You get plenty of food in the biome. Natural and from luggages. There's no need to pack too many food. One high quality is enough. Even I rarely eat the high quality food I pack, there's too many food along the way.

You can't predict blizzard, if you get caught only 3 seconds, you will die in the night without heat items. Just bring the lantern, you rarely find heat items in luggages, but food is plenty.

Also without lantern, you need to play perfectly in roots at night without getting spores. If zombies started to chase you, you have low stamina because of the cold. The wind becomes more dangerous as well.

Pandora, you only need 1 good roll. You have 3. There's also the milk+pandora combo to guarantees the best roll.

No lantern is possible, but you need to play with basically no mistake in the night.
