Field Note: 009
You're Solving the Wrong Problem with weight-loss
Metabolic software, triple-receptor sledgehammers, flow states at COTA, and why Japan's wellness spend is flat

Five reports this week. One thread running through all of them.
We're measuring the wrong things. Or we're measuring the right things and ignoring what the numbers are actually saying. Or we're not measuring at all and just hoping.
The Longevity Report names the upstream variable in the obesity crisis that nobody in the weight loss industry wants to touch... because touching it would put them out of business.
The Frontier Biology report asks the question that isn't being asked about retatrutide: skinny compared to what? The Adventure Performance dispatch takes you inside a GT3 at COTA and shows you exactly what a nervous system correction looks like in real time. The
Resilience Report gives you the four-step protocol I used to flip from clench to flow at 150 mph. And the Gadget Report makes the case for why geocaching is one of the most underrated performance tools available to you right now... and it costs nothing.
Different topics. Same question underneath all of them.
What are you actually optimizing for?
Let's get into it.

Metabolic Software

Japan has McDonald's. Brutal work hours. Vending machines on every corner.
Their obesity rate is 5%.... Ours is 41%.
That's not a discipline gap. That's not a genetics story. That's what happens when a culture survives industrialization with its biological architecture intact... and ours didn't.
I made a chart overlaying U.S. and Japan obesity rates against what each country spends trying to fix the problem.
The most damning line on it isn't the obesity curve.
It's Japan's wellness spending. Flat. For 65 years. They didn't need the industry because they never built the problem.
America spent $70B/year on weight loss by 2010. Obesity hit 36%.
By 2020 we spent $80B+. Obesity hit 42%.
The industry grew. The problem grew. That's not a coincidence. That's accounting.
I wrote the full breakdown in this week's Guild of the Wild field note. Eight questions. The upstream variables nobody wants to name. And the cultural framework that actually explains the flat line.

Retatrutide Is the Ultimate Longevity Paradox
Everybody's celebrating retatrutide like it's the second coming of weight loss science. Triple receptor agonist. GLP1, GIP, glucagon all at once. Visceral fat obliterated. Numbers on the scale dropping fast. And sure... if obesity is killing you, that part matters. But let's be brutally honest about what the drug is actually doing to the rest of the system. Resting heart rate goes up 5-10 beats per minute. Every 10 BPM increase in resting heart rate is independently associated with shortened lifespan. Muscle mass drops, and muscle is the single best predictor of longevity we have. Sleep fractures. Sodium tanks. The nervous system runs in a low-grade fight-or-flight loop all night. These aren't minor inconveniences. These are direct hits to every pillar we know extends life.
Doctors are so hypnotized by the number on the scale that they've stopped asking the obvious question: skinny compared to what? Compared to the person with lower visceral fat but no lean muscle mass, fragmented sleep, a heart beating 10 beats harder than it should, and sulfur burps so bad they're throwing up food they ate three days ago? That's not metabolic optimization. That's trading one disease for a cluster of others we're not measuring yet. The weight loss is real. The cost accounting isn't happening.
The people using retatrutide aren't stupid. They're desperate. And the system that got them there failed them first. But the answer to decades of metabolic neglect isn't a triple receptor sledgehammer with zero FDA oversight purchased off the internet because Reddit told them to. The answer is building the actual engine: muscle, sleep, sodium balance, heart rate variability, longitudinal data. Those aren't sexy. They don't drop 40 pounds in 6 months. But they also don't quietly dismantle every longevity marker you have while making you look better in photos. There's a difference between losing weight and gaining health... and right now, almost nobody in this conversation is making it.

