Getting organs tested while on cycle, what to do?

[new2thepin]

I have to go in to get some routine organ testing done, as my family has a history of certain illnesses. My question is, I cannot eat for the whole day prior to the testing, and half the day of it. How detrimental is this going to be to my body. I am going from a ~7500 calories total between the day and a half to 0. This cant be good. I have decided not to work out at all these days to help preserve whatever calories I ingest in liquid form, which is all I can ingest(gatorade, water, black coffee, etc). Any opinions?
