A study from the Stanford University School of Medicine revealed that popular smartwatches, including the Apple Watch, are not accurate in tracking calorie expenditure. Researchers found that even the most accurate device was off by 27% compared to medical-grade equipment, with others being as much as 93% inaccurate. The inaccuracies stem from the difficulty in measuring metabolism directly from the wrist, forcing devices to rely on proxy data like heart rate and motion, which are insufficient for precise calorie counting.
