From the creator of Bulletproof Coffee and author of the bestselling The Bulletproof Diet comes a revolutionary plan to upgrade your brainpower—in two weeks or less.

For the last decade, Silicon Valley entrepreneur Dave Asprey has worked with world-renowned doctors and scientists to uncover the latest, most innovative methods for making humans perform better—a process known as "biohacking." In his first book, The Bulletproof Diet, he shared his biohacking tips for taking control of your own biology. Now, in Head Strong, Asprey shows readers how to biohack their way to a sharper, smarter, faster, more resilient brain.

Imagine feeling like your mind is operating at its clearest and sharpest, and being able—possibly for the first time in your life—to do more in less time? What it suddenly became easier to do the very hardest things you do? Or if you could feel 100% confident about your intellect, and never again fear being the person in the room who just isn’t smart enough, or can’t remember something important? How would you treat people if the mood swings, short temper, and food cravings that disrupt your day could simply disappear?

In Head Strong, Asprey shows us that all of this is possible—and more. Using his simple lifestyle modifications (or "hacks") to take advantage of how the structure of your brain works, readers will learn how to take their mental performance to the next level. Combining the latest findings in neuroscience and neurobiology with a hacker-inspired "get it done now" perspective, Asprey offers a program structured around key areas of brain performance that will help you:

  • Power the brain with exactly what it needs to perform at its best all day long
  • Eliminate the sources of "kryptonite," both nutritional and environmental, that make the brain slower.
  • Supercharge the cellular powerhouses of our brains, the mitochondria, to eliminate cravings and turn up mental focus.
  • Reverse inflammation to perform better right now, then stay sharp and energized well into your golden years.
  • Promote neuron growth to enhance processing speed and reinforce new learning—hotwiring your brain for success.

Asprey’s easy to follow, two-week program offers a detailed plan to supercharge brain performance, including: which foods to eat and which ones to avoid, how to incorporate the right kinds of physical activity into your day, a detox protocol for your home and body; meditation and breathing for performance, recommended brain-boosting supplements; and how to adjust the lighting in your home and work space to give your brain the quality light it thrives on.

A better brain—and a happier, easier, more productive life—is within reach. You just need to get Head Strong.

From the Back Cover

Bulletproof Means Smarter, Faster, Happier. . . .

From the bestselling author and creator of BulletproofTM Coffee comes a revolutionary plan to upgrade your brainpower—in two weeks or less.

For the last decade, Silicon Valley entrepreneur Dave Asprey has worked with world-renowned doctors and scientists to uncover the latest, most innovative methods for enhancing mental and physical performance by taking control of his own biology—a process known as “biohacking.” In his first book, The Bulletproof Diet, Asprey shared his biohacking tips for creating a better body. Now, in Head Strong, Asprey shows readers how to biohack their way to a smarter, faster, sharper brain—in two weeks or less.

Ask yourself: How would your life and health improve if your mind were working at its full potential? You’d be able—possibly for the first time in your life—to do more in less time. Instead of experiencing fatigue, lack of focus, forgetfulness, and food cravings on a daily
basis, you would enjoy sustained energy, productivity, and mental clarity. You’d be able to accomplish even the most difficult tasks with ease and feel confident about everything you do. And instead of getting older, you’d just get better.

In Head Strong, Asprey shows that all of this—and more—is possible. Following his program, which combines the latest insights from neuroscience with a hacker-inspired focus on fast results, you will learn how to take your mental performance to the next level. The Head Strong program will help you

  • Supercharge the cellular powerhouses of your brain, the mitochondria, to enhance energy and enhance mental focus
  • Power your brain with the nutrients it needs to perform at its best all day long
  • Eliminate toxins and other sources of brain “kryptonite” that slow you down
  • Reverse inflammation to perform better right now and stay sharp well into your golden years
  • Promote neuron growth to enhance your brain’s processing speed and hot-wire you for success

A better brain—and a happier, more productive life—is within reach. It’s time to get Head Strong.

