Exercise monitor increases weight loss

PEOPLE IN A WEIGHT-LOSS PROGRAM got better results if they wore a beeper-sized monitor that showed how much exercise they were getting. Those who wore an activity monitor that immediately told them how they were doing lost an average of 24.2 pounds compared to 14.4 pounds for those without a monitor.
The effect appeared when the participants were trying to maintain their weight loss.
The study which lasted eight months focused on 35 people in their mid-40s.
Everybody was told to walk more and increase their activity in everyday life.
The monitor continuously showed how much time a participant had spent walking at 1.5 mph or more each day.
At the end of the study, those with the monitor averaged about 40 minutes of walking per day compared to only 30 minutes for those without.
On average, people who got immediate feedback also continued to lose weight through the 8 months of the study, while those without a monitor gained weight between the 7th and 8th month.
The results were presented by psychiatrist Dr. Daniel Safer of Johns Hopkins University at a 1998 meeting of the American Psychiatric Association.
