This report examines the growing concern of obesity among young adults in Hong Kong and explores strategies for prevention through community and public health nutrition. It highlights the increasing prevalence of obesity, its associated health risks, and the influence of obesogenic environments. The Analysis Grid for Environments Linked to Obesity (ANGELO) framework is proposed for analyzing contributory factors. A key focus is on the efficacy of educational sessions in promoting healthier behaviors among individuals aged 18-25, with specific objectives and strategies outlined to improve dietary habits and reduce unhealthy food intake. The report also touches upon poor nutrition as a global public health issue, particularly in Australia, emphasizing the need for early intervention and addressing data gaps in understanding the effectiveness of educational programs. The evaluation framework suggests regular data collection through questionnaires to assess changes in motivation and behavior.
