I became a vegetarian about two years ago, and have since gone through periods of veganism as well as fish-eating. My choice was mostly motivated by ecological reasons, but I became curious about the health effects of vegetarianism after I noticed changes in how I felt after a change in diet. I found I lost weight as a vegetarian, and had more energy; I also had significantly increased energy in the first month of veganism, though this effect wore off eventually. I wanted to gather more observations to discover if my assumption that vegetarianism was healthier was, in fact, true, and true for people other than myself.
