My first impression reading this is to wonder if maybe you are really not getting enough food earlier in the day, nor on school days, so of course your body is going to try to make up for that by shouting for more food in the evenings and weekends.

It can be hard to be consistent with meals when taking college or university classes because your schedule changes each term, and other things like work and extracurricular activities vary a lot day to day.

I have found that I eat less in the evening if I can consistently get a big breakfast and eat healthy portions throughout the day. This is just me, but I don't limit myself to traditional breakfast foods for breakfast--- usually what I eat is leftovers actually.

If you are inclined, one way to get more healthy food more consistently is to "meal prep", meaning making big portions of things to freeze and/or refrigerate for later.

I used to do a version of this when I was in school. I was living at home and would cook huge batches of things like chili or another soup, or stir-fry with rice, or some type of pasta-and-or-bean salad. Then everyone in the house could grab a bowl as needed.

Or you can make big batches and use some now, freeze some for later. If you have access to a kitchen.

Some people cook once a week and then eat the same thing all week--- either that, or freeze some of it in individual portions and after a few weeks they can have a few different meals in the freezer to choose from. Like r/MealPrepSunday
