I Quit a Strict Plant Based Diet – Doctor’s Perspective

Now as some of you may know, I’ve been doing
a primarily plant based or vegan diet for the last several years. But a few months ago, I decided to change that. [music] All right, so to fully understand the story we got to go a few years back. Just going back to high school and college,
I was always very interested in nutrition and living “optimally”, whatever that meant. And so, one of the things – I actually used
to be very turned off by vegans and then I became one which is kinda funny, because they
would like be shoving their beliefs down your throat right? So I’m at subway with my friend, it’s a very
illustrative example, and I think I’m being healthy at the time at least. I’ve got this you know, “whole wheat” bread
with turkey breast slices, so “white meat” and no cheese, no mayo. I’m like, “oh, I’m being so healthy”. My friend, he’s vegetarian, not quite vegan,
but he has cheese and mayo and white bread. I forget how the conversation proceed from
there, but – but I thought what I was eating was healthier and he thought what he was eating
healthier. In hindsight, both very unhealthy options,
because I had processed meat and the whole wheat bread is not whole wheat and – anyways. Now going into med school, again I’ve been
very you know like carnivore all the way but we had these student groups, and most med
schools have these student groups, you know, you have these lunch talks and to get students
to come versus just like studying on their own because everyone’s so busy in med school,
everyone’s so broke, they offer you these meals. So there’s free meals and you get like free
sandwiches, free Thai, free whatever, you get the food and then you of course sit down
and watch the lecture. And the talk at that time was from this retired
radiologist who was talking about a plant based diet. I said “OK, this actually pretty cool” because
he’s taking a very scientific approach and explaining why this is beneficial in a variety
of pathologies. Towards the end of the lecture, he brings
up Ulcerative Colitis which is a form of inflammatory bowel disease or IBD, and I have Crohn’s Colitis
and that really got my interest. So again, this is like back before I was open
about this. So after the lecture, I go up and I’m like,
“hey, can we talk more about this afterwards because I don’t want to – I don’t want people
to know I have IBD because it could really hurt my chances for residency”, at least,
for competitive residency. Anyways, we got to talking and you told me
all these stories about various patients he had either interacted with or his colleagues
had and how they were essentially cured from their IBD with a plant based diet. So I met one of these friends of his who had
Ulcerative Colitis and she had been on a plant based diet for a long period time and was
off it, all medications. That sounded pretty good, I said “hey, you
know what, What do I have to lose? I wanna be open minded, I wanna try things
out, I wanna self-experiment”. Of course I went to the literature, found
some studies that were supportive of the idea that a plant based diet was helpful for IBD. There was one main one, is this Japanese study,
not very – not a very strong study, but when you’re talking about something like nutrition
and another smaller subset like IBD, it’s really tough to find any good research. So the Tuesday before Thanksgiving, [laughs]
I decide I’m going plant based, I’m going to be vegan. And everyone I knew was like, “what is wrong
with you? Why right before Thanksgiving? Just wait until like, wait another week do
it after”. And for those who have watched my personality
type or my tendency type video on Med School Insiders, like this is a classic example of
a questioner. I said “why would I wait?” if I decided to
do it now, I’ll do it now. Who cares if Thanksgiving is in two days or
in a year. I mean, I’m kind of the same way about New
Year’s resolutions but that’s another discussion. So, I had great results pretty early on, within
a few months I had noticed that during my infusions cycles, so I get these – as you
guys have probably seen on Instagram, I get these infusions every eight weeks. And at the end, obviously the medication concentration
in your blood is going to drop and then you get a dose and over time that’s what you keep
– that’s why you have this eight week interval. Towards the end, the trough level was such
that I would be symptomatic. But when I was on this plant based diet, I
wasn’t symptomatic, this is awesome. So I was totally sold on the plant based diet
and I was sticking pretty strictly to that for the most part, for the last five years
since 2013, Thanksgiving of 2013. And I mean, you know, along the way, I started
adding a little bit of fish, fish maybe once every month or once every few weeks if that,
and that was also based on some of the literature that was describing, you know, these servings
of fish in moderation could actually help patients with IBD. So now you know why I did a plant based diet
and why I was convinced. But here’s the issue, the literature on nutrition,
it sucks. I mean, there’s no other way to say it. Part of that is because, look at what the
incentive is… if you don’t have companies that are going to benefit from you eating
