I am considering switching from a vegetarian to an omnivore lifestyle because I have been tired and unhappy for the few years I have been vegetarian. A friend pointed out that I may just need iron in my diet. Another thing I am considering is that I have actually gained weight as well, due to my increased consumption of carbs. So if it's hard for me to get protein, which makes me eat carbs, which make me lifeless, mopy, and fat, could integrating meat into my diet help?
