Some interesting findings have raised questions about whether trendy wearable activity monitors make a difference in terms of weight loss. The AMA Morning Rounds from September 21st sum up what was found.

According to research:
The New York Times (9/20, Reynolds, Subscription Publication) reports that research published in JAMA suggests “wearable activity monitors” may not help people lose weight.

STAT (9/20, Love) reports that investigators “recruited 470 overweight or obese adults for an exercise and dieting program.” During “the first six months, they had group sessions on calorie restriction and physical activity.” The researchers “then…reduced face-to-face meetings (replacing them with phone counseling and self-reporting via the web) and gave about half the group…wearable devices.”

TIME (9/20, Sifferlin) reports that the participants “using wearables still lost some weight, but significantly less than the people who weren’t using them.” Participants “in the standard weight loss group lost 13 pounds on average, whereas the people in the wearables group lost 7.7 pounds on average.”

The CBS News (9/20, Marcus) website points out that “an editorial published last year in the Journal of the American Medical Association suggested that more than half of the people who buy fitness trackers eventually stop using them – about one-third giving up on their devices after about six months.”
