Yeah, well I personally haven't turned orange, but I am not doing a lot of juicing, I just buy it fresh 4-5 times a week, about 16-20 oz. of carrot/beet/apple a day. Plus that's usually followed by lunch so maybe some of the fat gets mixed with it.
Like someone else mentioned, I think it also has something to do with the Liver Cleansing itself, and something about the blood cells...
