Vermont [US]: The most popular TikTok content related to food, nutrition, and weight perpetuates a harmful diet culture among teens and young adults, according to new research from the University of Vermont, and expert voices are largely absent from the conversation.
The study, which was just published in PLOS One, found that TikTok is largely dominated by weight-normative messaging or the notion that a person's weight is the most significant indicator of their health. The most popular videos on TikTok glorify weight loss and present food as a means of achieving health and thinness. The findings are particularly alarming in light of prior research showing a link between social media use and disordered eating and negative body image in adolescents and young adults.
"Each day, millions of teens and young adults are being fed content on TikTok that paints a very unrealistic and inaccurate picture of food, nutrition and health," said senior researcher Lizzy Pope, associate professor and director of the Didactic Program in Dietetics at UVM. "Getting stuck in weight loss TikTok can be a really tough environment, especially for the main users of the platform, which are young people."
The study is the first to look at TikTok content on a scale related to nutrition and body image. The conclusions are based on a thorough analysis of the top 100 videos from 10 trending hashtags for nutrition, food, and weight, which were then coded for major themes. When the study started in 2020, each of the 10 hashtags had more than a billion views; the hashtags chosen have increased significantly as TikTok's user base has grown.
"We were continuously surprised by how prevalent the topic of weight was on TikTok. The fact that billions of people were viewing content about weight on the internet says a lot about the role diet culture plays in our society," said co-author Marisa Minadeo '21, who conducted the research as part of her undergraduate thesis at UVM.
