![]() Researchers from Columbia University Medical Center found that the Fitbit, worn either on the hip or wrist, tracked energy expenditure within 3-4 calories, compared to laboratory-based standards. The greatest underestimations? Cycling and stair stepping. The smallest differences were seen in raking and treadmill running. The researchers found the Fitbit to either underestimate or overestimated energy expenditure by 1-25 calories. ![]() A study published in the Journal of Physical Activity and Health compared the Fitbit to a lab-based method for estimation of energy expenditure for various activities during six-minute periods for each. The mode of exercise can play a huge role in accuracy of these monitors. 1Ī closer look at the different models shows that the Fitbit, one of the more popular monitors on the market, seems to be pretty accurate when it comes to measuring energy expenditure. Heart-rate monitors, on the other hand, use equations based on age, height, gender, physical-activity level, and resting heart rate to estimate the number of calories you burn.Īccording to University of Nebraska researchers who examined various fitness monitors (Jawbone, Fitbit, Nike Fuel Band, and Actigraph), accelerometer-based monitors can overestimate or underestimate energy expenditure by 10-15 percent, depending on the monitor. Accelerometer-based monitors, such as the Fitbit, use predictive equations using your body's acceleration in different directions to estimate energy expenditure.