Full content visible, double tap to read brief content.

Dave Asprey is the "Father of Biohacking" and founder of Bulletproof 360, Inc. He is a four-time New York Times bestselling author, host of the Webby award-winning podcast Bulletproof Radio, and the creator of the global phenomenon Bulletproof Coffee and the Bulletproof Diet.

As an overweight, overworked, and unhealthy Silicon Valley entrepreneur, Dave found himself with a dire decision to make - get a healthy mind, body, and spirit, or live a much shorter life span. Dave chose to not only live but to thrive and share that knowledge with his community. He has spent the past two and a half decades scouring the planet from Tibet to the Andes discovering and engineering ways to fully realize human potential. Transforming himself into a super high-performing human being, the experience and knowledge gained was too valuable not to share.

Through the Bulletproof Diet, countless biological experiments, and simple life "hacks", Dave has maintained a 100-pound weight loss, upgraded his brain, and transformed himself into a happy and gratitude-filled husband, father, writer, executive, and human being. With over 200 million downloads of his Human Upgrade podcast, millions of monthly unique visitors to the Dave Asprey blog, and of course the Bulletproof 360 products in millions of households worldwide, Dave has created a movement that shows us the power of intention and the limitless possibility of the human spirit and incredible capacity of the physical body.

Being Bulletproof is the state of high performance, where you take control of your biology and your environment. Dave shares his journey of self-discovery as an example that can lead you towards unlocking your full birthright potential.

Excellent book!
5 out of 5 stars
Excellent book!
I'm a little biased because I already follow Daves diet plan but I'm not a fanatic and I often disagree with Daves assertions about things. Having said that, what Dave always does and does very well is citing his sources and exact studies that he has extrapolated his views from. So many people don't do that well and make it impossible for you to read or find the exact study to form your own opinion but not Dave. The advice is sound and for someone looking to gain an edge and create a better life through better health, this book is an invaluable resource.

    5.0 out of 5 stars Important info for those with cognitive and/or any other health issues
    Reviewed in the United States on April 22, 2017
    Verified Purchase
    I've been following Dave's podcast and Facebook (and applying his advice) for a couple of years now, so I wasn't sure how much new information I'd find in this book. In fact, I ordered it mainly out of gratitude to Dave because the information he's disseminated has been largely responsible for giving me my life back. After a couple of concussions and disabling post-concussion syndrome, extreme food sensitivities, and mysterious and severe cognitive problems that had plagued me for the last decade, applying Dave's advice from Bulletproof Radio and social media posts has been THE difference between being totally debilitated and being able to function. I truly don't even want to imagine where I'd be if I hadn't discovered Dave's work by watching his TED talk two years ago.

    That being said, I was surprised and impressed at the amount of hacks and information in this book that I'd never heard before. Several bits of info he gives about how the body functions on a cellular and mitochondrial level explained patterns I'd noticed in my health that had previously been a mystery to me. I've been trying some of the hacks he presents, and have noticed a significant improvement in how I feel and function. This book finally convinced me to try two things I'd been putting off for a while. One is the Wim Hof breathing method, which Dave explains succinctly and clearly; I've been doing it every morning for a few days and I'm amazed at how much it energizes me and clears my head. The other is true Bulletproof coffee - Head Strong contains an explanation for why actually blending the butter and oil into the coffee (rather than just gently mixing it all together by hand as I usually do) makes it more effective. So this morning I broke out the blender, and blended one tablespoon each of XCT oil (I haven't graduated to Brain Octane quite yet) and pastured, cultured butter with mold-free coffee. Now I finally see why Dave's always talking about Bulletproof coffee. I feel like I can take on the whole world this morning. This is definitely my new daily breakfast.

