Latest / Hardiness with Dr Paul Taylor / Why your LDL cholesterol is not the best predictor of heart disease risk - and what is!
Transcript
- 0:09Speaker 1: Hey, everybody, Welcome to another edition of the podcast. And
- 0:12Speaker 1: this is a podcast that is about to change its name.
- 0:16Speaker 1: So in the next couple of weeks, I am going
- 0:18Speaker 1: to change the name of the podcast from the Paul
- 0:20Speaker 1: Taylor Podcast to the Hardiness Lab Podcast. And that reflects
- 0:25Speaker 1: a couple of things. Firstly, I have started a lab
- 0:29Speaker 1: with my old mate, so you'll be pretty familiar with
- 0:32Speaker 1: Professor Grant Schofield, and in that lab we are going
- 0:36Speaker 1: to be conducting research looking at the beneficial effects of hardiness,
- 0:42Speaker 1: both physical and psychological hardiness. The second reason for the
- 0:47Speaker 1: change the podcast is my new book, The Hardiness Effect,
- 0:51Speaker 1: is now out for pre order on Amazon, and that
- 0:55Speaker 1: really is reflecting all the stuff that we're doing in
- 0:58Speaker 1: the lab. And in that book, I go into all
- 1:01Speaker 1: of the research on psychological hardiness and how this is
- 1:05Speaker 1: the one psychological trait that you need in your life,
- 1:09Speaker 1: way above resilience, and also physiological hardiness, which people don't
- 1:15Speaker 1: really talk about, but me and Grant are going to
- 1:17Speaker 1: be exploring. So there we have it. Then we're going
- 1:19Speaker 1: to have a name change, and then if you like
- 1:22Speaker 1: my first book, Death by Comfort, jump onto Amazon and
- 1:25Speaker 1: you can pre order ny the hardiness Effect by doctor
- 1:30Speaker 1: Paul Taylor. Now let's get on with the podcast, and
- 1:35Speaker 1: today's show is a little bit of a hybrid. It
- 1:38Speaker 1: is a Saturday show, which is normally an interview, but
- 1:41Speaker 1: it's going to take the form of a kind of
- 1:44Speaker 1: extended Wisdom Wednesday podcast. And this is because I had
- 1:50Speaker 1: a couple of listeners actually reach out to me, and
- 1:53Speaker 1: a couple of conversations with friends that kind of all
- 1:57Speaker 1: around the same topic around cardiovascular disease. And I think
- 2:04Speaker 1: maybe the driver of those conversations was obviously me having
- 2:07Speaker 1: my open heart surgery, but talking about assessing your risk
- 2:12Speaker 1: for cardiovascular disease and the whole talk about LDL cholesterol.
- 2:18Speaker 1: So I thought this is worth a deep dive, and
- 2:22Speaker 1: what I'm going to talk about is probably going to
- 2:25Speaker 1: blow your mind. And we're going to talk about the
- 2:28Speaker 1: limitations of LDL cholesterol, why it's there as a marker,
- 2:33Speaker 1: but also a simple blood marker that predicts your risk
- 2:37Speaker 1: of dying from a heart attack between three to five
- 2:40Speaker 1: times better than your LDL cholesterol, which is the number
- 2:44Speaker 1: that your doctor tends to obsess about. And here's the kicker.
- 2:49Speaker 1: It's been hiding in plane sight on your standard blood
- 2:53Speaker 1: work this entire time, and as well as being a
- 2:59Speaker 1: very strong per day of your risk of cardiovascular disease
- 3:02Speaker 1: and dying from a heart attack, it also is a
- 3:05Speaker 1: strong predictor of your risk of metabolic disease, particularly type
- 3:09Speaker 1: two diabetes. And if you take those two together, cardiovascular
- 3:14Speaker 1: diseases and type and metabolic diseases, and they account for
- 3:19Speaker 1: a wobbing proportion of ill health and early deaths. So
- 3:25Speaker 1: actually getting on top of the two of them with
- 3:27Speaker 1: one blood marker, I think is really key. So let's
- 3:31Speaker 1: start with a question. It's going to make it. Think
- 3:35Speaker 1: how many of you being to the doctor, got your
- 3:37Speaker 1: cholesterol checked and walked out thinking that you knew everything
- 3:40Speaker 1: about your heart health because your LDL you're bad cholesterol
- 3:44Speaker 1: and inverticomas was in the normal range. Well, I hate
- 3:47Speaker 1: to break it to you, but you've been focusing on
- 3:49Speaker 1: their own number, and we're going to dive into the
- 3:52Speaker 1: cold heart science about that. So let's first paint the picture.
- 3:56Speaker 1: For decades, and I mean decades, the medical ist bablishment
- 4:00Speaker 1: has been layers are focused on LDL cholesterol as if
- 4:04Speaker 1: it's the holy grail of heart health, and they've built
- 4:08Speaker 1: entire treatment protocols around it, billions of dollars in stating prescriptions,
- 4:13Speaker 1: countless dietary recommendations, all centered around this one number. But
- 4:19Speaker 1: here's what they don't tell you. Half of people with
- 4:22Speaker 1: high cholesterol never have a heart attack, and half of
- 4:25Speaker 1: people who die from heart attacks do not have high cholesterol,
- 4:29Speaker 1: particularly they have normal LDL cholesterol. And this is such
- 4:34Speaker 1: a big predictor. Why is it that half of people
- 4:38Speaker 1: who die from heart attacks don't have what they think
- 4:42Speaker 1: is the best predictor? Just think about that for a second.
