Fitness Trackers no Guarantee for Weight Loss

A new study suggests wearing a fitness tracker to tally the number of steps you take in a day doesn’t necessarily mean the numbers on the scale will come down. The University of Pittsburgh recruited more than 400 overweight and obese young adults. They all went on a low-calorie diet, exercised and had counseling and support. Half were given activity monitors, worn on the upper arm, that measured energy expenditure. The theory was the devices would lead to greater weight loss. The strategy didn’t work.
