Activity monitors that track your exercise movements and count your steps may actually hinder your efforts to lose weight, a recently-published study conducted by the Journal of the American Medical Association (JAMA) revealed. The 500-person experiment had found that dieting adults who were those trackers for 18 months lost around 8 pounds, while those without them weighed around 13 pounds less. The New York Times explains that the results have more to do with “the tangled relationships between exercise, eating, our willpower and our waistlines.” Those wearing the trackers may have been quickly de-motivated when they saw that they hadn’t reached their daily goals, while those without them were able to self-monitor and self-motivate themselves. “People may have focused on the technology and forgotten to focus on their behaviors,” said University of Pittsburgh’s John Jakicic.
