Review

Wall Street Journal bestseller
Publisher's Weekly bestseller
One of CNET's best new health and wellness books to read in 2020

"The book you are holding contains the most up to date, cutting edge information on health and fitness. Ben has devoted his life to researching and testing every modality of human performance excellence. His curiosity is boundless and we are the beneficiaries of his tireless dedication to the newest data on sleep, diet, exercise, supplementation and biohacking."
-Rick Rubin

"In today's fitness space, self-experimentation is the name of the game. In this crowd, few are pushing things further than Ben Greenfield."
-outsideonline.com


"Ben has always been at the bleeding edge of health and fitness but in Boundless he takes the newest and best information and synthesizes it to address all aspects of performance, health and longevity."
-Robb Wolf, New York Times bestselling author

"Boundless means living without limits and this book will show you how. If you are looking for limitless energy, health and how to live your best life, this book is for you."

-J.J Virgin, New York Times bestselling author

"Ben Greenfield masterfully combines science, practical experience, recipes for life, and entertaining stories of his extreme experiments to produce an epic book that is inspiring, informative, and life-changing."
-Mark Divine, Founder, President & CEO at Unbeatable Mind & SEALFIT

"No one does a deep dive into human health and performance like Ben Greenfield. He leaves no stone unturned as he explores all the recent (and ancient) science surrounding optimal health. No matter where you are on your longevity journey, there are many concepts in this book that, if implemented, will likely change your life for the better."

-Mark Sisson, New York Times bestselling author and founder of the Primal Blueprint and Primal Kitchen

"As someone who has always had a hard time sleeping, I'm grateful for Ben's willingness to be his own case study. I learned so much and will be incorporating some of his suggestions in my sleep life. No one has the time to drill down and get as granular on important self care techniques, but Ben and his new book
Boundless provide very detailed solutions that are thankfully spelled out and comprehensive."

-Gabby Reece, American professional volleyball player, sports announcer, fashion model and actress
"Pacific College's Master of Health and Human Performance degree was inspired by the state-of-the-art health information presented in Ben Greenfield's podcasts. Our faculty were so pleased to learn that many of these ideas and insights were being published in his book, Boundless. The book and its accompanying Book Resources website are tremendous resources, particularly for our program's Nutrition and Physiology of Human Performance courses. Selecting Boundless as a text was an easy decision. Its contents challenge many conventions while expanding our boundaries. It is therefore a perfect vehicle to develop the critical thinking and evidence-informed practice of our graduate students."

-Jack Miller, President at Pacific College of Health and Science

The Biohacking Bible
5 out of 5 stars
The Biohacking Bible
This is a Masterpiece. I refer to is as the “Biohacking Bible”. Ben Greenfield did a great job on putting all his years of research and self-experimentation together, this is a book that will serve doctors, nurses and anyone else in the medical fields, it also serves curious readers like myself that are getting into the world of Biohacking. This is not a book that you have to read from cover to cover, you can read the chapter that’s most relevant to what you’re working on in your personal life or whatever you would like to dive deeper into. From fixing a leaky brain, hacking sleep, optimizing sex, optimizing your immune systems, recovering at the speed of Wolverine, smart drugs, nutrition, exercise, looking beautiful, living a long life, and personal fitness, this book has everything we need to become Boundless. I honestly believe if this book was published a few years ago, I would’ve been able to help extend my mother’s lifespan. She passed away at age 55 from Breast Cancer. That’s how powerful this book is, it has the ability to save peoples lives and help us live our best life’s in our physical bodies. I recently got into a car accident, so Chapter 12 has been really helpful for me as I recover from those injuries, also Chapter 7 on sleep has helped me better my quality of sleep and reduce insomnia symptoms. I am a student of Ben Greenfield, I took his 7 week program “The Longevity Blueprint” that he put together with Mindvalley. This book complements everything I learned on that program and expands on everything I heard about on podcast and blogs. Thanks to this amazing piece of world, now I’m able to have intelligent conversations with my girlfriend, who’s going to medical 🏥 school. Thank you Ben Greenfield for experiment on yourself and spreading your discoveries to better humanity.
Thank you for your feedback

    Ben clearly does his homework. This book is so thorough and well researched. He covers from beginner to advanced biohacking with suggested attainable first steps. I do wish he had purchase links the product recommendations, rather than having to research that on my own because I trust his opinion and know that he’s tested what he is recommending. With all the noise in the biohacking industry right now, Ben feels like an authentic voice that I can trust.

  • Reviewed in the United States on April 11, 2020
    Format: HardcoverVerified Purchase
    I read this book from cover to cover. Here's why it's brilliant and why the negative reviews are misguided.

