Jules, there is a way to turn off the negetive calorie adjustment, but for I can not find it right now, which is discouraging because I remember seeing it yesterday. I believe it shows negative when MFP give you more calories for a workout than the fitbit does (at least that is how I understand it). Its to keep you from counting exercise calories twice.

I was looking into getting a fitbit, but I'm torn. Do you ladies recommend it? Usually I just go by the calorie counter on the gym equipment, but as the weather improves I'm hoping to get outside more so that's why I was considering it. I'd also like to see how much activity I do on a normal daily basis. Which ones do you have & why do you like/not like it? Thanks for the input!!

I love my Fitbit. I have a Fitbit One and can wear it almost anywhere, my favorite spot is clipped to the center of my bra (that way there is no bulge under the shirt). The drawback to the Fitbit as with most devices is that it doesn't track all activities with cycling being the most prominent. You can manually enter that info into your log so there is a workaround. You can get obsessed though; last night I found myself taking a late evening power walk because I felt that I hadn't burned enough calories!
