a vegan lifestyle actually requires a fair amount of effort and learning about nutrition

I was actually surprised by how little effort it really took? Like replace butter with margarine, slave milk with oatmilk and, unless you're baking, eggs aren't actually that important.

The rest is just choosing different meals. Roasted vegetables, fried rice, bulgur, beans etc. instead of steak or sausages or what have you. Get some starchy stuff, some veggy stuff, some proteiny stuff = heathy meal. Most nonvegans live less healthy than that. Then there really is only the B12 debate left, and if you want to err on the safe side just take some supplements. They're really cheap.

Sure, it wasn't 0 effort, but it wasn't exactly rocket science either. Just kind of look at what you're eating, throw out the non-vegan stuff and go from there. If you have any qualms about the exploitation of beings with a consciousness, who can feel the pain and suffering when their kids are killed just give it a try.
