Why Self-Experimentation Matters

By Mark Sisson
114 Comments

Self-experimentation is a term the online Primal community regularly bandies about. I’ve been meaning to write a post on the subject, and I figured the first week of this year’s Primal challenge would be the perfect spot to drop it. Because, after all, those who accept and undertake the 30-day Primal Blueprint Challenge will essentially be conducting a 30-day self-experiment on themselves. It won’t be your first self-experiment, nor will it be your last, but it may be your first chance at knowingly conducting one.

Yeah, we’re all lifetime self-experimenters, when you get down to it. From infancy onward, we conduct experiments – most of them totally informal – to understand how the world works and how to interact with it. A toddler trying avocado is testing whether it tastes good and nourishes, the teen using a cheesy pickup line is testing whether it gets the girl’s number, and the college freshman pulling an all-nighter before a midterm is testing whether she can party all quarter and still make grades. They’re all forays into the relative unknown, and they’re all crude, imperfect modes of self-experimentation, even though the experimenters probably aren’t consciously aware of any experiments being conducted. Life is full of these informal little tests.

So we have a legacy of experimentation.

But it’s hard to derive lasting value from informal, incidental, everyday self-experimentation. No, if you really want to step up your game and approach discovering cause-and-effect from self-experimenting, be a little more rigorous with your approach. Think of the experiment as an actual scientific experiment, with observation and hypothesis and testing and even recording of data, controlling of variables, and randomization. You’re probably familiar with Seth Roberts, who I’ve referenced before and who gave a great talk at the AHS about his self-experimentation with flax, pork fat, and butter (check it out if you haven’t). Seth quantifies the results of his tests. He measures, records, tracks, and graphs. It sounds rigorous but he keeps the design of his experiments very simple and because of that, his results are fairly conclusive. As a recent Chris Masterjohn post explains, self-experiments conducted in this fashion are necessary to conclusively identify cause-and-effect, but they may not be required for the average Joe who wants to figure out how he feels trying something different.

There’s another way, one that doesn’t require that you bust out charts and stats and take measurements if you don’t want to. For the average person who just wants to play around with new stuff, I like what I call “soft self-experimentation” because it doesn’t require agonizing rigor to obtain useful information. You just do something different – add a food, remove a food, go for morning walks, lift using unilateral movements instead of bilateral movements, whatever it is – and “see how you feel” while trying to keep the other stuff constant (don’t change your sleep habits if you’re trying to test how you tolerate starch). My friend Richard Nikoley of Free the Animal is an expert at this (and gave his AHS talk on the subject) kind of intuitive experimentation. You won’t really hear him talk about numbers (besides maybe pounds lost and lifted), but he does account for confounding variables. Perhaps the biggest potentially confounding variable is bias. That is, your own bias. You have to be honest with yourself and be open to falsifying your hypothesis. In fact, you have to actively look for falsification. Sometimes (heck, many times) you will be wrong and it won’t work out. That’s okay, because that’s how you learn. “No failure, only feedback,” as Art Devany says.

I mean, you’re busy people with families, jobs, and hobbies, and the last you want to be doing is submitting your little self-study about cold showers and fat loss to peer review before you can draw conclusions, or run numbers and graphs. Heck, you barely have time to keep up with the blogs, let alone follow all the references to studies telling you how changing a variable affected a group of people who were not you. And that’s the rub, isn’t it? The scientific literature, however crucial for furthering our understanding of the way the world works, tells the story of other people. Other individuals. PubMed abstracts or full texts you read on your laptop cannot and never will compete with the primacy of actual self experience, because that’s how biological organisms work. The thing that happens to you carries more weight than the thing that happens to another (let alone a nameless, faceless stranger).

And so we experiment on ourselves to figure out what works.

For guidance on how to set up a self-experiment and track your results, check out Seth’s advice.

A few more tips:

  • Keep it simple. Stick to changing one thing at a time, and make it easy to follow.
  • Be specific. Don’t test how “fruit” affects you post-workout. Test how “bananas” or “mangos” or “blueberries” affect you.
  • Kill multiple birds with one stone, if possible. If you’re testing how post-workout bananas affect fat loss or gain, consider observing other possible effects, like improved performance or blood sugar readings. You don’t have to, but keep an open mind.
  • Start with a sensible premise drawn from reliable sources. Like your own experience, another’s, or results from clinical studies. An example: you forget to eat breakfast and feel stronger during the afternoon lifting session. Was it the lack of breakfast? Maybe; test it.
  • Eliminate outlandish premises. I wouldn’t advise testing whether the trans-fats in Crisco are actually harmful by eating a tablespoon every morning, and breatharianism almost assuredly won’t work; the literature is quite consistent.
  • Be prepared to discard a hypothesis. Things won’t always work. And things that seemed to work for a while might suddenly stop working. Or, things that seem to work won’t actually work, or they’ll be working for entirely different reasons than you supposed. In other words, you’re probably never going to know with absolute certainty that something is working for the reason you thought it was. Just be ready to ditch failed hypotheses and change them on the fly.
  • Don’t extrapolate to others. Just as your experiences didn’t jibe with results from randomized controlled trials, the solutions you discovered from your own experiments may not always work for other people. They’ll have to test it on themselves.
  • The beauty of the self-experiment is that it acknowledges the persuasive power of personal experience. Ultimately, we are all interested in leading healthy, happy, and productive lives, so we want whatever works. And while studies on other people are valuable, your own reaction to grass-fed butter always trumps what your cardiologist says the studies about other people’s reactions to butter are. The working mother of three, for example, isn’t going to truly know what works for her until she actually tries some stuff out. Conducting a self-experiment, even if it’s totally casual and would never pass the muster of peer review, gives that mother valuable insight into what works and what does not. And it’s easy, free, and gets the mind working.

