“Wearable devices that monitor physical activity are not reliable tools for weight loss, says a new study from the University of Pittsburgh School of Education’s Department of Health and Physical Activity. The study specifically investigated whether regular use of commercially available activity trackers is effective for producing and sustaining weight loss.
At the conclusion of a 24-month trial, researchers observed that usage of a wearable device in combination with a behavioral weight loss program resulted in less weight loss when compared to those receiving only the behavioral weight loss program. In fact, participants without physical activity trackers showed nearly twice the weight loss benefits at the end of the 24 months. Participants who utilized wearable devices reported an average weight loss of 7.7 pounds, while those who partook only in health counseling reported an average loss of 13 pounds.”
