So, I bought a Fitbit. Check out the very good website for lots more detailed info, but in short: the Fitbit is a little clip-on device, about the size of a USB thumb drive, that you wear (nearly) 24 hours a day. It has an accelerometer inside (like what makes the Wii controllers work), and it keeps track of how active you are, how many steps you’re taking, and how many calories you’re burning.
It uploads all that data to a web server, where you can access it on a very well-designed (even though there’s some Flash involved) dashboard. Here, you can also enter what you ate to track your calories consumed, as well as entering specific activities (like swimming or showering, which you can’t wear your Fitbit for; or biking, which it’s not so good at tracking).
So far I like it a lot. It’s very small and convenient. During the day, I wear it clipped to the center of the front of my bra. It’s quite secure there and I never worry about it slipping off; plus it’s well-hidden. When I first got it, I wore it on the waistband of my underpants or sometimes my jeans, but then I had to worry about it every time I went to the bathroom etc. Front of bra is better, but you can also wear it on a bra strap, in your pocket, or on your belt (it comes with a belt clip for thicker belts). At night, I wear it in the soft cuff that was included, and where they recommend putting it for sleeping.
I think it’s too early for me to say whether I think it’s a really helpful tool in weight loss or fitness. I know my first week, I was pleased with how active I was (it really brought home to me how everyday activities also burn calories, not just going to the gym). I was burning about 500 calories less a day than I was consuming, and anyone familiar with dieting will know that should result in about a pound of weight loss in one week’s time (5oo calorie deficit per day x 7 days = 3500 calories, you must expend 3500 calories more than you eat to lose one pound). Unfortunately, I weighed myself the following Monday and had gained two pounds.
WHAT?!?
Well, as it turns out, I was retaining water or something on Monday, because when I weighed myself on Tuesday it turned out that I actually had lost about a half pound. But still, that morning weigh-in was a little discouraging. Which is why I want to wear the Fitbit longer and collect more data before I start drawing any conclusions about its effectiveness as a tool for improving fitness and health.
One thing that is VERY enlightening for me already is the sleep monitor. Let’s take a look at how I slept last night:
Not bad. About seven and a half hours, which is a little less than ideal for me, but there were few interruptions, which means it was restful (efficient) and that’s why it was easy for me to get up at 6am (aka “buttcrack of dawn”) this morning.
Compare that to the night of May 2-3:

Quite a difference. Although my sleep “efficiency” is still in the 90s, and I still got about seven and a half hours of sleep, I can tell you I felt a lot different on the morning of May 3 than I did this morning, and it’s easy to see why. I woke up, at least partially, 21 times that night. Ouch.
So in this respect, so far the Fitbit is very helpful in showing me why I feel like crap some mornings, and not so much like crap other mornings! One change I’ve made because of this is, I’ve pretty much stopped taking Advil PM before I go to bed, and I’m sleeping better because of it. While my broken arm was still healing, I really needed it, but since my arm is mostly better I was still taking it on weeknights because it helps me fall asleep so quickly. The problem is, I tend to wake up more in the middle of the night when I have taken it, than when I don’t. Why? I have no idea, but the proof is there.
More updates on the Fitbit as I use it longer. But now for the bad news.
If, after reading this, you’re convinced that the Fitbit is the greatest thing since sliced whole-wheat bread, and you just HAVE to have one, I have something discouraging to tell you: it takes FOREVER to get one. They are so back-ordered it’s not even funny. I ordered mine on January 11, 2010. I received it on May 1. Yep, that’s almost four months of waiting, four months of my “expected ship date” being pushed back farther and farther. Every time I’d log into the website to look at my order status, there would be a new, later “expected ship date” and I’d get more frustrated!
All that being said, I do think it was worth it, especially for the price, which is extremely reasonable ($99 plus shipping). But be prepared to wait, and wait, and then wait some more. Unless you go to eBay, where you can take your chances and pay $150 or more for one.
Note to the FTC: I did not receive a Fitbit for free (if only!!). I paid for it all by myself and this review is only my opinion.