a plant based or eating a ketogenic diet, then are you gonna have large well-funded
studies? Probably not, and that’s one of the issues
we face. The other thing right now with the nutrition
research is that, depending on what you want to believe, you can find evidence, you can
cherry pick the evidence for that. And the issue is that most of the evidence
for either the low carb or low fat diet groups is pretty flawed, and you can point out the
flaws in each study. Now, I’m not saying that I’m a nutrition expert
but I have done, like you guys can see my full list of publications, abstracts, presentations
on Kevinjubbal.com or on PubMed and you know, I have a foundation of what research entails,
what it is, the limitations of studies, the statistical analysis things like that, but
in no way am I saying that I’m a nutrition expert, absolutely not. In fact, I got kind of tired of reading the
primary literature myself, so what I do is I go to sources that I trust. These are doctors or scientists that read
the research themselves, synthesize it and give it to me in something that is quicker
and more effective, right? I don’t need to spend hours going through
all these papers myself and I recommend that you guys do that too. Because if you go to like these mainstream
news sources and read their articles that are totally sensationalized, these headlines,
just… it’s garbage. Don’t don’t read those, don’t base your decisions
off of that. Go to the real meat of it. Anyways, the two that I like is NutritionFacts.org
with Dr. Michael Greger and Peter Attia M.D., Dr. Attia. Dr. Attia is very low carb ketogenic and the
NutritionFacts is very plant based focused. So it’s really cool to see both of their opinions. And again, depending on what you want to believe,
you can cherry pick the evidence you want. Which brings me to the next point; self experimentation. Because the research in nutrition sucks, I
don’t find it reliable to just go off of that to make my own decisions. So for example, a few months ago, in early
2018 I started incorporating more meat into my diet. So there’s this one study on IBD, I saw this
actually on NutritionFacts.org where having up to two servings of meat per week do not
demonstrate any increased rates of flares or symptoms in patients with IBD. So, I figured I’ll try it out. Now, my philosophy on diet is, it’s less about
whether or not you’re having meat, whether or not you’re having a certain amount of carbs
or fats or whatever, what I think the key is, at least initially, those are more like
details you should worry about later, is the quality of your food, how much is processed. Now, a big issue I have with the current literature
in nutrition is you don’t see a high quality plant-based diet versus a high quality ketogenic
or low fat diet, right? You have like plant-based vs western diet,
like obviously this is gonna be better, right? Now, I’ve been doing this self experimentation
for the last several months and I’m tracking various markers like Faecal Calprotectin,
ESR, CRP, various blood tests to actually objectively quantify and track my inflammatory
bowel disease to see what works and what doesn’t work. A lot of companies reach out to me regularly
for sponsorships. And I turn down most of them. Like I’m getting several every week and as
you guys have noticed on the medical insiders and vlog channels, I usually don’t do sponsorships. Because I only want to promote things that
I actually believe are good for you guys, that you – that you would actually benefit
from. So this company, Butcherbox, reached out to
me a couple of weeks ago and I was like this is so funny, I’ve been doing – I’ve been eating
meat now for a couple months and now they reach out to me versus if they had reached
out to me like a year ago I would’ve been like absolutely not, I’m plant-based, right? So, I decided to check them out and there’s
actually two reasons why I wanna tell you about them; number one is, they had the subscription
box service right? So you get delivered high quality meats frozen
with dry ice straight to your door. As a busy pre-med or med student, that’s obviously
a huge time saver. But secondly and more importantly, it’s the
quality of their meats… or first of all, all their meats are hormone and antibiotic
free, you have free range chicken, the beef, so the cattle not only grass fed, but grass
finished. I didn’t actually know what the difference
was, but essentially to earn that grass fed label on packaging, the cows don’t need to
be grass fed for their entire life, only the beginning, only a certain amount of time. Grass fed and grass finished means that they
are fed grass throughout their life. And ultimately, you’re having these higher
quality sources of meat that I think is more important than whether or not you’re eating
meat in the first place. At least that’s my philosophy and my theory
right now. So if you guys do wanna check them out, they’re
doing a special offer with me. It’s butcherbox.com forward/medchoolinsiders,
you’ll get $20 off and I’ll place a link down in the description below as well. Anyway, that is it for this video, I’m about
to have dinner. Gonna have some Butcherbox meat and I’ll see
you guys in the next one. [music]

