Breakfast is widely recognized as a crucial dietary source of energy, particularly for students whose academic performance and daily functioning are highly influenced by morning nutrition. Regular breakfast consumption is associated with improved attendance, body weight maintenance, mental alertness, energy levels, and overall enthusiasm and motivation throughout the day. In contrast, skipping breakfast is increasingly prevalent among young adults, with reported rates of 18–25% among university students and up to 36% among adolescents. This habit is linked to adverse outcomes, including decreased academic performance, poor class attendance, impaired attention and cognition, mood disturbances, and lower overall energy levels. Skipping breakfast often leads to compensatory intake of high-fat, low-vitamin foods later in the day, increasing the risk of gastrointestinal issues and higher Body Mass Index (BMI). Moreover, the absence of morning carbohydrates can result in hypoglycemia, reducing both physical and cognitive performance. This study investigates the relationship between breakfast skipping and student performance at Eastern University, Sri Lanka, highlighting the negative impacts on health and learning outcomes. Findings from this research can inform interventions and policies promoting regular breakfast consumption among university students, ultimately supporting their academic success and well-being.
