Review of The 4-Hour Body and Starting Strength

The 4-Hour Body by Tim Ferris

The 4-Hour Body is a book covering many topics around diet and exercise. Tim himself doesn’t recommend reading it from cover to cover, so I read about 2 thirds that were interesting to me.

The diet part is the longest. His recommendation to start the day with a high-protein meal is sound, I often do that myself (5 or 6 eggs). However, his obsession with insulin levels seems unnecessary (see Guyenet and Masterjohn). There’s plenty of people who lost a lot of weight on the diet, but I haven’t tried it, since I have the exact opposite problem.

I’ve tried the Occam’s protocol, which is a training program for maximal muscle gain. I ran it for 2 months and gained about 6 kilos of weight, some of which was fat but most was muscle. My rate of weight gain was lower than what Tim promised, which was most likely caused by the following two factors.
  • I ran a few orienteering races while doing the program, but Tim doesn’t recommend any cardio. This was intentional on my side.
  • I started eating as much protein as Tim suggested, but felt horrible. 7 days into the program, a blood test revealed that my kidneys couldn’t keep up with the protein intake. I immediately started eating less and then slowly increased protein intake, but I’ve started feeling strange “in the kidneys” again. This must have been the first time I was aware of my kidneys.
Part of the weight gain might have been regression to the mean, since people’s weight is typically the lowest at the end of the summer which is when I started the program. Regression to the mean could only explain half of the weight gain, though.

I’m convinced the program works, probably much better if you’re able to tolerate more protein. However, my biggest gripe is how Tim sells it. Tim likes to mention the 80/20 rule: you can get 80% of the results by only doing the important 20% of the effort. The title of the book comes from the 4 hours Tim spent in the gym during the month he gained an enormous amount of muscle mass.

The hard part of Occam’s protocol is eating enough protein and calories, which Tim mentions himself many times. I had to think constantly about food and when I managed to hit the protein target, I felt full, lethargic and overall terrible. It felt like 80% of effort for 80% of results.

When the 2 months ended, I switched to Starting Strength which in my opinion achieves what The 4-Hour Body tries to be. For example, Tim has a separate section on how to fix tight muscles by time-consuming exercises or expensive methods for which he flew to another city, but I managed to fix my tight hamstrings just by doing the exercises in Starting Strength. I got much more bang for the buck by following Starting Strength, but more on that in a separate review.

Over the years, I’ve listened to a couple of Tim’s podcasts and some of his interviews, but I have never become a big fan. After reading his book I think I know why. He's a great salesman, but the things he's selling aren't that good.

Starting Strength by Mark Rippetoe

Starting Strength is a beginner barbell program with only 5 exercises (squat, deadlift, over-head press, bench press and power clean). All exercises are explained in great detail—just the squat chapter has about 60 pages.

I didn’t run the Starting Strength linear progression exactly, but rather went with Phrak’s Greyskull LP Variant recommended on Reddit. The two programs are close enough: 4 out of the 5 exercises are the same and you also do 3 sets of 5 repetitions. Weight increases and deloading are the same too.

Starting Strength focuses on strength gain. However, the best part about doing the program were bonus improvements that I didn’t expect.
  • Improved hamstrings flexibility: I suffered from tight hamstrings whenever I played hockey or rode a bike. I’ve tried massages, foam rolling, hot baths and stretching, always achieving only a short-term effect. Just before starting the program I couldn’t touch my toes and now I can press all my fingers against the ground (no palms yet). And no, stretching is not part of the program, so such a huge progress was very surprising to me.
  • Much less muscle soreness: I used to have too much muscle soreness from my semi-regular sport training, but now that is not an issue anymore. I also don’t remember this being promised anywhere, so that’s another surprise.
  • Muscle/weight gain: Even though it’s primary a strength program, I’ve gained about 1 kilogram per month on the program.
  • More strength everywhere: I used to subconsciously search for things to lean against while standing. These days, standing is just easy. Also, free-ride skiing used to be very hard on my legs, but now it feels at least 3 times easier. This is not that surprising, as the exercises hit almost all the muscles.
In the end Starting Strength fulfills the goals of The 4-Hour Body much better, at least for me. Only 5 exercises packaged in a simple-to-follow program feel like the 20% of effort that bring me 80% of results. Yes, my hamstrings could get more flexible by doing more specific work, but as it is now it’s all good.

