A trend over the last few years is to use fitness trackers to measure calories burned.
Many claim them a useful tool to see calories they have burned and so how much intake they can have and still burn fat.
Researchers at Aberystwyth University found all products – ranging from £20 to £80 in price – were inaccurate during walking and running tests.
Dr Rhys Thatcher said devices had an “inherent tendency” to over-measure.
Brands tried to counter this by saying: “He added the inaccuracies were not important if they were being used as a motivational tool or to track progress.”
Fitbit said it was confident about the performance of its product.
Letscom and Letsfit said their devices depend on data such as height and stride for accuracy and are not scientific devices, giving only estimations.”
Our feelings on said products? Save your money. If you’re burning fat and eating the right amount, you don’t need to spend £80 to see this!
