Do you trust your fitness tracker for loosing weight? Well according to a study, wearable devices that monitor physical activity are not reliable tools for weight loss. According to the study, published in the journal JAMA, all participants were placed on low-calorie diets, prescribed increases in physical activity, and received group counselling sessions on health and nutrition. The study specifically investigated whether regular use of commercially available activity trackers is effective for producing and sustaining weight loss. The study followed 470 individuals between the ages of 18 and 35 with a body mass index between 25 and 39 at the start of the trial. Approximately 77 percent of participants were women and 29 percent were from minority communities.

They participated in weekly health counselling sessions for the initial six months and less frequent counselling for the last 18 months. Weight was assessed at six-month intervals throughout the 24-month trial. At the conclusion of a 24-month trial, researchers observed that participants without physical activity trackers showed nearly twice the weight loss benefits at the end of the 24 months.

The researchers conducted a systematic review of 22 published articles researching the ability of Fitbit and Jawbone two popular activity trackers to measure steps, distance, physical activity, calories and sleep. Several studies indicated that the step counting feature was accurate both in the lab and in the field. Only one study assessed distance tracking for the Fitbit, finding that the device tends to over-estimate at slower speeds and under-estimate at faster speeds.
