Well, although I don't think you'll find any studies on the low-carb diet causing liver problems, I have to say that I encountered more problems with my gall bladder when I was on a low carb diet. You can still eat protien and get your carbs from LOTS of vegetables. Make sure you have a big salad along with that steak.
I'm the local non-vegan around here. I got really sick being a vegan, I now know that's because grains and me don't mix. If you check out www.mercola.com there's some info, it's very healthy and you can eat meat. But eat lots of veggies, that will help clear up your face as well. To find the Liver Flush click on the link at the top of the Curezone page that says Cleanse and the liver cleanse will be there.