The possibilities for experiments are virtually endless…

  • The effect of sleep duration on next day sprint/lifting/running performance.
  • Tolerance of Primal starch source (choose one).
  • The effect of evening laptop abstinence on various markers (sexual performance, sleep duration, next day mood).
  • The effect of a daily “forest bathing” hour-long session.

So, readers, tell me: what self-experiment are you going to conduct?

My self-experiment this week is a standing desk! I modified my desk easily with leftover office junk. It’s not pretty, but it works and can be switched between seated and standing pretty easily. I’m keeping a document with my feelings/observations and my total times sitting vs. standing during the day.

That sounds very interesting!! I sit at my desk a lot during the day- You have given me another idea for experimentation ( thank you)- I may need to just stand and squat a few times while reading my course modules for school then I can sit and do some arm exercises!

I raised my desk with cheap concrete blocks from Home Depot. Works great. I also have a table I sit at to write, draw ideas, or read on my laptop PC, so I am constantly changing positions throughout the day, with probably <25% of the time spent sitting. It's pretty much ideal for me.

Now if I could just punch a hole in the ceiling and get some damn sunlight in here…

This is why MDA is my fav blog (2nd being gnolls.org). mark gave us a platform but it’s up to us to make it personal. I think he’s said this about 100 times just in different ways. There are no hard and fast rules. You HAVE to find what works for you. It took me a year to be able to IF, now I’ve found out(thru experiment) that I feel fantastic if I go all day without food and eat a fairly sizable dinner between 6-9pm. But I don’t always. In fact I’m eating leftover steak right now. What? I… Read more »

I am a sophomore in college and a member of ROTC. I ran cross-country, wrestled, and rock climbed in highschool and I always felt like I was in pretty good shape. Maybe I was, but I had to work my ass off to get there. For the APFT (Army Physical Fitness Test) we are required to do push ups, sit ups, and a two mile run, but after reading the Primal Blueprint I cannot stand how ridiculous these events are as a measure of “fitness”. This summer I decieded that I was going to intentionally not train for the APFT.… Read more »

I changed my diet to a primal diet and began changing my lifestyle. In particular I stopped running long runs and began doing short intervals and some bodyweight exercises. I have not kept up with the primal fitness plan, but I have not run that much, if anything. About 5 weeks after I began following the primal blueprint I ran a 10K. Since I had not run, I wasn’t sure how I was going to do. It was not bad at all. My time was a minute faster than last summer at the same race, but with less running. I… Read more »

You did what many of us have been doing for a long time. The Army is only recently shifting with the new PRT and upcoming changes to the APFT. The change won’t be as drastic as many would like, but you can always choose what physical activity you do when not engaged in Army PT.

I have been self experimenting a lot lately. I’ve never really finished an experiment but at least I am starting them. I have yet to find that one variable that I want to test but I will find it soon. Large studies MIGHT help but when it comes down to it all individuals must do what they feel is best for them. They must try something and be completely honest with themselves. I strongly believe that millions of people become a vegetarian because they think it improves their health. It does NOT but they aren’t honest with themselves and practice… Read more »

My self experiment for the 30 day challenge is to see how much activity I can do each day. Before the challenge I didn’t do much in the workout arena. I am testing to see how far I can push myself on a daily basis. I am 5’2 and 208 pounds. I have to admit it is hard to move around or do certain exercises… so I improvise! I am sure a lot of this will happen until more of the weight comes off but each day is going to be figuring out how do certain exercises like push ups… Read more »

As usual, you accurately describe an important task in our overall improvement. Without self experimentation we become stale, for the lack of a better word. Failure to self experiment may not equate to an automatic weight gain or the creation of some other tangible health concern; but it does mean we fail to take advantage of the malleability of our brain, which to me is quite unhealthy. a good post.

“Don’t extrapolate to others.” So true. What works for us doesn’t not necessarily work for others for a variety of reasons.

