Why can’t you eat past a certain time at night if you have to take a blood test the next morning?

Question

I am supposed to take a blood test in the morning and my doctor told me that I have to do it on an empty stomach, and can’t eat anything after 9pm. I understand how alcohol, for one, could impact blood test results but why food? Asking cause I’m hungry 🙁
