@Quirkybee, I know we joined the forums around the same time and I was diagnosed T2 a week ago today, but I probably have an unfair advantage from watching my husband (T2 for 16 years) experiment with the food combinations until he came up with something that made a difference to his readings. He's now doing LCHF with me.
I'm now a week in and I have lost 3kg and, even though I've only had my meter for a couple of days, I'm seeing the readings starting to fall. Today I seem to be levelling out in the sevens. I hope I'll see a further drop tomorrow.
I did an experiment with breakfast yesterday and today. Yesterday's was scrambled eggs with two rashers of bacon. I'm very fortunate in working somewhere that has a canteen (food's a bit hit and miss on the diabetic front, but the breakfast choices are good). It filled me up and my reading dropped from 9.1 (fasting) to 6.6 (two hours after eating). Today I had two Shredded Wheat with semi-skimmed milk and Stevia. By the time I took my reading two hours later, I was starving. Blood glucose readings 7.8 (fasting) and 7.5 (two hours after breakfast).
Yesterday I skipped my piece of fruit (usually an orange or an apple). That made a difference to my readings too, I think,
I know which breakfast I enjoyed more!
I'm also walking every opportunity I can, which I think helps too.
There's no reason why you can't still follow Slimming World - the encouragement you get from other people is amazing. I did it years ago and lost three stone. If you're following the Easy option, take your choices from the Green and Red as before, but take into account all the good advice that's been posted here.
Don't lose heart. This is a great time to try new foods and new combinations.
