Title: Make Better Choices (MBC) - Multiple Behavior Change in Diet and Activity
Brief Summary: The average adult has a poor quality diet and sedentary lifestyle, but the best way to produce sustained healthy change remains unknown. The MBC2 intervention uses handheld technology to help individuals monitor and transmit information about their eating and activity remotely to a behavior coach. The proposed trial tests whether MBC2 intervention improves diet and activity more than a stress management control condition, and whether changing multiple health behaviors is best achieved by changing them all at the same time, or one after another.
