Gee..this sounded so good

You know those cellphone apps that track exercise, calories, and weight loss goals...Well, researchers at Duke University found they don't help young adults achieve meaningful weight loss.

Sad face.

Thirty-five percent of 18 to 25-yr-olds are overweight or more, according to Laura P. Svetky, MD, professor of medicine at Duke.

They thought this tech savvy group would be likely to benefit from a high tech electronic aid.

The researchers looked at 365 people in this age group, all of whom had weight issues. One group used a free Android app called CITY (Cell Phone Intervention for You), designed for this study by people at Duke and Northeastern University.

CITY tracks calorie intake, activity, and goals, and offers tips and ways to get social support.

On average, the CITY users lost 2 pounds after two years. This was no more than the control group--which received paper handouts about exercise and nutrition.

They also studied personal coaching--the coaches met with participants weekly for six weeks then phoned once a month. The coached group lost about 8 pounds in a year, the control group in that study, 5 pounds.

After two years, neither group was using a cellphone app or coach.

They also tested commercial weight loss apps rather than CITY. No difference.

Maybe the app wasn't interactive enough, they said. Back to the drawing boards.
