1 Fitness trackers are popular accessories for 2 people who want to follow their steps and sleep. 3 but so far research suggests that they are not 4 especially good at helping people lose weight. In 5 a 2016 study, researchers followed 470 people 6 who were trying to lose weight for two years. 7 People were split into groups and asked to either 8 follow a low-calorie diet, increase their physical 9 activity and attend group counseling, or to follow 10 the same regimen but add wearable technology 11 six months in

12 People using wearables lost 7.7 pounds on 13 average, but the people who weren't using them 14 lost an average of 13 pounds. As wearables 15 continue to advance they may become more 16 useful for weight loss, but if you're on the fence 17 about buying one, you can probably save your 18 money.
