After years of being on the regime and seeing great results but still getting pesky breakouts especially if I didn't follow it exactly, I decided to try a low GI diet. Hence why I'm checking in because I cleared my skin with diet, too! My log is in my signature.
I still follow the regime but I also now avoid dairy and refined grains. I do have them on occasion although I really shouldn't because it sometimes leads to a binge and a breakout. But nonetheless, I go right back on the diet and my skin clears right up. Sticking to it 100% and 24/7 is very hard but well worth it.
I also supplement with green smoothies that is basically a way for me to eat more fruits and vegetables since I lead a pretty busy lifestyle and don't want to be in the kitchen all day.
I will say this: the diet is more effective than the regime. And I really, REALLY wish there was more research but telling you to not eat cereal or drink milk doesn't necessary help sell products.
I suggest everyone give it a shot!
