What happens when you rebrand basic health advice with the word "biohacking" and slap a 90-day plan on it?
I was prepping slides for a client pitch at midnight - one of those nights where caffeine stopped working two hours ago but the deck still needed three more sections - and I figured I'd let Ben Angel's Unstoppable ride in the background. The premise hooked me: bestselling author hits rock bottom with fatigue and depression, reverse-engineers his way out through nootropics, wearable tech, and neuroscience. That's a story I want to hear. My mom ran a dry cleaning business on four hours of sleep for twenty years. She didn't call it biohacking. She called it Tuesday.
The 90-Day Plan That's Really a 90-Minute Plan
Bottom line: there are about 45 minutes of genuinely useful content in this 8-hour audiobook. The section on nootropics - where Angel walks through six specific cognitive enhancers and his personal experience testing them - is worth your time. His framework for identifying seven triggers behind brain fog is practical enough that I actually paused my deck to jot down notes. But then you get advice like "don't drink coffee late" and "reduce your screen time at night" delivered with the gravity of a TED Talk revelation, and I'm wondering who the target audience actually is. One listener nailed it: they expected advanced tips and got told to stop watching TV and scrolling social media. This is what my parents did instinctively. Now it has a TED talk.
The progressive overload concept - borrowed from strength training and applied to mental performance - is the strongest structural idea in the book. Angel argues you should incrementally push your cognitive limits the way you'd add weight to a barbell. Fine. Good metaphor. But he takes an idea that deserves a tight chapter and stretches it across multiple sections with repetitive anecdotes. I've seen this approach fail at three different companies I've consulted for: take one sharp insight, dilute it with motivational filler until nobody remembers the original point.
Ben Angel vs. The Biohacking Genre
Here's where it gets interesting - or frustrating, depending on your baseline. If you've already read Dave Asprey's Head Strong or listened to anything from Huberman, this book is remedial. Angel name-drops Asprey (who apparently contributes to the book), but the depth doesn't come close. It reads like Biohacking 101 for people who just discovered that sleep affects cognition. Which - look, that's a valid audience. Not everyone grew up watching their parents grind through exhaustion as a lifestyle. Some people genuinely need someone to tell them that nutrition affects their mood.
But the title is Unstoppable, not A Gentle Introduction to Taking Better Care of Yourself. The marketing promises world-leading biohackers and neuroscientists. What you mostly get is Angel's personal narrative with some expert quotes sprinkled in for credibility. A memoir can carry a whole book on one honest voice - The Reason I Jump never needed a parade of expert cameos - but the story has to earn its runtime. The "align your biochemistry with your soul's purpose in three easy steps" bit made me physically wince. My 2.0x speed couldn't save this one from the motivational fluff sections.
Gary Tiedemann Does His Job (and Not Much More)
Gary Tiedemann narrates with professional clarity. Clean audio, steady pacing, no weird pronunciation issues. He's competent the way a Honda Civic is competent - gets you where you need to go, nobody's writing poetry about it. I got the same impression from his work on Supremacy License - reliable output, limited upside, exactly what the spec sheet promised. For a nonfiction business-adjacent book, that's honestly fine. You don't need vocal fireworks for a chapter about breathing techniques. But there's zero personality in the delivery, which means when Angel's writing dips into motivational-speaker territory, there's nothing in the narration to elevate it or add texture. It just... lands flat.
Who Gets ROI Here (and Who Doesn't)
If you're brand new to biohacking, never read a book on cognitive performance, and need someone to hold your hand through the basics with a personal story attached - this will genuinely help you. No shade. Everyone starts somewhere.
If you've read more than two books in this space, or if you've ever spent 20 minutes on a biohacking subreddit, skip to chapter 5 for the nootropics overview and call it a day. Thank me later. The assessment tool Angel mentions could add value, but in audiobook format you're directed to go online for it anyway, which somewhat defeats the purpose.
Jenny would say I'm being harsh. Jenny is right. But I'm also right that a book promising to help you "become unstoppable" shouldn't include advice your doctor gave you at your last annual physical. The key takeaway is worth the listen. The other 7 hours? Not so much.