    I found pretty much all of the information in the book extremely helpful; even the parts that were review for me were presented so well that I felt I gained a new understanding of them. Everything in this book should be common knowledge, and hopefully the book will help that happen. The book's focus on mitochondrial health makes the biohacks it contains relevant to and useful for pretty much all health problems, not just cognitive ones. Dave is a fantastic writer as well; I struggle with reading comprehension as part of my lingering post-TBI issues, but Head Strong was so coherently written and well-organized that I found it easy and quite enjoyable to read. He intersperses little jokes throughout the more technical information that keeps it light and reader-friendly, which I appreciated. The bullet points at the end of every chapter are quite useful as well. It's clear that Dave put an immense amount of effort into this book, really values the readers' time, and genuinely wants to help others live life on a higher level.

    I don't normally review books, but this one inspired me to write this lengthy and glowing review. That's how much I value it and hope it gets widely read and distributed. My sister, who has fibromyalgia but is resistant to trying anything that might improve her condition, even decided to read this book since she's heard me mention Dave's work so many times. I'm positive that applying almost anything in this book will help her. As someone who's steadily conquering my multitude of health problems one by one using the information in this book and following the Bulletproof lifestyle, I sincerely and emphatically recommend Head Strong to anyone who wants better health.

    5.0 out of 5 stars Mitochondria are to Genes what Free Will is to Predetermination

    The media could not be loaded.
    This book makes the case that optimizing your Mitochondria is the ultimate performance enhancing Biohack because your Mitochondria are the fundamental energy generation mechanism that underlie everything else.

    Mitochondria are billions of tiny, ancient bacteria that power your individual cells. You've probably heard of them before, I'll explain more in depth later what Mitochondria are but for now I think a Star Wars metaphor will suffice. In Star Wars the Jedi have their powers because of the midichlorians, which are a microscopic life form that are shared by all living things, that give the life force to all living things. That's not far off from what Mitochondria actually are!

    There's an important point I want to you to remember...

    Mitochondria are to genes what free will is to predetermination.

    This idea of Predetermination seems to be very popular, this is this idea that every molecule in your body and indeed every atom in the universe is bound by laws of physics and mathematics.

    You can often predict quiet accurately what a given atom, molecule, cell, organism, group, species, environment or even planet is going to do based upon established natural laws.
    We know, almost exactly, where Mars in going to be in 6 months.
    We know when a species is going to do their seasonal migration.
    We often know what's going to make a tumor of cancer cells grow and take over a vital organ.
    It would seem that the universe is quite predictable maybe even predetermined, with one exception, us humans.

    We seem to make some very random decisions that sometimes totally surprise everyone. From the insides of our own heads it certainly seems like we have free will doesn't it?

    We will debate back and forth with ourselves on decisions and finally go with the option that was seemingly quite unpredictable.
    Making a big decision we will write down a big list of prose vs cons to help us decide carefully between options.
    As I write this very article I make decide between the words, prose and metaphors that will best communicate the ideas my mind is refining.
    So this presents a big question, perhaps the biggest question, do we have free will or are we just playing out script that's already been written for us?

    Religion, since time immemorial, did a pretty good job at addressing this seeming paradox.
    In religion, god knows what you are going to do.

    God knows what's going to happen in the future.
    God has laid out of a path of challenges and lessons for us so that we can ultimately end of leaving this world better than we found it.
    Yet, in most religions god gives us free will or agency.

    God encourages us to be moral.
    God offers us incentives to be better people or communities but ultimately leaves the decision up to us.
    But, as many atheists have pointed out, this is on the surface a contradiction. Well, it's a contradiction that's reflective of the paradox of free will vs predetermination that profoundly confuses astrophysicists, neuroscientists, quantum physicists and social scientists and philosophers

    Here's my take on this...

    It would seem that, at scale, we have very little free will.

    Here's what I mean by this...

