diege I follow SW, I know it's not popular in Mumsnet! I lost over 3st and kept it off. I know it's less flexible than calorie counting, but I definitely eat a lot more healthily then I did on WW when I could save my points for booze and sweets!!
I find it's ok for family meals, things like chilli, spag cook, stir fries, sausage and mash, fish pie, Thai curries, Indian curries we all eat the same. I might have low cal sausages instead of normal. If we have fajitas I have lettuce leaves instead of wraps.
I tracked calories for a day out of interest and it came out as about 1700 for me, which seems reasonable.
