Abstract Evidence for a relationship between Internet use and body image and eating concerns has started to emerge, however, to date, this literature has not been reviewed. The objective of the present study was, therefore, to review the literature examining the relationship between the use of Internet and social media and body image and eating concerns, and summarize the main findings. Data-bases were searched for published empirical studies examining the relationship between body image and eating concerns and Internet use. Our search identified 67 studies. The findings indicate the presence of appearance-related content on Internet and social media, including content promoting extreme body shapes or behaviors. The results from qualitative, correlational and experimental studies overall support the relationship between Internet use and body image and eating concerns. The studies identified were grounded in three main theoretical frameworks: sociocultural, objectification theory, and social identity
theory; however, other more minor frameworks were also used. The use of Internet, and particularly appearance-fo-cused social media, is associated with heightened body image and eating concerns. Developmental characteristics may make adolescents particularly vulnerable to these effects. Keywords Internet Social media Body image Eating disorders Adolescents
