Any good diets for vegetarians?

I have been a vegetarian my whole life, will NOT start eating meat now. But I also didn't eat right at a kid. Whoever said vegetarians are healthy or eat right are liars cause there are plenty of us that do not. I started a diet 3 weeks ago eating mostly nuts, fruit and veggies. Kind of sucks but I've lost 8lbs. Does anyone know of a formulated diet for vegetarians?
