We all want to feel sharper. More focused. Less foggy.
But most people are looking in the wrong place.
It’s not in the nootropics, adaptogen lattes, or mushroom powders.
It’s in the stuff we’ve been told to fear: animal fat.
That’s right—your brain is built on saturated fat, cholesterol, and DHA. And when you deprive it of those building blocks, it doesn’t just run slower… it suffers.
Let’s talk about why eating ancestrally isn’t just good for your gut or hormones—it’s how you feed your brain.
Your Brain Is Mostly Fat (and Cholesterol)
60% of your brain is fat.
And around 25% of your body’s cholesterol is in your brain. That’s not a mistake—it’s by design.
Cholesterol isn’t clogging up your brain like old plumbing. It’s there to:
- Maintain cell membrane structure
- Build and repair neurons
- Allow for proper synapse signaling (a.k.a. brain speed)
- Help produce neurosteroids (which affect mood, memory, and alertness)
When your body doesn’t get enough dietary cholesterol and saturated fat, it has to work overtime to make its own—and it may not be enough to support high-performance thinking.
Enter DHA: The Brain’s Favorite Fat
DHA (docosahexaenoic acid) is a long-chain omega-3 found only in animal products—especially fatty fish, egg yolks, and grass-fed meat.
Your brain LOVES DHA. It:
- Makes up about 10–20% of your brain’s total fat
- Supports cognitive function and memory
- Helps form myelin, the protective sheath around neurons
- Plays a key role in neuroplasticity (your brain’s ability to adapt and grow)
Plant-based omega-3s (like ALA from flax or chia) don’t cut it. Your body has to convert ALA to DHA, and the conversion rate is less than 1%.
So unless you’re eating real animal fat, your brain is running on fumes.
Low-Fat Diets? A Disaster for Brain Health
Still scared of fat and cholesterol? That’s the real problem.
Low-fat, plant-based diets often lead to:
- Brain fog and low energy
- Hormonal crashes (your brain needs cholesterol to make sex hormones)
- Depression and anxiety
- Short-term memory loss
- Increased risk of neurodegenerative disease
Let that sink in: The very thing we were told causes heart disease and “clogs arteries” is the thing your brain is starving for.
The Carnivore Clarity Is Real
When people go animal-based or carnivore, one of the first things they report is:
“My mind feels clearer than it has in years.”
That’s not a placebo—it’s neurochemistry.
Why it happens:
- Zero plant toxins = less inflammation in the brain
- More saturated fat = better membrane function
- More DHA = faster nerve signaling
- Higher cholesterol = stronger mental resilience
- Stable blood sugar = steady cognitive focus
It’s why you can go from needing three cups of coffee just to function…
to waking up clear-headed and dialed in.
What I Eat for Brain Power
If you want a sharper brain, start by feeding it what it’s made of:
– Pastured egg yolks (don’t throw out the best part)
– Grass-fed beef
– Beef liver or cod liver (rich in retinol + DHA)
– Fatty fish like salmon or sardines
– Raw milk or raw cheese (if tolerated)
– Tallow, butter, ghee for cooking
– Bone marrow and brain (next-level but worth it)
These are the foods your brain recognizes. They’re not “hacks”—they’re what humans evolved on.
Final Thoughts: Want a Better Brain? Eat Like One
Your brain isn’t crying out for seed oils and soy lecithin.
It’s asking for real food. Ancestral fat. Nutrients that work with your biology—not against it.
Want clarity, memory, focus, and better mood regulation?
Start with what your brain is made of: fat, cholesterol, and DHA.
