The New Book Unveiled: The 4-Hour Body (4HB)

Data crunching back to age 18. Three years of organizing self-experiments around the world. Thousands of blood tests and hundreds of case studies.

My new book is finally here: The 4-Hour Body.

I could not be happier with the end product. Truly, I am ecstatic.

If you want a minimalist guide to hacking the human body, this is it.

In each chapter (more than 50 topics total), I test everything on myself so you don’t have to. In “Reversing ‘Permanent’ Injuries,” for example, I tested the moderate options like over-the-counter supplementation and Feldenkrais, but I also imported stem-cell growth factors from Israel and had them injected. That was just for starters. The end result of that chapter? 90%+ of the injuries that plagued me for decades are now gone. I’m stronger and faster than I was at age 20.

If you want to know the two safe things out of 100 that worked abnormally well, I can tell you…

The 4-Hour Body is also designed to read unlike any diet or fitness book, which it isn’t. It’s more like a Choose-Your-Own-Adventure book for the human body, full of ridiculous stories, practical philosophies, and larger-than-life characters.

Here’s the back cover description:

THINNER, BIGGER, FASTER, STRONGER… which 150 pages will you read?

Is it possible to:

Reach your genetic potential in 6 months?

Sleep 2 hours per day and perform better than on 8 hours?

Lose more fat than a marathoner by bingeing?

Indeed, and much more. This is not just another diet and fitness book.

The 4-Hour Body is the result of an obsessive quest, spanning more than a decade, to hack the human body. It contains the collective wisdom of hundreds of elite athletes, dozens of MDs, and thousands of hours of jaw-dropping personal experimentation. From Olympic training centers to black-market laboratories, from Silicon Valley to South Africa, Tim Ferriss, the #1 New York Times bestselling author of The 4-Hour Workweek, fixated on one life-changing question:

For all things physical, what are the tiniest changes that produce the biggest results?

Thousands of tests later, this book contains the answers for both men and women.

From the gym to the bedroom, it’s all here, and it all works.

YOU WILL LEARN (in less than 30 minutes each):

– How to lose those last 5-10 pounds (or 100+ pounds) with odd combinations of food and safe chemical cocktails.

– How to prevent fat gain while bingeing (X-mas, holidays, weekends)

– How to increase fat-loss 300% using temperature manipulation

– How Tim gained 34 pounds of muscle in 28 days, without steroids, and in four hours of total gym time

– How to sleep 2 hours per day and feel fully rested

– How to produce 15-minute female orgasms

– How to triple testosterone and double sperm count

– How to go from running 5 kilometers to 50 kilometers in 12 weeks

– How to reverse permanent injuries

– How to add 150+ pounds to your lifts in 6 months

– How to pay for a beach vacation with one hospital visit

And that’s just the tip of the iceberg. There are more than 50 topics covered, all with real-world experiments, many including more than 200 test subjects.

You don’t need better genetics or more discipline. You need immediate results that compel you to continue.

That’s exactly what The 4-Hour Body delivers.

Now The Real Fun Begins

Here we go:

1) The ask

2) Big media opportunities for you

3) An offer to friends in media.


I try not to ask for too much on this blog, but today I will ask a favor: if this book sounds interesting to you, please take a moment to order it today. I’ve never worked harder on something, it’s my sophomore act, and pre-orders are critically important in the publishing world.

The book is on-sale now but will ship on December 14th. Here’s why you should pre-order now:

– You will not be charged for the book(s) until they ship in December, but ordering (really like reserving) a copy now really, really helps me.

– What would make a better X-mas gift? My dad lost more than 70 pounds using two chapters. Please consider getting a few copies for your family, loved ones, or best friends. I promise that they will not be disappointed. Ordering now means you can’t forget.

– Last but not least, your help would mean the world to me. Pre-orders will largely determine how much support retailers give this book. It’s crazy, but only hardcover sales count towards the bestseller lists. If you’ve benefited from my last book or writing on this blog, I would really appreciate your help. This has been the biggest project of my life.

The 4-Hour Body is available on Amazon,, and these online retailers.

Thank you!

