When I was on slimming world years ago, fakeaways were introduced. They were introduced as an alternative for once/twice a week takeaway, to stop you getting a takeaway. There are still calories in it. They were never a 7 day week thing. Yes, you can eat what you like on SW BUT free food is not a free for all it does technically still need to be portioned controlled to a degree so you can't have 45 potatoes in one day and expect a loss. That chipper burger she makes has a lot of calories and should be seen as a treat meal even if it is low syn or free. It is the same with the dalydish it was sw friendly meals but it was every single day.
If you look in the back of the book (I don't have one to hand so guessing measurements) it will say pasta 100g free.
Unfortunately weight loss has no magic fix, I wish it bloody did because I'm like a yo yo. You need a calorie deficit. The end. For me, I am an emotional eater and also love every food there is so I do need a controlled diet where no you can't eat a whole shepherds pie because it's free.
SW does work and it is a great plan to follow if you can stick to it. You also need to learn about fresh eating and calories alongside it.
Sorry that turned in to a bit of a rant
