Kwality with a "K"

Last week on the show we featured a nutritionist that told us about all the fad diets, and how they don't really work/don't keep the weight off/aren't healthy.
This week, we've got a guest talking about all the hot (read: fad) diets for 2005. When I asked our senior producer if this was a conflict, or if it made us look a little silly, she looked at me as if I'd just sprouted a second head, and that head was made of raw sewage.
