Ask HN: Hacking your body?

11 points by richtaur ↗ HN
Most HN readers are probably hackers. Hacking on and improving soft/hardware is what drives us daily, and I've read that many of you have taken your hacking skills beyond tech. I enjoy hacking outside of my computer too (using tricks to improve cooking, wardrobe, daily life, etc.), but I've yet to find a good way to get into shape and stay that way.

Do any of you have hacks you've used on yourself or others to improve fitness/health?

In a nutshell, get Tim Ferriss's book: The 4-Hour Body [1]

I got it last December and have slowly, but steadily implementing some of the strategies he prescribes. You don't necessarily have to follow everything he suggests (and probably couldn't) but it's full of good advice.

I haven't actually read the book, and some of his tips may be useful, but I stopped reading when I saw this in the book synopsis:

"How Tim gained 34 pounds of muscle in 28 days"

I'm a biologist and I'm calling bullshit on this claim. It is physiologically impossible to gain that much lean muscle mass in a month under the best conditions. Your body can only synthesize about 2lbs of lean muscle per month. The rest of those 32 pounds is likely glycogen (water weight) and fat.

Well, here's how he did it [1] I would be interested in your opinion -- you aren't the first to be dubious of his claims.

This sounds like so much bullshit. Aside from it being physically impossible to add so much muscle in such a short time, here's a few things that jump right out as being obviously fake:

Suit size went from 40 short to 44 regular. The short and regular is the sleeve length. I'm not seeing how this changes regardless of how much muscle you put on.

The before photos look obviously bad, visible shadow. The after pictures look much better, better lighting.

No tan in the before pic but tan and hairless in the after. Bodybuilders do this to give the appearance of more muscle.

The distance from camera changes in the before pics. Gives the appearance of being smaller or it stretches him out so he looks skinnier.

which strategies of tim's have you implemented, and what have been the results?
Well, for me, it's always about being aware. So, I may not eat 100% slow-carbs all the time (it just isn't possible given my particular situation). But, when possible I avoid white foods (dairy, bread, pasta) and eat fiber rich foods (legumes especially). For example, I used to eat low-fat yogurt with granola and fruit every single morning. I've given that up with a low-sugar high-protein bar and it's really made a difference (400 calories / high sugar to 180 calories / low-sugar for breakfast). I also have hypoglycemia issues so it's better to avoid sugar anyways.

I wish I had more hard data to share, but I don't.

It's a prime example of good 21st century marketing, so at least that's something of use for a lot of HNers. The scientific and nutritional parts are a "bit mixed", to put it nicely. If I remember correctly, parts of it basically went "this is scientifically proven because Wikipedia says so".

His "slow-carb" diet is basically a easier to digest low-carb diet mixed with a bit of CKD. Kettlebells are good, but surely not the workout panacea he promises (and actually somewhat risky for people with back or knee problems who are doing this without proper supervision). You should be able to get most of that info on the net, and there you often have some much-needed perspective and discussions about it.

And those are the moderate parts of the book. If I can poke some holes into that, I don't even want to know what might be wrong with the more risque parts (injury prevention, bodybuilding, supplements). And the sex chapters would fit in nicely into drivel like "The Game"...

Don't get me wrong, I would love to have a "body hacks" book, but I'd prefer if it were done with a bit of scientific rigor, not just "this worked for me, control group: me".

Sorry, you come off as just another "hater" looking to pick apart a basically good book on hacking ones body. It's not just about weight loss or gaining strength. There are chapters on sex, sleep, free diving, etc. that would probably interest many people on HN.

I don't think one should read it as a scientific or nutrition text book, but it's not fair to dismiss it as pure marketing either. There's lots of works cited and professional observations through out the book. You can't write a 500+ page NYT and Amazon bestseller based off of information you pull from Wikipedia articles no matter how good the marketing is.

  >His "slow-carb" diet is basically a easier to digest low-carb diet mixed with a bit of CKD. 
To me, the slow-carb way of life differs from the low-carb way of life in that you don't avoid all carbs, but be smart about the ones you choose. That's an important distinction. For instance, choosing dense nutrient-rich vegetables like spinach and broccoli over corn and green beans. He really encourages legumes like lentils and beans in the book, which I haven't seen as much in other low-carb style books.

