This is news? Daughter of a wife's friend went full vegetarian some years ago. She wasn't all that attractive to start with, but after a couple of years she resembled something found in Dachau and her hair started falling out. After quite a while of her trying to figure out what was wrong with her (after all it couldn't be her idiotic diet) she went back to limited meat and voila her problems mostly went away.
We are all different in the way we react to things.
The soy-based crap many of the veg fanatics eat is disastrous for the thyroid. One symptom of thyroid illness is hair falling out. Just saying'.
Yeah, I’ve seen it dozens of times in my life. Some modestly attractive, usually shy girl gets emo about eating the poor animals and goes vegetarian. It lasts a couple of weeks or she looses weight, skin tone, posture, hair quality, hair, energy, alertness and whatever looks she had. Get her back to a reasonable diet and it all springs back.
I’ve never seen a male do it. I think they cheat.