Note that Mark Rippetoe can be dogmatic, e.g. he repeatedly says in the book that the squat works your hamstrings a lot, but there’s now good scientific evidence that that’s not true. Starting Strength is a great start but it’s definitely not the end.

Conclusion

I’m now well in my 30s and I think now is the right time to get serious about health. Thanks to a lot of trial and error in the last 5 years, I’ve conquered regular insomnia and migraines. Barbell training is another great addition, especially the squat and deadlift feel like cheat codes to life.

The conventional thinking is that your health deteriorates with age but I’d like to keep improving as long as possible. What if there are more cheat codes to be discovered?

Book Review: The Old Man, the Sea and the PhD by Martin Lukačišin

The best thing about The Old Man, the Sea and the PhD is that it’s very short. I read it while travelling to the airport and waiting at the security check. It reads very well and it’s packed with ideas. Each idea is presented using a parable which makes them very easy to remember.

The last chapter likens the life of a PhD student to Hemingway’s The Old Man and The Sea, which is where the name of the book comes from. I found this analogy the best and most memorable.

During my time in academia, I wanted to write similar thoughts in a blog post (or two) but I always deleted what I wrote, since I didn’t believe that academia could be fixed and thus my drafts were pure rants. The author is slightly more optimistic and tries to provide solutions, though he still admits that the book is very negative about academia.

I think academia will never get fixed, since it’s stuck in a bad equilibrium, just like schools, medicine, politics or airport security checks. We think academia is about science, schools are about education, medicine is about health, politics about improving lives of ordinary people and airport checks are about security. However, all of them are primarily about something else and the stated purpose is at best a secondary side-effect.

The real issue with academia—in my opinion—is that it’s primary about academics gaining prestige and status among other academics. Science ends up being a secondary side-effect of this process. The author hints at it in the very last paragraph of the book but unfortunately doesn’t expand on the idea. For this reason, I recommend complementing The Old Man, the Sea and the PhD with Elephant in The Brain by Kevin Simler and Robin Hanson. You’ll have a better understanding why the life of a PhD student is as miserable as Martin Lukačišin describes it.

Note: this review has also been published on Amazon.

Book review: The Simple Path to Wealth by JL Collins

I’ve always recommended JL Collins’ Stock Series to anyone interested in saving, investing and early retirement. JL now took the series and other posts from his blog, polished them and made into a book.

The good

Everything is explained very simply and JL uses a lot of stories. It’s also very short, so you won’t be bored reading it.

You’ll learn the basics about stocks and bonds, how the market works and that a very good investment strategy is actually very simple, with only two index funds. But more importantly, it will give you a lot of crucial advice for this endeavor.
  • There will be times when your portfolio drops 20% within a month and you’ll feel like you’ve made a huge mistake. The solution is simple: treat it as “Sale! Everything 20% off”. The book has a lot of other tricks to make you a calm investor.
  • Chapter III "It has never been about retirement" is the single best short piece I’ve read about the philosophy of saving and early retirement. If you need motivation for saving and investing, this book will give you plenty.
  • I also really like the final chapter on risk. No, you can’t be sure the 4% rule will work forever. You can’t be sure that Earth won’t be hit by an asteroid. We live in uncertainty, but having savings can only help you.