- 4:46Speaker 1: This is like flipping a coin. If half the people
- 4:48Speaker 1: with high cholesterol never have a heart attack and half
- 4:50Speaker 1: the people who die from heart attacks don't even have
- 4:52Speaker 1: high cholesterol, this is a coin flip. Now, don't get
- 4:56Speaker 1: me wrong. LDL cholesterol is not completely useless. The research
- 5:01Speaker 1: is clear that it is associated with cardiovascular events. Right,
- 5:05Speaker 1: So we're going to dig into the research here, so
- 5:08Speaker 1: strap yourself in. So there's a massive meta analysis of
- 5:11Speaker 1: sixty randomized control trials that showed for every one millimoll
- 5:17Speaker 1: per liter reduction in LDL cholesterol, and you get about
- 5:21Speaker 1: a twenty two percent reduction in major vascular events, right,
- 5:26Speaker 1: which seems to be pretty compelling. But here's where it
- 5:28Speaker 1: gets interesting, and this is from a study published in
- 5:31Speaker 1: the Journal of the American Heart Association that looked at
- 5:34Speaker 1: over fourteen thousand adults for more than twenty years. They
- 5:38Speaker 1: found something that isn't really talked about very much, very
- 5:42Speaker 1: low LDL levels below seventy mailograms per deci leader, which
- 5:49Speaker 1: translates to about one point eight one milli moles per lider.
- 5:55Speaker 1: Now it's a little bit confusing. I realized I just
- 5:57Speaker 1: need to explain this. This is like the US use
- 6:02Speaker 1: milligrams per deesto leader, some places like Australia in the
- 6:05Speaker 1: UK use millimoles per leader. In order to convert milligrams
- 6:10Speaker 1: per dest leader to millimals per leader, you divide by
- 6:13Speaker 1: thirty eight point sixty seven. You can just look for
- 6:16Speaker 1: a cholesterol ratio. Now I may use these two terms
- 6:18Speaker 1: interchangeably based on the different research where that research has
- 6:22Speaker 1: been conducted. But basically to say, to get back to
- 6:26Speaker 1: this very low levels of cholesterol the type that they
- 6:30Speaker 1: often want you to get down to, so below seventy
- 6:34Speaker 1: milligrams per deest leader are below one point eight one
- 6:38Speaker 1: milli moles per liter. And what they actually found was
- 6:43Speaker 1: it was associated with increased mortality, a forty five percent
- 6:49Speaker 1: higher risk of all cause mortality to be exact. Now,
- 6:53Speaker 1: that is absolutely massive, a forty five percent increased risk
- 6:59Speaker 1: of death from any cause. That is something that you
- 7:02Speaker 1: need to sit up and take notice about. So whilst
- 7:06Speaker 1: lower LDL cholesterol you seem to get a reduction in
- 7:09Speaker 1: major vascular events, you can't go too low and then
- 7:14Speaker 1: with very high levels, so above one hundred and ninety
- 7:20Speaker 1: milligrams per desi liter, which equates to an LDL level
- 7:26Speaker 1: of four point nine millimles per liter, So that that
- 7:29Speaker 1: is pretty bloody high, and that was bad too in
- 7:34Speaker 1: terms of risk for all cause mortality. But the point
- 7:37Speaker 1: is LDL cholesterol seems to have this weird u ship
- 7:42Speaker 1: relationship with death that nobody wants to talk about, in
- 7:45Speaker 1: that high levels are clearly not good, but low levels
- 7:49Speaker 1: are clearly not good as well. Let's now talk about
- 7:54Speaker 1: the game changer, and this has been as I said,
- 7:56Speaker 1: hiding and playin insight on your blood tests, and that
- 7:59Speaker 1: is your try glyceride to hit DL ratio. So triglycerides
- 8:04Speaker 1: are basically a measure of the excess fat that is
- 8:09Speaker 1: running around your bloodstream and it's often because we're just
- 8:12Speaker 1: eating excess energy, particularly excess carbohydrates. Hats DL, you may remember,
- 8:18Speaker 1: is the good cholesterol in inverted commas. So let's talk
- 8:22Speaker 1: about this number that is a game changer, and that's
- 8:26Speaker 1: the triglyceride to hits the L ratio. Now, that isn't
- 8:29Speaker 1: an obscure, expensive test, and this is something that is
- 8:33Speaker 1: standard on every single lipid panel that you've ever gotten.
- 8:38Speaker 1: And what you do is your triglycerides are divided by
- 8:42Speaker 1: your HITS d L cholesterol and you get a number
- 8:45Speaker 1: and that's it. And here's the bombshell, the Framingham Massive
- 8:49Speaker 1: Framingham research study, so that this ratio can be three
- 8:53Speaker 1: to five times more predictive than a heart attack risk
- 8:57Speaker 1: than LDL cholesterol. About that. Now, let me walk you
- 9:02Speaker 1: through some of the research that is really going to
- 9:06Speaker 1: get you to think about this stuff. Right. So, a
- 9:08Speaker 1: systematic review and meta analysis published just a few years
- 9:12Speaker 1: ago looked at thirteen cohort studies with over two hundred
- 9:17Speaker 1: and seven thousand participants in total, and what they found
- 9:20Speaker 1: was pretty stunning. People with the highest triglyceride to hit
- 9:24Speaker 1: stale ratios had a forty three percent higher risk of
- 9:27Speaker 1: cardiovascar events compared to those with the lowest ratios. But wait,
- 9:32Speaker 1: it gets more interesting in the Cooper Center Longitudinal study.
- 9:37Speaker 1: And in this they were following about forty thousand men
- 9:41Speaker 1: for over half a million person years. So what they
- 9:45Speaker 1: do is they obviously get the forty thousand and they
- 9:47Speaker 1: were following them for over ten years each, twelve twelve
- 9:52Speaker 1: and a bit years each, and they tried glysride to
- 9:55Speaker 1: heat Sdale ratio predicted Carnelie heart disease, cardiovasc disease, and
- 10:01Speaker 1: all cause mortality even after adjusting for all the traditional
- 10:07Speaker 1: risk factors, which included LDL cholesterol. And here's my favorite,
- 10:12Speaker 1: probably to pick up a bunch. And this study looked
- 10:15Speaker 1: at women with suspected heart problems and something that's called
- 10:19Speaker 1: the Women's Ischemia Syndrome evaluation. You can look that up.
