Feeling way hungrier at night

Long time lurker, first time poster. Sorry if this has been asked before, I couldn't find it.

Does anyone else feel waaaaay hungrier at night than during the day? My sleep routine is usually 3 am to 11pm, and I'm lucky to have a job that can accomodate that. But, during lunch, usually between 12pm and 1pm I feel next to no hunger, I pick at my food and usually can't finish a single plate. Then, during the day, I eat a little, but when night comes I feel a huge hunger spike, and want to eat everything in the house throughout the entire night. Does anyone else feel the same? My theory is that it's related to a delayed methabolism, but I'd like to hear some other opinions.

Yup.

I think this is related to the hormone orexin. It’s the hormone that wakes you up, as well as doing other things we associate with wakefulness. Causes urine to be produced by the kidneys and regulates appetite.

My experience has been that non-hungry time is the sleep phase for that hormone. If I can sleep during the period when I’m not hungry I do so much better. If I eat during the period when I’m not hungry I’m giving myself three days of irritable bowel symptoms.

It stinks. But here we are.
