Weight-loss diets among female Korean adolescents: a pilot study based on a social media platform
2022
Overview
PurposeThe study aimed to analyse the nutritional quality of self-proposed or prescribed weight-loss diets shared by female Korean adolescents through a social media platform and identified potential dietary problems.Design/methodology/approachA total of 317 weight-loss diets, shared by 107 female adolescents between the ages of 12 and 18 in April 2019, were collected from three Kakao Open Chat rooms of which the main topic was “weight-loss diet”. The weight-loss diets were converted to daily energy and nutrient intake.FindingsApproximately two-thirds of the subjects were normal or underweight, and more than half of them were limiting energy intake to less than half of the recommended daily amounts. The average daily intake of energy and most nutrients did not meet the standard intake levels. Approximately 20% of the subjects were breakfast skippers, while 8 and 5% were dinner and lunch skippers, respectively. Notably, meal skippers tended to fast longer and have an uneven distribution of daily energy intake per meal. The percentages of energy contribution from macronutrients, particularly carbohydrates, also deviated more from the acceptable range in the meal skippers. The weight-loss diets of the subjects with particularly low daily energy intake were categorised into simplified, unbalanced and nutrient-poor, energy-dense meals. Overall, the nutritional quality of the self-proposed or prescribed weight-loss diets was poor. More effective and proactive educational interventions in school environments should be developed to promote positive eating behaviours in adolescents and free them from their obsession with body image.Originality/valueTo the best of the authors’ knowledge, this study is the first attempt to analyse the nutritional quality of female adolescents' self-proposed or prescribed weight-loss diets.
