Another vegetarian diet I followed was "fruitarian." This one rejects killing plants, as well as animals. Basically, you eat fruits and nuts and seeds, and only vegetables such as brussels sprouts , asparagus, squash, tomatoes,etc where the plant is not killed. (this one was even harder to explain to others!)
I understand that distinction, I think you explained it well. Could you please give me some examples of a plant that is actually killed when it is eaten? I'm having trouble thinking of one.

And ... I bet you are the thinnest person!
