Your Food Is Making You Sick

ByBryan JohnsonBlueprintNutritionLongevity

Hi friend,

Five years ago, I decided to become a scientific experiment.

  • I peed in cups
  • plucked my hair
  • ejaculated into containers
  • spit in tubes
  • ultrasounds, MRIs, oxygen tests
  • sequenced my genome
  • biopsied my skin
  • took 30,000 images of my bowels
  • collected my blood daily
  • measured my erections
  • scanned my bones
  • imaged my brain
  • quantified my lung capacity

…if it could be measured, we measured it.

We discovered my body was not one age, but hundreds of different ages. And we uncovered potentially life-threatening problems I didn't know existed.

For the prior 42 years, I had destroyed my body. I was an entrepreneur and father of three who didn't sleep. I was obese. Inflamed. My cortisol was shot. I was suicidal. Had lost my family and community.

I was on a fast track to death.

At the same time, I had just sold my company Braintree Venmo for $800 million. It was an unimaginable amount of money. The question was… what should I do with it?

This is when Blueprint was born.

A few years ago, when people were dreaming of superintelligence, I asked why we couldn't be the first generation who wouldn't die.

  • I built a team of longevity researchers and doctors
  • We examined thousands of scientific papers
  • The scientific evidence from the past 400 years
  • What keeps people alive and what leads them to die

Yes. It was possible. Behavior and consumption could dramatically extend lifespan.

So we turned it into a protocol.

The Algorithm

We spent years designing an algorithm. It dictated what I should eat, when I should sleep, how I should move, and what molecules I should consume. Every decision, determined by science and data.

Across 2,000 days, we set out to reverse the decades of damage.

I rebuilt trillions of cells that make up my body.

Telomeres…muscles…cholesterol…gene expression…bones…nervous system…brain…lungs…sleep, all improved.

My body talked to my doctors. My doctors talked to my body. I fired my mind. I let the algorithm drive.

Five years later, I'm competing for the best biomarkers in the world. Trying to become the healthiest person on the planet.

I shared everything for free.

  • my protocols
  • my data
  • how I sleep
  • how I train
  • how I eat
  • what worked
  • what failed…

The Trap

But I discovered where most people struggled: food.

Humanity's food infrastructure is a trap. It's built to make us sick. Diet-related chronic diseases account for ~60% of deaths in the U.S.

I'd tell people about the importance of extra virgin olive oil… spermidine… fisetin… luteolin…

They'd respond:

  • How much?
  • From where?
  • What if they don't have a third-party lab report?
  • Your source doesn't ship to me?
  • It's sold out…

So I built it.

Blueprint

A stack of science's best longevity molecules.

I contacted hundreds of suppliers. Asked for testing protocols. Most failed. Some lied. Some cheated. I lost hundreds of thousands of dollars when shipments came back contaminated… after they were already on the boat.

I invested millions of my own money to construct a food system that didn't exist.

Blueprint is…

People called me a grifter. Whatever. They don't get it.

What People Are Experiencing

Thousands of people now follow the same molecular and behavior protocol I do.

  • Decades-old problems, gone
  • Pounds shed
  • Energy restored
  • Sleep again possible
  • Mood lifted

Every day I get messages from people (and their loved ones), "this has changed my life."

That makes it worth it.
