I do kiss occasionaly with great results. My skin gets more clear, so does my thinking, and my weight goes down. Unfortunetly after about a week I go nuts and start adding foods back in

For me when I did KISS I eliminated all dairy and any kind of LC product. I had all the meats, veggies and fats that I wanted. I also used fitday to make sure I was getting enough protien, keeping my fat calories around 70%, and getting at least 1200 calories (with kiss the veggies are so low cal I would get to few if I didn't watch)

Like I said it worked, but the bordom and the pain of balancing everything got to be to much. It really eliminated cravings though to where even when I got off I had no desire for sweets, protien bars, or any other overly processed foods.
