The Four Hour Body: An Uncommon Guide to Rapid Fat-Loss, Incredible Sex, and Becoming Superhuman

By: Tim Ferriss

Matt Sodoma’s Review Score: 8/10 (First half of the book recommended)

     Book Version        Kindle Version

New York Time’s Best Selling author Tim Ferriss has brought us another four hour book.  If you have not read The Four Hour Work Week then I highly recommend it.  It seems that through all of his business start ups and life experiences, Tim has been OCD about his fitness.  This has allowed him to provide all of his readers with a first-hand account of what works and what does not work.

Tim Ferris’s self-experimentation is amazing.  He is not afraid to inject or swallow substances that may or may not help his body.  He has done the experimentation on himself, so we do not have to do it as the reader.  Ferriss provides numerous examples of injections, steroids, vitamins, workout routines, etc.

Through Tim’s experimentation, he has developed what he refers to as the slow carb diet.  Basically, the diet consists of eating high protein, legumes for your carbohydrates, and lots of vegetables like spinach.  Most importantly, Ferriss expresses the importance of a lifestyle consisting of supplementation, diet, and working out.  The percentages are different for all of us, but basically, you need a good diet, you need supplementation to get the protein and carbs to your muscles, and you need to workout to help maximize the effects.  Find out more about diet, supplementation, and working out here.

The first half of The Four Hour Body: An Uncommon Guide to Rapid Fat Loss, Incredible Sex, and Becoming Superhuman is an excellent read.  It contains useful information for your diet, the science behind it, and what has worked and what doesn’t.  It is also a how-to guide and a step-by-step guide to fitness.  The slo-carb diet is simple to follow and may even seem too simple to most readers.  Find out more about fitness and applying some of the slow-carb techniques at

The second half of The Four Hour Body consists of short chapters that seem out of place or stuffed in for extra reading material.  Some of these chapters are useful tips, others are story-telling, and others are niche specific.  Like Tim mentions at the beginning, the book is not meant for front-to-back reading and he does not recommend it.  Ferriss tells you to pick the chapters that apply to what you want to know.  Fascinated by the information I found in the first half of The Four Hour Body, I read the book front-to-back, likely being the reason for my 8/10 rating.

In my opinion, this book is not as good as The Four Hour Work Week, but there is still quality information that you can learn and use from the 4 hour body.  I recommend the first half of the book, but you could skip over the second half.

    I think you are right to split the book in two, and I agree about the second part. Personally I did a lot of research – mostly google – after the book was published, and so many of his claims turned out to be – well, less than straight up – that I gave the book a much lower rating – more like 3 out of 10. The radical weight loss – which was done entirely with diuretics – is a pretty good example in my mind.

    Thank you for your comment Cinn Fields. True, a lot of his information is inflated or unrealistic. But that is also what helps his book sell. So, I suppose it is a trade off to have some exaggerations and fluffed up results for some quality experimentation. I mostly just enjoyed reading about his supplementation, muscle gain, and “diet” techniques and used the ones that I could to my own diet.
