I've been a vegetarian/almost vegan for years, and if anything my nutrition has improved. It's a knee-jerk reaction for healthcare practitioners to be worried when you say you're cutting out animal protein. Just be careful not to overdo the carbs, which is super-easy to do. I am not a skinny veggie, by any means, lol. But I did cut my cholesterol wayyyyy down after I stopped eating meat, as well as my fasting glucose. My doc was pleased, and said nothing when I told her how I was eating (but I also supplement with Vit D because I live in a not-super-sunny state). I will say that I eat fish and eggs, once in a great while, but they are usually locally harvested/caught.
