I have thought about doing this lots of times, I am not sure how old you are but like noahsmommy said make sure you get enough protein, I think during the growing years you just have to be extra diligant.

My daughter rarely eats meat and her pediatrician doesn't seem worried at all. I know my kids 12 and 14 are very aware of where food comes from when I was growing up we just didn't question but now I my kids have got me thinking about it and it kind of grosses me out too.
