• Previous research has demonstrated that growing up poor and having a cognitive schema or mindset for the world/people as unpredictable is predictive of eating in the absence of hunger (EAH; Hill et al., 2016; Proffitt Leyva & Hill). The purpose of the current study was to examine how ghrelin, "the hunger hormone", is related to childhood factors such as low SES, environmental unpredictability, and EAH. Results revealed a significant relationship between the unpredictability schema and ghrelin slopes across time for individuals with high versus low unpredictability schemas. Specifically, individuals with a more robust unpredictability schema had a flatter ghrelin response to a tailored caloric load compared to individuals with a less robust unpredictability schema. Low childhood SES and environmental unpredictability were not significant predictors of an unpredictability schema, and there were no differences in calories consumed between those with a higher versus lower unpredictability schema. The results of this study indicate that mindset is important for energy regulation
