Ceasurile inteligente supraestimează caloriile arse

Smartwatches from Apple, Samsung, and Garmin significantly overestimate calorie burn, with Fitbit being the least accurate. Research indicates that these devices can mislead users, especially those with higher body fat. The study involved participants cycling while wearing different smartwatches and a metabolic analyzer to compare calorie readings. Garmin and Samsung overestimated by up to 25%, while Apple was more accurate. Fitbit showed the largest discrepancies, sometimes reporting implausibly low calorie counts. Experts suggest that users should focus on trends over time rather than daily totals, as the accuracy of calorie measurements varies widely.
