I was vegetarian for years, but was told by my GP that I just HAD to start eating red meat. Like LionsandBears, I was a bad vegetarian - I didn't really substitute foods well and basically just ate what DH ate but without the meat. One of my issues is that i'm allergic to most raw fruits and vegetables, as well as nuts, chickpeas and other vegetarian friendly foods, but my biggest problem is that I have a B12 deficiency. I've been tested for all sorts of things and doctors can't find a reason for it, but even with supplements and/or injections i'm fairly low so my GP said I HAD TO EAT RED MEAT!

I struggled big time when I started eating meat again, took my body some time to get used to it and psychologically it took ages (I was also a vegetarian for ethical reasons). Even now I probably don't eat as much red meat as I 'should', and I am very selective about what i'll eat. Having said that I can't imagine going back to a vegetarian diet as i'm just too limited with my allergies.
