Last time I did slimming world i ate meatballs and westlers tinned burgers till they came out my ears! I did always think it was odd they were free though - seeing as they full of fat! And stewed steak used to be free - but the fat on that when you open can made me want to vomit - so never understood how could be free. They obviously had a re-think!
people have lost weight on SW in the past eating meatballs...
i asked why things could be free and then not, and was told that if you have lost weight using the old syn values of things - and you want to continue treating them as free - then do do - others have lost weight, but if losses become sluggish then they are things to consider treating as syns.
