This study aimed to evaluate how a student's chronotype influences their BMI.<h4>Material and methods</h4>Participants were college students from Oral Roberts University (n=384) with a mean age of 18.94 years, a mean BMI of 24.7kg/m², and a mean morningness-eveningness questionnaire (MEQ) score of 47.65.<h4>Results</h4>BMI values were significantly correlated with both chronotype (r=-.11, β=-.09, p=.03) and age (r=.12, β=.53, p=.02). The rate at which BMI increased with age depended upon the student's chronotype (β=.81-.005 / MEQ, p=.005).