    Everyone, thank you for watching. The goal is to find the truth. I'm not bashing plant based diets, I was a strict plant based diet for a year, and on a very heavily focused plant based diet for another nearly 4 years. I am obviously very familiar with the research in order to make the shift for such a long period of time. As I stated in the video, I dove deep in the primary literature for a while, and recently I have resorted to nutritionfacts.org or Peter Attia for their summaries. It is important to note, there are significant flaws in the current nutritional research. Sounds like a great video opportunity for me to work on and explain 😉

    This is a great exercise in critical thinking and open mindedness – a factor I'm passionate about as I believe it is a foundational principle in success and living effectively. To those of you who welcome an intellectual discussion in search of the truth, I applaud you. You have a mindset that is not just inviting to others and noble, but effective. To those of you who were offended or triggered by the video, I invite you to consider that having a differing view point from another is not an attack on you. You're more likely to learn more and live a more fulfilling life by being open to having your own views challenged.

    Thanks for reading =)

    Hey great videos <3 i am not american but why being public about your diseas could habe an impact on getting into an „competitive“ residency?

    If you're a doctor you should know that our digestive system is too long to process meat properly. Compared to carnivores and omnivores, the meat stays in our intestines for too long and that causes it to kind of rot inside your body, which makes it release bad chemicals that can cause cancer, especially red meat.

    It's pretty upsetting that you recommend eating bacon, a Class 1A Carcinogen.

    Let's just ignore the carcinogenic Polycyclic Aromatic Hydrocarbons, the Heterocyclic Amines like PhiP, the N-Nitrosamines, the N-Glycolylneuraminic Acid and the fact that 100g of bacon cooked for 5 minutes has 91,577 iu of Carboxymethyllysine, the predominant Advanced Glycation End Product (dAGE), which is far more than equivalent portions of vegetables like carrots or corn, which have only about 7 to 10 iu per 100g. Not to mention the spike in IGF-1 and decrease in IGFBP-1 after eating such a meal and the fact that the AHA recommends limiting beef tallow, pig lard, butter and other primary sources of saturated fat to a minimum in the first place.

    I don't understand how a physician can look at the evidence and then choose to take the most extreme counterintuitive path, which is to recommend people to eat bacon from a butcher box.
    The science clearly supports NOT eating bacon and other processed or red meats.

    Mind boggling, really.

    “The literature on nutrition sucks “ really.What literature are you following when your colleagues prescribe fluoxetine,fucking up kids brain?

    I'm a person who has tried on a couple of different food ways over the years. And for me, what I've found to be a key is this. Don't eat for an ideology. Whatever it may be, Vegan, Keto, Carnivore, Plant Based, Jainism, whatever it is. Don't buy into the ideology of a diet. Because an ideology might sound good, but it may not be good for your particular body and health. For me, I was Vegan for like eight years. I had no idea that it was totally upsetting my hormones, esp my mental health due to the near complete lack of healthy fats. But because I had sold my soul to the Vegan ideology, I was convinced that it was my body/mind that was flawed and not the diet. But the reality is, Veganism is simply not the right diet for me. But the reason people don't want to hear that is because they've become an ideology driven person, a true believer in their diet's way, so they believe the diet is flawless and perfect and it's me (or whomever) that is the failed adherent. I hear this all the time from religious people and diet followers, "Oh, well you were never a real (Christian, Vegan etc.) you were doing it wrong, so your experiences don't count." This is nothing more than a neat trick to deflect criticism of their ideology and discrediting your lived experiences. Listen to your body, folks, it will tell you what's up when you look at the signs. Veganism might be fine for one person, Keto might be good for another. And they both may be total garbage to someone else. Don't get sucked into cult-think when it comes to diet or anything. Stay vigilant, think for yourself, listen to YOUR body. <3

    Regardless, if you are Vegan, Vegetarian, Keto, or whatever a good way to clean up your bodily health is to perform a good intestinal/colon cleanse in order to remove mucoid plaque. I know that most mainstream Gastroenterologists deny the existence of mucoid plaque but autopsies has confirmed its existence.

