You could also check with Rachael and Ed at For the Health of it. I went vegetarian for two years lost 30lbs and never felt better. Started eating meat after I starting spinning at balance. I still probably only eat meat once a week. I have learned that the whole protein thing and meat is very over rated. One of my best friends is a body builder and has never eaten meat. If you have a balanced diet with lots of veggies, fruits, and whole grains your protein levels will be fine. The only time you may run into problems is if you begin working out at a very high level.
