  • The research was carried out by the University of Birmingham’s Katie Edwards and Aston University’s Jackie Blissett and James Reynolds
  • Both the availability of high-calorie options and their position on the menu affects teenagers’ choices
  • Restaurants provide an important location for implementing low-cost and high-reach interventions to tackle obesity.


New research from the University of Birmingham and Aston University has found 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.


Childhood obesity rates have been increasing year on year, with government pledges and targets to reduce obesity unfulfilled or missed. Restaurants are a common food environment for adolescents, with one fifth of children consuming meals out at least once a week. The study has been published in the journal Appetite.


Dr Katie Edwards, research fellow in psychology at the University of Birmingham and a visiting researcher at Aston University, who led the study, said:


“Childhood obesity is a significant public health challenge. A key period for targeting dietary intervention is adolescence, when young people become more independent, making their own decisions about diet and socialising with friends more. Interventions have targeted healthy eating at home and at school, but we wanted to see how altering restaurant menus can impact the choices teenagers make.”


The researchers asked 432 13 to 17-year-olds to take part in an online experiment. They presented the teenagers with three different menus, with five starters, ten main courses and five desserts in separate sections, as one would find on a standard restaurant menu. Each menu was slightly different; one which reduced the number of high-calorie options on offer, one with menu positioning of low- to high-calorie meals, one which combined the availability and position interventions, and then one ‘typical’ menu. The participants were asked to select a starter, main and dessert from each menu.


The experiment showed that the availability and the position interventions resulted in significantly lower calorie meal choices, compared to the choices made from the menu with no intervention (the ‘typical’ menu). The average number of calories for a selected meal reduced from 2099.78 to 1992.13 when the items were ordered from least to highest calorie content. The availability intervention reduced it from 2134.26 kcal to 1956.18 kcal. The group who had the combined availability and positioning intervention menu saw their meals’ calorie value plummet from 2173.60 kcal to 1884.44 kcal.


The study also found that the positioning intervention had the biggest impact on main course choices. The availability intervention and the combined interventions, on the other hand, did not have a big impact on the calorie value of main course choices. The availability intervention had the most impact on starter choices. None of the interventions had a significant impact on dessert choices.


Dr Edwards said:


“Main menu choices saw the biggest reduction in calories following the position intervention, going from 1104.17 kcal to 1045.16 kcal, while the availability intervention saw the biggest reduction in the starter option. While not all interventions saw statistically significant reductions for all courses, each intervention saw a significant reduction in the calorie content of the overall meals.”


Dr James Reynolds, senior lecturer in psychology at Aston University, said:


“People tend to consume higher calorie meals when they eat out, so restaurants provide an important location for implementing low-cost and high-reach interventions which can encourage healthier eating in teenagers. Many restaurants are already required to display calorie information on their menus, but our research has shown that tactics like altering the position or availability of high-calorie options on menus could also be a useful tool in trying to reduce obesity and help young people make healthier choices. The next step for this research would be to replicate the study in restaurant settings.”

Play, Learn, Lead: How Aston’s Gamification-Driven MBA Is Redefining Business Learning