    1. The book is clearly the result of a lifetime of research into health, fitness, and well-being. It covers a range of topics, and it weaves together a big-picture perspective with a nuanced account of physical processes. For example, you'll learn about how the body deals with digestion generally (big picture) and *why* specific practices like extended fasts can be helpful for weight loss (nuance). This, by the way, is really hard to do - most health books will give you the big picture, which is interesting but doesn't help you operationalize the knowledge, or the nuance, which gives you a laundry list of tips without a holistic explanation of why they are effective. Negative reviewers complain that it's long - um.... yeah, he's covering every single topic related to the body, what did you expect? This is specifically designed to be a live-with-it, learn-with-it, read-what-you-need type of book. If you were expecting a weekend read, then you didn't do any research into the design or intent of this book.

    2. The book combines peer-reviewed scholarship with the author's experience as a fitness coach. I'm a college professor, and the negative reviews related to the use of scholarship are completely absurd. The studies he mentions are behind a paywall, yes - academic publishing is an industry, and the vast majority of studies are behind paywalls - welcome to the marketplace. The studies he mentions are not in footnotes, yes - this is not a university-press-style textbook, it's a synthesis, so the standards of citation are entirely different. If he did include the footnotes, people would complain that the book is too much of a textbook. The studies he mentions have not been duplicated, yes - this is a major problem *in the sciences as a whole*. Again, the author is not responsible for problems proper to academic research - problems about which most of the negative reviewers, with all due respect, know nothing.

    3. The book spans the conventional and the unconventional. There are really compelling pieces of advice here - pieces of advice that are embedded within a broader framework of health and fitness. Negative reviewers claim the advice is weird, and then complain that the advice is obvious - ok, which is it? It's an invalid critique, because the author always begins with more established, well-studied methods and then moves onto less established, cutting-edge methods. This is a good thing - we want to understand both the orthodox and the avant-garde. Again, it is rare to find a book that offers both - you typically find orthodoxy in textbooks and experiments in biohacking publications.

    4. The book is extremely well-organized. I write for a living, so I'm hyper-aware of how a book is structured, how it flows from topic to topic, and how it positions the reader. The author begins with a big-picture explanation, then moves onto operational practices; from there, he begins with conventional/accessible practices and then moves onto experimental/niche practices. Readers also have the choice of reading one chapter at a time, out of order, which makes the book very compelling - follow your interest and hop around between topics - the print version of surfing the web. I jumped around before deciding to read it from cover to cover.

    5. The book has heart and personality. Through jokes and anecdotes, the author ensures that this does not read like a textbook. It's playful, which is necessary if one is not to take oneself too seriously. Some of the negative reviewers took issue with the tone - I would much prefer to feel the presence of the author than to read a dry textbook.

    All in all, the book is a masterwork on health and fitness. It is well-researched and well-structured. It is playful and pleasurable to read. At the heart of the typical negative review is a fundamental misunderstanding of scientific study, book composition, and authorial tone. At the heart of the book is a lifetime of research into health and fitness, a spirit of inquiry and play, and a sense of empowerment that you can feel energized, strong, and, indeed, boundless.

    I'll begin with the fact that people who are interested in open their mind to new aspects, subjects in life - getting books like Boundless.
    I've learned a lot from people like Ben, but my interest started way before with Tim Ferriss. He changed my thinking, my view on health and raise my interest on studies and the world of biology and biochemistry.
    These people literally changed my life, got me out of depression, and got me to the best physical and mental health I've never been at.

    Books like Boundless have impact on people, and if stuff Tokolosh called "Magical thinking" and Pseudo, eventually lands on people who are curious, and they, like myself - will never stop with Ben, but will take is further and search for themselves, be interested in amazing personal like Rhonda Patrick, and develop the urge to talk about these subjects so more of those subjects will reach everyday conversations.

    About the actual comment of Tokolosh, it's very vague, vain and niche to VERY SPECIFIC POINTS in this HUGE book. If feels very narrow-minded, and self-centered thinking.
    People are not very smart, OR interested in looking for the references by themselves.
    Some, will dig deep to know more.
    The point of this book, as many others, is to get people like Tokolosh, others, and myself - more open minded to way more ideas than what everyone stick onto.

    It is correct that it is HUGE.
    HUGE as Ben's mind.
    But it seems Tokolosh judge a book by it's cover.

    Let's start by the fact that there are MANY good information other than Tokolosh's hair-splitting points.
    For example - like the Navy SEAL's breathing technique as an example, which REALLY helps me to take a long run EASILY.

    He saves the references online, and he also said so in his intro, and/or newsletter or his podcasts which Tokolosh probably don't listen to. Ben has definitely said it somewhere.

    This probability explains Tokolosh's - Bad jokes - point.
    People who love listening to Ben - got to know his old-timely humor, not judging by those people's level - but by their connection to his personality.

    Which takes me to the point where Ben's knowledge is richer than you, me and Tokolosh together, meaning he actually took his time writing this book, looking into every reference he had.
    I trust his skill of researching.
    Referring to Tokolosh's point on the turmeric amounts - its referring to different results. Not "one subject".

