This cross-sectional study was carried out to determine the relationship between nutrition according to chronotype and the Mediterranean diet and environmental footprints. "Morningness Eveningness Questionnaire" was used to determine the chronotype classification, and "Mediterranean Diet Adherence Screener" was used to evaluate adherence to the Mediterranean diet. In addition, the food consumption record of the participants was taken and the carbon and water footprints were calculated. A total of 472 adults with a mean age of 22.7 ± 5.0 years participated in the study. Accordingly, 61.0% of the participants were morning type, 15.7% were intermediate type, and 23.3% were evening type. Individuals with higher chronotype values (morning) tended to be more adherent to the Mediterranean diet and had lower environmental (carbon and water) footprints (p < 0.05). The results of this study; showed that diet according to chronotype affects adherence to the Mediterranean diet and environmental footprints.
