I've had a bodybugg since last Sept. I still wear it daily (except when I'm on vacation!) and log in my food. It definitely feels worth the money, it's a big investment up front and now I pay $9.99/mo. For it to track the calories you eat, you have to enter in your food, which I was doing before I had the bodybugg at WeightWatchers online, so I was already used to that (I've since stopped subscribing to WW online, which was about $15/mo) What I like best about the bodybugg is how it tracks calories burned. I found an old note I wrote last fall after I'd had the bodybugg for 2 weeks that I wrote on facebook, I'll cut and paste it below.
"Down sides:
1) It's buggy to set up with a Mac. Once set up, the only buggy part is that I have to close Safari and re-open it in order to successfully upload information. I couldn't have gotten it set up without the help of my husband, who is tech-savvy. BodyBugg doesn't work with the Firefox browser, but it works with Safari. But even with Safari, for it to work with Snow Leopard OS we had to change a setting on Safari.
2) It's spendy, and there's a monthly subscription fee on top the device. My husband bought this for me as a birthday present, with 6 months subscription, so I'm not really feeling the $ pain, but still, it's a few hundred dollars investment up front. The monthly subscription fee is comparable to my Weight Watchers fee (which I canceled) so once you buy the device, its cost seems comparable to other weight management systems. (And a friend told me that you can find used BodyBuggs on ebay and craigslist, though I haven't looked.)
Things I like: I find their tag line that it "takes all the guesswork out" to be true. I discovered that cooking, practicing cello, and sewing all burn around the same calories as yoga! I had always considered those other activities to be "sedentary". Really, the only thing that burns calories like watching TV is sleeping. TV is the devil! Unless I'm on the treadmill while watching it! I've stepped up my cardio exercise the past couple weeks as a result of BodyBugg feedback.
I like that when you initially set it up, you set your goals and choose how much of a calorie deficit, balance, or surplus you want to shoot for. I've definitely been exercising and moving around more to meet my goals, and it's motivating to upload the information and see a graph of my activity. Obviously I've always known that, for example, walking the dog is healthier than watching TV, but there is something oddly rewarding about seeing my activity on a graph!
Entering what I've eaten is about as easy as Weight Watchers online, once I got the hang of their interface. It gets super easy once you start eating the same meals because it's stored in memory. My morning oatmeal and my fruit smoothies are no-brainers now. And their library of food seems pretty vast. For example, if I enter in "Clif" it comes up with a vast list of every Clif bar product on the market. I click on the bar I ate, and instantly all the nutritional information is logged into my profile.
I appreciate the very detailed nutritional information. Besides just calories, it charts your intake of protein, fat, carbs, cholesterol, saturated fat, fiber, calcium, sodium, and fiber. I love seeing how my vegan diet translates into zero cholesterol intake, crazy high fiber intake, and more than enough protein. And it helped confirm that I will continue taking a calcium supplement everyday, because most days I'm a little low.
Oh, and it's comfortable to wear, I don't notice it."
