Are your daily activity levels (moderate and vigorous) about the same as they've always been? I know I have days when I think I've been about as "busy" as I normally am but the BMF shows that I was actually more active than normal (resulting in a higher calorie burn).

It could be a glitch, I suppose, or you could have just spent more time on your feet and active but not really walking. I have days like that, where I think my routine was pretty much the same but I had a much higher burn. But, if I really think about the day, I maybe spent an extra hour in the kitchen baking or doing dishes, crawled around the floor picking up stuff a bit more than usual, etc. and it all adds up.

I have also worn my BMF band and Fitbit Zip simultaneously for about 3 months. While my BMF usually registers a higher burn than my Zip (about 250-400 more), on the very rare occasion that I am almost completely sedentary outside of my AM workout, they are within 50-100 calories of each other. Than means the BMF is registering all the non-step based activity that the Fitbit misses. So, if you see a big difference, this could be it.

I would gather data over a longer period of time before you decide if the BMF is broken or if you really were more active on those days (even if it was just standing up vs. sitting!).

I have the core armband and display. What I have noticed is that the Activity Manager and display don't match, not since last week. The display is still showing me what I assume to be the correct numbers. If I walk for 30 minutes the display shows around 30 minutes of moderate activity. The activity manager will show some ridiculous number, like 3 hours of moderate activity. The vigorous activity still seems to be showing up accurately.

I have contacted customer support, they answered saying they are aware and working on it, but it hasn't changed. I contacted them on Friday.

I urge everyone to contact them and tell them of the problem. We pay a subscription to the website so we have a right to expect it to work. Of course occasional problems are understandable, but they should be fixed in a timely fashion.

This morning I got up, fed my dog and got myself a cup of coffee, according to the activity manager that gave me 10 minutes of moderate activity. According to the display it didn't give me any activity.

I believe the display is correct, because I've been using the device for a long time, and the numbers I've been getting have resulted in the expected weight loss, its only in the last week that the activity manager doesn't match up to the correct numbers on the display.

I have disconnected MFP from bodymedia, and now I'm using the display on "trip" to tell me what I've burned in exercise, and I'm entering that number myself so that bodymedia doesn't give me more calories to eat automatically. However, I am getting a little ticked that they aren't fixing this issue.

This is the response I got to my inquiry about the unusual higher burn:


"On March 4th we made some improvements to the system. Because of these improvements, you may notice an more accurate, but slightly higher calorie burn than you are used to seeing.
If you use a display monitor, you notice differences between the display and Activity Manager. When you sync your data in the Activity Manager, it provides a more accurate and processed analysis of the data as the dispay has a much more abreviated version of the algorithms.

With the recent improvements to our algorithms you may need to adjust your MET's values to better show your energy expenditure.

You can do this through the Settings/Preference portion of the activity manager. Here you will go to the Physical Activity Level and adjust you numbers appropriately. Please let me know if this correction better shows your activity."


So then does this mean I need to lower my MET value or increase it?
