So while the initial decision to go vegan may be a preference, no one should assume that it isn't a requirement for them to continue to eat vegan.
While medical school was a while back for me, and I'm not working as a gastroenterologist/GP/relevant specialty, I've never heard of complications from moving from a vegan to a normal diet. I'm pretty confident that vegans can eat a bacon sandwich/steak/burger if they want to without worrying about some kind of re-meating syndrome.
