What If We’ve Been Eating Wrong This Whole Time? Rethinking the Human Diet

I began my health journey like many others - eat less, run more. As I dove deeper into the world of health, I got excited and started learning about human biology and following biohackers. Then came the influence of sustainability and conscious living, paired with the wellness world shouting that plants were the solution and meat was the villain. So, I went vegetarian. Then vegan. At the time, it felt right. Everyone was doing it, and it was marketed as the golden ticket to longevity and saving the planet. Win-win, right?
But slowly, things didn’t feel right. I was always snacking, never truly satisfied, gaining weight even though I was “doing everything right.”
That’s when I noticed that biohackers weren’t jumping on the vegan trend. Despite all the convincing documentaries on Netflix, they stayed grounded in science and kept presenting evidence that eating only plants doesn’t align with our human biology. I started asking deeper questions - not just “what’s healthy?” but “what’s human?” What are we actually designed to eat?
The Human Diet: What Biology and Ancestry Reveal
Humans evolved as omnivores - adaptable, yes, but with a strong natural pull toward animal foods. This isn't just a theory. It shows up in our biology.
• Stomach acid: Ours is highly acidic, like scavengers - designed to digest meat and kill pathogens.
• Brain fuel: Nutrients like DHA, B12, and creatine (only found in animal foods) were key to human brain development.
• Traditional tribes: From the Hadza to the Inuit, ancestral cultures prioritize meat when it’s available. Plants are used, but more often seasonally, medicinally, or as supplements rather than staples.
• Absorption matters: Animal foods offer nutrients in forms our bodies can actually use. Plant sources often come with barriers to absorption.
• Modern research: Many biohackers and health optimizers now center their diets around high-quality animal foods - because the benefits are hard to ignore.
Nutrients: It’s Not Just What You Eat, It’s What You Absorb
Animal foods give us nutrients in the most usable forms:
Heme iron (vs. plant iron, which is harder to absorb)
Retinol (true vitamin A) vs. beta-carotene
DHA & EPA (from fish) vs. ALA (from flax or chia, poorly converted)
Complete proteins with the right amino acid ratios
And things like B12, zinc, selenium - basically nonexistent in plants
On top of that, plants often come with antinutrients like oxalates, lectins, and phytates that block absorption and irritate the gut.
That “colorful, plant-based” plate might look good… but your cells might still be starving.

The Modern Diet Has Taken Us Far from Our Roots
Today’s food environment is a far cry from what we evolved with.
Ultra-processed food has replaced real ingredients
Seed oils (omega-6 heavy) are in everything - driving chronic inflammation
Refined sugar + grains = insulin chaos
Soil is depleted, produce is hybridized for sweetness, not nutrients
Even the animals we eat are often fed unnatural diets resulting in lower omega-3s, toxins in fat
We’ve moved from nutrient-dense and seasonal, to hyper-palatable and empty.
So, What Should We Eat in 2025 and Beyond?
Forget extremes. Think: ancestral meets practical.
A real human diet should be built on:
Grass-fed meats (beef, lamb, goat)
Nose-to-tail nutrition: liver, heart, bone broth
Properly sourced seafood
Eggs, raw dairy (if tolerated)
Low-toxicity, seasonal plants (berries, herbs, roots)
Ferments for the gut
Real fats: ghee, tallow, coconut oil
Avoid: seed oils, refined sugar, synthetic additives
It’s not about restriction. It’s about remembering what actually nourishes.
And It’s Not Just About Food
Optimal health isn’t only what’s on your plate. It’s how you live:
Sunlight, early and often
Movement, not just workouts — walking, stretching, playing
Breathwork, cold exposure, touch, nature
Fasting, not grazing all day
Connection, purpose, awe
The modern world is unnatural. So staying healthy means being intentional and countercultural. It might sound scary to some, but don't worry about living differently, be the unicorn that inspires others.
My Story, Continued
After reconnecting with these basics, everything started to make more sense.I stopped blaming myself for “not thriving” on plants. I saw how eating fake meat and buuter, and chickpeas wasn’t feeding my cells - it was feeding a trend.
And I came back to what actually works: real food. An animal-based, omnivorous diet that honors both my biology and my intuition. Best of all, when done right through regenerative farming, it heals not just your gut, but also the planet.
For most people, vegan and carnivore diets are powerful reset tools - not lifelong solutions! That’s why they might feel great at first, but over time, energy can decline and inflammation can rise. The sustainable middle ground? An omnivore diet rooted in high-quality animal foods, supported by plants that work for your body.
You don’t need to fear food. You just need to listen more closely - to your body, to nature, to common sense.
If you’re navigating food confusion, you’re not alone. I’ve been there.
And if you're ready to strip it all back and rebuild in a way that feels right - I offer free discovery calls and a guide to ancestral eating to help you reconnect with the basics.
Because simplicity is not boring. Simplicity is freedom.
