Hi, I'm new to Slimming World (joined Monday) and new to these forums! I'm a bit confused about how Mullerlight yogurts are free! I've been having a look at the 'Syns calculator' on the SW website and had a go with a few different foods! I tried Mullerlights and entering the nutritional details it said that they are 4.5 syns! I also tried the new large pots of Activia fat free yogs and they come up as 4! Of course I take SW's word for it that they're free but just wondered how!!
