Although the persuasion-based health behavior change systems have achieved certain success particularly in motivating physical activity, researchers now start criticizing that persuasion-based systems have problems in taking over too much control, paying not enough attention to people's thinking, and failing in acknowledging  external  constraints and exploring resources. The alternative notion of reflection has been supported by different researchers' views, and in my thesis work I aim to explore this notion in the context of dietary change. The main goal of my thesis work is to explore what people think in the different food- related activities and apply those understandings into system designs to foster and assist people's reflection on everyday dietary change.
