Healthism and the experiences of social, healthcare and self-stigma of women with higher weight

This study analyses how the discourse of healthism contributes to the social construction of weight stigma in women with higher-weight. In-depth semi-structured interviews were conducted with nine women who had undergone bariatric surgery and had lived with higher-weight during many years. A thematic analysis from a latent and constructionist perspective showed how the discourse of healthism was behind the experiences of stigma lived by the participants in the social and healthcare field. Even instances of self-stigma were found in our data. This study also illustrates how people influenced by healthism assumed individualism and the importance of body shape, core values of neoliberal consumer societies. In this way, people tended to blame women with higher-weight for their weight and to discriminate against for being far from the socially established ideal body. The findings can be useful to prevent weight stigmatization and to promote more appropriate and respectful strategies for obesity prevention and treatment

Preclinical models of stress and environmental influences on binge eating

Preclinical models cannot explain all of the complex internal and external factors that influence eating behaviors in humans. Still, they represent an essential tool to investigate the underlying neuro- and psychobiology implicated in disorders that are associated with binge eating. Several environmental conditions induce aberrant feeding behavior on calorie-dense food in animal models of binge eating. Various kinds of stress (acute or chronic), the combination of repeated cycles of food restriction and refeeding plus stress, food deprivation, and limited access to palatable food have been used to elicit binge-like eating episodes to model human behaviors. Animal studies have revealed the involvement of different neurotransmitter pathways, especially dopamine, opioids, CRF, serotonin, orexin, and GABAergic systems in binge-like eating. They may aid in the ultimate goal of identifying novel, safe, and effective therapeutic targets
