Tokyo, Jan. 15 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000060351) titled 'Observational Study on the Relationship Between Meal Duration Measured in Test Meals and Energy Intake in Daily Life' on Jan. 14.

Study Type: Interventional

Study Design: Basic Design - Single arm Randomization - Non-randomized Blinding - Open -no one is blinded Control - Self control

Primary Sponsor: Institute - Fujita health university

Condition: Condition - healthy individuals Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - To prevent obesity and diabetes, people are often advised to eat slowly. However, the scientific examination of eating slowly has not yet been sufficiently conducted. Furthermore, whether someone eats slowly or quickly has largely depended on self-reporting until now. Therefore, we measured meal duration with various test foods and clarified that meal duration is positively related to the number of chews, number of bites, gender, and age. We have also already confirmed the reproducibility and consistency of the test meals. Though we have demonstrated that meal duration and chewing time measured with test foods serve as indicators reflecting individual eating behaviors, it remains unclear whether these indicators are related to meal duration and total energy intake in daily life. Thus, in this study, we adjusted for gender and aim to clarify whether various parameters measured with test foods (meal duration, number of chews, number of bites, tempo) are related to eating habits such as daily energy intake, dinner meal duration, and number of meals per day. Basic objectives2 - Others

Intervention: Interventions/Control_1 - Participants will be asked to eat the test meal, 300kcal microwave pizza. The meal duration will be measured by analyzing the food remaining on the plate every 15 seconds via video using image analysis software to measure the area, or by visual assessment. A stopwatch will be used to time the meal. The number of chews, number of bites, and eating tempo will also be measured. Starting the morning after the test, participants will be asked to record all three meals in the food recording app for at least 7 days within one month. They will also be asked to record the meal duration on a recording sheet at the same time.
