Anne Wright: Breaking Free of the Tyranny of the Norm

We’ve heard from our friend, and Pittsburgh QS meetup co-organizer, Anne Wright, many times before. She’s a wonderful proponent of the power of self-tracking and using data, research, and continuous exploration to discover and learn about what is meaningful in your life. All of that passion stems from a personal experience with overcoming various health issues. In this talk, presented at the London QS meetup group, Anne talks about how self-tracking played the key role in helping her recover. Anne then goes on to make the case for using self-tracking to learn how to forge your own unique path towards understanding in a world built around the idea of what is normal.

Ellis Bartholomeus on Tracking Food with Photos

At the start of 2013 Ellis Bartholomeus decided to start keep track of her life. Since her friends were always asking about her eating habits (she was a consistent traveler and rarely at home) she decide to start tracking her food. Instead of entering in her food into a calorie counting app she started taking pictures of everything she ate. In this talk, presented at the 2013 Quantified Self Europe Conference, Ellis describes her process and some of the interesting things she learned along the way. I was especially interested to hear how these pictures served to act as “anchors” for other things going on in her life:

It became a great way to remember how I spent my days, where I was, with whom. These pictures are very clear reference, they work like anchors in my memory.  It is very joyful to browse through the month food-wise since dinner and breakfast are so often a social occasions, and I was reminded of great conversations and situation while looking at the picture.

Max Gotzler: A Testosterone and Diet Experiment

Max Gotzler wasn’t feeling his best during a long German winter. He decided to visit his physician to see if anything might be going on. This included various blood and micronutrient tests. When he received his results he noticed that his testosterone levels were on the low end of the acceptable range. Intrigued by this, he set out to figure out what affects his testosterone levels. Using a variety of self-tracking tools and methods he experimented with diet and lifestyle factors while tracking his testosterone values. Watch Max talk about what he found below and make sure to read his responses to our three prime questions.


Slides are also available here.

What did I do?
I explored how diet changes influenced my level of free testosterone. In addition, I observed how changes in testosterone related to my mood, sleep and energy level.

How did I do it?
Over the course of one year, I regularly checked my level of free (active) testosterone in saliva and correlated the results to other data I had collected using apps and tracking devices.

What did I learn?
I learned that eliminating carbs from my diet resulted in lower testosterone and adding carbs together with fat and protein increased testosterone. I also learned that sleep was closely tied to my level of testosterone. After good nights of sleep (usually more than 8 hours), my level was elevated the next morning.

Conference Preview: Bob Troia on Tracking Blood Glucose

We’ve learned a lot from the diabetics in our community, such as Jana Beck’s lessons from 100,000+ blood glucose readings, and Doug Kanter’s narrative visualizations of a year of his diabetes data. At the upcoming QS Europe Conference on May 10th and 11th in Amsterdam, we’re going to hear the interesting story of a non-diabetic who began tracking his fasting glucose to improve his health.

With the US Centers for Disease Control estimating that over a third of the US population shows signs of diabetes or pre-diabetes, it’s not surprising that the techniques of learning from blood glucose measurements are spreading more widely. After learning from his 23andMe profile that he had an elevated risk for developing Type 2 Diabetes, Bob Troia began tracking his fasting glucose daily while also tracking exercise, diet, and  experimenting with supplements. He’s been reporting the results on his blog, Quantified Bob. If you’re curious about how to apply these techniques in our own life, join as at the upcoming meeting, or keep an eye out for the video of Bob’s talk at the New York Quantified Self show&tell.

The 2014 Quantified Self Europe Conference is just a few weeks away. Please join us!

Max Gotzler on Tracking Testosterone and Diet

Max Gotzler was smack dab in the middle of a long Berlin winter and he started experiencing reductions in this mood, energy levels, and sleep.

His prior reading and research led him to experimenting with his diet (primarily with carbohydrates). In this talk, filmed at the Berlin QS Meetup group, Max describes his diet experiments and the results he found over six months of tracking.

Katrina Rodzon on Celiac Discovery

Katrina Rodzon thought she was a relatively healthy person until she realized that seemingly disconnected symptoms pointed towards something real, a gluten intolerance. She took this hunch and decided to test it out using a simple elimination diet along with tracking her weight and subjective bloating and mood ratings. Watch her great talk from our 2013 Global Conference to find out what she learned.

Chris Bartley on Understanding Chronic Fatigue

Chris Bartley worked on land mine removal as part of his undergraduate work, applying data collection and statistics to help with the process of removal. While on a trip for his research he contracted Reiter’s Syndrome. Even after he recovered he still felt like something was wrong. After consulting a physician he started tracking his wellness along with his diet and supplement intake. What follows is an amazing story about what Chris learned when he started applying his knowledge of statistics to his own data.

We’ll be posting videos from our 2013 Global Conference during the next few months. If you’d like see talks like this in person we invite you to join us in Amsterdam for our 2014 Quantified Self Europe Conference on May 10 and 11th.

Doug Kanter: A Year Of Diabetes Data

The complex relationship between behavior and diabetes control has long been a testing ground for gathering and making sense of personal data. Doug Kanter is a Type-1 diabetic who’s been thinking about how self-tracking influences his diabetes control for a few years. While in graduate school at the Interactive Telecommunications Program (ITP) at NYU he started experimenting with visualizations that helped him understand his blood sugar and insulin dosing. In 2012 he began adding more data to his exploration in order to better understand how diet played a role in his diabetes self-management. Watch this great talk to learn more about Doug’s journey and his ongoing Databetes project.

We’ll be posting videos from our 2013 Global Conference during the next few months. If you’d like see talks like this in person we invite you to join us in Amsterdam for our 2014 Quantified Self Europe Conference on May 10 and 11th.
