There are a couple of ways to make things easier as far as starving goes
When you build a character elfblood uses less food but takes longer to level up, from 2 apples to 1 per move.
If you gain a few achievements you can buy extra skill points during character builds allowing for higher overall stats. Perception, and charisma in particular are helpful.
If you level up perception and scout caches before going to them, you can potentially find a hunger charm, if you equip it, it reduces food consumption further by half. Mainly helpful when you have more than one party member.
If you have high charisma, you can beg dryads for food for free.
if you have money you can buy food from random travelers or stores, if you stay at inns they feed you.
Certain items are meant to be eaten like jelly from the slime, and baby spider from the spider cave encounter.
Giving blowjobs helps reduce hunger as well.
Edit: returning to the alter where you meet the angel allows you to return to the first town, you can also buy scrolls that allow you to return to town. I can't remember where but iirc it's the witches cottage in to forest to the right side of the first map.
