I'm doing it and really loving it. Losing a steady 1/2 pound a day.
Breakfast I find is the hardest meal of the day as it easily uses up my HEa and then I can't have my milky coffee or tea.
I'm trying the overnight oat pots and they are lovely. If I'm at home I like re fried (with 2cal oil spray) potatoes, 1 syn quorn sausages and beans as it fills me up.
I'm a big snacker, I've stocked up on tasty fruit and leave a fruit salad in the fridge. Or a Greek salad without the cheese.
I think the secret seems to be to make everything you eat contain a minimum of half veg (Speed foods and normal).
Lunch I like jacket potato and last nights leftover, chilli, stew, bean (all stuffed full of hidden veg) etc.
Or smoked salmon frittata which can be cold and wrapped instead of sandwiches.
Or the pasta and sauce made up with extra chicken and mushrooms and left to go cold (syn free)
Evening meals can all be frozen ahead. Loving the tasty curries with extra rice and a poppadom (2 syns). Spray frying banana adds a sweet side to a curry which is nice.
I do a stifado beef which is lean beef cooked with passata and baby onions served with rice and green beans.
I've found Iceland online do slimming world products Syn free meals and sauces.
The haddock rolled in egg then raw smash and 'fried' is yummy. I serve it with mushy peas and oven syn free chips.
Another recent discovery was sweet potato, normal potato and onion hash browns. Cooked with spray oil and served with a fried egg.
I find I only need to use my syns in cooking, odd ingredient here and there. And in the flavoured yoghurt in the overnight oats.
I'm not overly active, my syns each day are between 3-6. I'm middle aged.
Chocolate fix is the Cadbury lites.
We have had the same meals twice but I do try to plan ahead so I'm excited about my food. There are good recipes online. All the Iceland foods for slimming world has the recipes on the back so you can make them again.
I think veg and variety is the key.
I didn't join a group as I found it tiresome and expensive. I have my 2014 books, a SW buddy and weigh in once a week.
