Cheryl I'm on R1P2 I was wondering the same thing. My sister who is also doing the diet eats it so I thought I'd give it a try. She always says that the same food may work for some and not others. I also tried brussel sprouts. I don't know which one it was but I GAINED 2 lbs yesterday!!! I was mortified!! I even increased my water intake by 1L. That's just my experience with it. I hope it works for you if you decide to try it.