    Everything else Tokolosh has said - which I got really bored because it got too long :) - is like copy-pasting the general ideas of 90% of the world's population.

    Homeopathic approach for example - is mostly placebo based - and placebo helped MANY. PEOPLE. around the globe.

    And the judging a book by its cover as I mentioned in the second line of my reply - WHO SERIOUSLY WRITES A REVIEW ON THE BOOK'S COLORS?? who cares? This is pure hair-splitting Ben on irrelevant stuff.

    And Ben - I'm not a huge fan, but I'm good in understanding one's ideas and purpose.
    You've gone to great lengths building your knowledge, body and this book is a huge result.
    Keep up the great work.

    David.

    5.0 out of 5 stars Excellent & Comprehensive treasure trove of information

    This book is a gold mine of information for anyone who wishes to improve their health and well being. Covering all aspects, from fitness to extensive dietary and nutritional recommendations. Even many aspect of Biohacking, utilizing technological means are covered thoroughly. The material in this book can positively transform anyone who applies the principles contained within the pages.
    If I have any criticism at all, it would be for the audiobook version (I purchased both the hardcover and audiobook versions). The narrator frequently does not use the proper pronunciation of various medical terms and often has long pauses, due to unfamiliarity with the words that follow next (this would have been a simple fix in editing). If you have listened to Ben Greenfield himself speak on these topics, he is very well spoken, so the slight mishaps are entirely on the shoulders of the audiobook narrator. Still, despite these minor peeves, the content is so valuable, that I easily overlook any minutia, that may irk me personally.
    I cannot speak favourably enough about this tome of health - it covered literally all aspects, leaving no stone unturned in the quest for optimal physiological function and the zenith of wellness.

    5.0 out of 5 stars The MOST COMPREHENSIVE book on Health and Longevity
    Reviewed in the United Kingdom on January 26, 2020
    Format: HardcoverVerified Purchase
    There is lots of science nowadays showing the great ways you can improve your health and longevity. Lots of books, some focusing on specifics like brain health, to eating and others on exercise. So many podcasts also available and there is lots of great content and great breakthroughs in biohacking that can transform your health. It is tough though given the amount of information and also the differences in opinion.

    I have been listening to Ben's podcast and also did one of his courses with Mindvalley and I really trust his opinions. If you haven't listened to his podcast, I highly recommend it but you don't need to, to make the most of this book.

    Ben has produced the most comprehensive book I have ever come across on this subject and what's more if you thought the massive 640 pages was lots, it has further additional information available online to complement what is on the book. Apparently there was over 1200 pages of content but of course, they did have to cut down the size of the book. If you are thinking the book is expensive, the price actually reflects how large it is and sheer content there is in this. You would have more than 3 books of information within that book easily plus it has colour and looks really good on the coffee table.

    However, the size of the book is not an issue as you don't need to read this from cover to cover. If you click on the image of the book on this page just below where it says Look inside, you can get a good sense of what the book will be covering. Ben also recommends in the book that you can dip into any of the chapters you want based on your need so there is no need to get overwhelmed with needing to read a massive book and understand it before you can do anything with it.

    There are 21 chapters in the book which cover themes around your brain, stress, eating for the brain (food, supplements, nootropics, biohacking gear), sleep, fat burning, muscle building, recovering (and biohacking gear for this as well), healing your gut, nutrition, immune system, how to test and track your health, sex, longevity, different diets and also how the environment can be hacked to improve your health.

    Each chapter is very comprehensive, Ben has made the language simple and easy to understand and what I really love about the book is that it has colour and lots of useful pictures as well to help you understand key concepts e.g. Stretches and exercises have illustrations which are very useful and there are summary tables as well.

    Each chapter ends with a summary called The Last Word. This simplifies and summarises what has been discussed in the chapter and then it finishes off with a section - One Thing You Can Do This Week. I really like this as it moves the focus to application and allows you to do something with what you have learnt. The book really helps you to start putting in place action and doing something to improve your health.

    If you want a deeper dive into any of the topics then at the end of each chapter you will be able to look at resources on the website which also include links to podcasts, recommended tools, supplements, references, videos and much more.

    The only disadvantage this book has is its size. This is a massive book. It is more than double the size of a typical hardback. So the size and weight mean it is not a portable book you can carry around while travelling to read though you could use it for exercise on the move. It is about 2.5 Kgs! I have included some pictures for comparison.

    I read Super Humans by Dave Asprey some time back and also been reading Lifespan by David Sinclair and Brain Wash by David Perlmutter. Health is a very important priority for me this year and this decade and I know Boundless is going to be a key resource to support me with this.

    If you are looking to navigate this complex world to improve your health and one resource that will support you in doing this then get this book. It is a game-changer and can really help you understand how to improve your health, whether you are a complete newbie or a seasoned biohacker.

    O livro é muito extenso, mas vale a pena por cada página lida, além de trazer uma quantidade enorme de material em sites, livros e publicações recomendadas.