- 10:24Speaker 1: And the triglys stride to hit the L ratio was
- 10:27Speaker 1: such a powerful predictor that women in the highest quartile,
- 10:31Speaker 1: so the highest twenty five percent, had a hazard radio
- 10:35Speaker 1: ratio of one point nine to five for death by
- 10:39Speaker 1: all causes. That means they were almost twice as likely
- 10:43Speaker 1: to die compared to the women in the lowest twenty
- 10:47Speaker 1: five percent for the draglystride to hit SDL ratio. So
- 10:50Speaker 1: to be clear on this, what you want to have
- 10:53Speaker 1: is low traglyst rides and high levels of hithdl. So
- 10:58Speaker 1: why is this ratio better than ldale cholesterol? I think
- 11:02Speaker 1: it's useful to really dig into it. So ldale cholesterol
- 11:07Speaker 1: is like looking at one picture of a very very
- 11:11Speaker 1: complicated puzzle. And LDAL cholesterol they don't actually measure directly.
- 11:17Speaker 1: It's done through a formula, which and I don't want
- 11:21Speaker 1: to dig into it because it just gets a bit
- 11:23Speaker 1: mind blowing. But the formula actually predicts your LDL cholesterol
- 11:28Speaker 1: and sometimes it's not tremendously accurate. Right, But let's talk
- 11:34Speaker 1: about trigger started to hit stale ratio firstly, and this
- 11:39Speaker 1: is really really important. It is a marker of insulin resistance. Right.
- 11:44Speaker 1: And you may have heard people like Peter Atia, doctor
- 11:47Speaker 1: Peter Atia talk about the four horsemen of chronic disease.
- 11:53Speaker 1: These are the four big buckets of chronic disease, and
- 11:58Speaker 1: they are cardiovascular disease also also metabolic diseases such as diabetes,
- 12:06Speaker 1: chronic kidney disease. These sorts of things that tend to
- 12:09Speaker 1: be lumped in together. We also have neurodegenerative diseases, and
- 12:13Speaker 1: then we have all the cancers. So if you put
- 12:15Speaker 1: them together, they're called the four horsemen of the apocalypse. Right,
- 12:19Speaker 1: and what your hites DL, tri grad trig sorry truglist
- 12:22Speaker 1: right hates DL ratio does. We've already established that it's
- 12:25Speaker 1: a very important predictor more important than ALDL of cardiovascular diseases,
- 12:31Speaker 1: but it is also the best predictor of metabolic diseases.
- 12:36Speaker 1: And that's because it's a marker of insulin resistance. When
- 12:39Speaker 1: your drag list rides are high, remember that's the fat
- 12:43Speaker 1: that's running through your bloodstream, and your HDL is low,
- 12:47Speaker 1: it is a sign that your body is struggling to
- 12:49Speaker 1: process glucose and fat properly. This creates a metabolic environment that,
- 12:56Speaker 1: as well as destroying your metabolism, is rocket fu for
- 13:00Speaker 1: heart disease. Secondly, this predicts the type of LDL particles
- 13:07Speaker 1: that you actually have, right, and we need to have
- 13:11Speaker 1: a little diversion on this. So your LDL that gets measured,
- 13:15Speaker 1: the number that you get from your doctor is the
- 13:18Speaker 1: total of all of your LDL particles. But those LDL
- 13:22Speaker 1: particles come in different sizes. Some are what we generally
- 13:27Speaker 1: refer to we put them in a bucket as big
- 13:29Speaker 1: fluffy LDL, and the other ones are small dense LDL. Now,
- 13:35Speaker 1: what we know from the research is that the small
- 13:39Speaker 1: dense LDL are the ones that are dangerous. They are
- 13:44Speaker 1: the ones that are athrogenic. It's those small dense LDL
- 13:49Speaker 1: that are the ones that get involved with the plaque
- 13:52Speaker 1: in your arteries. The big fluffy LDL are not pathogenic
- 13:58Speaker 1: at all. And what we know is your LDL test
- 14:03Speaker 1: that you get from your doctor tails you nothing about it.
- 14:06Speaker 1: So I'll give you a personal example. I've known for
- 14:09Speaker 1: years that my LDL cholesterol is reasonably high, but my
- 14:14Speaker 1: HATHDL cholesterol is also super high right now. I when
- 14:19Speaker 1: I saw my doctor years ago, it was talking about
- 14:22Speaker 1: the risk, but I kind of knew the research, and
- 14:23Speaker 1: I went and I actually had to pay to go
- 14:26Speaker 1: to a different lab and paid to get a whole
- 14:30Speaker 1: cholesterol panel which looks at the size of the LDL particles.
- 14:36Speaker 1: And you can get these from many different labs if
- 14:39Speaker 1: you work with a functional medicine doctor and they can
- 14:42Speaker 1: order you for them for them. Naturopaths can also order
- 14:46Speaker 1: them registered nutritious like me, you can also order them.
- 14:50Speaker 1: And what I found was that all of my LDL
- 14:54Speaker 1: is big fluffy LDL and very little of it was
- 14:59Speaker 1: small dense LDL. And then I know that my my
- 15:03Speaker 1: trag glytrides are very low and my hits d L
- 15:06Speaker 1: is very high, So that actually gives me a really
- 15:10Speaker 1: good profile in terms of cholesterol. And I've also looked
- 15:13Speaker 1: at something called apo B which is really interesting as
- 15:16Speaker 1: well as a little A but we're not we're not
- 15:19Speaker 1: going to dive into that because it gets a bit
- 15:21Speaker 1: more complicated. Let's just come back to this. So the
- 15:25Speaker 1: track glytride hits the L ratio as well as being
- 15:28Speaker 1: a marker of insulin resistance and your risk of developing
- 15:31Speaker 1: type two diabetes, chronic kidney disease, all those sorts of things, obesity,
- 15:35Speaker 1: and it also and it predicts that you will have
- 15:41Speaker 1: more small dense LDL. So the higher that ratio is,
- 15:45Speaker 1: the more likely you are to have small dense LDL particles,
- 15:50Speaker 1: the really nasty ones that burrow into your audio walls
- 15:53Speaker 1: like tiny bullets. Now, when this ratio is low, you
- 15:58Speaker 1: will have large, fluffy l L particles that are relatively harmless,
- 16:02Speaker 1: and that's exactly what mine showed when I tested both
- 16:05Speaker 1: of them. Now, thirdly, and this is crucial, the triglyceride
- 16:09Speaker 1: to Hitsdale ratio capture something called residual risk. This is
- 16:15Speaker 1: the cardiovascular risk that persists even when your LDL cholesterol
- 16:22Speaker 1: is perfectly controlled with statins. So we know from the
- 16:26Speaker 1: research on statins statins can be useful in preventing death,
- 16:31Speaker 1: but only the research shows only in people who have
- 16:35Speaker 1: had a carnary event or have existing carnary artery disease.
