Fitbits and similar devices are the way to track fitness. However, when it comes to counting calories, they may not be too accurate.
According to a new paper published by a team of Stanford researchers in the Journal of Personalized Medicine, the calorie trackers in these devices were incorrect by a noticeable margin.
Not sure how accurate the Fitbit calorie counter is… 700 down already today?

Such inaccuracies can add up, said Tim Church, professor of preventative medicine at Pennington Biomedical Research Center at Louisiana State University.
PulseOn released a statement to NPR arguing that "the authors may not have properly set all the user parameters on the device," prompting inaccurate readings.
By contrast, heart rate calculations on the devices tested were nearly always accurate; researchers found most were off by only about 5 percent.
