I have a messed up sleep schedule, will this affect my diet?

Right now I got a messed up sleep schedule again, and that makes me stay up all night, and sleep for most of the day, usually skipping through breakfast and lunch time. When I get up I eat cereal, then at 5:30pm I would usually exercise, most of the time it is for 20 minutes, I switch to running then weight lifting the other day. Then dinner around 7 and maybe a snack later. It's summertime and I just want to know if this will affect me badly. I'm eating healthy and exercising at least, a lot of people would want to be in my shoes.
