Duane Hewitt gives an update on his 23&Me data and what he’s started doing since he received his results.
Dmitri Gomon describes how he tracked his way to losing 9kg over four months.
Jim gave a brief overview of how and why he’s tracking his Starbucks intake.
It seems that food tracking can have an enormous impact on weight loss and weight control, but counting calories can be difficult. David Sweet was looking to lose weight and wanted to use a system that kept him engaged for a long period of time. He devised a unique system to track his food – the Fist-Sized Volume. Watch this interesting talk, filmed at the New York QS Meetup, to learn how he did it and what he learned (stick around for the great Q&A).
We’ve covered weight tracking here many times. It’s a very popular topic, and one of the easiest ways to get started with self-tracking. In this insightful talk from Matthew Ames we learn how weight tracking, in conjunction with diet and activity tracking, positively impact his weight loss and improved his fitness. (filmed at the Boston QS Meetup).
John Schrom is a data scientist, graduate student, and avid self-tracker. After taking a look at his historical weight data he decided to dig a bit deeper into the story. Luckily, in addition to collecting his weight (via a Withings scale), he’s also been using Foursquare to collect his geolocation history. With these two data sources in hand he asked himself, “What kind of places do I visit when I’m gaining or losing weight?” Watch this great talk talk recored at the Bay Area QS Meetup to learn how he used association rule mining to explore his data, and what he found. When you’re done with the video make sure to go and read his excellent write-up here.
“I was starting to feel a little bit out of control.”
Robert Carlsen used to be an amateur bike racer. When he moved to New York and stopped racing he found that his weight was slowly creeping up. He was still leading an active lifestyle, but he soon realized that most of daily food choices were the result of guess work. In this video, filmed at the New York City QS Meetup, Robert explains how he used different apps and tools to track his caloric inputs and outputs in order to move towards his goal weight.
Some people may be wondering how I find all the amazing people conducting neat self-tracking experiments and creating jaw-dropping personal data visualizations. Well, for the most part I just listen. I’m constantly paying attention to what’s being said on twitter about #QuantifiedSelf. When that doesn’t work I just use the power of Google to find people who are blogging about self-tracking, self-experimentation, or personal data. It’s great to look through the search results and see how many people are sharing their personal stories and insights. While doing some searching this morning I stumbled across a project that immediately brought a smile to my face. Hopefully you’re excited by this as much as I am.
Chris Volinsky is a statistician at AT&T Research and he’s no stranger to handling large data problems. Back in 2008 he was part of the team that won the $1 Million Netflix prize. He also has quite the impressive list of research papers that illustrate the many different uses of cellphone location data. But what is really interesting about Chris is his newest project: My Year of Data
Back in November of 2011 Chris started off a blog entry that with this:
My name is Chris. I am 40 years old. I am 5’9 1/2″ and weigh 174 pounds. I walked 9,048 steps and have consumed 1,406 calories today (so far).
Realizing that he’ld been gaining weight and wasn’t at his optimal health he decided to take a data-centric approach to improving his health. He is a statistician after all. So far, he’s found some interesting things. Take for instance his weight and dietary tracking.
As he explains in this post, Chris typically has a hard time tracking his diet consistently. This can be pretty frustrating when you hear about how important it is to eat this or not eat that to help with weight reduction. Rather than get frustrated Chris turned to the data to see what he could learn. When he stopped looking at the data he was entering and started looking at the missing data an interesting trend lept out. He found that fluctuations in his weight appeared to be correlated with whether or not he was logging food. Take for instance the plot below. It appears that there is a pretty clear association with periods of weight loss and periods of actively logging his food (pink zones). The opposite also appears to be true – no food logging = weight gain.
So this is where a typical NFATW post would stop. We have an interesting finding and a neat data visualization. But, Chris is doing something much more interesting than just talking about his weight data. He is on a long-term self-tracking and self-discovery journey and he is trying to enlist other interested parties to help him. Chris is going the extra step and posting all of his self-tracking data online for anyone to analyze, visualize, or just get inspired.
