I went all the way with veg. As faaaaaar as you can go. Vegetarianism turned into veganism, which eventually (3 years ago) turned into the raw food diet. I did see dramatic health improvements on the raw food diet (complete erasure of moodiness, brain fog, blood sugar swings, nagging fatigue and annoying minor health complaints), enough to motivate me to keep on with it. My Raw Infatuation eventually led to a mostly fruitarian diet, with me completing a one month stint on all raw fruits and veggies, with no overt fats last summer.