Please e-mail your details and (important, if you have them) pictures to jenny.rabun-at-gmail-dot-com. No professional before-and-after pics needed, but something that shows your before and after appearance, even in normal clothes, is helpful to producers.

  1. I’m sorry, but this feels extremely sensationalistic. I’m already thrown off by some of the wording: “- How Tim gained 34 pounds of muscle in 28 days, without steroids, and in four hours of total gym time.” Does that mean four hours per week or four hours over a month with something else to supplement it? Sounds sketchy.

    I’m taking the smart consumer route. I’m not buying this book until I am able to flip through it.

  2. hi i made the pre order for the audio book and the book a few days ago…iam dieing for read this new book.i recommended 4 hourworkweek to a lot of people in argentina(135 people minimun) but only you can get it from amazon ….

    i sleep 2 hour per day but i can stay 6 six days without sleep but i am not a superhuman …i am like a zombi…

    im sure that your book will help me to be better and who knows maybe i ll sell your book in BS AS…..

    27th of december with lucky….hahaha Waiting is very hard

    i used the Silva Method , Sudarshan Kriya , MACA and gingko biloba….and the 4hourhourweek recommendations

    Thank you very much, you gave sense to my life since i red your book every day it is to fulfill a dream, sometimes one hits against the prejudices of the persons that you love … but thanks to you ,i realized that it is my life and that I want to be happy

  3. Tim. Ordered the new book today. Looking forward to learning and reading all the wonderful insights into life that you have for the new book.

    I have no idea if the book is supposed to be signed, I can’t find anything on Amazon that says it will be. But if it is, boy that will make it an even better birthday present for myself.

    Thanks. Jeffrey

  4. All sold out of the signed copies already? Seems as though it might be a good move to sign some more (Maybe for those of us that really want one, but missed it?) Aren’t the pre-sales important?

  5. Congrats on the signed copies being sold out (according to B&N). I really really wanted 5 copies, but had fun with my computer.

    Great work, the book looks better than I could have imagined.

  6. And I was just waiting for a new book to buy with Robb Wolf’s The Paleo Solution…

    When u live in Rio de Janeiro u have to group your amazon books!

    Ordered, retwitted, facebook-liked and stumble-liked.

  7. Hey Tim,

    Are the tele conversations with people who bought 5 copies available for the public or is it just private.?

    If public, When and where can we access those? Have you considered the level of privacy of the conversations?

    I see most people are ok with paleo style/slo carb (me too) and some are only vegetarian. You mentioned you’ve got both camps covered. I wonder if you have written something for people who can buy meat only less often or occasionally.

    The book however i believe will be way better than steroids. Well comparing with steroid itself is an insult and i am sorry.


  8. Tim – I can see this is now going viral, but not without a reason ofcourse. Could you share just one, small data with us? I mean: how big is you e-mail list?

  9. Hi Tim! This book sounds incredible as I love learning about the human body and what it is capable of doing, so thanks for all your time and research, I look forward to reading it!

    My question is this: I am anxious to get going with some of your techniques I have read about in your other blog, mainly that of eliminating white carbs etc, but I am currently breast-feeding my 3 month old baby boy (who is super cute by the way!) Can you tell me your opinion on using such methods while breast feeding? Is there some variation I could use if it is too strict for me right now? People have all told me to wait until I stop feeding, but I really feel adamant in my mind that I want to start now, even if it is just slowly. I have been overweight most of my life, so I have plenty of excess weight to shed, not just a few “baby kilos” if you know what I mean?! Please help! Thanks in advance! xxx

  10. Hey Tim or assistant,

    How about throwing an update on the post stating that the signed copies are gone. I was heartbroken when I discovered that I missed out (I simply don’t surf often enough-I’m on the RSS now).

    Oh well, I’m still broke enough that it’s nice to only have to buy one copy, but I’ll still pre-order for you. I recommend your first book constantly, but I haven’t been able to sell one copy, so I’m definitely not one of your 1,000 True Fans. You are one of my heroes though, and I thank you.


  11. Hi Tim,

    I can see the signed edition at the link below but there is no option to order it that I can see. If you click on Hardcover under Other Formats you get a form for ordering. Any ideas? Are they simply sold out already?

