This FIT device concept, also a finalist in the competition, helps users adhere to a fitness plan with calorie-burn and heart-rate monitors, progress reports, and more. If the fitness plan is not followed, the device adjusts the user's diet to keep him or her from consuming too many calories. The more calories burned, the more calories he or she is allowed to consume.
