My partner spent some time on SW, some of the recipes are good. I would definitely recommend the Pinch of Nom cook books.
But overall I wasn’t a fan of the system, it seemed to be designed more around it being a business (which I know it is). But the rules made progress slow, and kept people around to earn money off.
A calorie counting app like MyFitnessPal is better in my opinion, learnt much more about nutrition from a couple of months on that, than a lot longer on SW.
