This is Thomas Seyfried.
He’s a professor of biology, who’s studied cancer for 30+ years.
His message? Cancer isn’t bad genes or bad luck—it’s damaged mitochondria.
This flips everything you’ve been told about how to treat & prevent cancer: 🧵

This flips everything you’ve been told about how to treat & prevent cancer: 🧵
1/ Cancer rates are on the rise, why?
- 1,676 people die daily from cancer in the U.S.
- Young seemingly healthy people are being diagnosed more often than ever.
- Billions spent, yet the "war on cancer" failed.
Seyfried: We're hitting the wrong target.

Seyfried: We're hitting the wrong target.
2/ Mainstream dogma: "Cancer is a genetic disease caused by DNA mutations.”
Seyfried: Wrong.
DNA damage is a symptom, not cause.
Real cause: Damaged mitochondria
Healthy mitochondria = NO cancer.
Seyfried: Wrong.
DNA damage is a symptom, not cause.
Real cause: Damaged mitochondria
Healthy mitochondria = NO cancer.
3/ Big idea #1: Mitochondria, not the genes, determines if a cell becomes cancerous
When cells can’t make energy with oxygen, they switch to the ancient fermentation pathway.
Cancer thrives by burning glucose & glutamine without oxygen.
Uncontrolled cell growth follows.

4/ Seyfried builds on Otto Warburg’s forgotten theory.
Warburg won the 1931 Nobel Prize in Medicine.
He observed cancer cells ferment sugar even with oxygen (Warburg Effect) and believed cancer was metabolic, not genetic.
Modern science ignored him.
Seyfried didn’t.

5/ Proof from research?
Damaged DNA + healthy mitochondria = NO cancer
Healthy DNA + damaged mitochondria = CANCER
DNA isn't the trigger, it's downstream damage.

Healthy DNA + damaged mitochondria = CANCER
DNA isn't the trigger, it's downstream damage.
6/ Research from the visionary biologist Michael Levin supports this:
Cancer is a disease of failed bioelectric signaling, not genes.

7/ Big idea #2: All cancers are one disease: damaged mitochondria.
Yet medicine divides tumors by organs (breast, lung, brain).
We're treating symptoms, not the root cause.

8/ Dr. Jason Fung, MD, author of "The Cancer Code", agrees:
Cancer isn’t just a genetic disease, it’s a disease of bioenergetics.
Standard treatments often fail because they ignore the root cause: dysfunctional metabolism.

9/ “But what about BRCA1, or other inherited cancer genes?”
Even that links back to mitochondrial dysfunction.
These genes affect mitochondrial proteins in the electron transport chain—key to energy production.
They raise risk. They don’t cause cancer alone.

10/ What damages mitochondria?
- Ultra-proccessed foods, high carb at wrong seasons
- Insulin resistance
- Chronic inflammation
- Lack of exercise & movement
- Poor sleep
- Chemical toxins, heavy metals, mold
- EMFs (Wi-Fi, 5G)
- Chronic Stress
- Viruses (HPV, Hepatitis)
- Artificial Blue Light
To name a few.

11/ Seyfried’s approach to cancer:
- Get body into nutritional ketosis (Glucose/Ketone Index < 2.0) via ketogenic diet or fasting
- Press glucose & pulse the glutamine with targeted drugs
- Bonus: Hyperbaric oxygen therapy
- Get body into nutritional ketosis (Glucose/Ketone Index < 2.0) via ketogenic diet or fasting
- Press glucose & pulse the glutamine with targeted drugs
- Bonus: Hyperbaric oxygen therapy
12/ Nutritional Ketosis
Cancer cells depend on glucose & glutamine. They can’t efficiently use ketones or fat for fuel.
High ketones + low glucose = cancer-starving state.
Seyfried: Measure, don’t guess.
You can use a Keto-Mojo meter to track ketones & glucose.

13/ Important Caveat #1: Glutamine
Glutamine is essential for our immune function—you don’t want to eliminate it long-term.
It's the most abundant amino acid in the body & diet alone won’t block it.
That’s why Seyfried uses pulsed drug strategies to temporarily target it.

14/ Hyperbaric Oxygen Therapy (HBOT)
Seyfried sees it as a metabolic add-on.
When used with keto + glucose restriction, HBOT floods tumors with oxygen.
Normal cells benefit from the oxygen boost.
Cancer cells can’t handle the oxidative stress, they get stressed & die.

15/ "But chemo/radiation save lives..."
True, but with serious long-term damage.
Metabolic therapy is safe & effective, yet ignored.
Why? No profit in fasting, ketosis.

16/ Important Caveat #2: Seyfried isn’t entirely against chemo, radiation, immunotherapy, or surgery.
His view: if you first weaken the tumor with metabolic therapy, then low-dose chemo or immunotherapy can work better.
What he opposes: blasting the brain with radiation.

17/ Seyfried: Never Radiate the Brain
Seyfried’s research shows that brain radiation frees up massive amounts of glucose & glutamine…
…the exact fuels brain tumors thrive on.
His advice: avoid brain radiation.

18/ “If this is true, why isn’t it mainstream?”
Because metabolic therapy isn’t part of standard care.
Doctors aren’t trained in it, no billing code for it—
And doctors risk losing their license if they go off-guideline.
The system rewards treatment, not prevention.

19/ Here’s the disconnect in 2025:
Larry Ellison spoke at the White House pushing gene sequencing + mRNA cancer vaccines.
But if cancer starts with mitochondrial dysfunction, targeting genes is missing the point.
Still, billions flow to genetics, while metabolism is ignored.

20/ Seyfried’s bottom line:
You don’t get cancer if your mitochondria is healthy.
Period.
Cancer doesn’t happen overnight, start early, protect your mitochondria to prevent cancer.

- Daily sunlight exposure
- Grounding (barefoot outdoors)
- Blue light protection after sunset
- Zone 2 cardio + HIIT
- Strength training
- Cold exposure (showers/plunges)
- Sauna
- Meditation, journaling, visualization
- Find purpose & live in alignment
- Dental hygiene
- Limit EMFs (Wi-Fi, Bluetooth, 5G)
- Seafood 3-5x a week
- Walking 7.500-10.000 steps
- Nasal breathing
- Test, don’t guess
