I can't tell if you are serious or not .
Origins,wow I don't understand how someone can not like vegetables. If done with the right food, the right way, I'd be sad if I didn't have any. I mean imagine eating steaks with bread all the time or something, I'd much rather have potatoes. Or I mean when you have so pasta with good pesto, I really like to have some broccoli with it.
I just don't think that unhealthy fastfood stuff that many eat is something that they really like, if they had the time, or weren't lazy, they would prefer something else, which would probably be something healthy.
I can understand it, because if I didn't eat for 8 hours straight for some reason (being lazy, too much work, etc..), and didn't want to spend another 1.5 hours making food for myself, I would just eat some chocolate bars or go get myself some kfc. If you actually spend time to make yourself food that you want, when feel like it, you'll only get fat or unhealthy if you just eat too much of it.
