I Optimized Myself Into Misery (And Every Pleasure Disappeared)

I turned my entire life into an Alzheimer's prevention protocol. It nearly broke me.

Key takeaways · TL;DR

Dr. Kevin Tran, an APOE4/4 carrier, optimized his life so aggressively for Alzheimer prevention that guilt ate into every pleasure. His solution is the 90/10 rule: keep a rock-solid baseline routine for 90 percent of the time and allow conscious, guilt-free deviation for the other 10 percent. Sustainable 90 percent consistency beats perfect 100 percent burnout.

Definition

A sustainability framework where 90 percent of time follows an optimized routine and 10 percent allows conscious, guilt-free deviation.

The rule prioritizes long-term consistency over short-term perfection. It prevents burnout and protects psychological well-being while still delivering the majority of the preventive benefit.

Hi Phoenix friend,

I know we keep talking about interventions here. Diet, exercise, medical devices, supplements…
And I know it ends up becoming overwhelming because we always think: am I doing enough…when there is so much to do?

So this post is different.
Because there's something nobody talks about in the longevity / Alzheimer’s space.
You can optimize yourself into misery. And rob yourself of all of life’s joy.

I know because I did it.

The Guilt Spiral

Here's what happened to me. After I discovered I carry two copies of APOE4. I went all in. - Every meal became a calculation (saturated fat, calories..).
- Every activity became an optimization choice.
- Every night out (drinking) became a negotiation with my own brain.

And slowly, without realizing it, my entire life reorganized itself around one goal: reducing Alzheimer's risk.

What I eat? Only what's good for my brain.
My activities? 15 hours a week of exercise I don't particularly enjoy (do people actually enjoy HIIT workouts?).
My social life? Dull, because alcohol is bad for our brain and sleep.
Even my work became Phoenix. Everything. All of it. Pointed at one thing.

Here's the cruel irony. All of life's greatest pleasures happen to be terrible for our brain somehow (at least for me).

I love sweet pastries. I love cheese. I love wine. I love staying up late.
Some of the best nights of my life were fueled by alcohol (and bad decisions).
Some of my most meaningful relationships were born from going out, staying up too late, and doing things that zero longevity experts would approve of.

But the worst part wasn't giving those things up.

The worst part was the guilt.

I'd look at a pastry / cheese/ ribeye and instantly my brain would fire up: saturated fat, insulin spike…
I'd have a glass of wine and think about neuroinflammation.
I'd stay out past 10pm or eat dinner late and calculate the damage to my sleep architecture.

The guilt ate into the pleasure. And one by one, the pleasures disappeared. Even when I "allowed" myself something, there was always that little pinch. That voice saying "this is bad for you."

That's not living. That's just surviving with extra steps.

The 90/10 Rule

So here's what I figured out (and honestly, it took me longer than it should have).

We can't be perfect. We shouldn't try to be.

My solution is simple. Have a rock solid baseline routine, truly optimized, where you know you're doing your best. And then consciously allow yourself 10% deviation. No guilt. No mental math. Just living.

For me, that deviation is geographic. I travel a lot between San Francisco, Paris, and Singapore. In those home cities, my routine is dialed in. Sleep, nutrition, exercise, supplements. Everything locked.

But when I travel for pleasure? All bets are off.

Milan? Pizza, gelato, pasta, wine, late nights.
Japan? Ramen all the way.
China? Every dumpling and noodle spots I can find.
Mexico? Tacos every day.

I go full send because the food is genuinely better in those places anyway (the pleasure per calorie is way higher), and these are exceptional moments that deserve to be lived fully.

Over a year, maybe 10% of my time is "off protocol." And that's completely fine.

We've talked to members who do it differently in our new Phoenix Member Stories (available on my Youtube channel).
Some allow deviations during family gatherings (Thanksgiving with the kids is not the time to count macros). Some during celebrations. Some during specific events that are clearly defined.
The common thread? It's conscious. It's bounded. And it's guilt free.

Because here's the math that actually matters. Being 90% consistent forever beats being 100% perfect for three months and then burning out completely. Going from 100 to 0 is way worse than cruising at 90.

Be Kind With Yourself

Now, a word for those of you reading this newsletter and feeling overwhelmed.

I get it.

Every week there's a new study. A new supplement. A new protocol. A new thing you "should" be doing. It can feel like you're never doing enough. Like there's always one more intervention between you and safety.

Stop.

Take a breath.

You are already here. You are reading this. You are taking action. You are part of this community. That alone puts you miles ahead of the vast majority of people (including most APOE4 carriers who don't even know their status, let alone do anything about it).

You are already dramatically reducing your risk just by showing up.

So here's what I want you to do. Pick the interventions that feel sustainable for you. Not all of them. The ones you can actually stick with. Build your routine one piece at a time. Stack habits slowly. Don't try to overhaul your entire life in a week.

Something my psychologist used to tell me (and it took me way too long to listen): be kind with yourself.

This is a marathon. Decades long. The goal isn't perfection. The goal is consistency. The goal is building something you can maintain for the rest of your life while still actually enjoying that life.

Because what's the point of adding years to your life if you've removed all the life from your years?

With love,

Kevin

FAQ

Frequently asked questions.

Can an APOE4 prevention protocol become too strict?
Yes. Dr. Kevin Tran describes optimizing his entire life around Alzheimer prevention after discovering he carries two copies of APOE4. Every meal became a calculation, every social occasion became a negotiation with his brain, and his work life collapsed into Phoenix. The problem was not giving things up but the relentless guilt that ate into any pleasure he did allow himself. Over time he concluded that an overly strict protocol is not living, it is surviving with extra steps, and it risks causing its own kind of harm.
What is the 90/10 rule for APOE4 carriers?
The 90/10 rule means maintaining a rock-solid, fully optimized baseline routine roughly 90 percent of the time and consciously allowing 10 percent deviation without guilt or mental math. The deviation can be geographic, tied to travel or specific places, or bound to specific events like family gatherings, celebrations, or cultural experiences. The key is that deviations are conscious, bounded, and guilt-free. Being 90 percent consistent for life delivers more benefit than being 100 percent perfect for three months before burning out completely.
How does guilt affect APOE4 prevention efforts?
Guilt is corrosive. Dr. Tran describes how even when he allowed himself a pastry, cheese, or wine, an internal voice would calculate saturated fat, insulin spikes, and neuroinflammation, ruining the pleasure. One by one the joys of life disappeared, not because they were eliminated but because they were no longer enjoyable. Guilt adds a psychological tax that undermines the sustainability of any long-term protocol, which is why bounded, guilt-free deviations are so important.
What should overwhelmed APOE4 carriers do?
Dr. Tran advises stopping, taking a breath, and recognizing that simply being informed and engaged already puts you ahead of most APOE4 carriers who do not know their status. Pick only the interventions that feel sustainable for you rather than trying to adopt everything at once. Stack habits slowly. Be kind with yourself. The goal is decades-long consistency, not short-term perfection. Sustainability and psychological well-being are themselves protective because chronic stress and depression accelerate cognitive decline.
Is it okay for APOE4 carriers to enjoy food and travel?
Yes, within a bounded framework. Dr. Tran travels between San Francisco, Paris, and Singapore with a dialed-in routine, but when traveling for pleasure to Milan, Japan, China, or Mexico, he goes full send on the local cuisine without guilt. He calls this the pleasure per calorie trade-off: these are exceptional moments that deserve to be lived fully, and over a year they represent maybe 10 percent of his time. The broader principle: what is the point of adding years to your life if you remove all the life from those years?
