Introduction: Adolescent obesity is rising in the United Kingdom (UK), and it is more prevalent in older adolescents aged 15-19 years than in almost any other higher income nation. Obese children and adolescents are at a high risk of developing several chronic diseases (NHS Digital, 2021; Nuffield trust, 2021). Providing nutritional information (NI) in the form of a food label (FL) is one strategy that has the potential to reduce obesity. A FL allows consumers to compare the NI between similar food products which can theoretically guide consumers as to which are the healthier food choices. Since December 2016 all prepacked food in the UK was required to display mandatory NI on the back of a FL, presented per 100g/ml or per portion of the product. The NI includes energy in kJ, and kcal and the number of grams of fat, saturated fat, carbohydrates, protein, and salt. NI on the front of prepacked FL is voluntary and is predominantly assessed through a nutrient profiling model (NPM) which can be a nutrient specific or a summary system. The process of NP includes several stages dependent upon its purpose. To date, there are a plethora of different front of pack FL designs yet no consensus as to which design has the greatest influence on food choice behaviour (FCB). School food can theoretically provide a third of an adolescent daily calorie intake, yet schools in England have no policies to inform pupils as to which food options are the healthiest. The UK government has announced that from April 2022 it will enforce all businesses with 250 or more employees in England including cafes, restaurants and take away food to display calorific information on non-prepacked food and soft drinks (GOV.UK, 2021) but this does not include school food. There are three known published studies (Hunsberger et al., 2015; Rainville et al., 2010; Conklin and Cranage, 2005), and one unpublished study (Fresques', 2013) that have provided NI in the form of calories and fat in a live school setting in America. Results did not concur as to the ...