  >Kettlebells are good, but surely not the workout panacea he promises (and actually somewhat risky for people with back or knee problems who are doing this without proper supervision).
Yeah, if you have serious health issues, please consult a physician. Every diet/health/fitness book has this basic disclaimer in the front pages. If it hurts, you are probably doing something very wrong.

  >You should be able to get most of that info on the net, and there you often have some much-needed perspective and discussions about it. 
Scouring the net for this information from various sources of questionable authority is a very bad use of one's time/money. Purchasing a 500+ page book for less than $20 which contains all of the information you need to get started on your body-hacking journey is a very good use of one's time/money.

  >And those are the moderate parts of the book. If I can poke some holes into that, I don't even want to know what might be wrong with the more risque parts (injury prevention, bodybuilding, supplements). And the sex chapters would fit in nicely into drivel like "The Game"...
I'm not so interested in the "risque parts" and I wouldn't knock the sex parts until you've tried them ;) Really, you can avoid those parts if you want and still have loads of material to dive into and research farther.

  >Don't get me wrong, I would love to have a "body hacks" book, but I'd prefer if it were done with a bit of scientific rigor, not just "this worked for me, control group: me".
Honestly, I was skeptical at first too. But Tim really doesn't say "this worked for me, control group: me". There are dozens of on-the-field and in-the-lab experts he mentions (you can research their credentials/expertise further very easily, as I did) and hundreds of subjects. Again, it's not a scientific thesis -- it's a guide book on hacking one's body in a very efficient manner.
Especially when I'm hacking my own, non-renewable, non-refundable body I'd want more than a bit of scientific proof that a) it works and b) it won't mess me up. Whereas your regular self-help book might just wreck your bank account (at the worst), some of the things in this book might do a lot worse things. Yes, they might not, too. But are you willing to take those risks? (Again, the slow-carb diet and the kettlebell workouts are probably amongst the least controversial parts of the book)

And yes, I've read the book, most of the "hacks" have been done by Tim on himself, sometimes with a with/without methodology. Not really bad and actually something that everyone who modifies his lifestyle should do. But that still doesn't replace blinded studies, never mind that he very rarely states how many "hacks" he's been doing at the same time. And never mind that he's been quite athletic for most of his life, so a lot of the techniques won't work that well for your average pudgy nerd.

It's not a very expensive book, on the other hand. But if someone buys it, I'd recommend taking everything cum grano salis and do your internet research before embarking on a "hack", especially if it means taking supplements (e.g. the bro-sciency ECA stack).

Warning, NSFW: chaosandpain.blogspot.com. An aggressive, foul-mouthed intellectual's take on power-lifting and nutrition.
For those at work, his advice boils down to this...

DO'S:

-Low repition, heavy weight, full-body lifts

-Boost your testosterone levels through things like a high protein diet

-Read more and be intellectually curious

DO NOT'S:

-Avoid soy or other foods/activities that lower your testosterone levels

-Avoid endurance exercises (modern marathoning, etc.) that wear-out your joints and cause cardiac disease

-Avoid blindly accepting the conventional wisdom on health and fitness

I didn't check the site yet since i'm at work, but endurance exercises cause cardiac disease?

Aren't endurance exercises meant to strengthen the cardiac muscle and thus having a positive effect on your cardiac health?

(btw your list reads to me as "do not avoid soy", which I think is the opposite)
"DO NOT'S" should be read as a pluralized list heading, not as a prefix to each list item.
PARK RULES

Do not:

* Run

* Shout

* Play ball games

>"a good way to get into shape and stay that way."

I started refereeing soccer this past year. The emphasis placed upon on field performance was sufficient substitute for competition and because of the many levels at which the game is played, there have been ample opportunities at an appropriate level as my fitness has improved. Most importantly, as I have received progressively more competitive assignments it has allowed me to reframe exercise (which connotates a certain amount of drudgery in my mind) to training. The fact that refereeing pays for the shoes it requires and doesn't require space in the house beyond that required for a gymbag, is a plus as well.

Here's my take:

Remove any mindset that exercise is something you do 30 minutes three times a week....that's bulldust. You live in your body 24/7. Any moment is a moment to exercise. Sitting at the pc? pay attention to your body - are your shoulders relaxed? are your forearms relaxed? are you breathing easily? Standing at the bus stop or in a bar by yourself with nothing to do? about to pull out your iphone to check HN? NO - check your posture - feel where your hips are, feel where your head is, drop your shoulders, lift your head gently.....any moment, any time, anywhere you can do some work on your body. How small can you make a movement....can you rotate your hips in such small circles that nobody else notices? Play, explore.

