It might not be to the point of permanent damage, but you certainly wouldn’t be feeling good. You probably wouldn’t be iron deficient, but a lot of vitamins are only stored in small amounts in the body.
True, but people can go on extended fasts without malnutrition concerns. Usually those are in overweight folks though (at least what I am thinking of) so maybe they have deeper reserves.
I did my phd studying the chemistry of vitamins, specifically, and iron, specifically. Scurvy can kick in after a month. If this person is a woman and menstruating, anemia can kick in within a month.
Jesus, Lemmy is full of the same arrogant fucktards as reddit.