The bad

My biggest complaint is the incorrect advice about international investing. To be fair, most investing books are also somewhat incorrect, but JL goes too far and recommends only owning American companies. This is on three grounds: high risk, big American companies are global and it’s more expensive. I don't buy any of these 3 arguments.
  • It's true that international investing sometimes bears more risk, but this risk has also been rewarded, for example emerging markets over-performed the rest of the world by 2% yearly in the last 40 years.
  • The difference in price these days is about 0.1% in yearly fees between an American and a global fund. That’s a very small price for a much higher diversification.
  • JL says the world is getting more globalized and connected, so having only American companies is enough – you get exposed to all economies anyway (according to him). Increased globalization is happening, but the stock markets ignore that. Comparing last 15 years, emerging markets gained 6.4% yearly while developed world gained 3.3% (MSCI World IMI vs. MSCI EM IMI).
Some small complaints:
  • I wish the book used real (=inflation-adjusted) returns. If the index grew 12% yearly when 4% of that was inflation, saying that your wealth grew 12% is very misleading.
  • JL uses a Bell curve to illustrate the variability of stock returns, but to me Bell curve means lack of variability. In reality, stock returns have a long-tailed distribution and that’s one of the reasons why it’s so easy to under-perform the index.
  • I’m curious why JL didn’t mention Betterment (and robo-advisors in general), because he writes about it positively on his blog. In the book, he says multiple times his strategy is about simplicity. However, avoiding Betterment adds 3 times more complexity for an average person.

Final verdict

Go read the book, it’s awesome. Yes, there are factual inaccuracies, but you can correct that by reading All About Asset Allocation or A Random Walk Down Wall Street instead. This book excels in things that other books get wrong or ignore—the psychological and philosophical aspects of investing.

Disclaimer: I got an early copy of the book in exchange for review here and on Amazon. I won’t receive any compensation if it sells well, so I didn’t have an incentive for a good review.

6 non-fiction books that changed my life

Throughout my life I have read plenty of non-fiction books that changed the way I think about everything. Most of them are based on scientific research, although many ideas are just theories in need for more testing. Your parents, teachers, friends and even politicians taught you many false beliefs. By changing them to something more scientific, you will experience much less cognitive dissonance, which is the mental stress you experience when reality doesn't match your beliefs. Your mind will be more at peace.

The effects of my reading so far have been far-reaching:
  • Reading a blog about financial freedom helped me cope with my health diagnosis.
  • Being honest and vulnerable is great not only for your personal life, but your professional life as well. For example, your colleagues will respect you more if you don't hesitate to admit a mistake.
  • Reading economic theories made me adjust my moral values and philosophy; see for example this blog post.
I'm not saying that these books contain the ultimate answers, but by reading them I have become slightly less wrong about everything.
Every step of the way I was wrong. About everything. All throughout my life, I was flat-out wrong about myself, others, society, culture, the world, the universe, everything. And I hope that will continue to be the case for the rest of my life.
...
There's that famous Michael Jordan quote about failing over and over and over again, and that’s why he succeeds. Well, I am always wrong about everything, and that's why my life improves.


Mark Manson in Why I’m Wrong About Everything (And So Are You)
If you are a fan of political correctness, many of these books will disappoint you. Reality doesn't care about offending someone; reality just is. For each book I tried to list one idea that stuck with me the most from the book.

The Happiness Hypothesis: Finding Modern Truth in Ancient Wisdom, by Jonathan Haidt

This is my number one book that I have read about 5 times over the years. Whenever I'm facing a big decision like choosing a place to live or a job, I consult the book to see how it will affect my happiness. Happiness comes mostly from other people and if you want to be happier by means of money, buy experiences, spend it on others or don't spend it.

The book looks at different philosophies through the lens of science and how they affect happiness. It turns out that a large part of the Greek or Buddhist philosophies survived scientific tests. The book also tells a lot of fascinating results in psychology, not necessarily related to happiness.

One idea: Suppose there are two people, one has just won one million dollars in lottery and the other has just become quadriplegic, so he can't move from his neck down. Who will be happier one year from now? Surprisingly, they will be on about the same level. Our minds are very adaptive and they get used to new situations quickly.

Models: Attract Women Through Honesty, by Mark Manson

Even though this is a book about women, it had big effect on other aspects of my life as well. If you ignore the parts specifically about women, it reads as an excellent lifestyle guide. Better relationships and friendships are then by-products of improved lifestyle and behaviour and they seem almost effortless. The book also taught me how to be more assertive, expressive and confident.

