Fitness trackers are largely inaccurate when counting calories, Stanford researchers say - The Washington Post

'Calorie counting is a useful way to lose weight, but a new study suggests a fitness tracker could sabotage your efforts. '

'A team of Stanford researchers, however, recently called foul after testing these trackers. '

'A multiyear study published last September in JAMA split into two groups almost 500 people hoping to lose weight. '

'For instance, since its inception, the leading brand, Fitbit, has sold at least 30 million of them. '

'In this scenario, that’s 1,890 extra calories each week the users don’t know about. '
