(…and why you probably shouldn’t either)
The Panic Lab Report
It happens almost daily.
A patient sits down across from me like they’ve just gotten a letter from the IRS. They slowly slide the lab printout across the desk like it’s a Soviet secret. Their voice trembling.
“Doc… my LDL is 142. Am I going to die?”
From what? Did you accidentally brush up against an alien craft at Area 51? Open Hunter’s laptop by mistake? God forbid hack into Hillary’s emails on your work computer? Or worse – eat the rest of Amanda’s Cheez-It’s in the nurses’ station?
Uh – no. Not from that number, you’re not.
Cue the awkward silence – you could hear a statin pill drop.
I know I’ve talked about what cholesterol is, what it does, the good, the bad, the ugly, the tragic misconceptions between lipids and lipoproteins by even our leading healthcare providers before, but I’m bringing it up again. I’m going to need to do a series on this because there’s so much to clear up. The lie is in there deep. Way in there. The truth is, somewhere along the way, we got brainwashed into thinking cholesterol is this rogue villain sneaking into your arteries at night, laying down plaque like concrete, and cackling about your impending doom.
Meanwhile, the reality is way more complicated than that – and potentially way less sexy to pharmaceutical shareholders. At the very highest level, cholesterol is a repair molecule. Your body literally makes it on purpose, like an in-house maintenance team. It’s not some outlaw molecule that breaks in and trashes the place.
Welcome back to The Dysfunction Files, where we dig through the medical dumpster fire to find the truth they’d rather you didn’t see. I’m Dr. Kristen Lindgren, and today we’re cracking open one of the most stubborn medical myths of all time – Cholesterol.
If you’ve ever been told your total cholesterol or LDL is a death sentence, if your doctor’s ever threatened you with a statin prescription or you happen to be taking one right now, this episode is for you. I’m about to tell you why I don’t give a flying f* about your cholesterol and why you probably shouldn’t either. Those numbers do mean something but it’s not what you think.
Let’s get into it.
How We Got Here: The Cholesterol Myth Origin Story
To understand how we all ended up in this cholesterol clown car, we have to go back to the 1950s. Don’t worry – I won’t drag you all the way through the mud of this story – just a little bit of background.
Enter Ancel Keys – a researcher who decided fat was the root of all heart disease. He conducted what became known as the Seven Countries Study. Only problem? He had data from 22 countries but cherry-picked the seven that fit his “fat = bad” agenda. This wasn’t groundbreaking science. It was more like Instagram influencer who deletes posts that don’t fit the aesthetic. Got me? Classic.
From that shaky foundation, we got the Diet-Heart Hypothesis which goes something like this:
Eat fat → cholesterol rises → arteries clog → heart attack.
The problem? There was no causal proof of this. But it was catchy. It was simple for any average American to understand. And it was the perfect setup for an industry ready to monetize fear – oh, and sugar. The sugar industry funded the studies – I digress.
By the 1980s, the low-fat craze had us drowning in SnackWells cookies and margarine — they may have been killing us, but they were delicious — and we were getting sicker and fatter than ever.
Conveniently, this was also when statin medications hit the scene. Funny little world, right? Almost like the industry had been quietly funding the “research” on fat, cholesterol, and cardiovascular disease the whole time. I’m sure they weren’t. Probably. Maybe.
Suddenly, doctors had a shiny new pill to “fix” your cholesterol. Lower the number, lower the risk. And off to McDonald’s you go — heart disease “cured.” Or so we thought.
The Problem With Your Single Cholesterol Number
If your doctor’s entire interpretation of your cardiovascular risk can be summed up by one number – “total cholesterol or even LDL cholesterol” – run. That’s like judging someone’s financial health by their Venmo balance. Context-free nonsense. At least give me a lipoprotein breakdown and some metabolic markers before you even attempt to quantify my risk.
The first correction: there is no such thing as “good” or “bad” cholesterol. Cholesterol is cholesterol. It’s the same big clunky complicated molecule whether it’s floating in HDL or LDL. The difference is the lipoprotein carrier shuttling it around. That’s it. HDL and LDL stand for “high density lipoprotein” and “low density lipoprotein” – not “good” or “bad.”
Cholesterol is a lipid made by every cell in your body, and it needs to travel around the body from cells that make a surplus to cells that are in need. It hasn’t figured out how to teleport yet, so it does so via the bloodstream. Your blood is mostly water. Cholesterol is like oil. You all know how well oil and water mix – so just sending oily cholesterol into the watery bloodstream is a problem. To solve this issue, God made something called ‘lipoproteins,’ which are exactly what they sound like they are. Small molecules made of water-soluble protein on the outside and oily lipids on the inside to carry cholesterol around from place to place.