- 16:41Speaker 1: The other research shows that statins in other populations actually
- 16:45Speaker 1: does not reduce deaths from cardiovascular diseases. Now, let's get
- 16:50Speaker 1: back to this triglystid hits The ratio I study published
- 16:54Speaker 1: in the Frontiers in Cardiovascular Medicine looked at diabetic patients
- 16:58Speaker 1: with carnery ardy disease who were already on statins, and
- 17:02Speaker 1: guess what, The triglyceride to hats Dale ratio was still
- 17:06Speaker 1: a powerful predictor of death and cardiovascular events even in
- 17:12Speaker 1: those people with LDL cholesterol that was well controlled by statins.
- 17:17Speaker 1: So this is what we call residual risks. So let's
- 17:21Speaker 1: get practical. What should your triglyceride to hates DL ratio B. Well,
- 17:29Speaker 1: of course this answer is not straightforward because it depends
- 17:33Speaker 1: where you're actually from or what units that you use
- 17:36Speaker 1: to be more accurate, right, because the conversions are different
- 17:42Speaker 1: for triglycerides and for hits DL. So basically, if you
- 17:47Speaker 1: use US standard units, so if you live in the
- 17:50Speaker 1: United States or you're using those units, if your number
- 17:54Speaker 1: is in milligrams per desi liter, then the recommended ratios
- 17:59Speaker 1: are less than three. Well, what we know is that
- 18:02Speaker 1: above three that is where you really get into trouble.
- 18:07Speaker 1: Anything above three in men and above two in women
- 18:11Speaker 1: put you in the danger zone. Right, that's if you
- 18:15Speaker 1: use milligrams per deesta leader, if you use millimos per leter,
- 18:20Speaker 1: anything above one point three per man So if you
- 18:23Speaker 1: live in Australia, UK, those sorts of places, anything above
- 18:26Speaker 1: one point three of that ratio. So if your triglystrides
- 18:29Speaker 1: are one in a third times you hate the ler more,
- 18:32Speaker 1: then you're in trouble. And women anything above zero point nine, right,
- 18:36Speaker 1: then you're in trouble. Now, what is optimal in the US, right,
- 18:42Speaker 1: the milligram per destileter ideally for optimal for both men
- 18:47Speaker 1: and women. Here it should be less than one, so
- 18:49Speaker 1: your HDL should be higher than your triglystrides. Right. For
- 18:53Speaker 1: the international standard the people who use millimals per leader,
- 18:57Speaker 1: like in Australia, it should be less than zero point four, right,
- 19:01Speaker 1: so your Hatesdale should be more than double your triglycerides. So,
- 19:07Speaker 1: just to clear up any confusion, the reason why those
- 19:10Speaker 1: ratios are different is that the conversion formula for triglycerides
- 19:16Speaker 1: between American and miligrams for deest leader and minimals per
- 19:20Speaker 1: leader is different to the conversion formula for Hatessdale cholesterol.
- 19:24Speaker 1: So that's why there's a discrepancy in the ratio for
- 19:26Speaker 1: any of those. They have a bit of maths and things,
- 19:28Speaker 1: and this is a bit weird. Anyway, back to the
- 19:31Speaker 1: story here, and some other interesting research has come out
- 19:36Speaker 1: that this ratio, that the trigrisside Hatesdale ratio, is even
- 19:42Speaker 1: more powerful as a predictor for women. A study published
- 19:46Speaker 1: in the Journaly of the American Heart Association looked at
- 19:49Speaker 1: women with non obstructive carn reority disease. These are the
- 19:53Speaker 1: women who have chest pain and heart problems but don't
- 19:55Speaker 1: have the classic blocked arteries you see in men. The
- 19:59Speaker 1: triglyceride dale ratio was a powerful independent predictor of major
- 20:05Speaker 1: adverse cardio vascular events in these women. And here's the kicker.
- 20:09Speaker 1: In some populations, this ratio predicts cardiovascular risk in women,
- 20:15Speaker 1: while the traditional LDLD hates dale ratio doesn't predict anything
- 20:20Speaker 1: at all. This makes sense when you think about it.
- 20:23Speaker 1: Women's heart disease often looks different from men's. They're more
- 20:27Speaker 1: likely to have microvascular dysfunction and metabolic abnormalities, and the
- 20:33Speaker 1: triglyceride hates stale ratio captures that beautifully. Now you might
- 20:38Speaker 1: be wondering, if this research is so compelling, why is
- 20:42Speaker 1: my doctor talking about this? Why isn't this the major
- 20:46Speaker 1: focus when I go to get my blood tests? And
- 20:49Speaker 1: it's a great question. The answer is probably a little
- 20:51Speaker 1: bit frustrating. And firstly, medical education moves at the speed
- 20:57Speaker 1: of molasses. It's well known that it takes seven to
- 21:02Speaker 1: ten years to get from research into medical education, and
- 21:07Speaker 1: the research I'm sharing with you is relatively recent now. Second,
- 21:11Speaker 1: the medical system has been built for decades around treating
- 21:16Speaker 1: LDL cholesterol. We have drugs at lower LDL, we have
- 21:20Speaker 1: guidelines based on LDL and try treatment algorithms are LDL centric.
