LolSuppose these diets have guidelines and "do's and donts" for a reason. If people wantto take the risk and drink fizzy juice, etc etc, they may still lose weight but its still not really part of the diet guidelines. everyone is different. what i may get away with, someon else may not.
Hence my next point, mark and mike.....cheats! haha
