Obesity has become a serious problem worldwide in the modern society with the change of food culture. Obesity would be a cause of many diseases such as hypertension, dyslipidemia and diabetes. Considering obesity, we examined satiety closely related to energy intake. In this study, we focused on the number of chews and chewing frequency, which are factors of satiety, and analyzed the influence on it. In the experiment, we compared satiety, hunger and masticatory muscle activity among the conditions when participants ate the same amount of food under the condition that the number of chews and the chewing frequency were changed. As a result, the datas of the increase rate of satiety and the masticatory muscle activity showed that participants of low weight and normal weight who consumed foods by chewing many times, and participants of obesity who consumed foods with large masticatory muscle activity for each chew could feel fullness earlier. Using this result, people can reduce the energy intake naturally by feeling fullness early in the diet, and it is expected to improve the eating habits of obese people.