    Even if I cannot get a signed edition I will still pre-order, $14.58 is a great price., but signed would be better!

    All the best,

  12. Hola Tim,

    Congratulations on the new book – I’m sure it’s going to be a huge success. I absolutely loved 4HWW and I’ve pre-ordered 5 signed copies of your sophomore work. I’m looking forward to some major transformations over the coming year!

    Thank you for being so willing to share your knowledge and experiences – it’s good to know people can make a difference and have fun too!

  13. Hey Tim I ordered 5 signed books on 9/30/10…haven’t received an email about the call in october…..

    I could send you the screenshot again…

  14. Hey Tim,

    This book looks awesome I’m gonna pre-order my copy for Christmas lol. But I was wondering if you could give a hint about this whole 3 fold in testosterone level thing because I’ve used practically every T-booster supplement making those claims but they ended up being bogus. And btw that Geek to Freak thing was amazing!


  15. @Michal

    I would make a confident bet that the spreading of the word has little, if anything, to do with his email list. Heck, I can’t remember getting one email from him in all these years.

    The dude pushes out some bold and well exectuted/written content. So well that I have no embarrassment turning people on to him (15 min orgasm volunteers included). I advertise for the guy for free.

    Like most I follow his twitter and facebook to keep up with what playdate with life he has next.

    Now, if I could just get my tendinitis problem with my fingers (read: painful trigger finger in 7 digits) solved without surgery I would elevate his status to…well, to something.

  16. Looks good. I’ll order it.

    But this book reinforces the quality of the first one. Some topics that are covered show us that Tim already crossed the boundary of the acceptable amount of free time…

    Cheers and congratulations!

  17. Hey Tim-

    I will have my wife order this tonight as she is the “Keeper of the Amazon Account” in our household. I just logged onto the post today after buying a hard copy of The 4-Hour Workweek. I have had the audio book but wanted the book for the websites and to review certain material.

    I will read the new book and will see if my wife has an interest in it. (Now about that female orgasm thing…:)) Seriously, I am sure it has some great ideals.

    The cool thing (for me) about what you write is that you do not lecture, you educate. I like how you do not tell me “Jeno, you must live abroad for a six months.” You say, “It was awesome for me and here is a way if you want to try it.” I suspect the new book is the same way.

    Looking forward to checking it out and to reviewing T4HW in print.

    Best rgs,


  18. @Jscott – I am well aware of how this works, and Tim’s following on Twitter and Facebook is indeed impressive. I was just corious about himself spreading the word to first X people and was wandering how big is this initial group of people.

  19. Agree with Ben, you and Martin Berkhan I trust most. Just pre-ordered your book and December can’t come soon enough! I recommended 4HWW to everyone I know bc it changed my life and i look forward to devouring all the results of your health experimentation — Can.Not.Wait! i hope you never stop obsessing, look at the lives you change.

  20. Just pre-ordered your book. Can’t wait to read about your guinea pig experiences! Let us all know what signing 3000 books feels like haha.

  21. Just ordered a copy. Tim you rock dude. Jake from Denmark just letting you know how much I have benefited from reading your first book. I gave a presentation of it the other day in english class – great fun!

    Can’t wait to read the the 4 hour body and implement some cool stuff into my Crossfit.

    Best regards

  22. Tim, I’m so excited for your new book! Read The 4-Hour Workweek twice already. Spectacular content. Keep up the amazing work! 🙂

  23. Great news here Tim, I’m excited about the book and I know it will be quality written like the 4 hour work week. Should be some good info. that we could take from this and action immediately. Sounds like a real, no nonsense type of guide.

  24. Ah, TIm, I was getting excited there for a while. I had thought you were going to hit a thousand responses to this post. Alas, the comments seem to have dwindled significantly. Anyway, I pre ordered this as soon as my friend told me about it being available (about 2 hours after the post)! I’m really looking forward to reading it. 🙂

  25. Hi Tim am trying to order the signed copy but Barnes & Noble website does let me do it (i.e. there is no button). Are the signed copies sold out?

