The past two weeks I’ve been trying to set a new stride. It was starting two weeks ago that I moved to part-time at Sapient (3 days a week) which is a big shift and allows me to focus on my idea of starting my own business (more on that in a future post). Anyway, the thought occurred to me recently … wouldn’t it be cool to get back to my pre-Sapient weight. I don’t really know what that number would be but I’d guestimate around 165. Maybe as low as 160? Ultimately the number isn’t the most important thing, it is more about feeling good and having the right gut-to-chest ratio. That said, numbers are good for targets and I’m planning on getting to 165.
In order to help me reach that goal – and also due to a start-up idea I’m researching – I’ve purchased a number pieces of kit that will help me along the way:

Do gadgets help to achieve the goal? I think so. They do for me. They provide feedback and that feedback loop is addictive in itself. Just the other day I played tennis … and I caught myself thinking, “this will be great for my activity goal for today on the FitBit”. In many ways it’s not surprising … it’s been know for a long time that the best way for people to conserve energy at home is for them to have metrics on what devices are using what energy levels. This data informs initially and then through the feedback loop can reward good behaviour more than unmonitored progress.
What Tools are There?
Route Tracking / Running Software
The world of personal sensors is developing quickly but there are already segments that are mature and lots of ready-to-be-used devices out there to help you. Fitness goals like running and cycling have long led the way with their pedometers, GPS watches, cadence sensors, power meters, and community route-tracking sites like RunKeeper and Endomondo. I was always a big fan of the Garmin GPS watches in the past but as I’d misplaced my watch (due to neglect) I have found that these run sites have more than adequate software that runs on your smartphone and does precisely the same thing as the Garmin watch. Regardless of which tools you use when out running, some sort of GPS-based route management software will provide great data for you to analyse your progress.
Activity Monitoring

Activity monitoring is a less familiar category for most people and while it is a relatively new area of self-monitoring it is one of my new favourites and the tech is mature enough for it to work for you immediately. What does it do? It uses an accelerometer to measure motion on a small device that you clip to your body. This then is able to measure activity level throughout the day and give reasonable approximation to steps taken, calories burned, etc. The FitBit is the device I bought but Phillips also makes a device and BodyMedia have made one for several years. Right now these devices are more available in the US then in Europe but I’m sure they’ll be widely available soon. Interestingly, the accelerometer is widely available in all major smart phones too. While this hasn’t yet been taken advantage of yet in terms of a software-on-the-phone solution yet I suspect this is only a matter of time. Although devices like the FitBit will continue to have the advantage of small size that easily attach to clothing at some point it becomes “just another device” and more and more people are already carrying their smartphone everywhere (including during exercise).
Sleep Monitoring
This category is currently dominated by the Zeo Sleep Monitor. The Zeo can monitor actual sleep stages (e.g., REM, light, deep, etc.) and give a very complete report on the quality and amount of sleep you are getting. Sleep is critical for the body in both physical and mental activities. Knowing what’s going on “inside your head” while you sleep is informative and interesting. When combined with other data I am also hoping to see some interesting correlations. I’ve only had it two days so too early to see if that comes true. In addition to the Zeo, most of the Activity monitors from above have a “night time” mode that allows for you to track motion at night and translate that into a rough (although reasonably accurate) guide to when you’re sleeping and when you’re not. It can’t determine what type of sleep you’re in but it does provide useful feedback none-the-less and lowers your cost in getting yourself fully metricized.
Weight / Body Fat Scales
Weight measurement is the most common form of personal sensor and has a normal part of many people’s daily routine for decades. More recently, it has become more common to add a body fat monitor as part of the scale. This measurement – which uses a very small electrical current to measure body fat percentage – is a much better guide to your relative “weight health” than the more crude BMI measurement that has become popular recently. The latest addition is getting the data out of the scale and into “the cloud” where it can be monitored and viewed over different time horizons. The Withings Body Scale is the leading example of all three elements (weight, body fat, networked). I’ve used the Withings for years and it is really helpful in understanding your weight fluctuations over time; the best part is it takes zero effort … just stand on it for about 5 seconds every morning. That’s the sign of a good sensor: interesting data, easily captured.
How Am I Doing?
Well so far … pretty well. I’ve dropped from 185 to 170 over the past few months. Admittedly most of the sensors are more recent but there is a clear increase in my weight loss since I had more metrics to work off of and my interest and motivation are dramatically increased.
