Here's a question. I had my RMR tested two ways. One way was the breath test and the other was via the tanita scale. The breath test said my RMR was 708 and the Tanita said 1648. Anyone found that one way was better than the other? There is such a huge difference, I'm not sure which one to use.
Thanks
