The Oil Education You Never Got
Let’s be real. Most of us were never taught how this beautiful body of ours actually works. Not in school. Not at the doctor’s office.
I had one high school health class — which, if we’re being honest, was more about avoiding gym and preserving a good hair day than anything else.
I memorized all 206 bones in the body… but no one taught me how seed oils mess with your metabolism. Or how linoleic acid (LA) gets stored in your fat cells and sticks around like that one ex who just won’t move on.
No one told me that the foods I was eating “because they’re heart healthy” were actually slowing me down, fogging my brain, and inflaming my joints.
And no one warned the so-called “heart healthy” oils I was cooking with were hijacking my mitochondria.
It’s Not You, It’s…
It’s the oils. Because you are not weak. You are not lazy.
And you sure as hell are not broken because you haven’t been able to “diet your way” to glowing health.
You’ve just been missing context — and it’s been kept from you for a reason. Not out of malice… but because educating you doesn’t make anyone rich. Medicating you? Now that’s a different story.
That’s where I come in.
I’m here to pull back the curtain, roll up our sleeves, and give you tools. Real ones.
Because once you understand how these sneaky seed oils work — how they’ve become the #1 fat in the American diet, and how they store in your body for YEARS — you won’t be able to unsee it.
And that’s a good thing. That’s a powerful thing.
Because once you know, you can say no.
You can say:
“Why would I pay someone to poison me?”
And choose something better. Cleaner. Smarter. Moxier.
Even if your vanity products get a tiny pass. We don’t judge here. We just detox what we can.
What Are Seed Oils?
Seed oils are ultra-processed fats extracted from things like soybean, sunflower, canola, and cottonseed using high heat and chemical solvents (like hexane). They’re cheap, shelf-stable, and found in nearly every packaged food, salad dressing, and restaurant fryer.
They didn’t exist 150 years ago. Now?
They’re the #1 fat in the American diet.
Common Culprits:
– Soybean oil
– Corn oil
– Canola oil
– Sunflower oil
– Safflower oil
– Cottonseed oil
– Grape seed oil
– Rice bran oil
Don’t be fooled by the “vegetable oil” label. It sounds innocent. It’s not.
The Rise of Linoleic Acid: A Timeline
Let’s break this down:
1860s – ~2g/day LA from real food (seeds, nuts, pastured animals)
1909 – Crisco is born; cottonseed oil enters homes
1950s–70s – Cholesterol fear boom; shift to “vegetable oils”
Today – 30g/day, mostly from cheap seed oils in processed food
That’s a 1,400% increase in a fat that oxidizes easily, stores in your tissues, and doesn’t burn clean.
Why It Matters: LA Is a Metabolic Time Bomb
Let’s break this down clearly—because once you understand how linoleic acid (LA) behaves in the body, you’ll never look at a “heart-healthy” label the same way again.
Linoleic Acid 101
Linoleic acid is an omega-6 polyunsaturated fat (PUFA). It’s technically essential in small amounts — but modern diets are flooded with it, mostly from cheap, highly processed seed oils.
Here’s the issue:
LA oxidizes easily — especially when heated during processing or cooking. Oxidized fats = free radicals = cellular damage.
Your body stores LA in fat tissue — it’s not burned off quickly like carbs or protein. It gets embedded in cell membranes and sticks around for months (even years).
LA triggers inflammation — its breakdown products (like 4-HNE) damage DNA, disrupt mitochondrial function, and contribute to insulin resistance.
It fuels weight gain — LA can impair leptin signaling (your satiety hormone) and reduce metabolic flexibility.
Translation? It’s not just what you eat — it’s what your body can do with what you eat. And too much LA gums up the works.
But the Sneaky Part?
LA is still marketed as “healthy.” Why? Because it lowers cholesterol on paper — but at the expense of oxidative stress and inflammation in real life.
Dr. Mercola, Dr. Cate Shanahan, and Chris Knobbe all agree: the dramatic rise in LA intake is a driver of the modern chronic disease wave — from obesity to infertility to brain fog.
Moxie Method: Detox Without the Drama
Let’s not over complicate it.
1. Purge the Pantry
Toss anything with:
– Soybean oil
– Canola oil
– “Vegetable oil”
– Shortening or margarine
These are the worst offenders.
2. Swap Smart
Use better oils for each situation:
– High heat cooking: Avocado oil, ghee, beef tallow
– Medium heat: Coconut oil, butter
– Cold prep: Extra virgin olive oil, walnut oil
3. Support Natural Detox
You don’t need another cleanse kit, colon purge, or powdered protocol to detox from seed oils. Your body already knows how to clean house — it’s built for it.
What It Needs Is Real Food
Whole foods contain the exact compounds your body uses to repair cell damage, quench free radicals, flush out toxins, and restore metabolic balance.
We’re talking bitter greens that trigger bile flow. Sulfur-rich veggies that fuel glutathione (your master antioxidant). Omega-3 fats that calm inflammation and stabilize cell membranes.
This isn’t trendy. It’s biology. And it’s your secret weapon in the fight against oxidative stress and stored-up linoleic acid.

Start with your oils. Clean up the fat that fuels you. Your hormones, brain, metabolism, and mood will thank you.
And if you ever feel overwhelmed?
Just ask yourself:
“Why would I pay someone to poison me?”
(Unless it’s lip gloss. Vanity products get a pass. 😉)
Seed Oils FAQ: What You Need to Know
What are seed oils and why are they bad?
They’re cheap, highly processed oils that are high in linoleic acid—an omega-6 fat that becomes toxic when oxidized and stored in the body.
Can linoleic acid really stay in the body for years?
Yes. LA integrates into your fat tissue and can linger for up to 600 days, silently impacting metabolism and hormone balance.
Which oils are safe to cook with?
Avocado oil, ghee, coconut oil, and grass-fed tallow are great for heat. Olive oil and walnut oil are better for cold use.
Do I need to cut all seed oils immediately?
No. Just reduce exposure where you can. Focus on swaps, not stress.
Is this about weight loss?
Not primarily. It’s about metabolic healing, energy, brain clarity, hormone balance—and feeling like yourself again.
