. You may already be aware, but the origins of the word "doctor" is teacher. You are a brilliant doctor/teacher.

Hi Rob, Michael here from Jo'burg, I found this video profound. Here's why, I have chronic fituallising Crohn's disease, am under the care of Peter Barrow at Wits Donald Gordon. Had been on Humera, then switched to Entiviyo, which blocks epithelial permiability, and bang a miricle happen. Having been nearly obese, in lockdown, when I found you, I started with mind exercise and started to lose weight, so having listened to you I started to cut back sugars, more weight loss. 17 kilos so far. Have just started to cut carbs, and more weight loss. Fasting sugars 4.7. Anyway trying to cut more carbs. Can you look at this issue of too many carbs in the colon, and how this can relate to Crohn's. All the best.

Wonderful information, thank you for sharing! Quitting all our vises/addictions is so damn hard!

Thank you for sharing your endless knowledge with all of us!! You are the best!

Its so sad that in my country they sell cigarettes so cheaply even kids can buy em in retail and often those kids smoke hiding from their parents :(

The fact that nicotine can cause the formation of arterial plaque was new to me. Great info about the dangers of vaping.

This is the first time on KZfaq, that I have seen, that described the endothelial cells and what they do when exposed to nicotine. I hope I'll find another talk of yours that details how those cells react to excessive sugar an carb consumption. Excellent talk; I am new on the journey to low or no carb/sugar, caused by my almost pre-diabetic blood sugar. Rising every year. AND MY OBVIOUS SUGAR ADDICTION. Which is my real problem. My adult son said, "Mom, since when did you become such a sugar hound?"

Thank you Rob for your continued teaching and perseverance of the truth. God bless you.

Thank you for EXPLAINING the biology!!! 💋💋💋💋💋💋💋

My generation is so lucky to have all this information! Im 24 and ive already dealt with prediabetes, smoking, and wanting to be long term carnivore. Just gotta deal with the vaping and activity which are works in progress!

Thank you for this information Dr Cywes, it will certainly be shared.

,,,excellent presentation Dr. Cywes.

VERY good discussion! One of my five kids still smokes/vapes, but he can't let go. He needs different coping skills but is not actively working on that. I'm sharing this video with him.

Thank you so much Dr. Cywes. My gratitude to your work and effort.

Once again an exceptional explanation on this topic !!! Thanks Doc 👍🏻👏🏻👏🏻👏🏻💫👌🏼

22 year smoker. 13 years free! Two things I tell my wife. Wish I had never smoked and wished I had always eaten like I do now 90% carnivore 10% keto. Year ago I had a 383 CAC. Heart doc said it’s on the outside of the artery.. Not a worry. Guess we will see! Doc, you do so much for people.

Thank you. This information is vital.

Sad carnivore vaper here. Mentally preparing to remove nicotine. Thanks for this, pushing me to quit vaping. I don't regret it though I needed it for the short term as I fat adapted.

Thanks so much for that lesson.

Keep bringing the 🔨 You're doing great work on this channel. 🎓🎓💣

Thanks for telling it like it is! The problem I have is getting the massage over to a 13 year old who knows it all, and is surrounded by other kids boasting about how good vaping is! What I need is a very short simple, graphic, attention grabbing video, which gets a hard hitting message over in no more than three sentences. It also needs a title like - "Vaping is Fun" to get a 'teens' attention. I'm 75 years old with a technical background in health care, and I can follow your videos with interest. Unfortunately the audience you need to reach is 13 and is not interested.

I learn so much from you Doc! Keep up the good work! Thank you!!!!

What damage has all the second hand smoke done that I had to inhale because of my Dad was a heavy smoker when I was growing up!? 😬 I remember when going on long drives how the smoke would billow to the back seats where us kids sat. Also, no seat belts those days - but by God’s grace, we are still here 😅

This was an excellent video even for those who do not use nicotine. The anatomy and physiology lesson in and of itself was worth it. Thanks so much for what you do!!

Hi Dr Cywes, what would the effect of THC in cannabis be on the vascular system?

My buddy says vaping is much healthier than cigarettes because of all the chemicals in tobacco. I told him to think about that for a second.........he stopped vaping.

Does the same thing happen with marijuana use or do we know that answer yet? Thank you for awesome videos! I always learn so much from you.

Your attitude against nicotine and vaping is the same as most doctors attitude against eating fat.