A large part of the book is devoted to vulnerability and honesty which are two necessary qualities for stable relationships. Being vulnerable doesn't mean showing weakness, it signals inner strength and is therefore very manly (here is an excerpt of the book about vulnerability).

One idea: Polarization – don't be afraid to admit that you have listened to Britney Spears' song Toxic more times than appropriate 10 minutes into a conversation (alright, alright, that's me!). This will push away some people very quickly, but you will also find the ones you like quicker.

P.S. Mark Manson has an awesome blog (gender-neutral these days), where he writes about everything life-related often backed up by research in psychology. He's the guy I cited in the beginning of this post.

Financial Freedom through Badassity, by Mr Money Mustache

I'm cheating a bit here, since this is not a book but a blog. Before reading it, I used to save about 20% of my income but now it's up to 50% even with a lot of travelling. And if you save 50%, you can retire in 17 years. You will also become happier by spending less and saving more. Retiring early doesn't mean that you stop working, you can work for less or for free (volunteering).

If you are interested in how it can be done, go to the "start here" menu item or read my favourite post.

One idea: Nothing beats the stock market when it comes to long term returns. Stock market is volatile and sometimes you gain 0% in 10 years, but over 25-30 years the yields are better than for any other form of investment.

Is there anything good about men?: How Cultures Flourish by Exploiting Men, by Roy Baumeister

After reading this book I understand myself and other men much better. It explains why evolution made us behave the way we do. The book also debunks most of the myths that modern (third-wave) feminism is built on.

There are two main differences between the two genders: nature rolls the dice more with men and different genders have different motivations. For example, men and women have similar IQ on average, but men are overrepresented among people with high IQ as well as among people with low IQ. Men also have different motivations, like willingness to take big risks. Cultures have been exploiting this – big risks often led to great results but many men have died while taking risks, or became very poor and homeless.

One idea: I used to think that women are more social than men. If being social is good, why hasn't evolution made men as social as women? Evolution actually did make men social but in a different sense. Women prefer few intimate one-on-one relationships while men prefer plenty of shallow relationships.

P.S. You can read an invited address that Baumeister gave at a meeting of the American Psychological Association. The book expands on the topics in the talk.

Capitalism and Freedom, by Milton Friedman

I like to think about capitalism using a sharp knife metaphor. So far we haven't found a better tool for cutting food than knives. Their greatest strength, sharpness, can also lead to injuries. This book talks about why capitalism is a sharp tool and how to avoid injuries. It is very old and economics has made a lot of progress since then, but I still like it a lot for how it changed my world view and moral values.

Capitalism and high levels of freedom don't mean that there is no welfare. The Economist recently wrote: "When it comes to choice, Milton Friedman would be more at home in Stockholm than in Washington, DC." Historically, Sweden has been very free and capitalist. Milton Friedman was also a proponent of negative income tax, a very simple welfare program that is more efficient than what most countries have now.

One idea: Government should be organized on multiple levels. If possible, a government function should be done at the lowest level. It's easier for you to influence a local politician and if you don't like it, you can move 10 km to another town. Things that require a lot of coordination or are inefficient on a local level, like the military or taxing pollution, need to be done at the highest levels.

P.S. Milton Friedman has brilliant rhetoric skills. Even if you don't like freedom or capitalism, I suggest watching some of his videos on YouTube.

Predictably Irrational: The Hidden Forces That Shape Our Decisions, by Dan Ariely

This book saved me a lot of money. It explains many of the psychological tricks that marketers are trying to play on us. Stay cautious every time you see the word free or there are too many options given to you.

Experiences are affected by our expectations. A fancy meal eaten in McDonald's will appear tasteless while the same meal eaten in a fancy restaurant will appear excellent. Similar thing is true for many things ranging from music to pills, so you can improve your perception by increasing your expectations.

One idea: Sellers are trying to trick you by having expensive items that no one buys. Suppose a restaurant has meals costing between 10 to 20 euros. Now suppose they add a couple of meals that cost 30 euros. Nobody will ever order those, but people will spend more now than before.

Other great books

The following books were not that life-changing but they are still great. Perhaps they would be life-changing if I read them 5 years earlier.
