ABSTRACT
There is accumulating evidence that disgust plays an important role in prejudice toward individuals with obesity, but that research is primarily based on self-reported emotions. In four studies, we examined whether participants displayed a physiological marker of disgust (i.e. levator labii activity recorded using facial electromyography) in response to images of obese individuals, and whether these responses corresponded with their self-reported disgust to those images. All four studies showed the predicted self-reported disgust response toward images of obese individuals. Study 1 further showed that participants exhibited more levator activity to images of obese individuals than to neutral images. However, Studies 2-4 failed to provide any evidence that the targets' body size affected levator responses. These findings suggest that disgust may operate at multiple levels, and that the disgust response to images of obese individuals may be more of a cognitive-conceptual one than a physiological one.

Obesity is a major public health concern worldwide. Because individual-level interventions have been unsuccessful at curbing obesity rates, there is an emphasis on public health approaches. In addition to testing the effectiveness of any public health interventions, it is important to consider the ethical implications of these interventions in order to protect the public's rights and promote overall well-being. In this paper, we review public health approaches to obesity in three broad domains (changes to the socio-communicative environment, changes to the economic environment, and changes to the physical environment/access) and consider the potential ethical issues that arise in each of those domains. We suggest that interventions that target the physical environment/access (making it easier for people to engage in healthy behaviors), that target the entire population (rather than just individuals with obesity), and that focus on health behaviors (rather than on weight) have the least potential for ethical concerns.