- 21:26Speaker 1: Changing that system is like trying to turn a friggin
- 21:30Speaker 1: oil tanker. Now. Third, and this is where you can
- 21:34Speaker 1: be a bit more cynical. There's a shitload of money
- 21:37Speaker 1: in the current system. Starting prescriptions are multi billion dollar
- 21:41Speaker 1: industries and studies are often funded by this. And I'm
- 21:45Speaker 1: not a conspiracy theorist, but when there are finance strong
- 21:49Speaker 1: financial interests, you do have to question stuff. And this
- 21:53Speaker 1: entire cholesterol industrial complex is built around LDL cholesterol. But
- 21:59Speaker 1: here's what's encouraging some forward thinking doctors really focus on this,
- 22:04Speaker 1: particularly if you have a functional medicine doctor, because the
- 22:09Speaker 1: research really is too compelling to ignore, or if you've
- 22:12Speaker 1: got a doctor who has the time to actually dig
- 22:15Speaker 1: into the research. So let's talk about the metabolic connection,
- 22:19Speaker 1: because this is huguely important. It's not like cardiovascular disease
- 22:22Speaker 1: is completely independent from metabolic disease. There is a very
- 22:27Speaker 1: strong overlap. You know, we are a complex ecosystem, So
- 22:31Speaker 1: when your triglycerides are high, it usually means one of
- 22:35Speaker 1: two things. Either you're eating too many refined carbohydrates and sugars,
- 22:40Speaker 1: or your body has become insulin resistant and can't properly
- 22:45Speaker 1: clear fat from your bloodstream. So, just to add a
- 22:49Speaker 1: little bit of color on that Althow, triglycerides are a
- 22:53Speaker 1: fat in the bloodstream. It's basically driven by refined carbohydrates
- 22:58Speaker 1: and sugars that I actually create those triglycerites, right, So triglycerites,
- 23:03Speaker 1: even though it's a fat, doesn't mean you're eating too
- 23:05Speaker 1: much fat. It's generally too much refined carbohydrates and sugars,
- 23:09Speaker 1: or just too much carbohydrates for your tolerance level, because
- 23:13Speaker 1: we can all tolerate different levels. Now, switching over to HATESDL.
- 23:17Speaker 1: When your hatesdale is low, that means that your body's
- 23:21Speaker 1: natural clean up crew, the particles that pull cholesterol out
- 23:26Speaker 1: of your artery walls and transport it back to your
- 23:29Speaker 1: liver for disposal, it's understaffed essentially. Now, when you put
- 23:34Speaker 1: these two together, you got the perfect storm. More athrogenic
- 23:39Speaker 1: particles in your blood, less clean up activity, and an
- 23:43Speaker 1: underlying metabolic dysfunction that creates inflammation and oxidative stress. And
- 23:50Speaker 1: a study published in Scientific Reports followed three hundred and
- 23:54Speaker 1: fifty five patients with stable angina for over four years,
- 23:59Speaker 1: and they find that patients in the highest quartile, the
- 24:02Speaker 1: highst twenty five percent of the tiger side hat stale
- 24:06Speaker 1: ratio had nearly three times the risk of death or
- 24:10Speaker 1: heart attack compared to those in the lowest quartile. And
- 24:14Speaker 1: this was independent of their LDL cholesterol levels, right, And
- 24:19Speaker 1: you don't get anything like that when it comes to
- 24:22Speaker 1: LDL cholesterol. You don't get three times the risk of
- 24:27Speaker 1: death or heart attack with people with high LDL compared
- 24:29Speaker 1: to those with low LDL. And that's how I talk
- 24:32Speaker 1: about the Cooper Institute, which is a really, really good
- 24:37Speaker 1: research institute. Now they've been studying health and fitness for decades,
- 24:43Speaker 1: and they looked at the relationship between cardio respiratory fitness,
- 24:47Speaker 1: which you've heard me talk about this BO two max
- 24:49Speaker 1: the single biggest predictive of how long you're going to live.
- 24:52Speaker 1: They looked at a relationship between that your trigglysarid hayte
- 24:55Speaker 1: stale ratio and death from cornery heart disease in men,
- 24:59Speaker 1: and what they found was pretty remarkable. Even among the
- 25:02Speaker 1: men with the lowest healthiest triglist ride to hate stale ratios,
- 25:07Speaker 1: those who were physically unfit were more than twice as
- 25:11Speaker 1: likely to die from heart disease compared to those who
- 25:14Speaker 1: were highly fit. But here's the really interesting part. Across
- 25:18Speaker 1: all fitness levels, men with higher triglyst ride to hate
- 25:22Speaker 1: stale ratios had significantly higher death risks our death rates.
- 25:27Speaker 1: This ratio was independent predictor regardless of how fit you
- 25:32Speaker 1: you were, and this is key when it comes to research.
