PowerFood: Turns Fruit Eating into Fun and Makes Snacks Not Done

摘要

This paper provides an outline of the persuasive mobile application 'Krachtvoer' (In English: PowerFood) that encourages adolescents with moderate overweight to eat more fruit and fewer snacks. The key features of this solution are dynamic goal setting, personal reminders, progress monitoring, social interaction and competition with friends. Results of the evaluation indicate that the app enhances the user's attitude and self-efficacy towards eating fruit and healthy food. In addition, social influences encourage users to eat more fruit and less unhealthy snacks.