  26. For some reason my comments never get moderated the first time around :

    Hey Tim,

    Are the tele conversations with people who bought 5 copies available for the public or is it just private.?

    If public, When and where can we access those? Have you considered the level of privacy of the conversations?

    I see most people are ok with paleo style/slo carb (me too) and some are only vegetarian. You mentioned you’ve got both camps covered. I wonder if you have written something for people who can buy meat only less often or occasionally.

    The book however i believe will be way better than steroids. Well comparing with steroid itself is an insult and i am sorry.


  27. Pre-Order done.

    I think this website and all of Tim’s efforts are inspiring.

    I’m just a pop in and pop out fan of the site, but the knowledge that Tim shares is so valuable that I always walk away either having learned something new (how to get an egg out of the shell easily or hold your breath for 5 minutes) or found something new that I want to purchase(Total Immersion DVDs or Vibram 5 Fingers footwear).

    Long live Tim and this blog!

  28. Hola Tim.

    Me gustó mucho tu libro anterior. Vas a traducir este también al español?


    Hi Tim.

    I liked your previous book. Are you going to translate this one to spanish?



    1. Espero que si! It depends on which Spanish language publisher buys the rights, as Random House doesn’t translate the books they publish.

  29. Hi, I just saw your lecture on TED and was amazed, specially the last part where you said you want to apply what your learned to the education system.

    I discovered your book in A.J Jacobs’s book “My life as an experiment” and it’s quite fascinating because I have been experimenting with languages, skills and pedagogy for as long as a remember.

    My aim as an educator is now to apply what I have learned and help children.

    Hope to talk to you and like minded people about this exciting adventure!

    Looking forward to your new book

  30. Comment #700 and something!!!

    Looks like it’s going to be another success in one of the toughest areas to make it – publishing. Congrats! Can’t wait to read about the “behind the scenes.”

  31. Hey Tim,

    I know a lot about fitness. I’m a competative olympic weightlifter. But, I pre-ordered basically because; I like you, you seem genuine, and I really do benefit from your blogs. You are also issueing a fair price. That helps more than you think.


  32. Tim,

    PLEASE add more signed copies for those of us unfortunate enough not to have seen this until it was too late.

    Loved the first book, can’t wait for the second….third….fourth…….


  33. Ordered. Since I already work out and diet, any advice for what to do until then. Is there an optimum physical state to be in before following the advice in the book?

  34. Tim-

    Under the “2) Big media opportunities for you” of your post, you mention sending in before/after pics with details of grand feats of weight loss, muscle gain etc. with help from your blogs. I would like the opportunity to participate in making your book a success as well as take advantage of this great media oopportunity. My QUESTION is when would you like these to be sent in by so that you may make the best use of them?

    Thanks again Tim!


  35. Pre-ordered and itchin’ to read.

    I’ve been a 4HWW fan for years and have given away at least a dozen copies.

    I already owned a business and was hooked when you espoused ideas I already used.

    (batching and media fasting)

    Because of your health info, at 49 yo I’m back at my 30 yo weight and hit my proper BMI for the first time in 20 years.

    I’m in the best shape of my life. Can’t wait to get my paws on this new book!

    Hook a brotha up with a pre-pub copy? 😉

    Keep it up Tim!

  36. Is there anything in your book/research which looks into changing inherited germline mutations (as opposed to somatic mutations), in particular with cancers?

  37. Pre-ordered, Tim. First business, now the body. Can’t wait to read. Thank you for your encouragement a couple of years ago. Things are taking off. I’m interested in the Reversing ‘Permanent’ Injuries chapter. So, 4 Hour Workweek > 4 Hour Body…….. > 4 Hour Mind??

  38. Hey Tim,

    How was it meeting with Charles Poliquin?

    You have both influenced my life in such a positive way. Can’t wait for the book.


  39. I have read your first book a few times and have gotten something form it every time. Will be buying this book!

    Thanks for putting all this material together!

  40. Great to hear that you have a new book out. If I can take half of what I got from your first book I will be happy.

  41. Hey all!


    Thank you so very much for the comments. It’s humbling. I’m very grateful for all of the excitement!