I am doing a 30 Day Challenge going no-dairy. It has been a revelation. It feels so freeing and relieving to have it confirmed by others what I have intuitively noticed over the years that what is going on for me is special to me and that because this or that doesn’t work doesn’t mean I am going mad.

Oof, I know my dairy days are numbered based on the amount I eat and crave. Not quite ready to plunge into the 30-day challenge but I am inspired by yours—freedom sounds fantastic.

and good point to emphasize and remember the extrapolating philosophy.

I’ve been experimenting with different starchy foods and it’s effect on my blood sugar levels. I bought a meter and was quite surprised. Carrots and beets (considered quite starchy vegetables) didn’t really effect it much more than a protein only dinner, but adding only a small potato to the plate gave me a serious spike, which took a while to come down again.

Too bad, ’cause I do really like potatoes and had hoped I could sneak some into my diet every now and then. Guess not…

Actually, you are mistaken. Carrots and beets, while high in carbs, are not considered starchy vegetables. Potatoes, yams, yucca etc. are starchy vegetables.

I am going to continue my experimentation with my children. Yikes! I know! I pretty much have down what sets my blood sugar/mood off, but getting theirs in line is another story. So bananas today, maybe sweet potatoes tomorrow…and the attitude results are tell tale signs (yes I know there are other influences especially amount of sleep and outside activity). My oldest loves to experiment, so we will turn it into a science/math lesson. Such fun. Thanks Mark!

Since discovering PB, I’ve been self-experimenting on a daily/weekly basis. Finding that the inclusion of a piece of bread after 20+ days without makes me bloaty…that cooler showers mean that I’m not freezing when I leave the tub…that I’m not quite ready for the 2 mile walk in bare feet, yet. You CAN check more than one variable at a time, just make sure that they are in different arenas — Don’t try to check how 2 or 3 different foods make you feel at once.

The best self experiment I ever did was going off gluten about a year ago. Have never felt better or stronger in my life!

My loose self experiment this week has been less dairy than I have been eating. I’m hoping my skin will clear up more, and some random digestion issues will go away. So far it’s been going well, but I haven’t been keeping any sort of journal or records.

Katie– I recently stopped drinking coffee and my skin cleared up immediately! I haven’t gotten a zit since. Like Mark said, it’s different for everyone, but I tried giving up dairy for the same reason and saw no effect, so maybe something new to try if you don’t get any results.

I’m experimenting with long walks, instead of shorter interval runs. It’s always fun to experiment — following the primal blueprint was my experiment for the month of June. Ha! The results were so overwhelmingly positive that I can’t imagine deviating ever from this approach. Going primal was the best “self-experiment” ever!!

I agree completely with this post. After reading Dr. Bernstein’s Diabetes Solution, the “take away” was that you can get your blood sugar under control my making yourself your own science experiment.

By reducing carbs, and sticking with meat and fresh veggies, I have lost weight and and reduced my A1C to 6.5.

The next experiment is to start exercising and to see its effects on my sugar levels and weight.

If you’re starting the Challenge for whatever reason, keep a food and symptom log! It’s confusing enough at first just to figure out what to eat. Keeping track of aches, pains, and other complaints in a meticulous fashion feels obsessive at times, but it pays off. In January I was suffering from hypercholesterolemia, high LDL, hypothyroidism, and ulcerative colitis on a downhill course. Metamucil was bringing my LDL down, but killing my colon. The Primal Blueprint made sense to me, and having been gluten-free for 5 years it was no problem to give up grains entirely. The sat fat intake… Read more »

My experience and my husband’s has been similar Nannsi. When we started the primal lifestyle, we started charting our weight. It became easier over time to see which meals were affecting our weight and which weren’t. Granted, as Mark pointed out recently, that weight is a very crude measurement, but it worked well for us for general purposes. We both have a really good sense of which foods makes us gain weight and which foods don’t. We also noted how we felt after certain foods. I can’t handle milk while my husband can.

It’s absolutely amazing that this post came in today. Well, yesterday. Yesterday I had lunch with my friend KJ. KJ was a vegetarian for 20 years, got REALLY sick, and realized that her body could not absorb B12 or Iron from pills. So she started eating meat again. She was still plagued with constant hunger, tiredness, and weight gain. Her doctor said “if it doesn’t grow, don’t eat it”. So she started eating primal/paleo. No grains or beans. I watched her eat on a business trip. She told me that she felt much better. So then I borrowed The PRimal… Read more »

Great article! Self-experimentation is a massive interest of mine, ignited by Tim Ferriss in the beginning with his Geak-to-Freak stuff.

Today is the final day of my BarStarzz / Charles Armstrong Pull-Up experiment…

The questions that I can now answer..

1. Did my pull-up reps increase?
2. Did I build some juicy lats and chest?
3. How does 5 days on / 2 days off feel?

I’m posting the results up on my site next week.
