The presented study is based on three theoretical approaches: the sociocultural model of eating disorders, self- determination theory and objectification theory. The study has two aims. Firstly, to test a model of body dissatisfaction in women based on these theories and secondly, to experimentally examine the effect of low-intensity fat talk on body dissatisfaction and its related variables. The results showed that body surveillance and self-determination were directly associated with body dissatisfaction. There was an indirect effect of thin-ideal internalization on body dissatisfaction as well as an indirect effect of self-determination on body dissatisfaction, both through body surveillance. The experimental effect of this subtle form of fat talk was not confirmed. However, the content analysis of the participants’ short texts revealed that even this form of fat talk was associated with marked body dissatisfaction and negative emotions for some participants. In summary, body surveillance was a central variable in the model of body dissatisfaction in young women. This habit of constant monitoring of body appearance is not trivial and should be addressed in interventions.

The concept of body image can be considered on many levels, but constant is the fact that it is a mental image: of the size, shape, and form of one’s own body, influencing one’s overall self-image. Previous multifaceted research shows that perceptions of body image can be influenced among other things by physical activity or personality. Therefore, the purpose of this study was to analyze the relationships between body image perception and personality, considering individuals who regularly practice physical activity (N= 104). The following research tools were used: IPIP- BFM-20, Body Esteem Scale and a questionnaire consisting of questions allowing for the respondents’ characterization. Analysis of the collected data revealed that almost half of the respondents are currently dissatisfied with their body image. It was also noted that those who were satisfied with their body image scored statistically significantly higher on two of the five personality traits measured: Extraversion and Emotional Stability. The results obtained showing the relationship between personality and body image perception are consistent with previous studies in which the type of physical activity and its frequency were not examined.
