My children and oh all eat the same meals. None of them need to lose any weight as they are all on the low side of normal. I still cook SW friendly food, but add in extra cheese etc to give them the extra calories/fat that they need.
I cook seperately for myself, but I've always done that. Mostly becuase I don't like spag bol, chilli etc. During the week, I am pretty much a 'meat and salad' girl.
I always cook a SW meal for myself and oh at the weekend - this weekend we had chicken tagine which was absolutely fantastic!!!
