Bodymedia says it syncs with the Garmin but it really doesn't. It just feeds in information from the Garmin on the heart rate data so you can track it in the Bodymedia web interface with the rest of the information. I read on Bodymedia's site that the data it brings in from the Garmin doesn't affect the Bodymedia's calorie calculations.

Is the Garmin HRM that you have one of the ones that will sync with the BodyMedia armband? If so, wouldn't that give you the most accurate burn? Or is it already doing that for you?

I tried lowering my carbs and felt bad and my sports perfomance took a hit. I also was losing lean mass.

It's not that I am not losing I'm losing fat at a slower rate than expected and gaining lean mass, which I am not trying nor need to do. I know my body type gain lean mass easily, but if calories were off/too high that would be one thing that would happen.

I was suspiscious before but when I saw the Garmin's numbers being lower it made me more so.

I have instrumented myself up pretty extensively over the last few years. I ran a bunch of marathons (until I got hurt) and used a Garmin GPS & HRM as well as a Polar HRM to measure calories, miles, etc.

I now use the bodymedia fit core as well.

Bottom line is that most of these devices are within about 10-15% of each other (They are a lot more accurate though than treadmills/ellipticals, etc.)

But I have recently become convinced that the straight up math of calories in vs calories out is not really that accurate. We'd like to think that if we burn more calories than we eat that we'll lose weight. I think chemistry and composition of calories is more important (eg carbs/proteins/fats) and has a factor in your body chemistry equilibrium.

I don't want to geek out on chemistry on the message boards here, but since cutting down on carbs, I've lost weight and inches even though I am eating more calories.....go figure!

I'd recommend reading "Why we get fat" and "The Art and Science of Low Carbohydrate Performance"

Has anyone used the Bodymedia to track calories and compared to another device?

I recently have been using a high end Garmin Heart Rate monitor. The Garmin says I am burning a lot fewer calories than what the Bodymedia says.

For example today on a 6.22 mile trail run, the Garmin says I burned 683 calories, the Bodymedia said 832. I realize anything is just an estimate, but it seems like the difference is always large. On a 12 mile run last weekend the difference was over 300 calories.

Just wondering if anyone else has experienced this?
