Most Microsoft Band owners use one or more of the integrations provided. Honestly, I use all of them available. Not sure why, but it’s one of those “just in case” scenarios, I guess. My mainstay right now, though, is MapMyFitness for a number of reasons.
However, a lot of you use the MyFitnessPal for tracking food in addition to allowing the Microsoft Band integration to manage your calorie burn information. If so, you might be seeing something like the following and wondering what the heck is going on…
The Microsoft Health Calorie Adjustment is a MyFitnessPal “feature.” It’s a setting within MyFitnessPal you can turn on and off. The actual feature is called Negative Calorie Adjustments.
Per MyFitnessPal, enabling Negative Calorie Adjustments will give you the most accurate information about your calorie expenditure for the day. A negative calorie adjustment indicates that you are using fewer calories on a given day than our original MyFitnessPal estimate.
MyFitnessPal also provides recommendations for using this feature, which includes how often you wear your Microsoft, how often is syncs its data, and whether or not you want your calorie expenditure to be accurate (which is highly subjective).
Check out the information to decide what to do: Should I turn on Negative Calorie Adjustments?
Personally, I just turn it off. There’s a long list of threads in both the MyFitnessPal and UserVoice forums where the calculations for negative adjustments can get out of hand and produce widely erroneous and ridiculous values.
