By RAW goodberry cannot heal. RAI and officials answers are more important than RAW

[Belier]

You discuss and discuss, and forget the most important thing, if you eat like 10 goodberrys for some hps: Will you get fat doing this ? I mean, one goodberry should have like 2000-3000 kcal if it's enough for one day :)

It is magical sustain, it has nothing to do with kcal lol
