Dumping Iron

Dumping Iron is the book on iron overload, ferritin and longevity by @Mangan150. Published 2016. Followed by a peer-reviewed paper in @AgingJrnl, 2021.

Iron is the "secret killer" so few health conscious people know about.

Here's how it fits into @Mangan150's unified theory of aging and disease:

My unified theory of aging and disease

Claude AI did this, using papers I selected as references. See what you think.

The Master Switch: Insulin Resistance

Facchini (2001) showed insulin resistance predicts virtually ALL age-related diseases. That's the trunk of the tree. Everything else branches from it.

What drives insulin resistance?

Kohrt (1993): belly fat, not age. Waist explains >40%, age <2%.
Blagosklonny (2006): chronic mTOR activation. Overfeeding keeps mTOR on, cells grow when they should repair.
PD's iron paper: iron accumulates with age, activates mTOR, and iron + insulin resistance are co-morbid.

What does insulin resistance cause downstream?

Khan (2017): high insulin drives high PAI-1, which drives senescent cell accumulation, shorter telomeres, faster aging. The Amish with half the PAI-1 lived 10 years longer.
DePalma (2010): high ferritin + inflammation = vascular death. Iron and insulin resistance amplify each other.
Madeo (2015): when mTOR is chronically on (from insulin resistance + iron), autophagy is suppressed. Cellular garbage accumulates. Aging accelerates.

What reverses it?

Lim (2011): type 2 diabetes reversed in ONE WEEK with caloric restriction. The damage isn't permanent.

Gibala (2020): 5 minutes of hard exercise produces the same fitness gains as 50 minutes moderate, and improves insulin sensitivity through pathways that bypass insulin entirely (GLUT4).

Fisher (2011) + Wolfe (2006): muscle is a metabolic organ that acts as a glucose sink. More muscle = more insulin sensitivity. Resistance training is the most efficient way to build it.

What's been wrong all along?

Ravnskov (2016) + Siri-Tarino (2010) + Ramsden (2016): the cholesterol/saturated fat hypothesis was wrong. Higher LDL in elderly = lower mortality. Replacing saturated fat with seed oils increased death. The medical establishment spent 50 years focused on the wrong molecule while insulin resistance was the actual killer.

PD's iron paper ties the bow: Iron is the hidden variable connecting all of it. It activates mTOR (Blagosklonny), inhibits autophagy (Madeo), worsens insulin resistance (Facchini/Kohrt), increases PAI-1 and senescence (Khan), and accumulates silently with age in every man and postmenopausal woman. The life-extending compounds (curcumin, green tea, rapamycin, exercise) all either chelate iron or inhibit the pathways iron activates.

The narrative arc for PD's content:

The medical establishment told you aging is inevitable and cholesterol will kill you. They were wrong on both counts. The real driver is insulin resistance, fueled by belly fat and silent iron accumulation, suppressing your body's cleanup systems while accelerating cellular aging. The fix isn't statins or seed oils. It's resistance training, brief intense exercise, fasting, and managing your iron. Every study points to the same conclusion: aging is a lifestyle disease, not a birthday disease.

@Mangan150’s account has been hacked. 1 million followers, so lots of potential for damage. Maybe someone at @X could assist? @Safety

PD MANGAN ACCOUNT HAS BEEN HACKED

I've attached screen shots below

The hacker changed his handle and is now impersonating an X support channel running a phishing scam

[AJAC @AJA_Cortes]

This fake X account stole @Mangan150 handle

Rebranded it

And is now running a phishing scam

[P.D. Mangan Coaching @ManganCoaching]

My main account @Mangan150 has been hacked.

Waiting to hear back from https://t.co/e7OxA5FAy2

If you get a DM from @Mangan150 or if something on the @Mangan150 timeline looks suspicious…

Please assume it’s hackers, and not me.

@Mangan150 @tferriss For many people, especially adult men, donating blood is one of those few activities that's worth allocating some time to because it's a big needle mover when it comes to managing iron levels.

The list of countries my @ManganCoaching clients live in keeps growing.

We're now at 71.

When I started this practice, I expected to coach mostly American clients, and frankly, mainly men.

But today, about 35% of my clients are women. Some solo, others as part of a couple I'm partnering with.

At the end of the day, a 55-year-old's biology in Montenegro works the same way it does in Maryland.

Whenever a potential client tells me their situation is too unique for this to work... their food culture, their travel schedule, their job stress, their family life... I point to the map.

The full list, for posterity:

NORTH AMERICA (3) Canada, Mexico, United States

SOUTH & CENTRAL AMERICA / CARIBBEAN (13) Argentina, Bahamas, Brazil, Cayman Islands, Chile, Colombia, Costa Rica, Dominican Republic, Jamaica, Nicaragua, Panama, Peru, Uruguay

EUROPE (29) Andorra, Austria, Belgium, Bulgaria, Channel Islands, Cyprus, Czechia, Denmark, Estonia, France, Germany, Ireland, Italy, Liechtenstein, Luxembourg, Montenegro, Netherlands, Norway, Poland, Portugal, Romania, Russia, Serbia, Slovenia, Spain, Sweden, Switzerland, Turkey, United Kingdom

ASIA / MIDDLE EAST (21) Brunei, China, Hong Kong, India, Iraq, Israel, Japan, Jordan, Kuwait, Lebanon, Malaysia, Pakistan, Philippines, Qatar, Saudi Arabia, Singapore, South Korea, Thailand, Timor-Leste, United Arab Emirates, Uzbekistan

AFRICA (3) Kenya, Morocco, South Africa

OCEANIA (2) Australia, New Zealand

The single most important thing you can do to reduce your cancer risk is to not smoke.

Everyone agrees on that.

The problem is most people stop there and assume the rest is luck.

[Dumping Iron @DumpingIron]

How can you tell if you should be dumping iron?

By getting your ferritin checked the same way you get your glucose levels checked.

My top 5 bare minimum health targets:

Ferritin under 100
A1C in normal range
Normal blood pressure
Waist to height ratio under .5
Triglycerides/HDL ratio under 2

Here’s why:

Iron metabolism changes are key components to the health benefits of intermittent fasting, changing in an anti-aging direction.

@ManganCoaching Lastly, here’s a very short video of me talking about iron and ferritin:

[P.D. Mangan Health and Freedom Maximalist 🇺🇸 @Mangan150]

New: Optimal ferritin levels for cardiovascular mortality reduction may range from 20 to 100 ng/ml

This is far lower than what is now considered normal; many people would have abnormal values if this were changed

I've been beating this drum for a while
