Fitness trackers have become a popular way to help people get fit, but are they actually working?

According to experts, not really. Researchers at the University of Pittsburgh gave dozens of overweight and obese young adults in one group fitness trackers, and a control group without trackers. All of the participants went on a low calorie diets, exercised, and worked with counselors. Researchers found the trackers didn't lead to greater weight loss.

"It's possible that people started to rely on these technologies, these wearable technologies, a little bit more than they should have at the expense of actually paying better attention to their diet, their physical activity,” says Dr. John Jakicic.

Both groups lost weight over the two year study period, but those who didn't rely on the trackers lost about five pounds more.
