First the definitions.
A vegetarian is someone who does not eat animal products. By definition this includes animal flesh and products produced by animals(milk, eggs, etc). Lacto-ovo vegetarians do eat dairy and eggs. Ovo vegetarians eat eggs, but not dairy. Lacto vegetarians eat dairy but not eggs. Vegans are even more strict in that they not only not consume animal products of any kind, they also don't use animal products of any kind...including but not limited to honey, dairy, eggs, wool, silk, leather.
A raw foodist is a vegan that consumes more than 75% of their food raw or uncooked.
A living-foodist is a vegan that consumes more than 75% of their food raw, uncooked AND sprouted.
My BEST advice for someone planning to add more vegetable items to their diet is to buy a GOOD cook book for this. 2 wonderful books are Vegan Planet and Vegetarian PLanet. Both have very mainstream recipes in them for those meat and potato husbands

. The other thing is to stay away from meat substitutes for a while as they don't taste good to meat eaters for the most part and there are much better ways of getting veggies into the body. Another way is to make more vegetable for meals as side dishes.
Good luck!
