Objectives
Narrative objectives1
It has been reported that skipping breakfast leads to increasing of postprandial glucose levels. Previous studies have shown that extending the fasting time affects blood glucose fluctuations. However, the reports regarding skipping lunch and dinner are limited. Additionally, in recent years, habitual skipping of lunch or dinner, not just breakfast, has been increasing among young people. These facts indicate that the research necessity of postprandial glucose effects in lunch or dinner skipping. In this study, we examine the effects of skipping breakfast, lunch, and dinner on subsequent glycemic excursions in healthy subjects.

Interventions/Control_1
Research period is for 14 days.
Patients wear an intermittently scanned continuous glucose monitoring devices (isCGM) on their upper arm. Mealtimes are: 7:00 (breakfast), 13:00 (lunch), 19:00 (dinner).Meal contents are not fixed in this three meal times, prohibited snacks and sweetened drink outside of meal times. Dietary record is by meal photo and weigh high-carbohydrate foods, including staple foods. Meal skipping intervention is day 3-4 (breakfast), day 7-8 (lunch), day 11-12 (dinner). Time to sleep is 24:00, awake time is 7:00. Alcohol consumption and excessive exercise are prohibited from 2 days from the study.

Results
Skipping lunch on both days significantly increased postprandial glucose levels at the subsequent dinner by 1.6 mmol/L compared to when lunch was consumed and breakfast was skipped (p < 0.001). In contrast, skipping dinner or breakfast did not result in significant changes in postprandial glucose levels at the following meal.

Baseline Characteristics
The subjects were 21.9 years old, with a BMI of 20.5.
Participant flow
Thirteen healthy young adults were enrolled and instructed to consume meals freely at designated times while maintaining detailed food intake records. Participants then followed a controlled protocol in which one of the three meals was skipped for two consecutive days in a specified order, with interstitial glucose continuously monitored.
Adverse events
Nothing in particular
Outcome measures
Glucose levels were acquired as interstitial glucose concentrations every fifteen minutes using the isCGM device. Premeal, postprandial peak and the peak from premeal glucose were analyzed. Incremental areas under the curve for postprandial glucose levels for 3 h (3 h-iAUC) were also calculated using the trapezoidal method. Data from days 2, 6, and 10 served as controls. To adjust for dietary intake, the 3 h-iAUC was divided by energy (kcal) or carbohydrate (g) intake, resulting in the adjusted 3 h-iAUC (Adj-3 h-iAUC).
