Childhood obesity is a significant public health challenge. Research says that a key period for targetting dietary intervention is adolescence, when young people become more independent, making their own decisions about diet, and socialising with friends more. Adolescents eat out a lot. Everyone generally tends to consume higher-calorie meals when eating out. Previous interventions have targetted healthy eating at home and in school, but researchers from the University of Birmingham theorised that restaurants would be an important location for implementing low-cost and high-reach interventions to encourage healthier eating in teenagers. Their study, published in the journal ‘Appetite’, shows that putting lower-calorie meal choices at the top of a restaurant menu, and reducing the availability of high-calorie options, makes teenagers more likely to order the healthier options and might be a useful tool in trying to reduce obesity and help young people make healthier choices.
