how to stop feeling hungry?

this is bleak, but times are getting tougher financially- im a full time student and work two jobs, but was just laid off of one and the other one is up in the air with trumps grant freeze. i noticed that my biggest expense is food and i’m not super skinny but i’m also not fat (5’4, 145lbs), so i was thinking i can probably get away with eating less to get by. does anyone have any advice for suppressing hunger lol thanks
