The biohacking problem

The influencers turned a science
into a supplement store.

Here's what actually happened: researchers published legitimate findings on sleep architecture, circadian biology, cold-water immersion, and metabolic flexibility. And then a bunch of people with podcasts decided that translated to a $180 red light therapy device and a branded electrolyte powder.

The science is real. The noise is not. And the noise is expensive enough that most people either go all-in on the expensive stuff or write the whole thing off. Both are wrong.

This ebook is the middle path: what the research actually says, how to apply it without buying anything, and which expensive things are actually worth it if you have the money (spoiler: most aren't).

"The most powerful biohack is also the most boring one: sleep."

Not because it's trendy. Because the research on sleep and human performance is the most consistent body of evidence in the entire field. Every other intervention sits on top of it. If you're skipping sleep to do cold plunges at 5am, you have the hierarchy backwards.

What's inside

Seven systems. No fluff.

Each chapter is built around a question: what does the actual research say, and what does that mean for someone who doesn't want to turn their life into a wellness project.

01

Sleep Architecture

What actually happens during the different sleep stages, why REM and deep sleep are not interchangeable, and the specific behaviors that destroy sleep quality without you realizing it.

02

Circadian Rhythm & Light

Your body has a clock. Modern life is waging war on it. The two interventions that actually move the needle: morning light and evening darkness. Both are free.

03

Nervous System Regulation

HRV, the autonomic nervous system, fight-or-flight vs. rest-and-digest, and why "just breathe" is actually backed by physiology — even though it sounds like wellness fluff.

04

Cold & Heat Exposure

What the cold plunge research actually shows (not what the podcasters say it shows). The dose-response curve, the mechanistic evidence, and what you can get from a cold shower at home.

05

Nutrition Without Obsession

The metabolic basics that nobody argues about. Protein, timing, blood sugar, and why the macros debate misses the most important variable: consistency over years, not perfection over weeks.

06

Movement as Medicine

VO2max and longevity, zone 2 cardio, strength training minimums, and why "just walk more" is probably the highest-ROI advice in the entire ebook.

07

Supplements: What's Real

The short, honest list of supplements with actual evidence behind them — and the long, honest list of the ones that exist because people will pay $80 for something with a clinical-sounding name.

This is for you if…

  • You've gone down the biohacking rabbit hole and need someone to separate the signal from the noise
  • You want to understand the actual science, not just the take-aways
  • You're skeptical but curious — not a true believer, not a dismisser
  • You want to optimize without making it a second job
  • You're tired of supplement ads disguised as health content

This is not for you if…

  • You want to be told your $300 supplement stack is justified
  • You're looking for a protocol to follow blindly
  • You already have your health completely dialed in
  • You want inspirational content, not mechanistic explanations
A note from Jenny

Why I wrote this
instead of a stack guide.

I spent two years being genuinely interested in this stuff — reading the actual papers, following the researchers (not the podcasters), and trying to figure out what was real. And the conclusion I kept coming back to was: the fundamentals are boring, free, and they work. The expensive stuff is mostly filling the gap for people who haven't done the boring free stuff yet.

I also spent too much money on things that turned out to not do what the marketing said. I'm not bitter about it — I learned a lot. But I didn't want to write the thing I wish I'd had earlier by padding it with things I don't believe in.

This ebook is just what I would tell a friend who asked me seriously: "what actually works?" Honest answer, no affiliate links.
