I know--that's what we've always been taught, isn't it? If calories burned is greater than calories consumed then that equals loss.
If the device is 90% accurate and the error is on the side of overestimating calories burned, that would mean you could be burning as much as 10% less than it says (for 2000 calories a day that'd be 200 calories less). Add in the likelihood (for me, at least) that calories consumed are being underestimated since I'm not good about weighing and measuring everything, and the deficit could quickly shrink to little or nothing.
Also, if you add in the extra factors like retaining water from too much sodium, muscles rebuilding after strength training, the body going into starvation mode from eating too little, and probably a dozen other things that can affect our weight and the speed of our weight loss . . . makes me crazy to think about it too much!