    To answer a few people: yes, the signed copies sold out. If I can, I’ll try and do some more, but it does take time, alas.

    More soon and all the best,


  42. Does any of this new-age “body mechanics” stuff actually work?

    I am sure the book has many great things about how to become a healthier and happier person. But I would really like to see results from people who have tried this.

    Tim, are you going to start posting videos of people who tried tips from your book and succeeded? I would really love to see someone who is terribly out od shape try the steps in your book and really change themselves for the better. The visuals would do wonders for those who remain doubtful.

    Also, I owuld love to see and hear testimonials from people who tried tips in the book and utterly failed. I think that the people who failed would provide even more knowledge than those who succeeded. I like to hear stories of those who crashed and burned. I always learn something from those sort of testimonials.

    Please, post some videos!

  43. Hey Tim,

    I’m yet another person who ordered the 4 copies of 4HWW Expanded Edition back in December for the advance copy of this book. I haven’t heard anything yet from your assistant Amy and I did send her an e-mail yesterday mentioning that I hadn’t gotten any information. I just want to make sure I’m doing everything right because, like the other 800 people here, I’m really excited about getting this new book. I sent my e-mail to amy at fourhourworkweek dot com (yes, I did write it correctly in the send field). Let me know if there’s something I’m missing here.


    – Pat

  44. Tim,

    I just want to thank you for your post on the weight loss diet. Previous to the diet I had fatty liver disease, was 50lbs. overweight, and had very low testosterone levels. Life pretty much sucked at that point. I read the post and followed the diet to a “T” against everyone’s advice (even my wife’s). Now, 6 months later, I have normal testosterone levels and I lost 40+ lbs. I have also been following your weightlifting routine from your post and I feel strong and healthy. I am so grateful for your posts and look forward to my copy of the book shipping in December. I can’t thank you enough.

    I plan on sending some before and after pics this week. I hope they will help with your book. I think that everyone could benefit from your knowledge.

    Now if I can just figure out the muse thing….

    1. Congratulations, Chris! That’s outstanding. I imagine your wife is OK with the diet now? 🙂

      All the best,


  45. I just ordered a copy of the new book, and a copy of the new version of 4HWW. Can wait to read 4HB for the first time and 4HWW again.

    I tried you’re “Lose 20 lbs of fat in 30 days with out doing any exercise” diet last year as a way of cutting weight for a jiu jitsu tournament and it worked very well. Unfortunately I got injured and couldn’t compete in the tournament, (but that’s another story). Can’t wait to read the new book and and try out some of your experiments.


  46. I hope there’s some info on AC 11 and DNA repair. I’m getting ready to try that for Type I diabetes, but it’s on the horizon for all sorts of autoimmune disease. Started supplements to heal my adrenal stress and cortisone deficiency a few weeks ago and my insulin requirements have been cut in half. I’ve yet to “meet” anyone online whose tried it. Traditional doctors poo-poo the whole idea.

  47. Nice work Tim, looking forward to get a copy of the book once it is out in Germany. Is there a section in it of how to transform a Buddha-looking belly into a six-pack ?

    If not that is OK as I am looking forward to the orgasm section anyways 🙂


  48. Ha! the one thing you have kept quiet about – your sex life – we may now get to read about! Did you do the, ahem, research? 🙂

  49. Hi Tim –

    Before I bought my hardcover copy of “The Four Hour Work Week,” I discovered the audio-book version of it in my local library. I thought it was so terrific that I ordered the book online before I finished listening to the recording.

    First, I want to thank you for sharing your blueprint for living with the universe. This is a groundbreaking reference for the modern day. Second, since listening and reading your book, I have been amazed by the useful content on your site. As a result, I have heard you speak on a number of your video and audio links, so I would like to offer a suggestion. Read your new book yourself.

    The professional actor hired to read T4HWW is very good, but so much of your enthusiasm, nuance and contagious attitude does not translate in the reading by the actor. Rather than enthusiasm and friendliness, the actor occasionally sounds smug and superior. In your video and audio clips, you come off as accessible as a best friend – and that is a gift that can’t be trained. So if you have time NOT to outsource the reading of the new book, my advice is to do it yourself.

