why don't you want to eat food?
afp isn't that great of money until you get 85 slayer. you might aswell power train combat then make money another way, your options are. ghouls, chaos druids, slayer (setting up your bot each task), dusties for crims and an occasional chain. If you're going to do chaos druids make sure you bring a macaw = increased herb drops.
I personally bring a bone crusher + dg dneck to most camps, the exp really builds up tbh + faster combat exp if you pray whilst doing it.
I get 80k-90k/hour at ghouls, chaotic rapier, ext str+atk, bone crusher + dg d neck w/ turmoil if you have. I dont fuss over familiars too much, i may bring a bunyip or ice titan if necessary but usually not. I wear +30 prayer and the rest is maxed str gear, not to fussy on def as my familiar usually heals me. only loot crims/blues and effigys. I lose about 250k/hr doing this but it is well worth it + rapier degrades slower because of single way combat
if you're doing chaos druids then go to yanille dungeon, with macaw, picklock and loot irit+ and all charms. max str, but i only did range there so i wouldnt really know