    When you get a statistically significant, similar group of people together you can quiet accurately predict what they are going to do. If you get a group of people with a specific IQ range you can quite accurately predict how many of them will get jobs, how much money they will make, if they will get married, have kids or go to jail. At scale, viewed as group, they have disappointingly little free will.
    Similarly, if you look at the grand course of your life, at scale, predetermined factors seem to really limit what you'll do and what you can become.
    For example; I was one of these ambitious young adults that was really determined to became a millionaire by the time I was 30 and I read a lot of books about what this was going to take and tried really hard, yet I totally failed. Now I probably have a pretty average net worth of an male, American 30 year old. Despite all my agency, I ended up quiet average.

    So even though we seem to have quiet a lot of micro-agency or free will in our short term, moment-to-moment, day to day decisions long term, at scale, you will likely end up being statistically quiet average for...

    Your sex
    Your race
    Your height
    Your attractiveness
    Your intelligence
    The social class you were born into
    These predetermined factors define almost everything about how your life is going to go.
    And what is the programming that fundamentally underlies these things?
    Your genes. More than anything else, your genes determine whether you are going to be really successful, happy or end up in jail.

    Your genes are your destiny

    This is an uncomfortable and politically incorrect truth that...

    The self help gurus won't admit to you because it undermines their transformation via positive thinking, self esteem or just be confident messaging.
    The genetic researchers and scientists won't admit to you because politically incorrect opinions can get them fired from their institutions or get their funding denied.
    Politicians certainly won't admit this to you because they sell you the illusion of free will and self determination via democracy.
    Even the companies that sell Biohacking products and Mitochondrial supplements won't admit this to you because they don't want to insult their potential customers.
    Defy your genes

    So if everyone in your family, is really successful and happy then that's a good sign that you have the kinds of genes that will lead you inevitably to become successful and happy. But if not, if your family is kind of a disaster, then it's going to take really herculean energy, discipline and motivation for you to defy your genes and resist this gravity of epigenetic trauma that is powerfully and subtly pulling you down a path of mediocrity.

    If you've ever felt like you kind of repeat the same mistakes and the same relationships and no matter how hard you try it doesn't seem like you can reach escape velocity of momentum away from the black hole that is your past then that's good sign that your genes are running your life.

    Genes vs Mitochondria

    The good news is that you can overcome your genes with your Mitochondria, sometimes in a quiet literal way, where fully functional Mitochondria allows us to overcome epigenetic trauma, it switches off vestigial defense mechanisms in our genes and psychology that don't serve us.
    And having our Mitochondria working right gives us the energy and motivation to consistently practice helpful habits because, ultimately we are what we repeatedly do.

    About Head Strong

    Like Tools of Titans by Tim Ferriss, the book is a refined version of Dave Asprey's podcast, you could learn everything in this book by just listening to the Bulletproof podcast.
    So you could of course save yourself the $12 and the 9 hours of reading by just listening to all his podcast episodes, but this book does a really great job of summarizing the best Biohacks discussed in the podcast and putting them in a holistic context of optimizing your Mitochondria. I don't recommend you buy and read every book I review, but this book I really do!

    I've been on the Bulletproof Keto diet for about 5 years now. I feel cognitively better- more clear, more focused and have a better memory than when I was younger in my twenties, thirties etc. I'm 78 years old.
    This book has new information and is helping me improve my sleep and exercise routines. Recommend this book and all his others!

    Es un anuncio mal documentado de la compañía de Dave Asprey. Básicamente te invita a a seguir una dieta cetogénica y a comprar sus productos. Está obsesionado con el moho porque tuvo problemas de chico y cree que todo lo contiene.

    Headstrong is about energy, health and vitality and how to build a life that supports more and makes more of all 3. It's the best book out there at the moment on the subject, and Dave has endangered his health at times, testing for the best methods (hacks) for all of us. Good bloke, and his supplements pack one hell of a kick too. From MCT oil to Ozone therapy, from liposomals to which lights to fit at home, it's refined, jam packed, and arguably a tad obsessive. If you did 50% of the program though, properly you would feel 100% improvement.
