The study design included two different groups. We recruited thirteen students and asked for their
breakfast frequency. Subjects who ate breakfast every day will be called the “breakfast group”, and subjects
who ate breakfast only two times or less during the week will be called the“skipping group”. Each of the
subject's characteristics was shown in Table 1. Their age and anthropometric measures were presented in
Table 1. Both groups had movement customs. None of the participants had a disease or received drugs. All
subjects were recruited by a notice board within the university and gave a signature of informed consent
before inclusion