    I use a fair number of voice over people in my work, so I tend to listen to voice talent more critically than most. It is a real art when it comes to casting the right voice. And yours is perfect for your book because you write a lot like you speak.

    I have spread the word about you, your site and your book to more people than I can count. Thanks again for opening my eyes to your fresh ideas. I can’t wait for all of my friends to wake up to them, too.

    PS A lot of people I know left “Social Network” in a blue, depressed funk. I recommended they pick up your book to find something hopeful in the often impersonal digital domain. It’s a real antidote to a world dominated by the directive, “press one to continue this call in English…”

  50. Recommend 4-Hour Workweek to all my clients . . . looking forward to do the same thing for your new book!

    How do I go about getting an advance copy to review on my blog (I did this for Seth Godin’s Linchpin – read it in 24 hours).

    In any event – very excited about your new book! – Rich

  51. I really can’t wait for this book to come out. I am most of the time an audiobook kind of guy, but I just might read this one if the audiobook doesn’t come out soon. I’m sure you’ll let us know when the audiobook is ready too.

    Tim you are definitively the best. I will promote this book as much as I can!

  52. Whew! Had to go back and check my e-mail to make sure I was getting the signed copy… Can’t wait!

    Over the past couple years, I’ve lost about 80 lbs. through old fashioned hard work: a complete overhaul of my diet and a cross-training regimen (if you can call it that) of dancing, trail running, weight training, swimming, pilates and yoga. I want to take up outrigger canoe racing next!

    A little late coming to Four Hour Work Week, but loving it so far. I plan on reading it again once I finish. Recommending it to everyone I know! Keep up the good work.

  53. To anyone who bought multiple copies of Tim’s signed book, would it be alright if I could please buy just one signed copy from any of you? I’m from Manila and it took me a while to ask my best friend if I could have Barnes & Noble ship it to him in the US. By the time he got back to me, it was too late–the product page didn’t have the pre-order button anymore. The 4HWW changed my life and I would just like to keep a signed personal copy for myself.

    To Tim, thank you for your work. It really helps a lot. First three rounds of San Miguel beer on me when you find yourself in Manila.

    1. Hi Gian,

      If I don’t offer the signed copies again, please put up another comment a little closer to pub date. Thank you for your support!

      All the best,


  54. Hi Gian,

    I have 5 books coming (I was keen to ask Tim a couple of questions in the Q&A) so you are welcome to one when they arrive. Click my name to find my company website and send your email address through the contact form – I’ll be in touch.


  55. Hi Tim,

    Just (pre) ordered 5 signed copies. I am a great fan and many of my friends are too!

    Can’t wait till it arrives!

    Your ideas are VERY positive and inspiring. I have been searching for this for a very long time.

    Keep up the good work!

    Best regards,


  56. Hello Tim, Michael,

    Thanks for your reply. I feel better already 🙂

    Michael, thank you for your offer. It’s generous of you. I will try to get a signed book if Tim offers it again so you will not need to give up one copy for me. All the same, I will send you my email address.

    Tim, I will comment near the publication date to let you know about my progress. This is exciting!



  57. Hey Tim, I pre-ordered my copy of “The 4-Hour Body” from Amazon the day you announced. “The Four-Hour Work Week” was a life-changing book for me, primarily in changing the way that I look at the world and how I approach life. I’ve been a fan and supporter ever since.

    I only wish I didn’t have to wait until December to get the new book, but I know it’ll be worth the wait.

  58. I am insanely excited for this book, I read four-hour work week and i’m currently searching up muses and such. I like the writing style and how you say stuff other writers are afraid to say, such as the economics, outsourcing, and other, and best of all you tested it.

    Anyways I am even more interested in this book. I’ve been trying to find answers for tons of the common questions, but i do have one small question.

    Is the “sleep 2 hours and feel like you slept 8” polysapphic sleeping? cause this one is huge. I currently sleep around 6-7 hrs a day and really want to sleep less, but polysaphic sleeping is waaay to unconventional and hard for me to implement. If it is another technique i am very excited to read up on it.

