Engaging in a healthy lifestyle could be helpful to decrease lifestyle-related health risks and bring long-term health benefits. This research investigated how implicit theories of body weight influence people’s engagement in healthy lifestyle among young adults in China. The results suggested that implicit theories of body weight significantly influence people’s engagement in heathy eating behaviors and physical activity. Self-control mediated the effect of implicit (incremental) theories of body weight on people’s engagement in healthy eating. Implications of the current research for understanding how to promote engagement in healthy lifestyle and directions for future research are discussed.
