I too follow slimming workd for weight loss, but I simply don’t eat all the free pasta, potatoes and rice you want,
I find I can have little portions of rice and wholewheat/lentil pasta with plenty of veggies, fruits and healthy fats and protein....I sometimes use my syns for healthy fats like nuts and avocado,
For me slimming world is so far working and helping my diabetes, I’m very new to this still but from what I’ve realised everybody with this condition is completely different and what one person can’t eat another might, some can handle more carbs than others, so do what works for you.
Slimming world may not help me in the long run and maybe it’s the best thing I’ve done...there’s a couple of people in my group that have t2 have reversed their diabetes with slimming workd just by losing 10% of their body weight, and they can eat a little rice, pasta here and there but it all about portion control and moderation.