- 25:36Speaker 1: When you see it across different groups or subgroups of people,
- 25:42Speaker 1: then you start to go, hey, this evidence is becoming
- 25:45Speaker 1: pretty compelling and it tells us something crucial. Fitness matters enormously,
- 25:50Speaker 1: as I've said, but metabolic health as reflected by the
- 25:54Speaker 1: triglist right hates stale ratio is very very important as well,
- 25:58Speaker 1: and it interacts with your fitness. So let's talk about
- 26:02Speaker 1: how we can use this information practically. So first of all,
- 26:06Speaker 1: you need to calculate your ratio, all right. You take
- 26:08Speaker 1: your trig list ride number on your results blood results,
- 26:12Speaker 1: you divided by your head stale number, and both should
- 26:15Speaker 1: be from the same blood test and ideally at fasted
- 26:19Speaker 1: blood tests because they can be affected, particularly your trig
- 26:23Speaker 1: list rights. So let's remember back to the formulas. If
- 26:26Speaker 1: you use the US centric milligrams per desant leader. If
- 26:30Speaker 1: that's what it says on your test. If your ratio
- 26:33Speaker 1: is above three for men or two for women, you
- 26:37Speaker 1: have to take action. And that more above that it
- 26:41Speaker 1: is the quicker and the stronger the action that you
- 26:45Speaker 1: need to take. And then if you use minimals per Leter,
- 26:50Speaker 1: if it's above one point four for women or not
- 26:52Speaker 1: point nine, sorry one point four for men and not
- 26:55Speaker 1: point nine for women, then you gotta take action. But
- 26:59Speaker 1: the good new is that this ratio responds beautifully to
- 27:04Speaker 1: lifestyle interventions. Low carbohydrate diets have consistently been shown to
- 27:11Speaker 1: dramatically improve the triglyceride to hit stale ratio. A meta
- 27:15Speaker 1: analysis published in plus one plus one showed that low
- 27:19Speaker 1: carb diets consistently lower trigly rides and reis hate stale cholesterol,
- 27:25Speaker 1: and exercise is equally powerful. A regular aerobic exercise and
- 27:31Speaker 1: regular strength training increases hate stale cholesterol. Particularly strength training
- 27:36Speaker 1: and both types of exercise help your body become more
- 27:39Speaker 1: efficient at clearing triglycerides from your bloodstream. Intermittent fasting can
- 27:45Speaker 1: also be incredibly effective because it gives your body regular
- 27:49Speaker 1: breaks from insulentce spikes, allowing your trigly rides. To normalize. Right.
- 27:54Speaker 1: So how you use this practically is doing those sorts
- 27:59Speaker 1: of informat intermittent fasting, so you know, stop eating three
- 28:04Speaker 1: hours before you go to bed and in fast for
- 28:07Speaker 1: twelve to sixteen hours, right, and that is going to
- 28:11Speaker 1: really get your insulin under control. And then eating low
- 28:15Speaker 1: carbohydrate diets with good amounts of protein and good amounts
- 28:19Speaker 1: of fat will keep your inchinin levels under control. And
- 28:22Speaker 1: just managing your carbohydrates is really really key for this thing. Now,
- 28:28Speaker 1: one other thing that I have actually been playing with
- 28:31Speaker 1: to keep that level lower, to keep insulin, which is
- 28:36Speaker 1: as we said, is reflected with your tagles start hit
- 28:38Speaker 1: stale ratio is for your breakfast is to just change
- 28:43Speaker 1: what your breakfast looks like, to make sure that your
- 28:46Speaker 1: breakfast is a high protein, high fat, low car breakfast.
- 28:52Speaker 1: And that is really key because it's the carbohydrate that
- 28:56Speaker 1: gives us the big insulin spike. So certainly not the
- 29:01Speaker 1: breakfast that a lot of people eat of breakfast cereal
- 29:04Speaker 1: or toast and orange juice, those sorts of things they'll
- 29:06Speaker 1: play havoc with that. You want to be eating stuff
- 29:10Speaker 1: like an omelet without the toast, and those sorts of
- 29:13Speaker 1: things are any of those ketigenic are low car breakfasts
- 29:19Speaker 1: are absolutely the way to go, and that will keep
- 29:22Speaker 1: your insulin under control for more than half the day,
- 29:26Speaker 1: which is really really important. Now here's something else that's
- 29:30Speaker 1: interesting to come out of the research. Certain medications can
- 29:33Speaker 1: improve your triglists right to hit stale ratio, but not
- 29:37Speaker 1: always in a way that you'd expect. So statins, which
- 29:40Speaker 1: millions of people take, they're cholesterol lowering drugs. They can
- 29:44Speaker 1: improve that the triglists are to hit stale ratio by
- 29:47Speaker 1: about ten to twenty percent. They typically lower tracklist rides
- 29:52Speaker 1: by up to fifty percent in some people. However, some
- 29:57Speaker 1: people when they take statins, their risk of diabetes and
- 30:01Speaker 1: metabolic function dysfunction actually goes up. So you have to really,
- 30:06Speaker 1: if you're honest, that you've gotta look at this stuff.
- 30:09Speaker 1: But there is other things, or there are other things.
- 30:12Speaker 1: Fibrates niacin, which is a vinamin one of the B vinamins,
- 30:17Speaker 1: and a mega three fatty acids are often more effective
- 30:20Speaker 1: at improving this ratio than statins, and they don't have
- 30:23Speaker 1: the side effects. They specifically target triglys rides and they
- 30:27Speaker 1: can rease hate DL cholesterol as well. So they're working
- 30:29Speaker 1: on both sides of the equation, and that's why quite
- 30:33Speaker 1: a few progressive cardiologists are starting to look beyond just
- 30:36Speaker 1: prescribing statins and are also considering combination therapies that target
- 30:42Speaker 1: the entire lipid profile, not just LDL cholesterol. So let's
- 30:47Speaker 1: go back and and really reconnect the dots around diabetes,
- 30:53Speaker 1: because this triglys ride hates the L ratio also predicts diabetes.
- 30:58Speaker 1: The Cooper Center for Longitudinal study found that trieglist rate
- 31:02Speaker 1: hits stale ratio was a strong predictor of developing type
- 31:06Speaker 1: two diabetes in man, so it's an early warning that
- 31:11Speaker 1: you're on your way to diabetes. That makes perfect sense
- 31:14Speaker 1: because this ratio reflects in shilin resistance, which is the
- 31:17Speaker 1: underlying driver of type two diabetes. And anybody tells you otherwise,
- 31:20Speaker 1: it's completely and utterly bonkers. So if your triglistrid hit
- 31:25Speaker 1: stale ratio is elevated, you're not just at high risk
- 31:28Speaker 1: for heart disease, you're also at high risk for diabetes
- 31:31Speaker 1: and all of the other metabolic consequences of that. And
- 31:35Speaker 1: if you develop diabetes, your cardiovascular risk goes through the roof.
- 31:41Speaker 1: This is why this ratio is so powerful it's capturing
- 31:44Speaker 1: an underlying metabolic dysfunction that drives two of the four
- 31:51Speaker 1: horsemen of chronic disease. Now age also plays a role here.
