But, fasting glucose can vary quite a bit day to day. So, anyone who's checking their glucose with a glucometer or wearing a CGM, and we'll see that maybe one day their morning fasting glucose is 110, the next day it's 90, the next day it's 80, sometimes it's 70. This can vary a lot for people if they are not getting regular sleep or if they're eating really late at night one night but have an earlier dinner the night before or they go out to eat and have pizza and beer, their glucose is going to be high the next morning.
