I, like many others here, found reducing carbs the best way to reduce blood sugar.
Low carb, ie less than 130g a day (or much lower for many of us), can get you into remission fast before you progress to T2 instead.
Don't look at the Eatwell plate - that doesn't suit T2s - or think brown is better than white, it's all carbs.
I aimed for less than 85g a day down from 100g at first and no more than 30g in a single meal (including drinks). I know that some need to cut much more but I started low carb as soon as I was diagnosed and that seems to help.
You could join the lowcarbprogram if you need something more structured to get you through the first few weeks, and in some areas you can get an NHS voucher to cover the cost.
Otherwise cut hidden carbs as well as obvious sugar, think about the foods you love most and find suitable substitutes.