- 32:00Speaker 1: A meta analysis of LDL cholesterol reduction studies, so these
- 32:03Speaker 1: were intervention studies, found that the relative benefit of lowering
- 32:08Speaker 1: LDL cholesterol appears to decrease with age, particularly in primary
- 32:14Speaker 1: prevention and starting and trying to prevent disease before it
- 32:17Speaker 1: actually happens. But you know what doesn't lose its predictive
- 32:20Speaker 1: part with age, the triglyst right to hit the L
- 32:23Speaker 1: ratio right. So some of the research that's coming out,
- 32:26Speaker 1: just to give a bit more on that, shows that
- 32:29Speaker 1: LDL cholesterol reduction can be protective in people in their thirties, forties, fifties,
- 32:36Speaker 1: but once they get into their sixties, it's a lot
- 32:39Speaker 1: less protective. But managing the triglyst right hates d L
- 32:43Speaker 1: ratio works across all of the age spans. And it
- 32:47Speaker 1: makes sense when you think about it, because as we age,
- 32:50Speaker 1: metabolic dysfunction becomes increasingly important as a driver for cardiovascular disease,
- 32:56Speaker 1: and the triglystrid hates the L ratio captures this metabolic
- 33:00Speaker 1: opponent that LDL cholesterol actually misses. Now, I want to
- 33:05Speaker 1: circle back to something that I mentioned earlier, and that's
- 33:09Speaker 1: about women's heart health and saying that this ratio is
- 33:12Speaker 1: particularly crucial, and that's because women's heart disease doesn't follow
- 33:16Speaker 1: the same pattern as men's heart disease. They're more likely
- 33:20Speaker 1: to have that microvascular dysfunction as I mentioned earlier, and
- 33:24Speaker 1: this is problems with tiny blood vessels in the heart
- 33:28Speaker 1: rather than blockages in the major arteries. Now, this type
- 33:31Speaker 1: of heart disease is closely linked to metabolic dysfunction, insulin resistance,
- 33:36Speaker 1: and inflammation, all the things that traglystrid hates stale ratio
- 33:40Speaker 1: captures beautifully. And the Women's Ischemia Syndrome Evaluation Study followed
- 33:47Speaker 1: over five hundred women for six years, and what they
- 33:50Speaker 1: found was that the traglystride hates stale ratio was a
- 33:53Speaker 1: powerful predictor, such a powerful predictor that it remains significant
- 33:59Speaker 1: even and after they adjusted for age, race, smoking, high
- 34:04Speaker 1: blood pressure, diabetes, and the results of their coronary and geograms.
- 34:09Speaker 1: So this is really really powerful and if you're a woman,
- 34:14Speaker 1: you really need to think about this. And if you
- 34:17Speaker 1: have chest pain, fatigue, or other symptoms, but your doctor
- 34:20Speaker 1: says your orderies look fine, ask them about your trackler
- 34:23Speaker 1: storry to hit stale ratio because that might be the secret,
- 34:26Speaker 1: little key to what is actually going on. Now, let's
- 34:31Speaker 1: talk about some other research. We are getting towards the
- 34:34Speaker 1: end of this. But scientists have started using advanced imaging
- 34:37Speaker 1: techniques to look not just at whether you have plaque
- 34:40Speaker 1: in your arteries, but what type of plaque that you have.
- 34:44Speaker 1: And actually I had this done on me because obviously
- 34:47Speaker 1: for my open heart surgery. Now, as my carreologist explained
- 34:51Speaker 1: to me, some plaques are stable, They're like concrete. Now
- 34:56Speaker 1: they might narrow your arteries, but they are not likely
- 35:00Speaker 1: to rupture and cause a heart attack. And these are
- 35:04Speaker 1: plaques that have calcium basically stabilizing them. Other plaques are vulnerable.
- 35:11Speaker 1: They're like volcanoes are wailing to erupt. And a study
- 35:15Speaker 1: published in the European Heart Journal use cornery ct angiograph
- 35:19Speaker 1: to identify high risk vulnerable plaques, so we can actually
- 35:23Speaker 1: look at this now. What they found was remarkable. Patients
- 35:26Speaker 1: with higher triglist right hate stale ratios were significantly more
- 35:30Speaker 1: likely to develop these dangerous, vulnerable plaques. And here's the
- 35:34Speaker 1: kicker that that ratio triglist right hate stale ratio was
- 35:38Speaker 1: an independent predictor of future cardiovascular events. With the hazard
- 35:42Speaker 1: ratio of one point ninety four. That means that people
- 35:45Speaker 1: with higher ratios were nearly twice as likely to have
- 35:47Speaker 1: a heart attack or a stroke, right, And this suggests
- 35:51Speaker 1: that this ratio doesn't just predict cardiovascular events, it actually
- 35:55Speaker 1: helps identify the people who have the most dangerous type
- 36:00Speaker 1: of plaque in their arteries, right, the unstable plaque, which
- 36:05Speaker 1: is key. And if you think about it, this makes
- 36:07Speaker 1: sense because hits dl can actually have a beneficial effect
- 36:13Speaker 1: on the plaque that you actually have. And then there's
- 36:16Speaker 1: the whole triglyceride thing. But another thing I wanted to
- 36:21Speaker 1: talk about is just to revisit again that residual risk idea.
- 36:26Speaker 1: So for decades it was thought that if you can
- 36:30Speaker 1: just get LDL cholesterol low enough, you're gonna limit most
- 36:33Speaker 1: cardiovascular risk. And a lot of people still think of it,
- 36:37Speaker 1: and it turns out that the evidence does not support it.
- 36:40Speaker 1: Even when LDL cholesterol is optimally controlled with statins, many
- 36:44Speaker 1: people still have heart attacks and structure. So they call
- 36:47Speaker 1: this residual risk, and it's a huge problem in cardiology.
- 36:51Speaker 1: Multiple studies have shown that the triglystraide hates the L
- 36:56Speaker 1: ratio captures this residual risk beautifully. That identifies people who
- 37:01Speaker 1: are still at high risk even when their LDS cholesterol
- 37:05Speaker 1: profile looks perfect on paper. And these people might be
- 37:09Speaker 1: thinking they're fine, but they can still be at risk.
