OBJECTIVE: It is important to know normal GEHT of a specific meal taken at specific hours and at specific physical and biological conditions in order to better evaluate abnormal GEHT. It seems that it is more specific to study as we have done in the present paper GEHT in the same individual of a certain meal administered at two different hours, i.e. in the morning and at night. Thus, we avoided many errors and issues.SUBJECTS AND METHODS: We studied 2 healthy individuals, one male 26 years old and one female, 19 years old, who received the same French toast meal at 08.00 and 23.00.RESULTS: The GEHT for the morning and the night test for the male individual (P.F.) were 55min and 125min, respectively. For the female individual (K. F.) the GEHT were ∼70min and ∼120min, respectively. For both individuals GEHT differed more than 220% between the morning and night tests.CONCLUSION: We noticed a more than 220% delay of the GEHT in a normal young man and a normal young woman when they received a French toast meal at 23.00h as compared to the same meal at 08.00h. The female had 58% more delayed in GEHT at night as compared to the GEHT of the male individual.
