all the countless benefits of fasting
xyz should be different when fasting.
Do you actually have any evidence
@all: Can we stay on topic please?
The general forum is meant to be about issues related to the game. Discussion about RL health issues is not quite on topic here. There is a lot of misconception on both sides of the spectrum. This is likely the reason why the posts implying certain health claims got voted down. So let's not go there.
Remember: We're talking about a game that is inspired by real life and meant to be authentic. So we can reason about what might seem plausible but really have no need to discuss the actual thing – nutrition – as such.
In the same vein, a plausible effect of drinking alcohol in the game would be to increase your charisma. Yet, most people will agree drinking alcohol in RL might not increase your chances of convincing someone.
It's more about stereotypes.
That all being said, I agree with others saying there will likely be starvation and associated effects. Personally, I imagine the effect will be chosen to be plausible and to nudge the players towards a certain way of dealing with the situation.
