You might have been in a situation where your bag is full of those items you collected from PokéStop when playing "Pokémon Go". It is hard, especially when you are still at a low level, to decide what to remove from your bag to make space available for future items when you visit PokéStop - as everything seems important.
Gaining a level in "Pokémon Go" is much easier when you are still under level 20. Hence, do not feel the pressure to remove anything - unless the items you have in abundance. Those Pokéballs are useful for battle, so get involve and catch all of the Pokemon you can find. Each Pokemon gives you the experience point, especially Pidgey (the easiest Pokemon to evolve as it requires only 12 candies). All evolution scenes will give you a massive amount of EXP so Pokéballs are essential. So before you reach the level 20, common candidates for removal are:
Revives and Potions, together with Nanab Berries.
When you are in a low level, means that the Pokemon you encounter along the way are also in low level. You will not be able to successfully compete in Gym as most players have cornered the realms with some pretty strong Pokemon (unless the Gym is left empty, you can try your luck by assigning your chosen Pokemon to be in the Gym). Don't hesitate to throw away Nanab Berries, as they're rather useless.
Keep the lucky eggs and lures. Use them accordingly, these items can help you to gain more EXP. Once you hit Level 20, but before you hit Level 25, your priority list will stay almost the same. You can remove these items:
Potions as they become inefficient and very slow to heal, and don't really matter most of the time unless you are trying your luck in gyms with rather weak Pokemon. Nanab Berries will remain useless at this stage. It's safe to throw them. You can also remove revives, but don't overdo it because you may need them when your Pokemon got knocked out.
Above Level 25, your "safe-to-remove" list grows a bit, as you are unlocking higher tier items. It is also wise to start conserving Revives. Potions and Super Potions can be removed, to make space for Hyper Potions. You may also start to just throw away those Pokeballs, as Great Balls and Ultra Balls are more relevant at this stage of the game. Nanab Berries still remain useless, just throw them away. Once you finally hit Level 30, you already know what to keep (Hyper/Max Potions, Normal/Max Revives, etc).
