Obesity is a visible public health problem that remains a neglected issue. The media can promote healthy lifestyles, however, it can become a means of disinformation. The study's objective was to perform a bibliometric analysis on the coverage of obesity in the media and social networks through the search for scientific information in the Web of Science, where 1191 open-access articles were obtained, which were analyzed in the VosViewer software. It was observed that there has been an increase in scientific publications regarding obesity in recent years. The importance of physical activity, prevention, and influence of social networks is highlighted. However, there are gaps in research, especially in media and social media communication to prevent obesity. A multidisciplinary approach is required, involving the media, governments, and health professionals.
