If you go vegan or even vegetarian for a short amount of time (probably a month or 40 days like some recommend), you won't "love" meat anymore. It's a combination of the body liking the foods that you regularly feed it, and that your mind will justify your actions. You may remember liking meat even long after giving it up, but many people never go back to eating meat nonetheless.
This happened to me! I was started by cooking vegetarian food for myself but ate meat when I was invited to someone else. I went three months without eating meat and after that I couldn’t stand the taste. Nowadays I even think it smells bad when someone is cooking or grilling meat.
