The effectiveness of online messages to change dietary intake and level of physical activity was assessed. Thirty-six volunteers completed a 26-item pre- and post-intervention online survey and received a total of 36 email messages about MyPyramid, food labels, healthier lifestyles, and physical activity. Participants reported increased fiber intake, decreased fat intake, and increased physical activity. Overweight/obese participants lost an average of 8.0 lbs. during the 12-week period. Online messages can contribute to an increase in healthy food consumption and level of physical activity and is a desirable intervention tool for Extension nutrition and health practitioners.
