1. Eating after you fast.
2. First meal of the day.
Once you have your regular 7 to 8 hour sleep,( mainly durning the night), your body basically fast because you haven't eaten in hours. So to fuel your mind and body, you break your fast by eating a meal when you wake up, (mainly in the morning).
The doctor told me to fast by not eating after 9pm for blood work in the morning.
