Vegan and vegetarian are pretty different. I don't have a problem staying healthy (and enjoying a dinner or two out every week) without meat, but I think it would be extremely hard for me to do that and keep vegan. As I'm allergic to nuts a decent chunk of common substitutes are off limits.

Is it still possible? Sure, but giving up dairy/eggs would be a much bigger sacrifice to me than giving up meat, and it goes beyond just enjoying the foods - the effort required to maintain a balanced diet would have additional time and social costs that vegetarianism doesn't for me.

I think a much more fruitful avenue for persuasion (and this applies to vegetarianism too) is to encourage people to try cutting back on the products, perhaps start with one day a week meat-free. Different people may find it easier or harder based on a number of life circumstances, but the easier they find it, the more they may cut back.
