This might save your life:

Harvard professor Daniel Lieberman spent 17 years studying how ancient humans slept, moved, and aged over centuries.

The 5 myths he debunked will change how you think about health forever:

1. Myth: Sitting is killing you

Not exactly…

Hunter-gatherers sit just as much as modern people.

The difference is that they get up every 10–15 minutes.

Sitting isn’t the issue; uninterrupted stillness for way too long is.

2. Myth: You need 8 hours of sleep

Most traditional cultures don’t sleep 8 hours.

Lieberman and his colleagues tracked people with no phones, no electricity, no alarms through the centuries.

6 to 7 hours per night and naps.

So, where did 8 hours come from?👇

I used to aim for 8 hours every night and still woke up tired.

I thought sleeping more was the answer...Turns out, quality matters more than quantity.

Magnesium glycinate is clinically proven to calm your nervous system and support deep sleep…

3. Myth: Cancers are inevitable.

74% of diseases are preventable, including Alzheimer’s and heart disease.

Yet the U.S. spends just 3% of its healthcare $ on prevention.

Physical activity boosts DNA repair, clears brain waste, lowers insulin, and reduces chronic inflammation.

Retirement is when the body starts deteriorating:

• Mitochondria die
• Muscles shrink
• Inflammation rises
• Brain fog increases
• Repair processes shut off

Ancient humans moved till old age, working, walking, and helping the tribe.

4. Myth: Cardio for weight loss.

Wrong.

Exercise (especially cardio) has modest effects on fat loss.

Its true value:
• Brain health
• Cancer prevention
• Longevity
• Muscle preservation
• Reduced dementia risk

Just not efficient for fat loss.

5. Myth: Your genes decide everything.

Genetics matter.

But Lieberman says:

“Genes load the gun. Environment pulls the trigger.”

Your choices—movement, food, sleep, mindset—shape your health far more than you think:

Your body “dies” when your heart stops.

But your heart ages faster than the rest of your body.

Heart disease is the leading cause of death than all forms of cancer and accidents combined.

Here’s how to reduce the age of your heart by 20 years:

66% of heart deaths happen with no symptoms.

You don’t feel it as pain, you feel it as:

• Poor sleep
• Random anxiety
• Fatigue after small efforts
• Shortness of breath walking up stairs
• Cold hands and feet

These are signs of declining cardiovascular efficiency.

Over time, it gets worse:

• Arteries stiffen
• Inflammation builds
• Blood pressure rises
• Blood vessels clog
• Insulin resistance sets in
• Recovery slows down

Eventually, this leads to:
• Chest pain
• High blood pressure
• ED (men)
• Stroke or heart attack

4 HORSEMAN OF DISEASE:

Cancer, heart disease, diabetes, and Alzheimer's.

Here are 5 fixes anyone over 35 should know (& can save your life):

1. Insulin resistance

Problem #1: Insulin resistance

Affects up to 88% of U.S. adults.

High insulin:
– Triggers arterial plaque (heart disease)
– Fuels tumor growth via IGF-1 (cancer)
– Leads to type 2 diabetes
– Starves neurons of energy (Alzheimer’s)

It’s the earliest and most common failure:

Fix #1: Reverse insulin resistance

Proven interventions:
• 30+ min of walking daily
• Lower refined carb intake
• Increase fiber and protein
• Berberine
• Fasting
• Strength train 3x/week

You can reverse insulin resistance in months.

Grey hair is not aging.

1 in 4 people are turning grey before 30.

Here are 6 science-backed foods for thick & dark hair:

1. Eggs (with yolk)

Nature’s multivitamin for your hair.

Biotin, zinc, sulfur, and protein in one.

Biotin builds keratin, and sulfur boosts shine and hair structure.

2/ Liver (beef or chicken)

Nature’s most concentrated source of hair nutrients:

B12, folate, iron, copper, and biotin.

Supports red blood cell flow, melanocyte health, and keratin production.

You've been lied to.

The foods they say are making you fat…Actually helps you lose weight.

Eat these 7 foods every day:

1. White Rice

Yes…white rice, but only when cooled or eaten with vinegar:

• Increases resistant starch
• Lowers glycemic response
• Feeds healthy gut bacteria

Better tolerated than potatoes for many.

2. Eggs

High in protein.

Protein:
• Keeps you full
• Builds muscle
• Burns more calories during digestion

Helps reduce total calories without feeling

Everyone thinks burning fat is “calories in, calories out.”

But you can’t lose belly fat if your hormones are chronically elevated.

Here's how to burn fat correctly (according to science):

1. Stop spending so much time on cardio

Chronic cardio doesn’t burn fat.

Overtraining impairs thyroid and metabolism.

It raises cortisol, breaks down muscle, and makes your body store fat long-term.

Diet accounts for ~80% of fat loss outcomes.

If you must do cardio…

Try zone 2 cardio:

• Heart rate: 60–70% of your max
• Duration: 45–60 minutes
• Frequency: 4–6 times/week

At lower heart rates, your body uses fat for fuel.
Go too hard, and it switches to carbs.

Your brain is starving for this ONE nutrient.

It's not a vitamin, mineral, or protein.

It's a natural substance that slows aging in adults and transforms newborns' brain development forever.

Here's what it is (& how to get enough of it naturally): 🧵

It’s called Nitric Oxide (NO).

Your body makes it every day.

NO widens blood vessels and fuels cellular energy.

But by age 40, your levels drop by over 50%, which means:
• Less brain oxygen
• Slower energy
• Weaker blood flow
• Higher risk of disease

Newborns without enough NO can suffer permanent brain damage.

In hospitals, doctors give nitric oxide gas to save babies who can’t breathe.

In adults, it powers neuroplasticity (the ability to learn, adapt, and grow).

Your brain alone uses 20% of your body’s oxygen.