Think of cholesterol like passengers – let’s say the good people of Green Bay, WI, just trying to get to work on time. They’re all humans (you know, excluding the 3% grays, Nordics, insectoids, and reptilians – no disrespect to the starseeds out there). But whether they’re being ferried safely in a big, sturdy city bus (HDL) or jammed into a sketchy Uber Prius with a murderous underpaid driver (small, dense LDL) determines how smoothly traffic flows. Things are more complicated than this, but at a high level, think:
- HDL (the bus): Super efficient at return trips, shuttling cholesterol back to the liver for recycling.
- LDL (the Uber): Carries cholesterol outward to repair tissues, which is essential — until it meets oxidative stress, starts denting cars, and clogging up the coronary walls.
Particle Size Matters
- Small, dense LDL: Rusty sedans weaving through traffic, sneaking into tight arterial spaces, more likely to oxidize.
- Large, fluffy LDL: Tour buses. Big, but not slipping through chain-link fences.
Particle Number (LDL-P)
- More particles = more traffic = more accidents.
- Fewer, larger particles = less chaos, lower risk – even if total cargo looks high.
That’s why advanced lipid testing (NMR, CardioIQ) can help better quantify risk in terms of what’s going on with the lining of your blood vessels – most importantly the ones that service your heart and brain. It tells you not just how many passengers you’ve got, but what kind of vehicles they’re riding in.
And don’t forget: about 80% of your cholesterol is made by your liver – because it’s essential. Cut it from your diet and your body just… makes more. Remove your liver’s ability to make it and well, none of us would be here having this discussion in the first place. End of story. Full stop. There are rare genetic conditions that dramatically impair cholesterol synthesis – those pregnancies don’t make it.
The Importance of Cholesterol for Health
Here’s what doctors often forget to tell you: cholesterol isn’t optional. Again, every single solitary cell in your body makes it, but your liver cells make the most because demand is constant.
Why cholesterol matters:
- Hormone backbone – Cholesterol is the raw material for estrogen, progesterone, testosterone, cortisol, and aldosterone.
- Cell membranes – Cholesterol keeps membranes stable but flexible, like rebar in concrete. Without it, your cells literally fall apart.
- Nerve protection – It makes up myelin sheaths, the insulation on your nerve wiring.
- Vitamin D – Synthesized from cholesterol in your skin when exposed to sunlight.
- Digestion – It’s the starting point for bile acids, which help you absorb and digest fats.
So when you hear “lower cholesterol at all costs,” “everyone over 40 should be on a statin” – remember: you’re lowering one of the most fundamental building blocks of life. Your body doesn’t crank out cholesterol because it’s confused. It does so because you’d die without it.
Cholesterol as the Repair Crew
This is the part that blows patients’ minds: cholesterol isn’t lurking in your arteries like some serial killer waiting to strike. It’s actually your first responder team.
When the inner lining of your arteries (the endothelium) gets damaged — from high carbohydrate diets (you know – the low fat diet still recommended by cardiologists), toxins, smoking, chronic stress, or just the wear and tear of modern life — your body sends cholesterol to patch it up. Think spackle.
Blaming cholesterol for heart disease is like blaming firefighters for showing up at a fire. They’re not the problem; they’re the ones putting out the flames.
Or think about road repair crews. When you see guys filling potholes on the highway, you don’t call the cops and have them arrested for “causing potholes.” You understand the real culprit was weather, traffic, or that one guy in the rusted-out Chevy with no shocks.
Here’s the deal: without cholesterol, those cracks would stay open. And just like any open wound, they trigger the clotting cascade, which is far more dangerous than having the spackle around. The spackle by itself doesn’t cause an acute cardiovascular event or stroke – it’s the clotting.
In other words:
- Cholesterol doesn’t cause vascular disease.
- Cholesterol shows up because there’s already damage to the endothelial lining.
It’s not the arsonist. It’s the duct tape. And if you rip out the duct tape without fixing the leak, you’re left with a much bigger mess.
The Real Bad Guy: Oxidative Stress and Inflammation
Cholesterol isn’t the danger. Inflammation and oxidative damage is. Once low-density lipoproteins get damaged by free radicals and inflammation, it turns sticky and pro-inflammatory – that’s when plaque starts.
Culprits for oxidation include:
- Refined sugar & carbohydrates (bagel, not butter)
- High fructose corn syrup
- Industrial seed oils (soy, corn, canola — the inflammatory trifecta)
- Smoking
- Chronic infections (Lyme, EBV, CMV, co-infections)
- Heavy metals & environmental toxins
- Sedentary lifestyle
- Chronic stress
High cholesterol without inflammation? Often protective. We know that in older folks, it’s actually LOW total cholesterol levels that are associated with younger life expectancies.
High cholesterol with inflammation? Houston, we have a problem.
What Actually Matters More Than LDL
If we were serious about preventing heart disease, we’d stop treating LDL like the sole villain and start looking at the full picture. There are actually other labs that give us better insight into what’s going on inside the arteries. Not that we can’t make inferences from just LDL, HDL, VLDL, and triglycerides, but there’s a whole cast of characters involved in this true crime story. Like all true crime storie,s of course…
- hsCRP – systemic inflammation.
- Homocysteine – vessel damage + clot risk.
- Fasting insulin – the silent heart disease driver.
- Triglyceride-to-HDL ratio – simple insulin resistance marker.
- Lp(a) – sticky, genetic lipoprotein risk.
- Coronary calcium score – shows the amount of actual calcified plaque which isn’t what kills you but is highly highly predictive of a vascular event.
- ApoB – the total headcount of all atherogenic lipoproteins.
So again, cholesterol is just the cargo – not the culprit.
But, like everything else, none of these numbers or imaging studies exists in a vacuum. Context still matters: high ApoB, for example, in an inflamed, insulin-resistant patient = high risk. High ApoB in a metabolically healthy person with no inflammation? Different story.
The Statin Side Quest
Let’s be clear: statins have a place.
- Just had a heart attack? Inherited something called familial hyperlipidemia (typically total cholesterol levels well over 300 – happens in about 1 in 250 people). Extremely high triglycerides in the setting of a low HDL? Yes, they can potentially help – at least for a period of time until we can get metabolic markers back online.
- Statins also have mild anti-inflammatory and mild blood thinning effects. If they have any real cardiovascular benefit (the debate we can revisit in part 2), I would argue it’s due to these properties and these alone.
But for everyone else? The benefits are debatable – especially for women and older adults – while the side effects are very real:
- Muscle pain and weakness
- Fatigue
- Liver toxicity
- Brain fog and memory issues
- Lowered CoQ10
- Increased type 2 diabetes risk – like a 30% increased risk. And what’s the biggest risk factor for heart disease? It’s not high cholesterol. It’s not even smoking. It’s type 2 diabetes. Make it make sense.
The Functional Medicine Perspective
So, when I read a lipid panel, I don’t think, “How do we nuke this LDL?” I think, “What’s your body trying to repair?”
I look at:
- Total TG number, total HDL
- The ratio of TG to HDL
- Particle size and number
- Signs of metabolic syndrome (a1c > 5.3, high fasting insulin, high fasting blood sugar
- Signs of inflammation
- Thyroid function (low thyroid = higher cholesterol)
- Hormone balance (cortisol, estrogen, testosterone, growth hormone)
- Nutrient status (vitamin D, magnesium, omega-3s)
- Gut health (yes, it affects cholesterol metabolism)
Instead of drugging the numbers, I:
- Swap processed junk for real food – high fat low carb diets are anti-inflammatory – not the other way around
- Promote fasting and intermittent fasting to drive down insulin levels and support natural blood sugar metabolism
- Boost anti-inflammatory fats (omega-3s, olive oil, grass-fed butter)
- Prescribe resistance training to build metabolic resilience
- Further investigate blood sugar levels with continuous glucose monitoring and add in nutriceuticals to keep levels low and steady
- Support detox so the liver can clear fats and toxins efficiently
Why I Don’t Give a F* About Your Cholesterol (But I Do Care About Your Health)
So the next time someone tries to scare you with a “high cholesterol” number, remember:
- Your liver made it for a reason.
- Cholesterol isn’t the villain, it’s the duct tape.
- The real culprits are oxidative stress and chronic inflammation.
The relationship between cholesterol and atherosclerosis or damage to the lining of critical blood vessels is a complicated one – one that very much centers around sugar and not lipids. The cholesterol abnormalities we see in the setting of high risk patients are almost always the result of the real problem, not the cause. Taking statins without fixing the root cause is like ripping duct tape off a leaking pipe without fixing the pipe itself. Messy. Short-sighted. And guaranteed to just make things worse.
