Abstract

Eating Style of 166 healthy male volunteers (42.7±9.3 yers old) was observed indirectly by Video tape recording (VTR observation) in the search for the characteristic Japanese eating style "HAYAGUI" (eating more rapidly). The meal with same content (757 kcal, 580 g in weight) has taken unrestrainedly in all subjects without changing eating place. Subjects characteristics, meal duration, amount of food, mouthfuls, chews, pause duration, and rates of food consumption per 30 seconds were observed by played back tapes. Six types were classfied in changes in the rate of food consumption, and the six types combined into three eating styles, regardless of similar meal duration. The analysis of variance for hunger, thirst, fullness and other subjective factors rating immediately before and after the meal have shown no signif icances among 3 styles. The most impressive eating style was "Zenhan-type" (25.9% of all subjects), which was characterized by higher rate of food consumption (above 10% of which food per 30 seconds) during the first half and more chewing than other types.
