This is Thomas Seyfried.

He's a scientist who's dedicated 30+ years to researching cancer.

His message? Cancer IS preventable.

It's caused by lifestyle factors, not genetics.

Here are Seyfried's 7 MOST important rules for preventing cancer: Image
7. Maintain stable blood sugar levels.

Glucose & insulin spikes can feed cancer cells.

Seyfried emphasizes the importance of keeping blood sugar levels stable by avoiding:

• Sugar
• Refined carbs
• Processed foods

Diets high in sugar can also lead to chronic inflammation & increase the risk of cancer development.
6. Ketogenic Diet.

Seyfried advocates for a ketogenic diet:

• High-fat
• Moderate-protein
• Low-carbohydrate

This diet shifts the body from using glucose as its primary energy source to burning fat & ketones.

Since cancer cells primarily rely on glucose for growth...

Limiting glucose starves cancer cells & supports metabolic health.

Foods you'd consume on this diet:

• Nuts
• Olive oil
• Avocados
• Low-carb vegetables
• Lean proteins (Ex. fish)
5. Reduce Inflammation.

Chronic inflammation is linked to cancer.

Seyfried advises adopting an anti-inflammatory lifestyle, which includes:

• Avoiding processed foods & sugar
• Consuming anti-inflammatory foods (turmeric, fatty fish, green tea, etc)
• Reducing stress through things like meditation, deep breathing & proper supplementsImage
4. Fasting.

Seyfried is a big advocate for both intermittent fasting & longer-term fasting.

Fasting reduces blood glucose & enhances ketone production...

Which cancer cells cannot efficiently use.

This helps inhibit their growth & promotes autophagy (the body’s process of cleaning out damaged cells).
3. Reduce Stress.

Chronic stress damages the mitochondria & increases inflammation in the body.

As we've learned...

These 2 are major drivers for causing cancer.

Reducing stress can look like:

• Meditation/breathwork
• Prioritizing rest & recovery
• Taking natural supplements (L-theanine, Cordyceps mushrooms, etc)

Here's a video of myself & my partner explaining the dangers of stress:
2. Regular exercise.

Seyfried emphasizes regular exercise as VITAL for preventing cancer by:

• Improving mitochondrial function
• Lowering blood sugar and inflammation
• Supporting autophagy to clear damaged cells

Here are some forms of exercise anyone can do:

• Walking
• Swimming
• Strength training

Any form of movement is better than none.

Simply moving your body daily is the goal.
1. Prioritize sleep.

Sleep is when our body recovers & heals itself.

Especially our mitochondria.

The better & the more sleep we get, we better our body is able to do this.

Which means it's absolutely vital for preventing metabolic damage & cancer.

Here are 4 sleep hacks from Dr. Eric Berg:
Young adult cancers are up 79% in the last 10 years.

People's genetics didn't suddenly get that much worse...

So it must be related to our lifestyles:

• Processed foods
• Too much sugar
• Being sedentary

It's up to us to fight back.

Don't become a victim of the American Healthcare system.
What do you think of Thomas Seyfried's recommendations?

Did he miss any?

I'm looking to help 5 men:

• Burn fat
• Build muscle
• Get into the best shape of their life

All based on personal labs.

No guesswork.

Your doctor will never tell you this…

But these 9 biomarkers show why you can’t lose fat and keep gaining weight no matter what you try:

1. Fasting Insulin → Fat Storage Signal Image
High fasting insulin means your body stays in fat-storage mode (even when you're eating less)

When insulin is chronically elevated, fat burning becomes biologically impossible. Image
2. HOMA-IR → Insulin Resistance Severity

This shows how resistant your cells are to insulin.

High HOMA-IR = glucose can’t enter cells → insulin stays high → fat stays on.

Most “diet failures” are insulin resistance problems.

Standard labs miss what kills you.

Here are the 9 biomarkers that predict lifespan, disease risk & how your body ages:

1. ApoB (True Heart Disease Risk) Image
Standard cholesterol tests measure LDL.

But ApoB measures the actual number of atherogenic particles in your blood.

High ApoB = high cardiovascular risk, even if your LDL looks "normal."

This is the number that actually predicts heart attacks. Image
2. hs-CRP → Chronic Inflammation

hs-CRP (high-sensitivity C-reactive protein) measures systemic inflammation.

Chronic inflammation drives heart disease, cancer, diabetes & neurodegeneration.

If your hs-CRP is elevated, your body is under constant inflammatory stress (even if you feel fine)Image

I saved my brother’s life.

He was obese, had chest pains & our mother thought we were losing him.

So I moved in with him & helped him drop 52 lbs in 90 days (steal the exact protocol): Image
The first and most important thing you need to focus on to lose weight?

Your diet.

The meal plan we used:
⤑ 3 meals a day, spaced 5 hours apart.

PS. We ate whole foods, stayed in a deficit & never mixed fats with carbs:
For lunch, we kept it simple:

• Lean protein (salmon, chicken +)
• Veggies (broccoli, sweet potato, etc.)
• Healthy fats (avocado, eggs, etc.)

Dinner looked like this:
• Lean meats
• More veggies
• Clean carbs (fruit, sweet potato, etc.)

The goal was fat loss without starving or burning out (something all of you need to copy):

I’ve been testing peptides for over 5 years...

So here are the top 5 fat-loss peptides that helped me get more shredded than your favorite Hollywood star at 44:

1.Retatrutide Image
A next-generation peptide that targets three hormones (GLP-1, GIP & glucagon) at the same time.

It helps reduce hunger, improves blood sugar control & increases fat burning.

Phase 3 trials showed up to ~28% bodyweight loss (one of the highest results ever recorded in obesity treatment):
With Retatrutide (0.6mg every other day, guided by labs), I went from 178.7 lbs at 11.9% body fat to 172.8 lbs at 7.2% (dropping ~9 lbs of fat while gaining 1.5 lbs of muscle)

With no starving or suffering: Image

If you’re overweight and want to lose belly fat in 2026…

Here’s the exact 11-step protocol to drop 20+ lbs in 90 days (without starving):

Step 1: The 3x5 Diet
3 meals per day. 5 hours apart. No snacking.

Breakfast + lunch: protein, veggies, fats (no carbs).
Dinner: protein, veggies, carbs (no fats).

Avoid fats and carbs in the same meal (this helps prevent insulin spikes that lead to fat storage).
Step 2: Protein First (Always)

Protein keeps you full longer.

When you eat protein first, then veggies, then fats or carbs last, you naturally eat less without forcing it.

PS: Aim for 1g of protein per pound of bodyweight per day.

In 2025 you ate 40+ credit cards worth of plastic.

These microplastics sit inside your body (heart, brain, testicles) & are linked to 10+ deadly diseases.

In this thread, I'll show you the only proven ways to detox them & how to avoid the hidden sources you're exposed to daily:
Microplastics have been linked to 20+ diseases – including cancer, 4–5× higher heart attack risk, and gut–brain damage.

Around 80% of us are already contaminated, so let’s start with the best way to stay safe: lifestyle changes (then we’ll cover how to detox a portion of them):
Of course, you avoid the obvious ones:
• Plastic cutting boards
• Plastic bottles
• Glass bottles (yes, they can contain microplastics too – read till the end to see how)
• Plastic coffee cups
• Plastic Tupperware
• Teflon pans

But the goal of this post is to expose the sneaky sources most people miss – so let’s get into it:
