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:
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.
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.
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
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/ “What about BRCA1 and other inherited cancer genes?”
They also connect back to mitochondrial dysfunction.
These genes influence mitochondrial proteins involved in the electron transport chain, which is essential for energy production.
They increase cancer risk but aren’t sufficient to cause it on their own.
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
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
12/ 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.
13/ 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.
Fasting for 72 hours is the best medicine on Earth.
It triggers your body to "eat up" tumors, inflammation, and toxins.
It's literally a doctor within.
Here's how to fast correctly (according to science):
Most people think fasting is just about weight loss or giving your digestive system a break.
But the "magic" occurs at the cellular level through autophagy.
This is where your body literally begins to eat itself.
Let me explain:
Autophagy = the cell’s self-cleaning process
When you fast for an extended period, your cells begin to break down and recycle damaged proteins, faulty mitochondria, and even potentially cancerous cells in their early stages.
It’s like your body finally gets a chance to clear out the built-up waste that contributes to inflammation and illness.

Autophagy: The Cell’s Self-Cleansing Process
During extended fasting, your cells kick into cleanup mode—breaking down and recycling damaged proteins, malfunctioning mitochondria, and even early-stage potentially cancerous cells.
It’s like giving your body a much-needed opportunity to clear out accumulated waste that can lead to inflammation and disease.