You can access all of his amazing data via a public dropbox folder that he’s set up. He even has a nice README file explaining the datasets and formats. So far he’s sharing the following:
- Fitbit: sleep and activity data
- FitLinxx: weight training data from gym activities
- Livestrong: dietary tracking data
- Runkeeper: running and other exercise activity data
- RescueTime: productivity tracking (computer/internet use)
All the data is open and available for you to play with. This should be a really interesting project to keep “track” of in the future (pun definitely intended). To help inspire some action on your part I took some time today and looked at Chris’s most recent available data to see what I could find out. I downloaded his Fitbit data and decided to look for any interesting patterns. Turns out that when taking a look at his daily patterns of activity there seems to be something going on on Thursdays that reduces his step count and activity time . Also, Saturday is by far the best day with an average of 9,862.56 steps and a 5.3 hours spent being active (data available here).
Make sure to reach out to Chris over at his blog and take a took at his data to see what interesting thing you can figure out!
Every few weeks be on the lookout for new posts profiling interesting individuals and their data. If you have an interesting story or link to share leave a comment or contact the author here.
At a QS Meetup in San Francisco about a year ago, I ran into a friend I hadn’t seen in over 15 years. Imagine my surprise when I discovered that he had quietly built one of the most widely used weight loss tools: MyFitnessPal (with 170,000 ratings on the AppStore, mostly 5s!). Mike Lee explains the focus, passion and patience it has taken to do this.
Q: How do you describe MyFitnessPal? What is it?
Lee: MyFitnessPal is a calorie counter that allows you to easily track your diet and exercise to learn more about what you are eating and how many calories you are consuming and burning. We have a website as well as mobile apps on every major platform, all of which seamlessly sync with one another so you can log at your computer or on your phone, whichever is most convenient. We also provide a variety of social networking tools so that you can easily motivate and receive support from friends and family, as well as stay informed of each other’s progress.
Q: What’s the back story? What led to it?
Lee: In 2005 my wife and I wanted to lose weight before our wedding. We went to see a trainer at 24 Hour Fitness, and he suggested that we count calories. He gave us a small book that had calorie counts for about 3,000 foods in it, and told us to write down everything that we ate. Being a tech guy, there was no way I was going to do this on paper, so I immediately threw the book away and looked for an online solution. There were already tons of online calorie counters available — I probably tried at least 15 myself — but to my amazement, none of them worked the way I thought they should work. They were all incredibly hard to use; I actually found it easier to track on paper than online. I was looking for a new project to work on, so I decided to write my own calorie counter — that’s how MyFitnessPal was born.
Soon my brother joined me. We’ve kept the team very small, while slowly building up a loyal following. We passed a million users a few years ago, and are still growing very rapidly.
Q: What impact has it had? What have you heard from users?
Lee: One of the best parts about working at MyFitnessPal is the messages we get from our users. I’d estimate that anywhere from 30-50% of the emails that we get are from people simply telling us how much they love the app, and how much it’s helped them lead a healthier life. People write in telling us that they’ve been trying to lose weight for 20 years, but nothing had worked until they tried MyFitnessPal. We hear from people who’ve been able to cancel surgeries, stop taking medications, fit into jeans they haven’t worn in years, or even things as simple as just being able to stand up without using their arms to push themselves up. We have thousands and thousands of members who’ve lost 100 pounds or more. We’ve even had people get married after meeting on MyFitnessPal.
It’s hard to generalize users’ experiences because we have so many users. And they vary widely: there are people who’ve never exercised, who would find a 15 minute walk difficult, and we have professional body builders.
Still, one thing stands out, which is that the biggest benefit is education. It’s amazing how little most people know about what they eat or the activities they perform, and once they start using the app, it’s eye-opening. They discover what they eat, how much, how often, the nutritional content of the food, and the impact of physical activity. They build up knowledge that stays with them even if they stop logging their foods. With this knowledge they can make their own decisions about what to change in their lives, what trade-offs are best for them. It’s not following some diet fad, but discovering what works for you.
Q: What makes it different, sets it apart?
Lee: We really pay little attention to other apps or the media. Rather we’re fanatically focused on our own users. We listen deeply to user feedback, but we don’t just do what they ask for. Instead we try to understand their real problem, and focus our work on the things that we’ve discovered really matter for losing weight.
