“…However, the distribution of nutrients in the three meals may differ between chronotypes, even if the difference in the TEI is small. An ET was more likely than an MT to skip breakfast or consume fewer calories during breakfast while consuming more calories during dinner and snacks in the afternoon or at night [ 30 – 32 ]. Additionally, irregular meal patterns were also found to be associated with chronotype among Japanese university students [ 33 ].…”

“…However, no significant differences were observed between the groups in FI and CI, suggesting that these intakes may have been relatively higher in ETs. In previous studies, the intake of lipids, carbohydrates, sodium, and polyunsaturated fatty acids [ 32 ] or sucrose and saturated fatty acids [ 37 ] was higher in ETs than in MTs, and a later chronotype was associated with a lower overall dietary quality index [ 38 ]. Furthermore, this difference was more pronounced on weekends [ 37 ].…”

Background Having higher muscle mass in early adulthood is an important factor in preventing sarcopenia. However, university students undergo lifestyle changes compared to their high school years, which may lead to changes in body composition, such as an increase in body fat and a decrease in muscle mass. The study aimed to investigate the association between body composition and lifestyle behaviors, including chronotype, among Japanese female university students, due to the prevalence of underweight among young females in the country. Methods The physical activity level (PAL), daily dietary intake status, morningness-eveningness questionnaire (MEQ) score, and body composition of 230 students were assessed in this cross-sectional study. Body composition was measured using a multifrequency bioelectrical impedance analyzer, and body mass index (BMI), body fat percentage (%BF), and skeletal muscle mass index (SMI) were determined. Results Individuals who were evening type (ET) had a higher %BF and lower SMI than those who were non-ET, but no differences in body weight or BMI were found. Although ET individuals had lower total energy intake, protein intake, and PALs than non-ETs, the differences were small. However, multiple regression analyses showed that SMI was significantly positively associated with MEQ and PAL, and %BF was significantly negatively associated with MEQ and PAL. Conclusion These results suggest that female university students with lateness of chronotype and low physical activity have a body composition imbalance resulting in higher body fat and lower muscle mass. Therefore, young females may need to take chronotype-specific measures (especially ET individuals) to help them maintain an appropriate body composition.
