Overlooked benefit of successful healthy lifestyle programs: Improved quality-of-life -- ScienceDaily

Before beginning the program, each participant ranked his or her current health on a scale from 0 "worst imaginable health state" to 100 "best imaginable health state." The U.S. average is 79.2, whereas the participants averaged 71.5 at baseline. After completing the year-long Group Lifestyle Balance program, the participants increased their average health-related quality-of-life score to 78.2. When looking at only those with baseline health-related quality of life below the U.S. average, there was an even greater magnitude of improvement, from 61.8 at baseline to 74 at the end of the program. Once scores were adjusted for meeting weight loss and physical activity goals, participants who met the program goals were found to have increased their health-related quality-of-life score by nine more points compared to those participants who met neither program goal.