Learn some basic anatomy - the body is to a certain extent, just a set of levers and pulleys - muscles, tendons, bones....those three interact to create movement. Learn the various joints in the body and how they should move. Knowing this alone, you can probably check any exercise you do to make sure you aren't damaging yourself :)

Posture Good posture will not only make you "look" better, but make you feel better - hunching over a desk blahblahblah you know the rest....the best 2 exercises that I've picked up (especially good for people who spend a lot of time sitting) 1) stand with your back against the wall, heels and head touching the wall as well. Gently try to flatten your spine and raise your head. Do this a few times a day for about a minute. 2) find a corner or door frame - position yourself so your spine is on the corner - your shoulders and scapula should be in fresh air. Pull the scapula towards the spine as if you are trying to pinch the corner or doorframe between the two long muscles on either side of your spine (the erector spinae).

Movement Basically movement is fun - if you approach it as fun rather than something you have to do, you'll enjoy exercising....I like to explore how we can move...breaking it down to up, down, left, right, forwards, backwards....then combining them...so do up and backwards together or left and forwards.

Figure out how your joints move. Rotate them, one at a time and all at once. Move slowly and keep awareness on what you are using to move...are you using the minimal amount of effort? are you relaxing muscles that you don't really need to engage to do the movement? play with that it is infinitely entertaining.

Now you want to pick up something heavy and swing it around? Sure why not. Keep the same in mind - minimal amount of effort to accomplish the movement, keep it fun. Do something functional, dig a hole, shovel snow, pitch some hay. Or try http://www.shovelglove.com/ :)

I applied lean methodology to my weight loss problem. I gave about 3 months to everything I tried, ditched the one's that didn't work, kept the one's that did.

Calorie restriction didn't work, low carb did. Eating 6 small meals a day didn't work, fasting did. A lot of cardio didn't work, a mixture of lifting and cardio did. I guess you get the idea.

Awesome! Sounds like you had a very systematic approach to figuring out what works and what didn't. I would be interested in reading more about what you tried and the results you got. Did you capture any interesting data with your experiments?
I regret not having kept that data. But my goal was to add 1kg per month(about 2.8 lbs) to my weight loss. So if something I tried didn't come close to increasing 3kgs after 3 months I ditched it. Of course I left room for decreasing effectiveness of methods I applied earlier.

The sequence of things I tries was something like this: * get active, i.e start using stairs instead of lifts, walk more, sit less (worked) * cut sugar altogether(worked) * start going to gym with a program mixing cardio and lifts(worked) * limit calories(didn't work, couldn't control hunger) * lower carb consumption(worked) * cardio focused workout(didn't work; went back to my original program) * eat 6 small meals(didn't work, made no difference) * fasting(worked)

It was effectively a journey of discovering what my body and mind reacts to.

It's pretty simple really:

Eat plenty of good foods & lift weights and you'll get bigger and stronger.

Eat 500 calories under maintenance and lift weights and you'll lose weight while also getting stronger.

Two things for you to consider:

1. Creating and maintaining routine is the best way you have to reach your fitness goals. This is probably more important than what you eat or how you exercise. Cut out bad habits one-by-one, add good practices slowly, and practice having good health.

2. Every single workout and every single diet has worked for someone - but not all diets and exercise routines will work for you. The problem is that all of our bodies really do respond differently and your job is to be the expert on your body and how it works. Don't get caught up in what everyone else is doing - focus on the results you're getting instead.

This is good advice, but what about non-fitness goals? I think it's helpful to have a systematic approach to all aspects of your life, but figuring out where to start can be difficult.

For instance, if you feel sleepy or sluggish and it's a problem that you'd like to correct, you might be inclined to adjust your sleeping habits. But what if your sluggishness is a function of your eating habits or your mattress quality? I agree that there's no perfect formula that one can follow, but I think it's more of finding a "system" that you can apply to your life to break down the problems and correct them one by one. So, you might call up your area mattress shops with a 30-day return policy and pick one out that suits your budget. Sleep on your new mattress for 30 days and return it if it doesn't produce the desired results. That's body hacking.

Finding the "system" is what intrigues me most about body/fitness hacking (and hacking/technology in general)
