PSA: Your watch has no idea how many calories you burn

Your watch ⌚️ doesn’t have a clue how many calories you burn 🔥

•A study published in International Journal of Environmental Research and Public Health, Researchers have found that, five brands of commercially available fitness trackers on average, were reasonably accurate with measuring heart rate, but wildly ineffective at estimating calorie burn 🔥 for energy expenditure.

🤪The scientists found that the wearables overestimated calorie burn by 14 to 23%.

Those findings reinforce a 2017 study at the Stanford School of Medicine, in which researchers looked at seven popular fitness trackers:

•Apple Watch
•Basis Peak
•Fitbit Surge
•Microsoft Band
•Mio Alpha 2
•PulseOn
•Samsung Gear S2

All devices scored poorly, with a medium error range being from a dismal 27.4% for the Fitbit, to shockingly bad 96.2% for the PulseOn.

While these trackers can be useful, You can see if you upped your activity or intensity from the day or week before to gauge your own progress.

But please don’t go trusting these numbers as facts.