The Day My Spine Melted Into a Seat at COTA

I showed up early. Too early. Nobody was there yet, and the breakfast I was counting on? No dice.
So I stood there with a coffee I normally skip... because caffeine gives me that unregulated feeling I can't stand. The jittery, out-of-control hum that makes my nervous system feel like a radio station between channels. I had it that morning. Full blast.
Then Danny Soufi walked up.
Hopping into that car, the first half of the lap hit me like a freight train to the chest. Sweat. Immediate. My mind bolted in every wrong direction at once. My body clenched. Every muscle fiber turned to steel. This is what it feels like when your nervous system goes full red alert... and you're a passenger.
I hate being a passenger. Being a passenger means I'm not driving. And when I'm not driving, my brain invents every possible catastrophic scenario and runs them all simultaneously at 150 mph.
But something shifted halfway around that first lap.
I caught myself. I said my statements. I put my game face on.
And just like that... my whole nervous system corrected.
This is the moment I want you to understand, because it's the real story. Not the G-forces. Not the speed. The moment I chose to flip the switch.
I entered flow.
That all-familiar place I love to live but hadn't visited in a while. The place where your body stops fighting the environment and becomes part of it. Where your mind stops narrating and starts participating. Where everything goes quiet inside even as everything screams outside.
My permanent smile kicked in.
My body became one with the car and the track. I could immediately imagine myself behind the wheel of that rocket ship... because I wasn't just riding anymore. I was IN it. Fully. Deeply. The fear had been replaced by something that felt like coming home.
I kept giving Danny the thumbs up. Go faster.
And he noticed. Because that's what a great driver reads... not the speedometer, but the human beside him. He saw I was relaxed. He really picked up the pace. We passed everyone on the track. We were tapping the absolute limits of the car... drifting, sliding around corners, dancing on the edge of what rubber and road will allow before they stop agreeing with each other.
I felt free. I felt like myself.

How do you get into your flow
Here's what most people don't understand about flow: it isn't the absence of fear. It's what happens when you stop fighting the fear and start moving through it.
Your nervous system doesn't care if you're in a GT3 at COTA or sitting in a high-stakes board meeting or dropping into cold water at 5am. The physiology is identical. The red alert fires the same way. The body clenches the same way. The mind sprints in the wrong direction the same way.
The difference between people who access flow and people who stay stuck in the clench... is one thing.
They have a protocol.
Mine took seconds. Statements I've trained myself to reach for. A game face I've worn enough times to know exactly how it feels to put on. A body I've practiced correcting under pressure until the correction became automatic.
Here's the framework:
Step 1: Name the state. Don't pretend you're not nervous. My hands were sweating. My body was clenched. I named it. "I'm activated." Not scared. Activated. This reframe matters more than it sounds.
Step 2: Remind yourself what's real. Halfway through that lap I had one clear thought: I am safe. Not "probably safe." Not "statistically unlikely to die." Safe. Chosen. Here. Present. I made myself feel that truth physically... not just think it.
Step 3: Give your nervous system a direction. Fear is energy without a target. Flow is energy WITH a target. The second I stopped resisting the speed and started tracking it... leaning into the physics, reading the corners, watching Danny's hands... the activation became fuel instead of friction.
Step 4: Thumbs up. This one is simple. When you're ready to go deeper, signal it. To yourself. To whoever's driving. To the situation. More. I'm ready for more. Most people never give themselves permission to say that.
Flow isn't a destination. It's a skill. And like every skill I've ever built... it requires you to be willing to clench, correct, and commit.
I've had 14 broken bones. I've run 44 miles in the desert until heat exhaustion stopped me. I've lived in a bus with my family for a year and rebuilt my health from a calcium shell disease most doctors had never seen.
And I'll tell you the truth... it's actually hard to get me nervous at this level anymore. Not because I'm fearless. Because I've practiced the protocol enough that the gap between fear and flow has gotten very, very small.
You can close that gap too.
The track is waiting.

Geocaching: The World's Biggest Treasure Hunt
There are 3 million hidden caches sitting right now within a few miles of where you're reading this.
Most people have no idea.
Geocaching is GPS-guided treasure hunting. Someone hides a container. Posts the coordinates. You find it. Simple concept. Wildly addictive once you start.
I take my kids out and watch something happen that no screen has ever produced. They're navigating. Problem-solving. Reading terrain. Moving through nature with a actual mission... not just "go play outside."
But here's what most people miss when they write this off as a family activity.
The benefits go much deeper than a fun Saturday.
Nature exposure (what the Japanese call Shinrin-yoku) reduces cortisol, lowers blood pressure, and measurably shifts your nervous system out of fight-or-flight. You don't need a spa. You need trees and a reason to walk through them.
Non-linear movement across uneven terrain activates stabilizer muscles, proprioception, and coordination patterns that a treadmill will never touch. Your body was built for this terrain. It remembers.
Purposeful outdoor time changes the psychology of exercise entirely. You're not working out. You're hunting. The dopamine hit when you find the cache is real... and it keeps you out there longer than any fitness app ever will.
And the social piece? You're actually talking to your kids. No headphones. No notifications. Just navigation, mud, and a shared mission.
This is what movement is supposed to feel like.
Go find something!!!
Go find your edge. That's where resilience lives.