We know losing weight is really hard and that tracking is a pain-in-the-neck. So, we really work hard to make our site and our app as easy to use as possible. We know that the easier and faster we can make logging your foods, the more likely you are to stick with it, and consequently, the more likely you are to reach your goals. As a tool maker, it’s our job to help make that process as easy as possible and remove every barrier we can to your success. I can’t really point to anything in particular about ease-of-use; it’s just something we focus on relentlessly and something that the team is just good at.
Q: What are you doing next? How do you see MyFitnessPal evolving?
Lee: Over the past year, we’ve worked hard on expanding the number of platforms on which MyFItnessPal is available. We’ve released apps for Blackberry, Windows Phone 7, and iPad. Though they are similar, the interfaces are tailored for each platform. Now that we’re available on most major platforms, we’ll be spending more time on improving our core logging tools. We’ve got a ton of ideas on how we can make calorie counting even faster and easier, so hopefully you’ll be seeing a lot of improvements in that area from us in 2012.
Q: Anything else you’d like to say?

Alex Chernavsky has kindly given me several years of weight data he collected by weighing himself daily. He read about the Shangri-La Diet in 2005 and several years later decided to try it. The graph above shows what happened: Starting at 222 pounds (BMI = 32), over 11 months he lost 31 pounds, reaching a BMI of 27. Since then — while continuing the diet — his weight has increased at roughly the same rate it was increasing before he started the diet.
He started by drinking olive oil and sugar water, switched to olive oil alone, and then, finally, to flaxseed oil alone of which he drinks 3.5 tablespoons/day (= 420 calories/day). He does not clip his nose shut when he drinks it but he washes his mouth with water afterwards. More about his method here.
Almost all weight-control experts would say these results are impossible: 1. Alex lost weight because he ate more fat. Fat is fattening say most nutrition experts. 2. Atkins dieters, who don’t say that, think the secret of weight loss is to reduce carbohydrate. Alex didn’t do that (and eats plenty of carbohydrate). 3. He didn’t restrict what he ate in any way. 4. He didn’t change how much he exercised.
Quite apart from how it contradicts mainstream beliefs, including Atkins, the data are remarkable because the change was so simple, small, and sustainable, the weight loss so large, the rebound so minimal, and data period so long.
An ordinary clinical trial has obvious advantages over such one-person data, such as more subjects and more data per subject. Less obvious are the advantages of this sort of data over clinical trials:
I’ve been thinking for some time about the connection between self-tracking and mindfulness. At first glance they seem to be very different – picture the wired-up gadget wizard sitting next to the unadorned meditating guru. But step to the side and look from a different angle, and you may see meditation and self-tracking as two parallel tools that lead down the same path toward mindfulness.
While these thoughts were swirling through my mind, I got an email from Alex Pang. Alex is a futurist currently housed at Microsoft Research Cambridge, where he is studying the relationship between self-tracking/self-experimentation and mindfulness in a project he calls “contemplative computing”. Wow. Alex just finished writing an article on this topic, using his own experience with weight loss as an example, and delving both into the past and into the future to come to some interesting conclusions. His paper is available here, and I’d love to know if anyone else out there has been thinking about this connection as well.
Maybe the modern-day version of the gong and the meditation cushion are the self-tracking app and the device that runs it?
Fellow QS Show&Tell member, lifestyle experimentalist, and tango king Tim Ferriss recently wrote an astounding blog post on rapid weight loss through manipulating kidney function – dehydrating and rehydrating. He did not actually lose the weight for a tango competition. Tango – in case you were wondering – does not generally classify competitors by weight. However, in 1999, Tim won a major Sanshou (Chinese kickboxing) championship:
I arrived the on-site at 187 lbs., weighed in at 165 lbs., and stepped
on the platform to compete the next morning weighing 193 lbs.
I remember my friends in high school and college who were wrestlers used to engage in what seemed like insane weight-loss programs in order to qualify for competition, but nothing they did resembles what Tim describes. Competition drives innovation, and rewards risk – sometimes fatally, as Tim points out. But because extreme training has such high stakes, it is also a proving ground for techniques of self-monitoring and self-exerimentation. (Our interview with pseudonymous trainer “Phineas” about anabolic steroids covered adjacent territory.) Tim’s account of rapid weight loss is an eye-opener.