Thank you for this video. It is the best description and conversation I’ve seen on this topic. Nicotine☠️carbs☠️sugar☠️

Of all things nicotine has been the hardest for me to quit... This is how stress kills.. When you handle it in unhealthy ways =/

Thank you for this brilliant presentation. Please address the effects of nicotine in gum or patch form, which I would assume are similar, except for striking the coronary arteries first. A very close relative is addicted to nicotine gum, and I am so worried.

Great video doc.

6:16 Paul Hardcastle did a song about that fact.

You said coronary vessels cause strokes and MI. Isn’t it the cervical arteries that cause stroke?

Hi, Mr. Cywes. I have seen almost all you videos - thank you. It's very informative, and very content-dense, without usual b.s. seen elsewhere, where personal believes are mixed with shallow science and being sold as universal cure. There is one question though, I would like to ask you. Mr. Cywes, would you recommend keto diet and IF for very skinny, slender frame person? Someone very alike actor DJ Qualls, but with hypothyroidism instead of a cancer?

Thank you Dr, Vaping is a nightmare. I smoked for 10 years and began vaping since 2010 and now I guarantee I take way more nicotine than when I smoked tobacco. I vape all day indoor or out because I feel that is doesn’t smell up like smoke. My question is in instances like people who live in the Mediterranean region and are shown to be healthier yet are heavy smokers.

Will nicotine gum or patches have the same deleterious effects?? I’m using nicotine gum to help quit smoking and feel I may need them long term to be successful...

Where can we find this nicotine study that you talk about, for further reading?

Weed is nice though & we skinny & exercise, 🚴‍♀️ words do hurt people's y they smoke stuff ! be nice ok heart's are listening, 💝

How does it take to heal from vaping and smoking cigarettes?

What about Tobacco in the gums like snuff. Tobacco in the lip like Cowboys do! Can you include this discussion

Do you have an opinion on peripheral plaque from a never smoker, untreated hashimotos hypothyroidism for years. Some concept of high tsh affecting lipids etc? Moderate to low carb, some animal products diet

Made me think? This made me Cry, Its insane & a crime what the food & drug companies get away with. .

Nicontine was always assoc w/cancer, never thought to study effect on vascular cell walls, what about caffeine? Also addictive, never associated with anything, was it ever tested for it's effect on vascular cell walls??????

What about Nicotine use in gum or losenges? It's useful for appetite suppression and has a thermogenic effect with caffeine....

Another video that's great!

Are the varicose veins connected with carbohydrate consumtion and smoking?? I cannot find the official link...🤔🙏🏽

Stopping vaping is soooooo hard. Much more than cigarettes!!!

As a former smoker then vaper I used vaping as a way of weaning myself off of nicotine as I could reduce the amount of nicotine in the flavoured juice. Off tobacco 6 years and vaping 5 years now. Question: Can you reverse the damage in the Aorta by quitting all.

What if you smoke cigars but you do not inhale?

Does this include nicotine tablets? My husband uses those to keep from smoking.

Never smoked, 6.1 A1c, psoriatic arthritis, and LDL of 107, 55 and had a stroke last week. Doctor wants me on Lipidtor. I don't want to take it, but I'm nervous about it. What should I do?

Before I lost weight I stopped smoking and switched to vaping. You are supposed to taper off. I haven't I actually went up in nicotine. I asked for help, and they said they don't know how to help people get off vaping. There is not enough research on how to quit. I thought the patch may help. Cold turkey would be worse than smoking.

So the other 4,000 chemicals in a cigarette aren't the source? Just the nicotine? What about foods with nicotine combined with there carbs?

What about the nicotine in the patches?

I recently had a discussion about vaping with someone who says that there has never been any studies that show that nicotine is bad for you. Can you share the studies that show this? This person is adamant that the studies don’t exist. They say that the studies are on cigarettes not nicotine itself. Thanks

What of nicotine patches?

Vaping is Definitely NOT worse than the chemical and tar filled cigarettes. I can breath when vaping and no high BP. Sorry, I recommend vaping to all smokers. It’s a life saver!!!!!!!!!

Is there a link to that 2015 study by Kelly Schweitzer ("Endothelial Disruptive Pro-Inflammatory Effects of Nicotine and E-cigarette Vapor Exposure") and her/his group, Doc? I don't see one in the show notes. I would love to give it a crack at reading your dissertation some day. Is there such a thing as purchasing a copy? I work on pianos and not humans, but I still love learning and I love a good challenge.

