What’s a FitBit? It’s a tiny device that you clip to your clothing or carry in your pocket that measures the number of steps you take (really, the movement of your torso), and estimates the number of calories you burn during the day. When plugged into its little base station which is connected to your computer, the data is uploaded to a web site for storage, display, comparison and to be combined with manually entered data about your non-measured activities and what you ate. It only costs $99 and is an incredibly nice piece of engineering and packaging. While the company has sold a load of them, it seems that the early adopters are, not surprisingly, geeks, data junkies and fitness-o-philes. I think I may reside in all three camps and as such, was a relatively early adopter.
I’ve been carrying a FitBit with me for the last 8 months. It is so small and light and the battery lasts so long, that I often forget I have it with me (as I did this week when I went through one of those airport x-ray vision machines used to see if you’ve recently changed your underwear with it on me). Usually, I’m disappointed in the calorie consumption it reports at the end of the day through it’s small display, but that’s the point. It kicks me in the ass so I do less sitting on it. It’s not a FitBit issue, it’s a personal one.
As with many such measuring devices, the absolute data is less important than the relative data. If I consistently burn 2,500 calories per day, I know that a lard-retaining 1,900 calories expended in a day is going to get me in trouble. Especially if I have several of those back-to-back.
When I ordered my FitBit, it was DOA. Well, it wasn’t entirely dead, there was a bunch of garbage on the little on-board display. Resetting (by sticking a paperclip into the tiny hole in the bottom of the base station, FWIW) didn’t help. I sent an email to support which, after sending me a long email asking me to try everything I had already tried, RMA’d the device and sent me a new one. Pretty easy and the right way of doing it.
The only downside to the device is in what it can’t do – measure the activity that doesn’t involve moving my torso. You can do bench presses all day long and register nothing north of the number of calories you would be burning if sleeping. What I’m really waiting for is something that does real time blood testing and can capture all muscle movement and extent. Non-invasively, of course. Until then, though, the FitBit tells me an awful lot about what I’ve been doing and sets the stage for thinking more about healthy living.