    This is what happens to supposedly "normal" people. You believe all the crap everyone tells you, find what you think "resonates" with you and dive in, boots and all, convinced that you have "been shown the light".
    In my time I had a condition that was dubbed a "grasshopper mind": I couldn't concentrate on any one subject for any length of time without becoming bored, so I would have up to ten books open, skipping between them whenever my mind started to fade. Today is has another name, for which: Adderall XR (dextroamphetamine/amphetamine extended release)
    Concerta (methylphenidate long acting)
    Daytrana (methylphenidate patch)
    Desoxyn (methamphetamine hydrochloride)
    Focalin (dexmethylphenidate)
    Focalin XR (dexmethylphenidate extended release)
    Metadate ER (methylphenidate extended release)
    Metadate CD (methylphenidate extended release)
    Methylin (methylphenidate oral solution and chewable tablets)
    Quillivant XR (methylphenidate extended release powder for oral suspension)
    Ritalin (methylphenidate)
    Ritalin SR (methylphenidate extended release)
    Ritalin LA (methylphenidate long acting)
    Strattera (atomoxetine)
    Vyvanse (lisdexamfetamine dimesylate) are prescribed to dumb the poor kids down and make them "more manageable".

    I didn't believe ANYONE! It appears that I was BORN a sceptic, so that when my parents warned me about how dangerous snakes are, I went to the library and read about them, only to discover that slightly more than eleven percent are actually dangerous and that only about five percent are deadly! Nobody goes haywire when the air is thick with mosquitoes or when they find ticks sucking their blood, even though they transfer some of the most devastating parasites to their hosts, but let a little snake show its head and even grown, brawny weight-lifter types lose what passes for their minds. I learned to identify the dangerous ones first, as the others were not of great concern.

    I dropped out of high school after scraping through Std 8 (Now Grade 10, I think) and soon left home and began the lifestyle of a wanderer. I remained in that state for nine years and boy! did I learn a lot, as I turned my hand to any job that was going in order to get money for food. I even cut lawns and tended gardens, helped to repair roofs and paint houses, for which all I asked in return was a meal or two. I served as barman and a chef in hotels; learned to weld and use tools as a boilermaker's assistant; spent a stint building a pipe organ in a church; piloted a boat that took people into the ocean to catch fish, learned carpentry and joinery; was a learner keeper in a zoological garden …

    I was no specialist in anything and THAT, to me, was a saving grace, as I have no firm convictions about anything.

    The only book I read that had any effect on me was the Atkins Diet Revolution: I needed to shed ten kilos and I did so within six weeks on this eating plan.

    I discovered that most research is not worth the paper it is written on and unless one uses oneself as the guinea pig and actually starts off with no preconceived ideas, but approaches it with an open-minded "I wonder what will happen if I do this?" question, one will always try to manipulate it to conform to one's prediction. This is why I do not trust the "scientific method".

    I have had the most astounding successes with every experiment I have tried so far – all in the medical field – and have reversed conditions that doctors have said were untreatable.

    I thus learned to "listen" to my body (I've lived in it for seventy years now and NO doctor can tell me that he/she knows it better than I do!) and have discovered that it does best on a carnivorous diet. After all, the only food substance to which nobody is congenitally allergic or sensitive is red meat. Did you know that? If not, then I have to ask why you tout yourself as a "doctor"? Unless it's a doctor of engineering or finance, so that it really doesn't count in this context, but as you follow your name with the letters "M.D.", I have to assume that you think you know something about medicine.To this end, I offer this quote by Sir William Oster, to a class of graduating med. students: " Gentlemen, I have a confession to make. Half of what we have taught you is in error, and furthermore we cannot tell you which half it is." Google his quotes and take note of them: he was a brilliant man.
    No two people are the same, so why the hell dieticians, nutritionists and the like think that there is a "one size fits all diet" beats merry hell out of me. The diet must be tailored to suit the individual – and ONLY the individual can discover it for him/herself.

    In the past I used to have a Mediterranean diet… and let me say it is the worst one can do. In the end I had lots of diseases (always hungry, headaches, intestinal dysbiosis, etc.). Then when I switched to a cyclical ketogenic Paleo diet everything went much better.

    My general rule is: meat, fish, eggs, vegetables, and little fruits.

    I no longer eat bread, pasta, pizza, white potatoes (I do eat some sweet potatoes) corn, legumes, cereal or grains.
