Found this really interesting blog post (pdf here: Fitbit 11-23-10) from Fitbit’s chief data scientist explaining how steps do not necessarily equate to calories. Will have to check out the two authors mentioned in the post as well…. Of course, I need to figure out how to reliable detect steps first! It had not occurred to me to look for academic research on the the matter, however, so perhaps I should look for some literature on the subject before blinding performing my next analysis.
