The purpose of this study was to determine the relationship between breakfast and undergraduate academic performance. This study was conducted based on previous research that only focused on school students, but little research has been conducted on college students. Fifty-two undergraduate students from the International Islamic University Malaysia responded and completed an online survey. The survey questionnaires were adapted from Staub (2000). Participants were asked to rate their academic performance in a particular area such as alertness, participation, attention, mood, note-taking, and anxiety level before the test. The survey also asked the cumulative grade point average to find the correlation between breakfast and students' academic success. The results revealed that eating breakfast correlated with mood and note-taking in class and that students who ate breakfast were more likely to have a good GPA. SPSS was used to analyze the result. The result suggests that breakfast can be considered a healthy lifestyle and can be a platform to help students maintain their learning strategies.Keywords: breakfast, academic performance, academic achievement, INTRODUCTIONThe Breakfast was considered the important meal to start the day.
