There are better ways to obtain food than gathering in terms of efficiency in all aspects (time, money, stamina and even also imbuements invesment) if either way u are interested somehow into gathering u would like to know:
- Diremaws/deepworms: they drop tons of meat/ham/mushrooms (in warzone 5-6)
- Feyrist mobs give a lot of food (but beyond mushrooms/cave turnips that food weights a lot too)
- Coryms drop a big variety of cheese (can be killed at port hope and venore)
- Mutated tigers drop a lot meat (can be killed at yalahar alchemist quarter or zao before the boss of fire portal)
- Most mammal drop meat in tons (can be found all around tibia)
- Demon and in general ferumbras ascendant mobs drop fire mushrooms (demons could also be found at yalahar magician quarter/edron as unique mob to hunt)
- Wyrms also drop Dragon ham ( in liberty bay and drefia)
- Dragon ham is the food who fullfill most hungry in the game
- an excellent place to multi task it is nibelor, there u can kill polar bear, winter wolf and penguins (all these drop food and the spawn is enoughly good) also u can do ice fishing there and make runes so probably that's the easiest profitable spawn ever.
- "passive mobs": those mobs who doesn't attack but run away doesn't waste ur stamina and ofc u would waste a ton less of money killing them as far as i know those who also drop food are: deer, pig, rabbit, sheeps
- there are other places to kill dragons as darashia and biggest wyrm place is drefia's one
- as much as these food fill a lot of hunger if u have to loot it will weight A LOT and in vocations as mages u will run out of cappacity easily.
If instead u are looking for ways to obtain the best food in terms of efficiency u should know:
- u can buy a lot of food from NPC which is easier, cheaper and faster than gathering it
- Fire mushrooms is the best food in terms of weight/satiety but can't be bought from npc have to be looted from demons
- Brown mushrooms is so far the efficientest food cuz their weight/satiety/price/ease and can be bought from luna at edron 10gp each
- as free u should look at market for brown mushrooms/dragon ham or buy white mushrooms instead at Venore/kazzordoon
- Dragon ham is the best option while at dp but can only be obtainable as drop from dragons in general
- Ham is also a good option to take into account at the hour of buying food to make runes as their ease and satiety stats
