This paper explores why Canadian government policies, particularly those related to obesity, are 'stuck' at promoting individual lifestyle change. Key concepts within complexity and critical theories are considered a basis for understanding the continued emphasis on lifestyle factors in spite of strong evidence indicating that a change in the environment and conditions of poverty isare needed to tackle obesity. Opportunities to get 'unstuck' from individual-level lifestyle interventions are also suggested by critical concepts found within these two theories, although getting 'unstuck' will also require cross-sectoral collective action. Our discussion focuses on the Canadian context but will undoubtedly be relevant to other countries, where health promoters and others engage in similar struggles for fundamental government policy change.