- 37:12Speaker 1: And they're studying diabetic patients with carniordy disease who were
- 37:16Speaker 1: already on STATNS founded triglstraide hit stale ratio was still
- 37:20Speaker 1: a powerful predictor of death and cardiovascular events. And the
- 37:25Speaker 1: hazard ratio for the highest churchil the highest and thirty
- 37:28Speaker 1: three percent was one point seven to seven for all
- 37:32Speaker 1: cause mortality and one point five to two for cardiovascular death.
- 37:36Speaker 1: And that is massive, And this is why this ratio
- 37:40Speaker 1: is so clinically important. It helps identify the people who
- 37:44Speaker 1: need more aggressive intervention beyond just LDL lowering. So let's
- 37:50Speaker 1: not get practical after all of that. If your head
- 37:53Speaker 1: has stopped spinning, So first of all, it's get your
- 37:57Speaker 1: numbers right, and remember those numbers what they need to be.
- 38:02Speaker 1: If you're us centric, you need to have that number.
- 38:07Speaker 1: Ideally it's below one, right, so your heat stale is
- 38:11Speaker 1: higher than your triglys rides if you are and also
- 38:15Speaker 1: uk those sorts of things you use minimals per leader.
- 38:19Speaker 1: Ideally that's below zero point four that ratio, right, so
- 38:23Speaker 1: your heat stale should be more than double your triglyss rides. Right.
- 38:27Speaker 1: If it's not like that, here's your action plan. Firstly,
- 38:31Speaker 1: it's fix the diet. This this ratio responds incredibly well
- 38:37Speaker 1: to reducing refined carbohydrates and sugar, and even for some
- 38:42Speaker 1: people reducing complex carbohydrates because we all tolerate carbohydrates differently.
- 38:47Speaker 1: Every grammar sugar you potentially reaches your truglyst rights and
- 38:51Speaker 1: lowers your heat stale. And it's particularly ultra processed foods
- 38:54Speaker 1: are a real issue here. So I would highly recommend
- 38:59Speaker 1: going on a low diet if there's an issue with
- 39:01Speaker 1: that ratio. And then movement right. Regular exercise is one
- 39:06Speaker 1: of the most powerful ways to improve this ratio, and
- 39:09Speaker 1: a combination of cardiovascular stuff and strength training seems to
- 39:14Speaker 1: be the optimal. And then potentially consider intermittent fasting. Giving
- 39:19Speaker 1: your body regular breaks from food allows that trag list
- 39:23Speaker 1: ride and level to normalize and can improve your insulin sensitivity.
- 39:28Speaker 1: And if you don't want to do that fast, make
- 39:31Speaker 1: sure that your breakfast is a very low car breakfast
- 39:34Speaker 1: that has plenty of protein and fat that will give
- 39:37Speaker 1: you good satiety. You'll find you don't need the morning
- 39:40Speaker 1: snack anymore and that will control your inchin level and
- 39:44Speaker 1: your trig list ride to HAITSTL. And the other thing
- 39:47Speaker 1: is sleep. Sleep breaks havoc on your metabolic health and
- 39:50Speaker 1: can worsen that ratio. So having all the good sleep
- 39:54Speaker 1: pagen that I've talked before, and then managing stress. Stress
- 39:58Speaker 1: elevates cortisol and it cordisol has been known to drive
- 40:03Speaker 1: insulin resistance and negatively impact that profile. The last thing
- 40:08Speaker 1: that I would say is triglyrites and HDL. They are
- 40:12Speaker 1: two components of the metabolic syndrome. And we know that
- 40:16Speaker 1: if you have metabolic syndrome, your risk for lots of
- 40:21Speaker 1: different chronic diseases actually goes through the roof. So metabolic
- 40:25Speaker 1: syndrome is defined. It's a cluster of conditions to do
- 40:29Speaker 1: with metabolism, and different organizations will identify it differently. Most
- 40:35Speaker 1: of them say three from five of these things. High
- 40:39Speaker 1: blood pressure, high triglycerides low HDL right, so that traglystrid
- 40:45Speaker 1: hates stale ratios in there, central obesity, which is a
- 40:49Speaker 1: lot of fat around the middle right. And the last
- 40:54Speaker 1: thing is high fasting blood glucose, and that is often
- 40:58Speaker 1: the last thing to go is your blood glucose. So
- 41:02Speaker 1: a lot of people just look at the blood and
- 41:04Speaker 1: go I'm fine, when actually you're not. You could have
- 41:07Speaker 1: the metabolic syndrome even if you have normal blood glucose.
- 41:12Speaker 1: So I would just throw that one out there because
- 41:15Speaker 1: I think the metabolic syndrome has been massively or has
- 41:20Speaker 1: not been focused on anywhere near enough when it comes
- 41:24Speaker 1: to our long term health. So the take home for
- 41:26Speaker 1: me is to not make decisions on drug therapy based
- 41:31Speaker 1: on LDL alone. Use that ratio. That ratio is really
- 41:36Speaker 1: powerful at trigg list right that hits the L ratio.
- 41:39Speaker 1: If you want to be more comprehensive, you can order
- 41:42Speaker 1: through a number of different health professionals. You can go
- 41:45Speaker 1: and get an entire LDL panel looking at your particle size.
- 41:50Speaker 1: You can also measure your APO B, which is much
- 41:55Speaker 1: more important than L d L and your APO B
- 41:57Speaker 1: to APO a ratio. But if you don't want to
- 42:01Speaker 1: go and spend all that money just making sure that
- 42:04Speaker 1: you control your tragglyst ride to hates the l ratios,
- 42:07Speaker 1: drive down those tragg list rides, drive up those hat
- 42:09Speaker 1: d ls. That really is one of the keys to
- 42:13Speaker 1: metabolic health. That's it for this week, folks, Catch you
- 42:17Speaker 1: next time.
