None of the things you mention cause you to burn up calories faster than normal.There are certain rings that cause food to be required more often. They are: Searching, Sustain Strength and Regeneration. Also, you can't leave things (gold) and hope to get them on the way up. They won't be there. The game only generates empty levels (possible exception is if you fall through a trapdoor to a lower (deeper) level) when you go up. Thus, you must survive on the food you have while getting out but possesion of the amulet allows you to go much longer without getting hungry.
