Objective <p>This study aims to investigate the effects of chronotype on resting metabolic rate (RMR) and anthropometric measurements among female university students.</p> Methods <p>The study was conducted with 92 female university students aged 19–25 years, comprising 46 morning-types and 46 evening-types who met the study criteria. Participants’ 3-day dietary intake, body composition (by Tanita MC 780), and waist circumference measurements (using a non-stretchable tape) were collected, and RMR values were determined using the BodyGem device. To determine the chronotype Morningness Eveningness Questionnaire (MEQ) was applied.</p> Results <p>The participants’ average age was 22.20 ± 1.50 years. No significant difference was found between RMR, sleep duration, and chronotypes (<i>p</i> &gt; 0.05). However, morning-type individuals had lower BMI, body fat percentage, and waist circumference values compared to evening-types (<i>p</i> &lt; 0.05).</p> Conclusion <p>These findings suggest that chronotype is associated with differences in body composition rather than resting metabolic rate or sleep duration. Evening-type individuals exhibited higher adiposity-related measures, indicating that circadian and behavioral factors may play a key role in metabolic health.</p>
