Book 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% with a few bags of ice
* 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.

From the Hardcover edition.

1.0 out of 5 stars 4 Hour Baloney, save your money February 22, 2011
Format:Hardcover|Verified Purchase
Most of the 5-star reviews for 4HB came up on the first day. Given that Tim Ferriss has previously endorsed outsourcing in his Four Hour Workweek, I wonder how many of those 5-star reviews were from his personal assistants abroad.

Let me start with my bona fides: I am a currently practicing and licensed physician in the state of California. I graduated from Stanford University School of Medicine. I am a black belt and a lifelong athlete, and I have been weight training for over 20 years-- and unlike Mr. Ferriss, without injuring myself in any way, ever. I have no financial interest in his book or any other product discussed here.

Regarding the depth of my review of The 4-Hour Body, I spent over [...] on the equipment, supplements, and ultrasound machine recommended in the book. I bought the BodyMetrix Professional ultrasound and software he recommends by Intelametrix ([...] after discount for mentioning 4HB book), and completed the 1-on-1 online training despite the fact I am previously certified in performing ultrasound. I engaged my friends and colleagues in a "Fat off" competition with obsessive and objective weight and body fat measurements and followed the routine for 5 weeks as perfectly as I was able. I also experimented (like Mr. Ferriss) using continuous glucose measurement (CGM) to assess minute-to-minute glucose responses to food and exercise using both the DexCom system he recommends as well as the MiniMed Guardian system. I plan to upload a photo of the nutritional supplements I bought, which nearly cover my kitchen table. I downloaded apps to my phone for recording each workout obsessively, and more importantly to help with the very slow rep time he recommends.

3.0 out of 5 stars Over 100 Five Star reviews in less than a day? December 14, 2010
By Momo
Format:Hardcover|Verified Purchase
Pro: It has a lot of great information for people who are new to dieting and exercise.
Easy to read. The split into different chapters you can read without having to read the whole book was a smart choice.
Simple programs.

Con: All the information isn't exactly new or just in this book. For example, the diet is Paleo, which is fine, but not what I expected from the ads. I really hoped for something new here, and what is new sounds dubious at best.
Some of the claims in the books description are a little exaggerated.
The work out is not the best. It's great if you are new to working out, but it's not enough for someone who is already athletic and looking to improve. If you want to be the best athlete you can, this will take you far but it will not get you there.
Reversing permanent injuries can be expensive.

I have a problem with his scientific method. He did a lot of these experiments only on himself, and one after another in a short period of time. His results might be skewed. I'm currently applying a few of his suggestions and have been for 2 weeks. I will update this review in the future if there is any radicle change, but as of now nothing has really happened.

I also do not like that this book has gotten so many perfect reviews so quickly, and that critical reviews are being removed.

All in all, the book is grand if you need to be introduced to the word of nutrition and exercise. But if you have read widely on the subjects already and looking for something different and radically new, this book doesn't really deliver.

4.0 out of 5 stars Here's what I got out of it December 14, 2010
I enjoyed the book. I'm not going to claim that the book is perfect or earth-shattering or anything like that. I did find it entertaining to read all the stuff Tim Ferriss put himself through. I've also benefited from some of his recommendations (though not all). Here's what's in the book so you can make your own decision. I've read all 571 pages and tried most of the strategies (I had my copy for a while because I got my hands on an advanced copy).

Ferriss spent more than a decade researching, monitoring, and noting the progress of his own mind and body. He served as his own laboratory genea pig and also played the role of a doctor, physical therapist, and coach to prepare for this book. Like a school boy, Ferris teaches you how to get your classwork done fast so you can go out and play. He asks you to be skeptical of the book and try only that which you think will help you.

Here's what's in it:

Chapter 1: Fundamentals--First And Foremost

* Ferriss describes the "Mininum Effective Dose" (doing the bare minimum to gain the most desired outcome).

Chapter 2: Ground Zero--Getting Started and Swaraj

* Uses Mahatma Gandhi reference to make the case that only we can govern our body and destiny by what we purposely choose to do.

Chapter 3: Subtracting Fat

Five rules for cutting body fat:
1. Avoid "white" carbohydrates
2. Eat the same few meals over and over again
3. Don't drink calories
4. Don't eat fruit

What's the best kindle weight loss book?
Ultrametabolism by Dr. Mark Hyman. It is a realistic, logical guide to feeding the human body properly.

Is this book applicable to women?
The marketing may be geared predominantly to a male demographic (I can't say one way or the other), but I'm sure the content of the book has plenty of info for women and men (and much that applies to both).

Book not available in India
Unfortunately, not all books are available for download to Kindles world wide. I cannot buy and download many books published by Amazon in the UK for example. It has to do with international publishing agreements. Rights need to be established for each country.

Amazon Should Be Emabarrassed!
What's worse, some low ratings have disappeared from the Amazon review pages. What's up with that?

It's extremely obvious that Ferris has his acolytes stacking the reviews, most after getting free copies and being urged to tout this quackery.

notice the new surge of positive reviews?
Clearly he is gaming the reviews. If you read the 4 hour workweek you know he discussed hiring employees in India to work full time at just $400 per month. Many of the people in these reviews are made up. The reviews are short...without much detail, but are giving him 5 stars.
