Gastric ultrasound will be performed by the radiologist on each participant before the study and at 0, 10, 20, 30, 60, 90, 120 minutes after drinking in the position of head upright 45 degree with left lateral decubitus to evaluate the gastric residual volume and time to empty gastric antrum. If time to empty gastric antrum is extended, ultrasound will be serial performed at 150 and 180 minutes.
We will perform the point-of-care test of glucose before the study and at 60, and 120 minutes after drinking.
Hunger will be measured by a numeric rating scale(NRS) before drinking, 60 and 120 minutes after drinking. The Numeric Rating Scale(NRS) is used for the self-report measurement of hunger levels, defined by numbers from 0 to 10, where 0 represents the lowest level of hunger and 10 represents the highest.

Gastric Residual Volume
gastric ultrasound at the gastric antrum by ultrasound
Time frame: before the study and 0, 10, 20, 30, 60, 90, 120 minutes after drinking the prepared drink each arm.If time to empty gastric antrum is extended, ultrasound will be serial performed at 150 and 180 minutes.
Time to empty gastric antrum
Duration after drinking the drink until the gastric antrum cross-sectional area \< 1.5 ml/kg measure by ultrasound
Time frame: 0, 10, 20, 30, 60, 90, 120 minutes after drinking the prepared drink each arm. If participants doesn't be empty stomach, time will extended to 120 and 180 minutes.
Point-of-care testing(POCT) glucose
measured by point-of-care testing(POCT) glucose at every 60 minutes entire the study
Time frame: Point-of-care testing(POCT) glucose is measured before the study, 60 and 120 after drinking the prepared drink each arm.
Hunger Numeric Rating Scale(NRS)
Hunger will be measured by a numeric rating scale(NRS) before drinking, 60, and 120 minutes after drinking. The Numeric Rating Scale(NRS) is used for the self-report measurement of hunger levels, defined by numbers from 0 to 10, where 0 represents the lowest level of hunger and 10 represents the highest.