    Etheir ways I can’t wait for the book and wish you good luck.

    1. BCAAs are impressive. Thanks for the link. I’ve been testing them mostly for recovery, where they work wonders. 15g about 30 min PRIOR to workouts seems to be the best timing thus far.

  59. Super excited about the “Becoming Superhuman” aspect of your course… can’t wait to be able to scale building or grow claws out of my hands.

    Well, the “incredible sex” thing seems like a good selling point too.

  60. Hey Tim. Ordered the x5 4HB copies prior to cut off date and no email from Amy. I’m in Aus don’t know if that will effect things. Just don’t wanna miss out…


  61. Ordered 6. From the quality of work I’ve seen so far, I recommend you as an intelligent source for unorthodox wisdom without reservation. Keep on keeping on.


  62. Very cool!

    I’m sure you’ll kick ass!

    I’m looking forward to this. Will there be kettlebells involved? I think my pal Zach Even esh sent you a TGU video we shot in my back yard.



  63. This is what I have been looking for.

    I have spent a lot of money with doctor’s trying to figure out three major conditions I came to the conclusion; doctor are in for the money they won’t help as much as doing your own research and experimentation.

    Since, I have fix myself of IBS, allergies, hair loss, depression and hemorrhoids. I HAVE ORDERED MY BOOK and can’t wait.

    Will be counting the days

    Best of Luck and thank you for putting together these great books

  64. Hi Tim!

    Do you intend to sell a (brazillian) portuguese version of that book, The 4-hour body? I’d already bought your portuguese version of the 4-hour Workweek and It was awsome!

    Hugs from Brazil 😉

  65. Pre-ordered. The first book was awesome, and you seem more excited about this one. 4 hour workweek spawned an army of the “new rich” (myself included), with a dream that doesn’t include sheer accumulation – and this sounds like it will deliver on another dream (of weightloss, weight gain, energy, and other important human body information) where the capitalist medical industry and most other nothing but hype products and advice have failed us as consumers.

  66. Description sounds incredible, and after being super happy about your 4HWW book, I just pre-ordered this one. So good luck with it may it have an amazing start!

  67. Just orderd a copy of the book and the cd of the audi version.

    International shipping to Spain.

    ETA January 16th 2011

    Being a BJJ practioner ,really interested in your perspective.

    Be well

  68. Hi Tim,

    I’m sure you are getting tons of email on this, but like Pat above, I have sent Amy a message about the promo last year and have not heard anything about the details of receiving the new book – which I can’t wait to get my hands on btw.

    Can you help?

    1. On it. Just emailed Amy. Sorry for the confusion. She can get 500+ email a day, so sometimes things get missed, sadly. But… on it!

  69. The 4HWW was like crack for office jockeys like me. The 4HB appears to be the Swiss army knife of guides to better being. My order is placed. Thanks for the energizing read. The profitable muse continues to elude me but my perspective on employing different methods and tech have certainly improved thanks to you and Kevin. Cheers!

  70. Tim,

    Congrats on the book! I already pre-ordered my copy and I should say it’s gonna be huge here in Brazil.

    Now, with the new book coming out are you going to keep the name of this blog? You should think of smthing more in the lines of “The 4-hour Philosophy” with Tim Ferriss!!!



  71. Hey Tim,

    Quick question: I see this book covers a lot of physical performance based information. Do you talk about mental/brain/neurological performance? Enhancing memory, working out the brain, etc.

    Also, I’m working on a bit of a hectic schedule right now. Your “sleep 2 hours and feel fully rested” bit intrigues me but I’d like to start doing that a bit sooner than December. Would you mind pointing me in the right direction so I can learn more about this? I’d appreciate it.

    Let me know if you stop by Orlando some time. I owe you a round of drinks! My business is taking off and your book played a huge part in it.

    Thanks mate,


  72. Tim,

    I pre-ordered from Amazon, please let me know if you offer the signed copies again. You continue to be a inspiration for all of us. Keep up the good work brother.



    P.S. Anymore TV specials like the Yabusame one?
