Ooohh.....sorry, have no idea, but have always wondered this myself. I'm only allowed the cranberry and peanut cause I'm on ss and have often fancied more than one. I find it hard to believe it would really make a huge difference, given that people have more cals atc. on ss+ and 810 upwards and still get fab losses. Maybe the carb level would bee to high? Interested to find out.... xx