When I worked CICU I never saw a CEA on a non smoker.

Thank you 🙏! I think you are talking to people who have an income. Food like meat is almost impossible to get without money. Now with the lockdown here in France the homeless who get no benefits from the government or local social agencies cannot have the proper nutrition you propose on your videos. Your talk is very limited. In France we are only allowed to travel 1 kilometer from where we reside a 1 hour time limit to buy food or essentials. Those who do not abide are fined with no exceptions. This kind of stress kills ! If one is fined two times then the next time ( 3rd time) is prison! I am sure some homeless may die before the lockdown is over. Fasting is good but forced fasting is psychologically painful and lethal especially for those who have no comprehension or hope concerning this treatment provided his or her protecting government. Thank you again from my heart to yours Michael 🙏❤️🎶

What about a person who wears a nicotine patch or chews the gum, etc. Is it the drug itself or its delivery?

Is your PhD online accessible anywhere - I would to like reading it.

Can I ask is it true that taking olive oil can clear the fatty deposits in the arteries?

Doctor, does chewing tobacco have the same harmful effects?

Can you prove it???

How often should you have a CAC scan I had one about a year ago, my score was 0?

How about snus? I don’t see concrete evidence on it being for you. I have actually seen the opposite. This is a genuine question.

I do not inhale my premium cigars and the nicotine is fermented out for the most part....I plan on living as long as Milton Berle and George Burns

What about caffeine?

Dr Since i started Keto my blood sugar is regulated without needing Metamorfin, does that mean that I didn't have type two diabetes (highest 12 reading was 220) average was 120 and i never hit over 220 ever I used to take 1600mg worth of Metamorfin daily now I'm at zero and my blood sugar is at 90 almost throughout the day.

I would believe you any day.

Grr. Coming after my nicotine gum. Its all I had left lol.

What about THC? #Nice

DYSFUNCTIONAL EMOTIONAL SYSTEM USED NICOTINE in Cigarettes and Vaping

Thank you for addressing vaping!!! So much worse and gets far more people addicted to nicotine!

Regarding Vapping. Sound BS. It's much more safe than cigarettes. Please prove what you claim dear sir.

Oh, Lucifer, Bringer of the Light, and once God’s mightiest and most beloved - fallen! Don’t lose site of that pesky observation between messages and messengers having “less than optimal” outcomes, Doc - just ask Satan. I mean Lucifer. Meanwhile, thank you for the welcome elucidation.....Bill

I was the 100th like whoopee

💚

This is very misrepresentative of the medical literature on nicotine. I'm not advocating smoking or vaping, but this "doctor" quotes a single study and truly seems to have an axe to grind about people "abusing nicotine to regulate their emotional health". Nicotine's impact on endothelial cells has been studied fairly extensively, with very disparate results. Most studies show a dose-response curve with small amounts (microMole) being either innocuous or in same cases, actually beneficial to endothelial cell health. Traditional smoking only produces about a 1 microMole concentration in the blood stream; I doubt vaping would increase this by a factor of 1000, the amount necessary to reach 1 milliMole. However, even amounts from 1 mM (milliMole) to 2.5 mM have been found safe in multiple studies, and another study only detected damage to the endothelial cells at doses of 10 mM and above. On the other hand, nicotine is known to protect against pre-eclampsia by actually enhancing part of the endothelial cell backbone and new vascular growth in the developing embryo, and has definite neuroprotective effects against Parkinson's disease and some forms of dementia. It also prevents inflammation and bleeding of the gums in patients with acute bacterial gingivitis. This video is a largely science-free screed (one study from 2015 that is not presented in detail) against a substance that is still poorly understood. And the most ridiculous part is this "doctor's" rant about 19 year old Vietnam soldiers and coronary heart disease in post WW2 America. Has he examined the diets of these people? Of course not. Go look at the amount of candy bars and junk food, not to mention the bread, pastries, desserts, rice and pasta, eaten by the post-war generation and try to tease this out of the "doctor's" observational conclusions. Can't be done. Two thumbs down on this video.

Husband even sleeps with nicotine inside lip😫

I respect you , but here you are not using a science perspective . Put away your personal view .

Hujambo!
