Although "you are what you eat" is a well-worn cliché, personal identity does not figure prominently in many debates about the ethics of eating interventions. This paper contributes to a growing philosophical literature theorizing the connection between eating and identity and exploring its implications for eating interventions. I explore how "identity-policing," a key mechanism for the social constitution and maintenance of identity, applies to eating and trace its ethical implications for eating interventions. I argue that identity policing can be harmful and that eating interventions can subject people to these harms by invoking identity policing qua intervention strategy or by encouraging people to eat in ways that subject them to policing from others. While these harms may be outweighed by the benefits of the intervention being promoted, they should nonetheless be acknowledged and accounted for. To aid in these evaluations, I consider factors that modulate the presence and severity of identity-policing and discuss strategies for developing less harmful eating interventions. I conclude by considering the relationship between identity-policing and identity loss caused by long-term diet change. This paper contributes to the centering of identity in food ethics and to a more comprehensive picture of identity's ethical importance for eating interventions.
