It’s not a new term, but one that’s being re-used heavily. You may have even read about it in Cooking Light/CNN.

According to the story in Cooking Light/CNN, it’s a pretty healthy diet. I think it makes sense and would be a good one to follow. Although I don’t know if I could follow it as you know how much I love my rotisserie…