Professor Helen Higson OBE of Aston Business School, discusses why gamification is embedded in all of the School's postgraduate portfolio of degrees Give the students something to do, not something to learn; and the doing is of such a nature as to demand thinking; learning naturally results. (attributed to John Dewey, US educational psychologist (1859-1952) Imagine you’re the CEO of a cutting-edge robotics firm in 2031, making high-stakes decisions on R&D, marketing and finance; one misstep and your virtual company could collapse. You win, lose, adapt, and grow. This isn’t a case study, it’s your classroom experience at Aston Business School in Birmingham. Imagine you’re participating in Europe’s biggest MBA tournament, the University Business Challenge, where your strategic flair and financial acumen will be tested against the continent’s sharpest minds. Then you’re solving real-world sustainability crises in the Accounting for Sustainability Case Competition, crafting solutions that could be showcased in Canada. What if you could do all this from your classroom seat, armed with only your MBA learnings, teamwork and the thrill of gamified learning. At Aston, we believe the best way to master business is by doing business. That’s why we’ve embedded active learning through games, simulations, and competitions across all our postgraduate programs. The results? Higher engagement, deeper learning, and students who graduate with confidence and real-world skills. Research says gamified learning boosts motivation, lowers stress, and helps students adopt new habits for lifelong success. As educational researchers Kirillov et al. (2016) found, “Gamification creates the right conditions for student motivation, reduces stress, and promotes the adoption of learning material—shaping new habits and behaviours.” This has led to what Wiggins (2016), calls the “repackaging of traditional instructional strategies”. In Aston Business Sschool we have long embraced this approach as a way of increasing student outcomes and stimulating more student engagement in their learning. Our Centre for Gamification in Education (A-GamE), launched in 2018, is dedicated to advancing innovative teaching methods. We run regular seminars with internal and external speakers showcasing gamification adoption, design and research and we use these techniques across the ABS in a wide range of disciplines. (We have included two examples of this work in our list of references.) Furthermore, in 2021 we published a book which outlines the diverse ways in which we use these methods (Elliott et al. 2021). Subsequently, during 2024 we redesigned all our postgraduate portfolio of degrees, and as part of this initiative games and simulations were embedded across all programmes. Why Gamification Works Through simulations like BISSIM, students step into executive roles, steering futuristic companies through the twists and turns of a dynamic marketplace. A flagship programme running since 1981, BISSIM was developed in collaboration between academics from ABS and Warwick Business School, and every decision on R&D, marketing, or HR has real consequences as teams battle each other for the top spot. After each year of trading the results are input into the computer model. The results are then generated for each company in the form of financial reports, KPIs and other non-financial results and messages. Each team’s results are affected by their own decisions and the competitive actions of the other teams, as well as the market that they all influence. This year one of our academics, Matt Davies, has been awarded an Innovation Fellowship further to commercialise the game. Competitions with Global Impact We also encourage students to take part in national and international competitions which have the same effect of developing their engagement with real-life business problems on a global scale. Beyond the classroom, Aston students represent the university in major competitions like the University Business Challenge (in which ABS had the highest number of UK teams this year) and the Accounting for Sustainability (A4S) Case Competition, for which we are an “anchor business school”. Here, theory gets stress-tested against real-world scenarios and top talent from around the globe. The result? Award-winning teams, global experience, and friendships built under pressure. At the heart of this approach is Aston’s Centre for Gamification (A-GamE), dedicated to making learning interactive, motivating, and fun. Regular seminars, fresh research, and close ties to industry keep the curriculum evolving and relevant, so students graduate ready to lead, adapt, and thrive in any business environment. Why does it matter? In a volatile, fast-paced economy, employers appreciate agility, teamwork and decisiveness. At Aston, every simulation and competition is geared towards sharpening these skills. Graduates emerge not only knowledgeable, but prepared for the job market. Engagement Our students have been embracing these opportunities. Six MBA/Msc teams developed their A4S videos, hoping to reach the final in Canada early in 2025, and three teams out of nine reached the national UBC finals. Additionally, the BISSEM simulation has just finished inspiring another group of MBA students (particularly as the prize for the winning team was tickets to a game at our local Aston Villa premiership football (soccer) club, currently riding high in the league!). Typical feedback from non-Finance specialists is that they suddenly surprised themselves during their participation in the simulation and were reconsidering the options of taking a career in Finance. It seems that our original purposes have been met – increased confidence, passion, deep learning and engagement have been achieved.

Are GCSEs delivering for students and society?

Ahead of the GCSEs results being released on Thursday 21 August Aston University work psychologist, Dr Paul Jones, discusses whether the exams are fit for purpose. He believes that our exam system narrows thinking, and GCSEs emphasise “right answers” and rote recall, creating risk-averse learners who are afraid to fail or think differently. Exams are harming wellbeing GCSEs were designed in the 1980s, when many left education at 16. Today, almost all young people continue to 18, yet they still face a stressful halfway checkpoint that often does more harm than good. Research shows GCSEs are linked to anxiety, sleeplessness and even self-harm. This isn’t about students being “less resilient”, t’s about a system that has prioritised bureaucracy, league tables, and exam statistics over wellbeing. GCSEs don’t prepare students for life Exams reward the ability to memorise and recall under pressure, but the world beyond school demands much more. Employers and universities want young people who can think critically, manage their own learning, collaborate, and adapt. By the time many reach university, students are burnt out from years of high-stakes testing. They often struggle with independence, risk-taking, and curiosity, the very qualities they need to succeed. Over-assessment stifles innovation Our exam system narrows thinking. GCSEs emphasise “right answers” and rote recall, creating risk-averse learners who are afraid to fail or think differently. Innovation, however, requires psychological safety: the freedom to explore, experiment, and make mistakes. In a world where AI can already handle routine tasks like recall and pattern analysis, the human edge lies in breaking moulds, challenging assumptions, and combining knowledge in new ways. Our current system suppresses exactly those skills. Moving GCSEs into the future We need fewer, smarter assessments and a curriculum that builds creativity, resilience, and innovation. Other countries use project-based learning, portfolios, and sampling tests to capture what young people can really do. Wales is already embedding wellbeing and digital skills into its new curriculum. England risks being left behind if it continues to cling to an exam-heavy model designed for a different era. The bottom line Our young people deserve an education that prepares them for life, not just for exams. We should be measuring what really matters: wellbeing, creativity, and the ability to thrive in a fast-changing, AI-driven world.
