Please don't feel defeated by looking at that number; it's just a suggestion, nothing more, and you're still going to lose weight even if you don't meet it.
I have been using my BodyBugg for about a week and a half, and I am generally burning above 2500 calories/day on the days I go to the gym. When at the gym I typically do either cardio (in the form of either the eliptical or jogging on the treadmill) for ~45 minutes, or I do strength training for about 40 minutes, stretching, and then 25 minutes of cardio (stationary bike). On the two day since having the Bugg that I have worked out at/around home (25 minute run outside, or 35 minutes of body weight strength exercises), I have still burned around 2400 calories. The one day in the last week and a half when I did not exercise I still burned ~2000 calories, and I'm a pretty sedentary person aside from the time I devote to exercise.
A few things someone who has been using the Bugg for a long time mentioned to me: you likely won't get an accurate measurement of your calorie burn when doing weight training or something like a bike, as the Bugg doesn't detect that kind of movement as well as other types. At her suggestion, I keep my monitor on my arm (tricep) when I'm doing upper body weight training but move it to my calf for lower body strength training, and I also wear it on my calf for the eliptical and for the stationary bike. For running, I keep it on my arm.
Let us know how things went your first day wearing it, and what kind of calorie burn you're seeing with and without exercise. Hope things go well!
